The Netherlands: Twenty percent heritage buildings
< 2% listed monuments
buildings
18% traditional
80% modern buildings
Individual interests
Building:
•
Affordability
•
Economic value
•
Safety
•
Appearance
•
Comfort
•
…
Site:
•
Identity / amenity
•
Accessibility (by public
transport)
•
Social contacts
•
Safety
•
Tourism/economic value
•
…
Contradictions
Owners / users are afraid that energy
prices will rise again:
•
Doing nothing is not an option
•
Often they choose for 'standard'
measures: insulation, double glazing
Owners / users want more comfort and /
or more space:
•
Using the attic requires windows,
insulation, ...
A new function means new requirements:
•
Accessibility (elevator)
•
Safety (fire requirements)
•
Indoor climate (lighting, daylight,
temperature, humidity, ...)
Dutch Manual Sustainable Architectural Heritage
•
•
•
•
•
The manual was
published in 2008
The second
edition followed
in 2012
17 projects are
analyzed
20 strategies are
described
An assessment
tool is included
‘It will never be the same again!’
Expectations for the Dutch
situation:
•
The identity of the site
becomes more important.
•
Focus on existing buildings
•
From supply- to demanddriven market: What do the
owners / users want?
•
More cooperation between
professionals.
•
Collective initiatives by
private owners/users.
•
Technological developments
go much faster than before.
•
Sustainability remains an
important topic but has to
become demand-oriented, too.

Identity of the site becomes more important
Focus on exisiting buildings
•
•
•
We are faced with vacancies and shrinking regions.
The amount of new buildings is strongly reduced.
People appreciate buildings ‘with a story’ – many prefer historic or
characteristic buildings, but the possibilities for use/reuse depend on the
location
Context and customization
•
•
•
•
•
•
•
The context of the projects has a substantial
influence on the choice of measures and the
speed with which projects are realized.
The owner of a heritage building in the center
of Amsterdam could not sell it for an
acceptable price.
Several young companies now rent the
building, but for a lower rent than usual.
In return, they invest in sustainable measures.
After 5 years the building will use a minimum
of energy and will produce sustainable energy.
The companies will pay the usual rent then,
but the energy bill will be very low. So the
total costs will not increase.
On the other hand, the value of the building
will be increased.
Shifting responsibilies: From national to local level
•
•
•
•
•
•
Advisory role for the Minister of Education, Culture and Science (OCW)
became limited in 2009
Now the minister only gives her recommendations if a listed monument is
demolished, substantially altered, gets a new funct.ions or is reconstructed.
For all other interventions the municipalities are responsible
Dutch municipalities thus have the legal responsibiltiy to develop local
policies regarding their architectural heritage
The State Service for Cultural Heritage provides information (publications,
meetings) and even launched a 5 years programme for sustainable
architectural heritage management to support local governmental bodies.
The shift of responsibility also led to uncertainty: companies and owners of
heritage buildings wish more clarity.
Historic layers
•
•
Hilversum: ‘Most of our monuments are young. Only few interventions are
realized. We want to keep them intact.’
Utrecht: ‘We have many ancient monuments. Many interventions are
realized, layers are added. We can add a new layer but it has to fit to the
earlier interventions.’

Municipality of Hilversum: architect Dudok, young heritage buildings,
only few interventions
Municapality of Delft or Utrecht: historic center, many
interventions/layers are added, a new layer is acceptable

Archeological findings
•
•
•
•
•
•
At Paushuize in Utrecht
parts of the basements
were brought to a lower
level
During the renovation
archeological findings
from the Roman period
were discovered
These became integrated
in the design
The planning of the
renovation ran out
The costs rose
significantly
But the result is superb!

•
Municipality of Hilversum: no archeological findings expected,
interventions in the ground are acceptable
Municapality of Delft or Utrecht: archeological findings are expected,
interventions in the ground should be avoided

More Cooperation
•
•
•
One of the new features: more and more intensive
cooperation between stakeholders
The Center for Sustainability of Nyenrode
Business Universiteit facilitates networks for
different challenges: combining knowledge,
experience and creativity to develop creative and
smart solutions, which fit into the new context
Organisations pay for their participation in the
networks. As the costs are shared between all
participants, the costs are lower than for
individual research projects.
‘Network Sustainable Architectural Heritage
Manamgent for Governmental Bodies’
Combining knowledge in order to
find creative and smart solutions
• Municipality of Hilversum
• Municipality of Nijmegen
• Municipality of Den Haag
• Municipality of Utrecht
• Municipality of Delft
• Municipality of Haarlem
• Municipality of Arnhem
• Region of Drenthe
• State Agency for Cultural
Heritage
DuMo-network for governmental bodies: 5 topics
•
•
•
•
•
Topic 1: Share the available knowledge
Topic 2: Develop new knowledge
Topic 3: Learning meetings
Topic 4: Communication
Topic 5: Policy /changing role for
governmental bodies
Thema 3: Learning meetings – the example of the
Cathedral Choir School
•
•
Main question: Is it
possible to make better use
of the knowledge of
companies? Should we
work together in an earlier
projectphase and in
another way?
The case: Cathedral Choir
School in Utrecht
Topic 3: Learning meetings
Some of the reactions:
• The constructor: “Let me understand the building
well.”
• The architect: “That the municipality will check
afterwards is not of this time.”
• The owner: “I want to make an agreement with all the
organizations involved. In the agreements the
performance requirements must be described.”
• The municipality: “We suggest that owners with
common interests organize themselves.”
• The director of the school: “I am inspired by the ideas
of the conservationists, e.g. the internal navigation.”

The network started in November
2011
Participants are 10 companies
and foundations
Research topics are determined
by the participants themselves
This also applies to the themes of
the meetings

Interests of residents
•
•
•
•
In the Netherlands at least 70% of the residents has to agree with the
renovation plans before a housing corporation can start with the renovation.
Interventions inside cause inconvenience for the residents. Many residents
therefore prefer to do nothing, unless there are other benefits...
Most houses in the Gordel ’20-’40 are small. During renovations the
surfaces can increase. Sometimes this leads to fewer homes.
Residents would like to have (larger) outdoor spaces.

Sustainable solutions for each building,
combined with collective solutions and
smart energy distribution
New funding for the transformation of vacant
heritage buildings
Professionals and non-professionals look creatively
for new fundings:
• Energy Service Companies (ESCo’s)
• Crowd Funding
• GreenLease
Seinwezen, Haarlem: Industrial heritage
• New function: office rooms for an advertising
agency, meeting rooms, working places for selfemployed without staff
• Social entrepeneurship: crowd funding,
neighborhood participation (urban farming, solar
energy, cultural events, local health care system)

Garden Cities in Hilversum
•
•
•
•
Two garden cities in Hilversum are
nominateds as conservation areas
Residents fear that no interventions
will be allowed in the future
The municipality organized
information meetings in the evenings
to discuss expected possibilities and
restrictions
Will solar panels on the roofs be
allowed or not? ‘We will be confronted
with the taste of our neighbours. Thus
we have to make agreements.’
Garden Cities in Hilversum
•
•
•
•
•
Solar panels will be allowed on roofs
that ar enot visible form poublic
streets and squares
Preferably they will be placed on the
roofs of annex buildings like barns
and car ports
Discussion about the possibilities for
interventions in a determined strip on
roofs visible from public streets and
squares
Information about other sustainable
interventions is provided
Collective initiatives will be supported
Garden City in Vreewijk, Rotterdam
•
•
•
•
Innovationlab with residents and professionals
For residents the character of the neighborhood
is very important
They wish well maintained gardens, no vacant
homes and shops, good public transport,
common activities, homes that are suitable for
elderly people,…
Together they made an ‘exposition of ideas’
Historic churches in Deventer
•
•
•
•
•
Six churches in Deventer: What are frequently
ocurring situations and possible solutions?
Occasional use, large volume, outer shell is not
insulated, organ requires constant temperature,
obsolete installations (often air heating)…
Municipality provides a website to promote other
functions in the church (weddings, concerts,
expositions, etc.), aiming at additional income and
more regular use
Insulation of attic floors, insulation of roofs only
when renovation of the roof is required anyway
New installations: basic heating / peak, potentials
of the neighborhood?
Historic Schools, Hilversum
•
•
•
•
•
Famous architect Dudok:
characteristic architecture
in Hilversum
Parents complain about
poor indoor climate
School boards complain
about high energy bills
Suspended ceilings,
children working on the
corridors, windows that
cannot be opened, etc.
How to use historic
potentials?
Jaromir –project: idea for an international cooperation
•
•
•
EU-calls may offer possibilities for
international co-operation
Alliander, a Dutch energy supplier, wants
to start up a pilot project in the historic
city center of Zutphen.
Based on the ideas that sustainable energy
concepts have to be developed with
respect for the cultural value of heritage
buildings AND that collective solutions in
this situation are more promising than
solutions for individual buildings.

A sustainable energy concept for the Walburgis
church and buildings in the direct neighborhood,
among them offices, houses and a hotel.
‘Jaromir-cycle’ of A.C.W. Staring, Dutch poet
of the 18th century: ‘Jaromir in Prague’,
‘Jaromir in Lochem’, ‘Jaromir in Zutphen’,
‘Jaromir revenged’.
Alliander suggested to initiate a co-operation
with Prague and Lochem in order to exchange
ideas and identify possibilities for collective
sustainable solutions in the neighborhood of a
historic church.
Including not only the technical, financial and
historic aspects but also social potentials for the
local community.
Dutch Canadian Network: Parallel 52
•
Mutual enthousiasm about a Dutch/Canadian collaboration on the field of
sustainable building
Parallel 52
•
•
•
Step 1: Making use of opportunities: organizing lectures and meetings
whenever professionals visited The Netherlands/Canada. Embassies helped
by informing Nyenrode whenever professionals where visiting the country.
Step 2: Embassies and consulates supported the network by hiring interns.
They contacted companies, made a flyer and publication, created a website,
organized virtual meetings etc.
Step 3: The network is supported by a couple of companies. They sponsor
travel expenses, costs for hosting virtual meetings, pay for printing flyers
etc.
Parallel 52
•
Situation now: Companies, governments and universities are partners of the
network. Current activities are virtual discussions, results preseendt during
conferences, lectures of Canadian professionals at Dutch universities,
workshops, etc.
