BBRI – Annual Report 2013

Societal changes are at the origin of numerous
challenges that must be successfully met by the sector.
The BBRI resolutely
turned towards the future
It is hardly a secret to anyone that the construction sector is constantly developing and is undergoing
major transformations. Societal changes, indispensable not only in order to reduce our CO2 emissions
into the atmosphere, but also to make our buildings perform ever better, are at the origin of numerous
challenges that must be successfully met by the sector. The Institute wishes to play a major role in
this effort and so it set itself a course in accordance with the work plans of its Technical Committees.
This collective approach, conducted in synergy with the authorities and the professional organisations,
constitutes the very essence of its action and determines the core priorities for the coming years. These
priorities are divided into six areas, which are detailed in the following pages as well as in the vision report ‘Cap sur 2015’ (‘Heading for 2015’) available for download on our website www.bbri.be. These priorities were presented to a panel of more than 400 participants during an exceptional evening organised
for all the builders of the future and professionals concerned with the action of their Research Institute,
such as the members of the Technical Committees and Working Groups.
With regard to disseminating information, the BBRI extensively revised its website in 2013. It is now
possible to sort all of its content by trade or by theme. A clear and simple way for professionals to create
a bbri.be in their own image, by eliminating the information they do not directly need. The Institute’s
logo was also given a makeover: a stylised dodecahedron referring to history, but firmly anchored in the
current dynamic by its animating movement and by the ‘.be’ reference.
The creation of a quality framework, which constitutes one of the six aforementioned priorities, was notably initiated in the area of hollow wall injection. In addition to a certification of products via a technical
approval procedure, the companies practicing post-insulation of hollow walls can now highlight their
know-how by the means of a certification entailing a training obligation and the knowledge of the relevant reference documents (the STS’s and the TIN’s). The efforts do not end there, and other techniques
remain to be envisaged, particularly as regards the energy performance of our buildings.
However, the BBRI does not limit its actions to technical aspects alone. Since improving competitiveness in the sector is one of its essential missions, the solutions it proposes not only have to be reliable,
but also economically affordable.

Introduction
With its 237 employees, the BBRI is one of the largest collective research centres in Belgium. A well-oiled machine
that operates according to a bottom-up approach which is unique in Europe and which is expressed through the
annual work plans of its Technical Committees.
The BBRI currently has eleven vertical Technical Committees (TC’s), each dedicated to a particular trade. Each TC
is chaired by a contractor and orchestrated by several engineers appointed by the BBRI, and includes a core of
representatives from the trade concerned, supplemented by experts (manufacturers, consultancy offices, etc.).
These Committees ensure that the Institute focuses on the practical problems encountered by tradespeople. They
orient the research towards areas of interest to the sector and define their needs in terms of publications. Three
more horizontal Committees are devoted to hygrothermy, acoustics as well as consultation with project designers.
Having always been a pioneer, the BBRI is constantly anticipating the implications of certain fundamental movements on our way of building. The determination to make the construction sector evolve so as to take account of
societal, environmental and economic issues imposes a radical change of course and impels us to transcend the
disciplinary divisions.
Following the lead of the ‘Cap sur 2015’ report, the contents of the new Annual Report are henceforth being

BBRI.be
2013 version
The BBRI’s website, its central communication tool, was given a new look at the
start of 2013. The information it offers is
now divided into two distinct spaces that
you can discover on the home page:
• ‘Information and Assistance’ brings
together by trade or by theme all information or all useful support within the
framework of construction or renovation
works
• ‘Research, Development and Innovation’ focuses on all of the Institute’s activities aimed at developing the expertise
of tomorrow and preparing for the future.
The actions of the Institute described in the following pages logically
follow a thematic classification (Energy and Environment – Comfort,
Health, Accessibility and Safety – Building Materials and Systems –
Technical Installations). Each theme is declined along six main areas
that largely define the course to be taken by the BBRI in the coming
years. These are presented below and illustrated by an icon that
constitutes a benchmark for each of them.
The ‘Information and Assistance’ space
is distributed over eleven ‘trade’ pages
corresponding to the eleven vertical
Technical Committees, and over four
thematic pages. This division allows
professionals to access the desired information very quickly, which is especially important in light of the fact that
over 7,200 documents are available. The
success of this new site was proportional
to the time and energy spent creating it:
in 2013, no fewer than 820,000 documents were downloaded, representing
an increase of nearly 20% compared to
the previous year.
The different projects described briefly throughout these pages are
further detailed in the ‘project’ fiches which can be consulted in the
database available at www.bbri.be. A list of the ongoing projects is
annexed to this Annual Report. This list also mentions the subsidising bodies.
The structure of all the ‘trade’ pages is
identical and notably includes the ‘FAQ’,
short questions that are often asked and
which require a simple answer, usually
accompanied by a link to a publication.
organised thematically, without splitting them up between the different disciplines. This permits us to interconnect the different trades
so as to better meet the challenges of tomorrow.

Energy and Environment
The energy performance of buildings has
advanced greatly and will be called upon to
improve considerably in the future, for both
renovations and new buildings. By 2021,
those will be obliged by Europe to achieve
nearly zero-energy consumption levels.
Beyond the energy performances, taking
into account and reducing the global impact
of buildings on the environment constitutes
another major challenge.
The necessary energy
1
Energy
construction
The creation of buildings with
nearly zero-energy consumption
requires above all developing an
energy-efficient envelope of the
building. To do this, it is necessary to
have specially adapted materials at
one’s disposal and to use them.
In 2013, many research projects were carried out on thermal
insulation techniques for buildings, on outdoor joineries
and on shading devices.
The projects dedicated to thermal insulation techniques
applicable to both new construction and renovation
concern the external insulation of facades (e.g., project
NIB ‘ETICS’(Nieuw Industrieel Beleid, new industrial policy)).
In the area of joineries, the BBRI conducted several studies
such as ‘DuraPerf’ and ‘ISOLA 2020’. These projects seek
to optimise outdoor joineries in terms of both energy
consumption and all the other performances expected from
this type of joinery.
Within the context of the visual comfort of the occupants
and the prevention of overheating, the ‘PROSOLIS’ project
focused on the proper characterisation of the energy and
visual performances of shading devices in order to permit
the actors of the construction sector to choose this type of
product with full knowledge of all the relevant facts.
Many actions were conducted on the theme of the
airtightness of buildings. Several seminars, information
sessions and conferences were organised during the
year. This dissemination of information is directly fed
by the results of research projects conducted in 2013
(the ‘Etanch’air’, ‘DREAM’ or ‘Luchtdicht bouwen van
A tot Z’ projects). These deal with the durability of the
airtightness performance of products and assemblies, the
identification of practical solutions that can be applied
on the worksite, the development of optimised technical
details as well as the direct assistance to building
companies, notably on the worksite. This dissemination of
information is also supported by the actions of the thematic
information platforms ‘TightVent’ (www.tightvent.eu) and
‘AIVC’ (www.aivc.org), to which the BBRI contributes.
In 2013 the BBRI coordinated the development of the technical reference document for the competition ‘Bâtiments
exemplaires Wallonie’ (‘Exemplary Buildings in Wallonia’,
www.batiments-exemplaires-wallonie.be). An exemplary
building is one that is notable in the way it meets a series of
sustainable construction criteria, which are thus no longer
limited solely to the energy issue.

is optimised for all of the

to design and construct very high-performance office buildings at limited expense, was finalised in 2013.

water- and airtightness of this junction.
In the area of the airtightness of buildings, throughout
the year the BBRI also worked on the development of a
Technical Information Note integrating numerous practical
details.
Example of pressurisation test performed on a large building.
The requirements of the regional regulations on the energy
performance of buildings (EPB) have strengthened greatly in
recent years and will be further reinforced in the coming years
for both new buildings and renovations. Indeed, by 2021
Europe will be imposing nearly zero-energy consumption
levels for new structures. The regulatory calculation methods
and the calculation tools integrating them are constantly
being developed by the regional authorities. The BBRI
supports them via the EPB platform, which brings together
the three Regions and is designed to facilitate the coherent
evolution of the regional EPB regulations. In addition, the
BBRI participates in the concerted European action dealing
with the implementation of the reformulated European
Directive on the energy performance of buildings which is
at the origin of these EPB regulations (project ‘EPBD CA3’).
The actions aimed at setting up the training offer in order
to apply the EPB regulation continued, and this particularly
with regard to the impact that these regulations have on
the trades.
Multiple actions devoted to constructional nodes were carried out. The
‘STAR’ research continued. This project is designed to provide the construction sector with technical details

optimised in terms of energy and

the junctions between the joineries and the rough structure were also conducted (prenormative project ‘Raccord

the optimised technical solutions it proposes, this project
also seeks to establish a test methodology for evaluating
The energy renovation of existing
buildings constitutes a major challenge – both today and for decades
to come. Several research projects are
being conducted within this context.

renovation
The ‘RENOFASE’ project is intended to
remove barriers – whether technical
or not – to the renovation of existing housing. Renovation projects were also followed, for example, through the
‘RENO 2020’ research project. The Flemish administration
responsible for energy (VEA) published a brochure established by the BBRI and devoted to the internal insulation of
existing facades.

The multidisciplinary research platform ‘Brussels Retrofit XL’ (www.brusselsretrofitxl.be) focuses on the renovation of dwellings in the City of Brussels. Coordinated
by the BBRI, this consortium is composed of 13 research
partners from the Institute and the Brussels universities.
These studies directly influence the (future) valorisation
and concern a wide range of subjects: wind energy, energy
storage, external thermal insulation composite systems
(‘Innov-ETICS’ project) and prefabricated renovation systems (‘AIM-ES’ project).

than 80% of whom indicated that they were highly satisfied
with the content of the training.
With regard to publications, the Institute maintained its
efforts of 2012 to supplement the theme of the airtightness
of buildings. This time the BBRI staff concentrated on
analysing the influence of this new theme on the work
of certain specialised trades, among others tilers and
plasterers. A second article was also dedicated to the
technology of internal thermal insulation. After the
diagnosis of the envelope, it was time for the analysis and
dimensioning of insulation systems. The environmental
impact of the components of buildings, including that of
flat roofs, was also addressed.
External thermal insulation composite systems (‘Innov-ETICS’ project) form part
of the scope of the multidisciplinary research platform ‘Brussels Retrofit XL’.

In the Walloon Region, the BBRI worked to establish the
second version of the procédure d’avis énergétique (energy
auditing procedure, PAE) applicable on a voluntary basis
to existing housing (‘PAE 2’ project). In recent years, the
Institute has also supported the application of the energy
certification system for existing housing (‘Support certification énergétique en Wallonie’ project) and assisted the
three Regions in the development of the energy certificaRénovation

in more than 140 training courses on this theme. The Roadshow concerning constructional nodes, organised in partnership with the Fédération des entrepreneurs généraux
de la construction (Federation of General Construction Contractors, FEGC), constitutes a good example of successful
collaboration. The presentations, which mainly addressed

Approvals in the Construction Sector, UBAtc). These ATG’s
also mention one or more competent installers who are able
to implement the insulation system under consideration.
The certification is accompanied by certain conditions: the
construction companies must fulfil specific requirements,
the insulation installers must have received training from
a holder of the ATG, and the persons responsible for the
preliminary inspection of the worksites must have taken a
specific training organised by the BCCA.
The contractors can send to the owner a declaration
attesting that the works have been executed in accordance
with the STS 71-1 and the related ATG. In this case, the BCCA
must receive a report on the preliminary inspection and the
works performed, and the construction companies must
communicate their planning in order to take samples on
the worksite for control tests.
The objective of this recently-established quality framework is to strengthen the confidence of public authorities
and owners in these insulation techniques and in the certified installers, so as to maximize the number of insulated
hollow walls.Cadre

Innovation is stimulated notably
through actions such as the Technological Advisory Services. In the
Walloon Region, the Advisory Service
‘RENO-2D’ supports the actors of the
construction sector in order to proInnovation
mote innovation, mainly in the area
of technologies improving the energy performance of buildings. In the Brussels-Capital Region, the assistance to the
sector in terms of energy and the environment is generally
provided by the Advisory Service ‘Eco-construction et
développement durable’ (‘Eco-construction and sustainable development’).

In 2013, the Technology Watch (www.technologywatch.be)
reached its cruising speed. This service is an initiative of
the Technological Advisory Service ‘Eco-construction et
développement durable’ in the Brussels-Capital Region,
which is constantly searching for new materials or adapted
building methods and better organising techniques. Within
this framework, the Technology Watch offers the necessary
support to the sector by keeping it informed of the latest
innovative products.
Where a Technological Advisory Service supports companies in technological innovation or improvement of the
technical expertise, an Incubator offers young companies
the space and support they need in order to successfully
Since then, no fewer than 750 people have received training from the BCCA and nearly 500 have already obtained
a certificate permitting them to perform the preliminary
inspection. In Belgium, 79 contractors hold one or more
certificates (allowing them to perform the post-insulation
of hollow walls by various on-site fillings of the cavity).
In 2013, the first complete year during which this quality
framework was applied, post-insulation was performed
on nearly 15,500 worksites (2,000,000 m²). This number
should increase to around 20,000 in the coming years.

Since 1 July 2012, the Flemish administration responsible for energy (VEA) does no longer grant subsidies for
post-insulation of hollow walls by filling the cavity unless
the owner can provide a declaration of conformity. The
websites of the VEA (www.energiesparen.be) and of the
UBAtc (www.ubatc.be) include a list of installers certified
for the implementation of this technique.

start up their activities. Operational as of 2015, ‘Brussels
Greenbizz’ is an Incubator which will focus on the theme
of the environment and sustainable construction in the
Brussels-Capital Region. In this context, the BBRI will be
responsible for technological networks.
Innovative research projects were also conducted. For example, the ‘PERFECT’ research, which is devoted to on-site
evaluation of the real energy performance of the envelope
of buildings, continued in 2013. This research is accompanied by an action organised on the international level
within the framework of the International Energy Agency
(Annex 58 of the ECBCS programme (Energy Conservation
in Buildings and Community Systems), project ‘IEA ECBCS
Annex 58’). As for the ‘SIMBA’ research, completed in 2013,
its purpose is to encourage the use of digital simulation in
order to help the construction sector.
In the field of lighting and natural light, studies were carried
out in 2013 with a view to supporting future urban-planning
regulations. They evaluated the impact of height and of the
distance back from the street on the buildings to be erected
in the urban context (‘Development RRUZ’ project) and thus
facilitated progress on major urban development projects.
The environment
The environmental impact of a
building mainly depends, on the one
hand, on the choice of the materials
and their renewal during the building’s
life cycle and, on the other hand, on
Energy
construction
the energy consumption during the
use phase. Moreover, the behaviour
of the occupants in terms of transport and domestic
management can also have an impact on the environment.

district within the framework of the ‘Development RRUZ’ project.

A clear description of these impacts (materials, energy,
water, mobility, etc.) will ultimately make it possible to
make well-grounded decisions.
It is clear that the environmental impact of materials is proportional to the improvement in the energy performance of
the building. For passive buildings with nearly zero-energy
consumption or even with positive energy, the environmental impact of energy consumption is thus lower than that of
the materials used.
The influence of the use of materials on the environment
is considered throughout their lifetime (extraction of raw
materials, production and transport to the worksite, processing on the worksite, necessary maintenance, replacement and, finally, demolition and landfilling or recycling of
the rubble).
In this context, the BBRI actively participated in the works of
standardisation committees both on the international (ISO
TC 59 SC 17) and the European (CEN TC 350 ‘Sustainability of
construction works’) levels. Within this framework, the Institute is the sectoral operator for the Belgian construction.
At the request of the industries, the BBRI also conducts
studies in order to analyse, according to the methods
established in the European standards, the impact of a
construction material on the environment. So, the BBRI
participates in the drafting of the Environmental Product
Declarations (EPD) that will serve, in the short term, as a
basis for calculating the environmental impact of buildings
or even whole districts.
The industry, the contractors and
the BBRI have undertaken applied
research on new methods and
materials which make it possible to

project ‘LEEMA’ focuses on innovative
insulating materials and on concepts of insulating masonry
with a low environmental impact. Launched in 2013 in Wallonia, the collective research project ‘RenOZym’ strives to
find new techniques for cleaning facades, roofs and terraces without losing sight of such important aspects as the
harmful effects of implementing the works on health or the
evaporation of chemical products or biocides. This project is
developing an ecological technology thanks to new formulas based on micro-organisms and enzymes. The Walloon
project Greenwin ‘LOWEMI’ also devotes great attention to
the environment and health. It seeks to develop interior
coatings which emit very few harmful substances during
both the installation and the use phase.

For years the BBRI has been focusing on the use of recycled materials as a solution for reducing the environmental impact of construction, and more specifically that of
materials. Launched in 2013, the NIB project ‘Stortklaar

ecological concrete (concrete based on recycled granulates). This project strives to promote amongst advisors,

Within the framework of a synergy between the industry and the research
centres, the project of the Environmental and energy technologies innovation platform (Milieu- en energietechnologie Innovatieplatform or
Innovation
MIP) ‘GREENASH’ developed a treatment process in order to valorise clinkers qualitatively in
both material and energy terms. The use of granulates and
dredged sediments is important for the entire construction
sector. For this purpose, a consortium of which the BBRI
is a part examined, within the framework of the MIP project ‘V-AMORAS’ (finalised in 2013), the possibility of using
dredging sludges in certain construction applications (concrete, brick, granulates of expanded clay, etc.). In order to
pursue the valorisation and dissemination of the acquired
knowledge, the Institute is also active within the European
interreg project ‘CEAMAS’ (www.ceamas.eu). French, Irish,
Dutch and Belgian partners are collaborating in order to
compile a list of the applications of marine sediments in
construction.

Environmental impact, one of the three themes of sustainable construction, focuses on the societal, economic and
ecological aspects. In 2013, the BBRI continued to follow
the developments of sustainable construction with a view
to ensuring, on the basis of its technical knowledge, a greater coherence between the ongoing initiatives in the area of
evaluating the sustainability of construction elements and
buildings. Within this framework, particular attention was
paid to the technical and scientific principles of sustainable construction that may be applied (and supported) on
the worksites of today – and those of tomorrow.

Comfort, Health, Accessibility and Safety
Our buildings are supposed to be comfortable,
healthy and safe. However, what is understood
by these concepts is ever-evolving: what is
deemed to be comfortable today may no longer be so tomorrow or the day after that. Recent
advances in the field of electronics, home automation and ICT are at the basis of numerous
new requirements in this area. Moreover, the
latest developments in terms of lighting have
lead to an increase in expectations.
In this context, safety, accessibility and adaptability play
an essential role. The acoustical aspect also constitutes a
significant criterion. Buildings or dwellings must protect
their users or occupants from outside noises (or noises
coming from the neighbours). On the other hand, the occupants want to be able to hear their own music or the sound
of their video games with great intensity, while others need
peace and quiet, do not want to be disturbed by resonance
phenomena, etc.
The evolution towards energy neutrality creates new
challenges in all of the above-mentioned areas, for both
new structures and renovations. These issues are further
emphasized by the problem of population growth and
ageing and, consequently, by the necessity of expanding
cities and designing new forms of housing and assistance.
In 2013, the BBRI played an important role in these themes
through various actions and studies which are detailed
below.
The nearly zero-energy consumption
of buildings is one of today’s key
preoccupations. For example, ‘nearly
zero-energy’ buildings constitute,
through the European and national
Energy
construction
regulations, an avowed objective
for which firm deadlines have been
established. However, the European directive (better
known under the name EPBD-Recast) emphasises that this
development may not under any circumstances negatively
influence indoor climate (due to a lack of ventilation, for
example).
1
In other words, it is imperative to pay sufficient attention
to aspects such as visual and thermal comfort, acoustical
protection and health (indoor air quality, presence of pollutants, etc.) in the search for technological solutions that
meet the energy challenges.
12
The VIS project ‘DO-IT Houtbouw – Duurzame innovatie
op het vlak van technologie en leefcomfort voor houttoepassingen in de bouw’ addresses these aspects in great
detail and is aimed at improving the performances of the
various wooden building systems so that they can be used
to construct buildings with nearly zero-energy consumption
in the future. To do this, it is primarily necessary to develop
integrated and validated solutions for the building’s envelope, stability, fire safety, acoustical protection and indoor
air quality as well as summer comfort. The objectives of this
project, which was launched in 2012 and which spreads over
four years, are detailed on the site www.do-it.houtbouw.be.
Within this context, the BBRI is responsible for missions relating to the hygrothermal quality of the building’s envelope, fire resistance, acoustical protection and indoor air
quality.
With regard to indoor air quality, this project focuses on the
potential impact of the used construction materials. Many
materials emission tests were therefore performed during
the year 2013. On-site measurements will be carried out
later so as to evaluate the proposed air quality models.
Obviously, there is good reason for this: besides the paints
and adhesives sector, the wood sector is one of the first

branches of the industry for which schemes for evaluating
the emissions of the used products have been elaborated.
The CEN TC 351 focuses on the development of a general
evaluation scheme allowing to comply with the requirements of the Construction Products Regulation.
Emissions from construction materials are obviously not
the sole sources of indoor environmental pollution. Within
this context, human beings play an important role, if only
by their presence and activities. Many other sources exist:
presence of plants, use of certain consumer goods and
devices, domestic animals, ... It is clear that these factors
can have a negative impact on comfort and even, in some
cases, on health in general. Moreover, in classrooms and
offices, they can constitute an important factor disrupting
the concentration and productivity of students and employees. Maintaining a high-quality ventilation is therefore
a must.
The BBRI has been focusing on problems regarding ventilation for several years now. In 2013, these works led to
the successful finalisation of the collective research project ‘OPTIVENT’ centred on developing guidelines and calculation tools for the optimal design and proper installation of ventilation systems in housing units. These tools are
available on the site of the project (www.optivent.be). They
notably include:
• a general introductory video on housing ventilation. This
film is mainly intended for installers, but can also be used
to encourage communication between the designer and
the installer with regard to the basic requirements of the
ventilation system
• a calculation tool for the installer specialised in ventilation
systems which makes it possible to support the design and
installation of his ventilation system. This tool can, for
example, be used for calculating the required minimum
flows, dimensioning conduits, calculating the pressure
losses, adjusting the flow, preparing the measurement
report for the acceptance of the works, ...
• a practical guide for the design, installation, commissioning and maintenance of ventilation systems. This document also addresses the needs of the installer specialised
in ventilation systems and includes practical, simple and
concise recommendations which are classified chronologically according to the entire installation process (design,
installation, commissioning, maintenance)
• a series of annexes organised by theme and containing
useful reminders. For example, the site includes an annex
on the acoustical aspects of the mechanical individual
ventilation of housing units (which clearly establishes a link
between the themes of health and acoustical protection)
and an annex on hygiene, pollution and maintenance
(which refers to the importance of maintenance as a means
of preventing the ventilation system from becoming a
source of pollution itself).
Proper installation of the ventilation systems in dwellings was at the centre of
the collective research project ‘OPTIVENT’.
Public authorities too are now paying greater attention to
the theme of ventilation. There is an increasing awareness
that good ventilation is essential to ensure a comfortable
and healthy indoor climate in current and future buildings
that are extensively insulated and airtight or that have a low
(or nearly zero-) energy consumption.
In 2013 for example, within the framework of the ‘Kwali-vent’
project, conducted at the request of the Flemish administration responsible for energy (VEA), a consortium coordinated by the BBRI surveyed the Belgian construction sector
looking for a support base for the introduction of quality
requirements in the field of ventilation. The Flemish Action
Plan ‘BEN-gebouwen’ devotes special attention to the quality of ventilation systems. The contribution of the main
stakeholders should enable this study to issue concrete
recommendations for future ventilation policy.
Two experimental houses were built
during the first biennial of the ‘DO-IT
Houtbouw’ project. A long-term hygrothermal testing programme for
various compositions of walls and

results as of 2014 (see the ‘Building Materials and Systems’

Due to its lightness, a wooden structure represents a
significant acoustical challenge in the construction of
semi-detached dwellings or apartments. Indeed, the
wooden structures traditionally created for single-family
dwellings present mediocre insulation performances with
respect to low frequencies (below 100 Hz) emitted, for
example, by television sets or music installations. The
low-frequency footstep noises produced by neighbours
also propagate easily.
Based on the know-how acquired during the project
‘AH+ – Optimalisation acoustique de la construction à
ossature en bois’ (‘AH+ – Acoustical optimisation of the
wood-frame structure’, finalised project), new studies
made it possible to considerably improve the airborne and
impact noises insulation of light wooden structures in the
low-frequency range. These new construction concepts,
which sometimes show better performances than certain
very heavy structures, are generally composed of an
innovative semi-detached structure of wall and floor whose
constructional nodes were designed with the greatest care.
Moreover, these solutions (floor, facade elements) are not
necessarily more expensive than traditional concepts. The
next stage of this project will focus on performances such
as fire resistance, stability and airtightness.
The thorough energy renovation of
buildings constitutes a considerable
challenge in view of future energy
and climate targets (2030 and 2050).
With regard to reducing greenEnergy
renovation
house gases emissions and energy
consumption, a more radical, faster
and higher-quality energy renovation is an absolute must.
Another major objective of energy renovation is naturally to
obtain greater comfort. Indeed, during such a renovation
project, the earlier building is transformed in such a way
that it can meet current comfort requirements.

Launched in 2013, the ‘RENOFASE’ project is intended to
support contractors, suppliers of materials and producers
in implementing effective and high-quality renovation
projects. This requires three main tasks: establishment and
dissemination of information, testing and validation of new
products, materials and systems and, finally, implementation through case studies.
The ‘STAR Sustainable Thermal Acoustic Retrofit’ project –
carried out in collaboration with the ‘Passive House’ Platform, the Building Research Establishment (Scotland) and
Lund University (Sweden) – is designed to develop an optimised multidisciplinary approach to renovations. It must
be acknowledged that, in practice, renovation generally
involves only a single technical discipline (thermal insulaInnovation which is often at the origin of problems
tion, for example),
regarding acoustics, fire safety, airtightness, etc. Integrating
all technical aspects within a single detail is a particularly
complex exercise for contractors or architects. The ‘STAR’
project focuses not only on the elaboration of a large series
of technical details incorporating the performances of the
various technical fields, but also on the creation of check-

lists for the designer and the implementer. For example, a
large number of ‘4D’ details and renovation concepts were
developed in 2013, in collaboration with different working
groups composed of manufacturers, consultancy offices,
contractors and experts, whether or not members of the
BBRI. These are 3D representations of the various constructional nodes, supplemented by their evolution during
the renovation works. The project ‘COST Action TU0901 –
Integrating and Harmonizing Sound Insulation Aspects in
Sustainable Urban Housing Constructions’ also allows the
BBRI to coordinate an international action working out such
details.
In 2013, via the Flemish Innovation Construction Platform
(Vlaams Innovatie Bouwplatform), the BBRI also actively
contributed to the issue of the calls launched within the
framework of the test bench ‘Woningrenovatie: innovatie
bij energiezuinig verbouwen’; the objective is to stimulate
the concept of renovation which can be reproduced on a
larger scale and thus to reach an affordable solution for
many existing buildings.
The call for projects ‘Bâtiments exemplaires Wallonie’ (see
p. 6) launched in 2012 gathered 72 candidacies, from which
23 were ultimately selected (17 new construction projects
and 6 renovations). In 2013, a new call was issued with a
series of broader criteria (energy performances, comfort,
control of consumption, choice of sustainable materials,
sustainable water management, soft mobility, biodiversity,
ecological worksites, waste management, urban and rural
expansion, architectural quality, accessibility and adaptability to persons with reduced mobility, flexibility, distribution of goods and services, profitability, reproducibility and
innovation). The final selection is scheduled for 2014.

The objective of the Flemish Network for Accessible Construction (Vlaams Netwerk Toegankelijk Bouwen or VNTB)
is to bring into contact the various actors of the construction process and to better inform them about the themes
of accessibility and adaptable construction. The regional
regulation on the accessibility of public buildings recently
entered into force and, given the ageing of the population,
the adaptability of private buildings and dwellings is becoming a worrying issue. For example, a specific workshop
was, organised on the occasion of the ‘Universal Design’
congress held in Flanders in March 2013. It was devoted
to the theme
‘Toegankelijkheid en Universal Design, één
Innovation
van de vele uitdagingen voor bouwheer, ontwerper en
uitvoerder’ (Accessibility and Universal Design, one of the
many challenges for owners, designers and implementers).
Moreover, intensive work was done in order to draft a Technical Report on accessibility which is aimed at inventorying
the consequences of accessible implementation on sanitary installations, joineries and flooring.
In the Walloon Region, the dissemination of information
concerning the construction of sustainable evolving housing takes place through the ‘Construire adaptable’ (Adaptable building) action (www.construire-adaptable.be). This
action is intended to encourage building professionals to
build more dwellings that can respond to the ageing of
the population or to the needs of persons with reduced
mobility, and this primarily by offering training courses and
by furnishing technical assistance during the design and
implementation phases. Finally, within the framework of
this project, a charter was drafted which can be signed on
a voluntary basis and which summarises the criteria that
an adaptable dwelling must fulfil. In the Brussels-Capital
Region, the theme of accessible and adaptable construction and renovation is extensively addressed within the
Technological Advisory Service ‘Eco-construction et développement durable’.
The Standards Antennas (www.normes.be) also have an
important role to play within the context of the dissemination of information. For example, the themes of comfort and
health are often covered in the SA ‘Energie et climat intérieur’ (‘Energy and indoor climate’). Safety is at the centre of
the SA ‘Eléments de façade manuels et motorisés’ (‘Manual
and motorised facade elements’), the proper functioning
of whose activities is assured by the BBRI in collaboration
with SIRRIS. One of the purposes of this Standards Antenna
is to inform the sector on the CE marking of shutters and
shading devices, notably through the elaboration of a specific guide to be published in 2014. Moreover, it accords
great importance to the fight against breaking and entering
through facade elements. Developed in 2013, a reference
system makes it possible to determine the required performances for burglary-impeding facade elements depending on the protection level envisaged for the building. The
SA ‘Acoustique’ (‘Acoustics’) guides the SMEs through the
maze of acoustical standardisation. Finally, fire safety is the
field of action of the SA ‘Prévention au feu’ (‘Fire Prevention’). The latter focused on the application of the section of
the Royal Decree relating to the fire safety of feedthroughs
in walls.
Nearly 110 training courses were given in 2013 on the theme
of ‘Comfort, health, accessibility and safety’. Fire safety was
given particular emphasis. Besides general information
sessions addressing the fire safety of buildings, training
courses specifically devoted to the processing of feedthroughs in walls were organised, notably in collaboration with the Association professionnelle des entreprises
Kwaliteitskaderde parachèvement (Professional association of finishing
contractors or BEWAP). They brought together no fewer
than 300 companies. The theme of ventilation has not been
left out either, since over 20 training courses dedicated
exclusively to this theme were provided.

With regard to publications, the end of 2013 was marked
by the publication of the TIN 249 on the execution of painting works. This document is much more than an update of
TIN 159. It describes not only the preparatory works required
to obtain the desired finishing level for different types of
supports, but also pays great attention to the new paints,
including those that supposedly have ‘low emissions of
volatile organic compounds’. The new Dossiers du CSTC
include the evaluation of paint/mastic compatibilities, the
implementation of glass guardrails, acoustical aspects relating to mechanical ventilation, adhesives for textile floor
coverings, vibration problems in structures, shop window
stiffeners, …
A prenormative study on the theme of building guardrails was launched in 2013.

Quality
framework
As the number of selection criteria
for exemplary buildings of the abovementioned ‘BATEX RW’ project attests,
the BBRI contributes in many ways to
the creation of a quality framework in
the area of comfort, health, accessibility and safety.
For example, in recent years the Institute has played an
active role in the realisation of various reference systems
for the evaluation of sustainable construction. Interregional
negotiations were mainly conducted in order to obtain a
common basis for the three Regions of Belgium.
The prenormative research conducted within the BBRI also
contributes to the drafting of various construction-related
standards. For example, a study was launched in 2013
on the theme of building guardrails. In 2010, a Belgian
standard (NBN B 03-004) was published in this area, but
it showed certain inaccuracies and shortcomings, and
has been the subject of numerous comments from the
professionals involved since its publication. It was thus
imperative to revise the document. The objectives of the
above-mentioned research programme are the following:
• to establish a method and criteria for the evaluation of
guardrails in order to guarantee personal safety
• to lay down prescriptions with regard to fixation of guardrails and in particular of glass guardrails
• to formulate guidelines for the implementation.
In the area of ventilation, the creation of STS’s continued
in 2013. The BBRI staff have also maintained various
contacts with the UBAtc.

With regard to acoustics, the prenormative project ‘RaDS –
Robust Acoustic Details Standard’ is designed to establish
calculation models for evaluating airborne, impact and
external noises insulation for typically Belgian structures.
These models should be incorporated as a national annex
into the acoustics Eurocodes of the NBN EN 12354 series. A
survey was also conducted on robust construction concepts
and constructional nodes, in which the calculation models
can be applied for extrapolation purposes. Inspired by the
English ‘Robust Details’ approach, this project made it possible to establish that a good monitoring of the quality of
robust details clearly leads to less construction damage
and to less expensive buildings. The knowledge acquired
during the various prenormative research projects of the
‘Acoustics’ division may, ultimately, be used for the development of Belgian acoustics standards specific to schools
and other non-residential buildings (offices, hospitals,
Cadre
hotels, cafés,
restaurants, etc.).

It follows from the foregoing that
the regulations on rational energy
use and acoustics are at the origin
of many evolutions and innovations
in the building sector. For example,
the new acoustical standards led to
Innovation
a sharp improvement in acoustical
protection and to the development of a substantial number
of new products, concepts and better-adapted details.
6
Due to the ageing of the population, it is increasingly widely
recognised that innovative and sustainable solutions are
also needed in the field of accessibility and adaptability.
This emerges clearly from the works of the ‘Constructive
Details’ Working Group of the BBRI. All the constructive
details elaborated within this framework must comply with
the basic requirements in terms of energy, air- and watertightness and acoustical insulation as well as with the principles of accessibility.
Accessibility and adaptability represent the social
dimension of sustainable construction. These topics will
only gain in importance in the future, given the increasing
ageing of the population, the steadily rising costs of health
care and the decentralisation of hospital care towards
infrastructures outside the hospital. For most people, the
word ‘accessibility’ is synonymous with ‘wheelchair accessibility’. However, the problem of accessible construction
is much broader than that, since the elderly do not live or
move about only in wheelchairs. In this context, the use of
light and colour is equally important. These contribute not
only to visual comfort, but can also play an important role in
safety, accessibility and the legibility of the built framework
(formation of obstacles, creation of proper signals allowing
effective orientation and circulation inside the building).
Moreover, the international ISO 21542 standard confirms
the importance of a good contrast of tones.
The themes of contrast, light and colour are extensively
addressed within the framework of the VIS project ‘Groen
Licht Vlaanderen 2020’, whose work is spread over six years.
The method for evaluating contrast used in this context is
based on a difference of reflection coefficient (LRV) between
the surfaces studied. In 2013, standard situations in which
the aspects of contrast and light have a significant part to
play were inventoried and evaluated in order to determine
whether specific requirements should be applied. The
signalling of evacuation routes offers a good illustration of
this. A simple tool making it possible to help the designer
choosing the right colour and contrast according to the
desired use is also in development. In other words, the
requirements in the field of the coefficient of reflection must
correspond to a system of colour codes such as RAL or NCS.
However, this is only the first step, because it still does not
take the characteristics of the lighting installation itself into
account. In this context, a test mechanism was developed
at the UZ Brussel with the objective of determining the
impact of dynamic lighting on the process of wayfinding
in a complex environment, i.e. to favour the possibility of
finding one’s way by using adapted signalling and lighting.
Innovation can also manifest itself outside the sector.
The VIS project ‘Omkaderd thuiswonen’ on which the
BBRI actively collaborated in 2013 is a good example: this
project develops solutions to satisfy the (future) needs
of elderly people who wish to live autonomously at home
for a longer time. A series of workshops and events firstly
made it possible to determine the ‘key priority challenges’:
autonomy and prevention, integrated care, dwelling,
neighbourhood watch, ... In the light of these challenges, a
concrete follow-up trajectory will be established, on which
various actors from the health care sector, producers,
installers and construction partners can collaborate;
the objective being to obtain innovative concepts and
technological solutions in the domestic environment.
The themes of contrast, light and
colour are addressed in detail within
the context of the VIS project ‘Groen
Licht Vlaanderen 2020’, whose work is
spread over six years.
Building Materials and Systems
The construction sector is constantly on the
move. Materials and execution techniques
are developing rapidly in order to create
new building possibilities. This development goes on at three levels: economic to
increase competitiveness, environmental to
stimulate the use of sustainable materials,
and social so as to improve safety.
With nearly 16 million cubic meters
used each year, concrete remains an
emblematic construction material.
In 2013 the BBRI strove to study its
various facets from the perspective
Energy

of sustainable construction through
a series of actions. Those include the
projects linked to sustainable development, and among
others ‘CemCalc’, whose objective is to develop new ternary
cements with a high limestone content. The first biennial
of this research generated encouraging results in terms of
both mechanical strength and sustainability performances
of the low slag-content cements-made concretes containing up to 25% limestone. This study will then focus on ternary cements with high limestone content and low fly ash
content. As regards durability, the effects of freeze/thaw
cycles on various compositions of concrete with or without
air-entraining agent were also studied, according to the
type of curing and by means of different test methods.

Like any building system, a wooden construction project
must be carefully thought out, all the more so if it involves
the construction of average-height buildings entailing a
series of challenges that must be faced: edifice stability,
fire safety, acoustics, thermal comfort, ... The sector is waiting for technical details on the constructional nodes that
Building systems are also evolving. Wood-frame structures
are undergoing an unprecedented development. This
building method attracts both professionals and private
individuals for many reasons, including the construction
of energy-neutral and sustainable buildings. This trend
justifies the BBRI’s growing involvement through various
research programmes aimed at evaluating the durability of
such structures. The materials (type of insulation, nature
of the air and water vapour barrier, etc.) must be carefully
chosen and the implementation must be meticulous in order to ensure the structure’s durability and performances.
The ‘OPTIDUBO’ research is seeking to optimise the composition as well as the implementation and use conditions
of wooden building systems (among others ‘compact roofs’
and ‘perspiring walls’) so as to guarantee their initial performances and their biological durability over time. Various

aimed at evaluating the strength and rigidity of wooden
floor diaphragms when these are subject to cyclical horizontal stresses. In the light of the test campaign on floor
diaphragms and junctions conducted in 2013, analytical
and digital models allowing to predict the performances
of the interconnected structural elements were developed.
In the area of wooden structure stability, the BBRI also
continued its research relating to the development of an
insulating structural wooden building panel made of indigenous tree species (‘STABILAME’ project).
In addition, the BBRI is participating in the VIS research
‘DO-IT Houtbouw’. This multidisciplinary research also
strives to make available to the sector technical details that
are optimised with regard to all the requirements for multistorey wooden structures: acoustics, fire safety, stability,
hygrothermal performances, airtightness, air quality, …
In 2013, substantial progress was made in the field of the
acoustics of multi-storey wooden structures with the support of the BBRI: wooden floors and walls with remarkable
acoustical performances were developed within the framework of this research project.

renovation
Amongst the various methods for the
energy renovation of facades, the renderings on external insulation (ETICS
with rendering – External Thermal Insulation Composite Systems with Rendering) continue to be the subject of
special attention from the BBRI. Apart
from the systems of renderings on external insulation, there
is currently a growing interest in the use of different types
of hard coatings glued on site onto insulation (terracotta
bricks, ceramic tiles, natural stone or agglomerated stone).
The BBRI’s research actions regar-ding these building techniques further intensified in 2013, among others through
a study relating to innovative systems (‘Innov-ETICS’ research in the Brussels-Capital Region), a technology transfer action ‘Gevisol-ETICS’ and the prenormative research
‘VETURES’. The latter concerns the glueing of hard finishings on an insulating material for the external thermal insulation of walls. Thanks to laboratory experiments and
digital simulations performed in 2013, those systems were
studied in order to overcome the evident lack of standards
and to enable this technique to be fully developed.
While the thermal insulation of facades is essential to the
energy renovation of existing buildings, it is also important to propose joined elements (windows) with improved
energy performance. Increasing the thermal performances
of joineries can, in certain cases, entail a reduction of the
other essential performances that the joineries also need
to fulfil. Moreover, it is necessary to guarantee all its performances over the years in order to support a sustainable
renovation policy. These aspects are currently undervalued
in the development of new products. The ‘DuraPerf’ research, financed by the Walloon Region, deals with the
durability of the performances of more energy-efficient
joined elements. It should make it possible to respond
to these concerns by establishing good practice rules for
designing and implementing joineries so as to ensure the
durability of their essential performances. Finally, the connection of joined elements to the rough structure must
not be underestimated. The sector is awaiting technical
details which are optimised for all the requirements (airand watertightness, acoustical insulation, etc.) applying

subject. Projects about concrete include ‘Betonic@’ (www.betonica.be),
whose goal is to disseminate digital information on concrete by means of e-learning modules, webinars and a

In recent years, the BBRI staff has been confronted
with many cases of delamination of the upper layers of
industrial floors. The Institute focused on the problem
at the behest of the ‘Rough Structure and General
Contractors’ Technical Committee as well as of the
Fédération des polisseurs (Federation of Polishers). The
‘FLOORCRETE’ research highlighted the fact that some additives, under certain conditions, can cause air entrainment
in the concrete and increase the risk of delamination of the
upper layer. These results, in conjunction with recommendations on the implementation, are currently being integrated into the TIN 204 revision project. They were also the
subject of an article published in 2013.
The problem of the aesthetic aspect of concrete is also a
point which requires the BBRI’s attention, since the demand
for exposed concrete is growing. This has consequences for
the acceptance of works, and so it was crucial to establish
specific recommendations on the subject (which are currently being drafted in a TIN). Nevertheless, some points
remained problematic, which is the reason why the study
‘Zicht- en sierbeton: Uitvoeringseisen en evaluatieprocedures’ was initiated. The main objective of this project is to
contribute to the development of normative documents on
the subject through four specific strands of research:
• requirements for concrete and formwork
• reliable analysis techniques
• establishment of evaluation criteria
• application of statistical analysis to the measurement
results.
The results of the study are expected for 2015. This issue is
not specific to concrete, since another research project ‘Uitzicht van afwerkingsmaterialen’ is aimed at harmonising
methods for evaluating the aesthetic character (among
others tone) of finishing materials. However, this project is
distinguished by its approach based primarily on psychovisual tests. The first results of the study were presented
during a seminar on the subject.
The publication of the TIN 243 devoted to facade coverings
made of wood and wood-based panels (NIT 243 ‘Les revêtements de façade en bois et en panneaux à base de bois’,
available since the start of 2012) inaugurated a series of
initiatives in terms of information and training highlighting
wooden construction throughout the year 2013: the special
‘La construction en bois’ issue of CSTC-Contact (2013/1)
thus pointed out how much the performances of these
building systems have progressed in order to meet the mul-
tiple requirements imposed on current structures. Other
accomplishments include the finalisation of the STS 23
‘Construction à ossature en bois’ (‘Wood-frame construction’), the winter courses (from January to April 2013), and
the ‘Innov’action bois’ conference dedicated to wooden
collective buildings and organised within the framework of
the Technological Advisory Service ‘CDUBOIS’.
Finally, the Standards Antennas (SA) of the BBRI are still
doing a great deal of work to inform SME’s from the sector
about the normative evolutions on the Belgian and European levels. Based on their experience, the action of the
SA’s sometimes also entails the development of innovative
products.

framework
this context, in 2013 the aforementioned ‘OPTIDUBO’ research notably focused on working
out a test method for the determination of the resistance
of natural insulations to biological agents. The ‘DURISOBO’
and ‘DEFISOL’ studies also fall within this framework. There
are many types of thermal insulation, applied on different
parts of the building, which play not only a filling role, but
are also subject to stresses (variable loads on floors, solar
panels and vehicles on roofs, wind and vibrations in vertical walls, etc.). These studies, prompted by the lack of criteria for performances other than the thermal performances
of insulations (mechanical strength, durability, etc.), seek
to establish a quality framework by identifying and quantifying these stresses according to the application. They
are also striving to determine the admissible deformations
depending on the targeted applications. Within this framework, the TETRA ‘Sols intérieurs isolés’ (‘Insulated indoor
floors’) project, in which the BBRI is participating, supplements these studies as regards the more specific applicaCadre

refractory concrete. The most notable result of this project
is the development, by the BBRI, of a multiscale approach
to formulation. This makes it possible, from a limited number of tests, to rapidly adjust the rheological behaviour of a
refractory concrete so as to adapt it to the implementation
method (vibration, spraying, self-compacting character).
While great attention is still devoted to execution techniques (notably with regard to the traditional support techniques, for which a certain number of execution sheets were
created thanks to what was learned from a prenormative
study), new infrastructure technique concepts are being
developed, among others through the ‘SOIL MIX’ project.
This project is intended to provide a remedy to the collective shortcomings concerning soil mix material: mechanical characteristics, permeability, collaboration between the
metal profile and the soil mix and durability. In association
with the sector (ABEF) and the KUL, a substantial research
programme generated a large collection of data used to define recommendations for the application of the technique.
Besides the traditional materials, new possibilities
emerge in the construction sector, including those linked
to the composite materials illustrated by the ‘Generation
Composite’ project. For example, a portfolio was created
within the context of evaluating their potential, so as to
present the experiences acquired at the national and international levels with this type of material. A working group
was specifically organised in order to study the advantages
and drawbacks of these applications.

through various actions such as the

Support technique (‘SOIL MIX’ project).
Technical Installations
Human beings construct buildings so as
to be able to live, work, teach, care, relax
in them ... under optimal conditions. They
also yearn for a good indoor climate that is
perfectly adapted to their needs with regard
to warmth, coolness, air quality, light and
tranquillity, while respecting energy and
environmental constraints.
A low-energy building which is well-insulated and airtight
and which enjoys sufficient natural light requires technical installations that fulfil a number of additional requirements.
• design and dimensioning of a network of equilibrated
conduits (calculation of the load losses)
• regulation of the different outlets
• EPB reporting.
However, those installations are not aimed at resolving
the errors due to a poor design or an inadequate implementation of the building. On the contrary, they should be
regarded as a part of the overall concept.
A calculation tool which develops these different stages
was also created and it has already helped the installers
greatly. This project also addresses other aspects relating
to ventilation such as air quality for example (see p. 13).
In buildings with a very limited energy
demand, the installations for heating,
cooling, ventilation, lighting and hot
water must be able to satisfy variable
needs easily. Thus it is not surprising
Energy
construction
to find that the technical equipment
in nearly zero-energy buildings gain
in complexity and constraint.
In our very low-energy buildings, the hot water system
constitutes one of the main sources of energy consumption. The objective of the Tetra project ‘Eau chaude sanitaire’ (‘Sanitary hot water’) is to get a better view of the real
peak demand for sanitary hot water. For this purpose, the
BBRI is currently performing a series of on-site measurements. These peak flows are largely overestimated in the
calculation rules and draft standards, often leading to a
substantial overdimensioning of the installation.
1
The ‘SMART-GEOTHERM’ project (www.smartgeotherm.be)
is a future-looking study that focuses on the various possibilities for using geothermics in order to heat premises.
In this context, the BBRI conducted, amongst other things,
a study on the retention of heat and cold in the building’s
structure, on the implementation of heat pumps, and on
the advanced management of heat supply and demand, for
an optimal distribution by means of the buildings’ installations.
A very important study bearing on the implementation of
ventilation systems in dwellings was conducted within the
context of the ‘OPTIVENT’ project (see p. 13). It was found
that the world of practice has a need for good guidelines
which can help create high-performance and comfortable
installations. This project is developing the various stages
of the assistance plan for the realisation of the installers’
projects. The plan will deal in turn with the following aspects:
• choice of the ventilation system
• determination of the flows
22
A better understanding of the demand for hot water will
enable a better dimensioning of the installations, without
any loss of comfort. The rational use of drinking water is
another aspect which is growing increasingly important.
A Technical Information Note is being prepared on the
subject; its purpose is to assist installers with the design
and the installation of rainwater use systems in buildings.
An overestimation of peak flows in the calculation rules and draft standards often
leads to a substantial overdimensioning of the installation.
Technical Installations
There is still a great deal of room for optimisation and
innovation in the area of lighting: it is for example possible to use natural lighting and to apply advanced lighting systems with low energy consumption and smart
control, for example. Indeed, with the appearance of LED
(light emitting diodes) technology, the world of lighting
is undergoing a genuine revolution. This is taking place
very rapidly and is currently extending to functional applications for interior lighting. The ‘Groen Licht Vlaanderen
2020’ project (www.groenlichtvlaanderen.be) addresses
the various aspects of this issue (see p. 17). The ‘AIE 50’
project (Advanced Lighting Solutions for Retrofitting
Buildings) strives to identify synergies on the international level.
During the installation of technical
systems, it is necessary to take
adequate account of the current
requirements that apply to the
envelope of the building. It is selfTechnical
evident that badly conceived condetails
duit feedthroughs or poorly fastened
systems (solar panels and so on) may not under any circumstances impede the finishing of the technical details or
entail a loss of performance (watertightness, air and vapour
impermeability, and noise insulation).

The adaptation of the existing buildings to new requirements implies not
only focusing on the renovation of the
envelope, but also considering highperformance and adapted heating,

ventilation and lighting installations.
The ‘RENOFASE’ project is aimed at
finding solutions which can be integrated into the building’s envelope. For example, it is not at all easy to conceal ventilation ducts in existing buildings. A solution to
this problem is to place them on the outside of the facade

and the Bouwunie, in which more than 450 installers took
part. Generally, nearly 50 training courses about technical
installations were provided in 2013.
Several articles were also published: ‘Chauffer et refroidir
grâce à la géothermie’ (‘Heating and cooling with geothermics’), ‘Le dimensionnement des ouvertures d’évacuation

(‘The centralised production of sanitary hot water in apartment buildings’), ‘Les conduits de fumée collectifs à tirage

Within the framework of the ‘Kwalivent’ project, the BBRI conducted a
study in order to determine to what
extent the Belgian building sector
supports a high-quality approach in

the field of ventilation. STS’s on venframework
tilation were also written in association with the BCCA. With regard to the sector of renewable
energy systems (thermal and photovoltaic solar installations, heat pumps, ventilation with heat reco-very, etc.),
various quality procedures were drafted with a view to the
labellisation of installation companies, and a system of
certification for installers (after training and examination)
was introduced. The BBRI is working on this in collaboration

The BBRI actively supports companies which develop innovative solutions.
For example, the Institute is closely
involved in the development of a new
floor heating system that is much
lighter than the usual systems. Composed of grooved
wooden panels and metal clips, it can be easily installed
on an existing floor as part of a building renovation.

The BBRI supported the sector by assisting it in determining
the characteristic curves of the system, in compliance with
the new floor heating standards.

Technical and Organisational Assistance
The personalised advice offered by the ‘Technical Advice and Consultancy’ department
as well as by the ‘Management’ division to
construction professionals and companies
constitutes one of the strengths of the BBRI.
The Institute is actively involved in the field,
which enables it to give the best support to
the sector through technical and/or organisational assistance.
Technical Assistance
There is no getting around it: modern buildings have to meet
a growing number of performance requirements aimed
at guaranteeing the comfort of their occupants. These
requirements concern not only the stability, durability and
watertightness of the structure, but also aspects such as
its thermal and sound insulation, airtightness, fire safety
and accessibility. Since these requirements are becoming
increasingly strict, it is vital that companies be as flexible
as possible in order to be able to take these changes into
account.
The performances to be reached are described in various
regulations and standards (EPB regulation, basic fire prevention standards, etc.) and often depend on parameters
that are specific to each project (ambient noise near railway
lines or airports, etc.), the intended use and the owner’s
wishes. The result of all this is a multiplication of new materials and techniques on the market, each of them requiring
appropriate implementation. For more information on the
subject, the professionals can usually consult the technical
documentation of the products concerned, the specifications and the BBRI’s publications.
However, these actors sometimes need more personalised
assistance. The construction process has been the subject
of such a plethora of publications that even the best search
engines do not always come up with the desired information. In addition, since certain answers are not conclusive,
it is sometimes necessary to compare several documents,
with all the interpretation problems that this entails. Moreover, high-performance buildings can bring challenges for
which no standardised approach is currently available and
which require a specific answer. This is precisely the task
of the BBRI’s ‘Technical Advice and Consultancy’ department (TAC), which is available to help the professionals.
24
The engineers of the ‘Technical advice’ division (ATA)
handled no fewer than 13,000 questions by telephone and
received nearly 10,000 e-mails. Moreover, some 900 cases
required on-site visits in order to make findings and/or to
perform tests on the spot. During these oral and written
contacts, the engineers strive not only to provide the professionals with the right information as quickly as possible,
but also to improve their knowledge so as to increase the
quality of the structures in their entirety and to enable the
sector to construct the requested high-performance buildings.
The questions posed are an important source of feedback.
They enable us to identify the recurrent problems that affect
the sector, but also the shortcomings that still characterise
the available information and techniques. So it goes without
saying that this information is used intensively in order
to improve the relevance of our actions. This mission is
entrusted to the ‘Interface and Consultancy’ division (ICO).
This working method permits the BBRI to publish articles
that match the users’ needs and to organise training
courses that respond to the specific demands of the sector.
Technical and Organisational Assistance
Moreover, the engineers of the ‘Technical Advice and Consultancy’ department are represented within various Technical Committees and working groups and participate in
many research projects: ‘Le Grand-Hornu’ renovation project, development of execution details within the framework of the constructional nodes issue, projects such as
‘FLOORCRETE’, ‘Betonic@’, ‘RENOFASE’, ‘Luchtdicht bouwen van A tot Z’, ‘Build Up Skills’ and so on.
Organisational assistance
At present, the growing number of performance requirements imposed on new structures and on existing buildings force contractors to pay constant attention to the
organisation and the profitability of their activities. Indeed,
a proper use of new materials and techniques often necessitates adapting the organisation and the coordination of
the works.
Since the demand for financially affordable housing is growing steadily, it is not surprising to see themes such as profitability or lean construction gain in importance. However,
a thorough optimisation of the entire construction process
is required in order to reduce construction costs. In 2013,
the engineers and economists of the ‘Management, Quality
and Information Technologies’ division (GEBE) studied this
issue by means of relevant research activities.
The BBRI also developed its expertise in calculating cost
prices, thanks to a focus on the financial analysis of construction companies. This should allow companies to
correctly interpret their annual figures (liquid assets, solvency, profitability and added value of certain projects) and
thus to make informed decisions about their management.
However, the financial analysis should not be limited to the
internal organisation, but can also be applied to other intervening parties (subcontractors, suppliers, customers, etc.).
Good communication between the company and the (certified) accountant therefore proves necessary.
The proper organisation of the company and the skills
of the employees are essential in order to deal successfully with the increasing complexity of building methods.
For example, within the context of the project ‘Luchtdicht
bouwen van A tot Z’, the BBRI strives to determine which
organisational tools can be made available to companies,
with a view to reduce the costs of non-quality and possibly
to prevent processing errors.
In the wake of the projects ‘ConstrucTic’ and ‘ABC DigiBouw’,
the GEBE division was contacted repeatedly by members
wondering how to computerise their company. The ques-
tions posed concerned not only the implementation of
the cost price and of planning calculation tools, but also
the very planning of the company’s resources (enterprise
resource planning or ERP).
In this context, the BBRI developed a number of learning
modules (Excel applications compatible with MS Office)
making it possible to move smoothly from theory to
practice. They can be downloaded free of charge from the
website www.cstc.be/go/cpro:
• the application C PRO© offers the possibility to calculate
the cost price and to establish price offers
• the application C DATA© makes it possible to evaluate the
average hourly wage, but also to determine the distribution
of the general costs and to estimate the costs of materials
• the application C FACT© is aimed at establishing progress
reports and drawing up invoices
• the application C DOC© simplifies the management of
documents
• the application C PREP©, finally, is intended to make
the preparation of a worksite easier thanks to a checklist
containing the various tasks that must be performed.
In 2013, the feedback from the SME’s using these applications was analysed in detail so as to allow us to further
improve these modules and thus to better satisfy the needs
of users.
Finally, our employees have individually accompanied
some sixty companies and organised nearly 200 training
courses touching on such flagship themes as cost price calculation, financial analysis of companies, planning of projects and resources (manpower, materials and equipment).
Associations of the BBRI
The BBRI participates in the works of numerous associations linked to construction
and it even contributed to the founding of
some of them. Dedicated to several specific
construction activities, these institutions
always give the priority to providing support
for companies.
Recywall
The mission of Recywall (www.recywall.be) is to help companies to valorise and to recycle their wastes. In 2013, the
close collaboration continued with the establishment of a
polycentric Technology Advisory Service of which the BBRI
is part.
Tradecowall
The objective of this company is to find solutions for the treatment of inert wastes and excavation soils coming from construction and demolition worksites (www.tradecowall.be).
The year 2013 was characterised by the reticence to accept
recycled granulates, even when they bear the CE2+ marking,
as well as by the lack of a well-defined regulatory framework
for excavated soils.
Belgian Construction Quality Society (BCQS)
BCQS (www.bcqs.be) trains and accompanies companies
with a view to create an effective system for the management
of quality, safety and the environment. Depending on its
needs, the company may apply for a ‘Construction Quality’
label or a certification (ISO 9001, ISO 14001 or VCA).
Belgian Construction Certification Association
(BCCA)
BCCA (www.bcca.be) is one of the Belgian leaders of certification in the construction sector and holds, thanks to this
status, an accreditation from the BELAC office. For several
years now, this non-profit organisation has been supporting the collective ‘Construction Quality’ label and has been
regularly performing production inspections within the
context of the CE marking.
Belgian Centre for Domotics and Immotics (BCDI)
The BCDI (www.bcdi.be) defines itself as a study and
information centre in the field of home automation and
building automation. Themes such as personal assistance, smart cities and intelligent buildings are also part
of the BCDI’s expertise. In recent years, this centre has
collaborated on many national and European research
26
projects as well as on various congresses, forums and
workshops.
CentrumDuurzaamBouwen (CeDuBo)
Thanks to the renewal of its exhibition and to the
organisation of various seminars and training courses,
CeDuBo (www.cedubo.be) remains the reference centre
for sustain-able construction for both building professionals and the gene-ral public. In addition, it coordinates the transition network Duwobo (www.duwobo.be)
and it participated in the creation of the Dubolimburg support platform (www.dubolimburg.be) and of
Duwolim (www.duwolim.be), one of the local entities established within the framework of the FRCE (www.frce.be).
Organisatie voor Duurzame Energie (ODEVlaanderen)
As a coordinating body for sustainable energy in Flanders
for more than 15 years, ODE (www.ode.be) ensures the
consultation between the companies and organisations
in the field of renewable energy and the public authorities
through thematic platforms: heat pumps, photovoltaics,
biomass, wind energy, ‘green’ electricity, ... The BBRI is
responsible for their integration in buildings.
Quality Centre for Sustainable Energy Technologies (QUEST)
QUEST (www.q4q.be) drafts, together with the construction
sector and Construction Quality, quality procedures and
technical reference documents for the application of small
renewable energy systems (heat pumps, thermal and
photovoltaic solar installations, ventilation systems with
heat recovery, etc.).
Vlaanderen Bouwt (VLABO)
VLABO (www.vlaanderenbouwt.be) sets up, with the technical support of the BBRI, construction projects to create
durable, high-quality housing for local authorities while
monitoring the urbanistic, architectural and technical
qualities of the design and its costs.
Technical Committees
The activities of the BBRI are oriented by thirteen Technical Committees. Eleven of them
directly represent a branch of the construction industry and are composed essentially
of contractors. The other Committees focus
on subjects of interest to several branches. In
order to guarantee this bottom-up approach,
each Committee defines the actions that
will be taken the following year, via working
plans submitted for approval to the Standing
Committee of the BBRI.

Personnel
In order to successfully fulfil its mission,
the BBRI bases itself on the expertise of
more than 230 staff members coming from
a wide range of disciplines. This combination of professional skills, commitment and
versatility helps to make the Institute the
authorised body that it has become within
its sector.
The BBRI strives to improve the quality in construction and
strengthen the skills of the professionals of the sector.
This task is far from being an easy one, considering the
fragmentation of the building process and the diversity of
the partners involved.
To accomplish its mission and anticipate technological
developments, the BBRI can rely on a dynamic and
multidisciplinary team. Our staff thus ensures that the
fruits of the scientific and technical research conducted
by the Institute benefit building contractors, but also other
professionals of the sector (architects, consultancy offices,
surveyors, education, administrations, etc.).
The experience and pragmatism of some staff members
combined with the innovative vision of others enable
the Institute to publish practical works, to provide
custom-tailored technical advice as well as to organise
courses and training sessions that meet the real needs of
the sector.
Given the growing complexity of those needs and the
increased interest in areas such as sustainable construction and renovation, finishing techniques, energy and
indoor climate, IT applications in construction as well as
the accessibility of buildings, the BBRI expanded its staff
numbers to a total of 237 employees in 2013.

One thus finds that the fees of the members represent
some 55% of the total revenues.

Destination of the expenditures
The diagram presented below shows the revenues and the
expenditures which result from the activities of the BBRI,
after distribution of the structural expenses. The latter
represent not only the costs relating to the buildings and
equipment, but also the administrative costs. This demonstrates that the totality of the available resources benefits,
directly or indirectly, the construction companies.

Indeed, if 89% of the total budget is directly invested for
the benefit of the sector, 11% of that is valorised in research
activities under contract which, in the long run, also benefit construction. Consequently, all of our resources are
devoted to improving the quality and the competitiveness
of the sector, which is ultimately the founding mission of
the Institute.

Research • Development • Information
Primarily financed by the membership fees of some 85,000 Belgian companies, representing virtually all of the construction trades, the BBRI has been considered for more than
50 years as one of the leading scientific and technical institutes, contributing directly to

Research and innovation
The introduction of innovative techniques is vital for the survival of an industry. Oriented
by the construction professionals, contractors and experts sitting in the Technical Committees, the Institute’s research activities are closely aligned to the day-to-day needs of the
sector.
With the aid of various official bodies, the BBRI encourages companies to continue innovating, offering advice that is tailored to the current social challenges and applicable to
various domains.
Development, standardisation, certification and approval
At the request of public or private players, the BBRI also works on various development
projects (contract research). Actively collaborating in the activities of the standardisation
institutes – on the national (NBN), European (CEN) and international (ISO) levels – as well
as in those of bodies such as the Belgian Union for Technical Approval in Construction
(UBAtc), the Institute is ideally placed to gain insight into the construction sector, so that
we can respond more quickly to the future needs of the various building trades.
Dissemination of knowledge and support to companies
The BBRI makes extensive use of information technology in order to efficiently share the
results of its work with all companies of the sector. Our website, adapted to the diverse
needs of construction professionals, contains the publications of the Institute as well as
more than 1,000 construction standards.
Nevertheless, personalised training and technical assistance remain essential for disseminating information and so, along with some 650 information sessions and thematic
lectures offered by BBRI engineers, more than 26,000 pieces of advice are issued by the
Technical Advice Division each year.
