How to improve the EPBD
impact, how to assess better
innovations?
The point of view of EuroACE and
Aereco
© Aereco 2008

Founded in 1998 by 20 of Europe’s leading companies
involved with the manufacture, distribution and
installation of energy saving goods and services.

In response to European Council of Ministers proposals
to combat the threat of climate change, which
completely ignored any potential for reducing
energy consumption in buildings.

EuroACE works together with the European institutions
to help Europe achieve greater sustainable energy
use in buildings and significant reductions in
carbon dioxide emissions.

Goals
The challenge:
To ensure that not only is the potential for saving energy in
buildings recognised, but policies are introduced.
To stimulate investment in all energy efficiency measures in
buildings.
Methods:
Continuous dialogue with those in the European Union
charged with delivering programmes.
Several substantial research projects, intended to facilitate
effective policy making in this area and expand the market
for EuroACE's members' products and services.

Research, design and manufacture of
energy efficient domestic ventilation
systems
Founded in 1984
Head office and factory in France, 10 subsidiaries and offices Worldwid

Inventor of the humidity sensitive ventilation system in 1984
Specialised in Demand Controlled Ventilation

Assessment of Demand Controlled
Ventilation (DCV) in the EPB
3 cases in the EU:
Assessment and value available in the regulation framework
(France, Humidity controlled ventilation)
Assessment not available in the “standard” tools, but specific
procedure/method to assess the performance (ATG- E in
Belgium)
No possibility to assess or value the performance of DCV
(case of most of the countries)

Ventilation in France
Technical Approval (delivered by CSTB*)

when using Demand Controlled Ventilation

Ventilation in France
Principle of equivalence (average controlled airflow
equivalent to a constant airflow at same IAQ), given by
technical approval delivered by CSTB.
Advantage = enable the use of the existing calculation tools.
BUT need of complementary certified supports (technical
approvals).

To assess a product… or a system?
EPBD’s principle is to improve the global
performance of the building.
The energy performance of a product depends strongly on its:
Environment (system and other influencing elements)
Tests conditions

Same engine, different car energy performance…
The complete system can be energy-labeled, not
the product/component.

The use and the environment of the product should
always be taken into account to assess its EU energylabel.

Regulations and innovation
Regulations = Picture of the state-of-the-art with the
available technologies.
Regulations can be considered as barriers for
innovation as soon as they are not able to value
improvements on energy performance supplied by
a new technology.
Need for frequent evolutions of regulations and
calculation tools to better take into account efficient
innovations.

Conclusions
The lack of assessement procedures and the length for
technical approvals are real barriers for innovations in regard
with EPBD.
Assessment of complete system is more representative than
a product or component assessment.
Principle of “equivalence” is a fast and efficient way to enable
and to assess innovation without revolutionning the existing tools.
While calculation tools must be easy to use, simplification is
not always possible: it does not enable to take into account the
specifities of the innovations.
