1. Energy Certification of New Buildings
Lessons Learned, Mistakes to be Avoided
Seminar on Energy Performance of Buildings
Nicosia Cyprus, 7th December 2005

2. Experience Certification Buildings
Existing experience with energy Certifications of New Buildings
Existing Schemes
Experience and discussions from Concerted Actions:
Lessons learned
Mistakes to be avoided

3. Not a simple question !
The types of certification is different in different countries
Often done / different in regions
Many aspects included in certification
Should auditing be included ?
25 member states
Associated countries
Candidate countries

4. Larger certification experience
A few countries have more advanced certification schemes which have been in action for some years
Among those countries are:
Austria (länder)
Denmark
Germany (länder)
Netherlands UK
(I am sure forgot someone)
Some countries more than one scheme or even many !
JHL / Energy Efficiency and Economy

5. Certification experience
Certification of New Buildings is also an issue outside Europe and major experience are found in for instance:
USA (different states)
Australia
Some countries more than one scheme or even many !
JHL / Energy Efficiency and Economy

6. Certification of Building
Most schemes have been voluntary, but in some cases combined with strong incentives, like subsidy or grant programs
Most schemes have been focusing alone on efficiency in new buildings
Some have been focusing only on public buildings
So far only one country has used mandatory schemes for existing buildings

8. SAVE Projects
Quite some countries have been involved in SAVE projects - which include development and testing of certification schemes
Some of those projects are still going on
Alone one project with certification of public buildings has involved or even more countries
Most projects are limited in geographic area and in types of buildings included in the project

9. Pilot studies
In many countries pilot studies are going on before the implementation of the real EPBD scheme 2006
Those project a very different in size and organisation
Big projects are going on in Germany, Sweden ....
More projects will start soon
New Framework VI programmes will include testing of methods and schemes
I am for instance involved in 2 different projects
Quite some projects run as cooperation with old and new member states

10. Aim of Certification and when ?
Certification in New Buildings can have two different aims
Certification on project stage
Certification can easy influence energy consumption and building design
Certification after construction
Certification can control actual building and changes made under construction
Need for both !
But only few countries dare to make both
JHL / Energy Efficiency and Economy

11. Certification on Project
When Certification is done under construction:
it is easy to adjust the project
savings can be made with small costs
will influence a good design of buildings
but:
certification must be made on drawings etc.
projects undergo major changes
when is the exact right time
consultant should be in place for a long time
JHL / Energy Efficiency and Economy

12. Certification after Construction
When Certification is done after construction:
it can control the final building including changes
it can be used a approval of low energy or passive-house
will be a real declaration of the consumption
but:
difficult to change buildings after construction
some parts of the building are hidden
will optimise construction not design

14. Certification as a Positive Label
Energy Certification can especially be used as a positive mark or label for new building which are better than the requirements
This can be based on certification by project or after construction,
but only the last will be like a quality mark !
Quite some countries have experimented with this:
Germany, Austria, England, USA or Australia

16. Experience from the CA In the Concerted Action EPBD
discussions have been
Which certification to choose ?
Can you gain the results of both ?
Could self calculation or certification be a way ?
What can you do with hidden constructions ?
Just to mention some the questions

19. Brussels - Posters New Buildings
In September in Brussels we had posters from 23 countries and the 3 Belgian regions
Most Countries were i favour of certification after construction (14)
Nearly a third wanted before (8)
Only 2 would do both
2 countries had not yet decided in September
Some countries which would certificate before would claim random check after construction.
Some countries would use architects or engineers for certification and in a few cases this would be checked
Most countries wanted to use independent experts

21. Certification in Sweden
Certification of New Buildings in Sweden (Per-Erik Nilsson, CIT)
1. step:
application to have a building permit must be followed by a certificate
2. step:
2nd certification 2 years after the building was handed over for non-res 5 years (based on operational rating)
definition: asset rating during design phase should be called design rating; in fact more tailored rating
approach follows CEN in some aspects not in every one

22. Certification in Finland
Certification of New Buildings in Finland (Timo Husu)
main principles of CEN will be followed
calculation will be part of the design process, results are needed for application for permit
reference values for components and systems will be given
energy certificate will be made during design
verification will be part of commissioning process
according to building code would result in class D!!!
first draft of this law under public consultation in summer 05, law will be finished early 2006, in force during 2006

23. Certification in Spain
Certification of New Buildings in Spain (J. Molina)
12 climate zones in Spain
17 different regions
Cooling and Air-condition
Simplified method for residential buildings
Non residential buildings very different - based on CO2
Large studies on calculation methods and categories done
Large administration needed in Spain
alone in Andalusia certificates pr. year
and 140 administrators could be needed for registration

24. Certification in Denmark
Certification of New Buildings in Denmark
Will combine certification after construction
and self calculation and reporting before buildings permit
Consultant will asses building and will control self reporting
Consultant can claim documentation for closed constructions
Will use certification to ensure fulfilment of building regulation
Will use certification to promote low energy buildings
JHL / Energy Efficiency and Economy

25. Low Energy Classes
Energy performance New Buildings: / A (kWh/m2 year)
Low energy class 2
75 %
Low energy class 1
50 %
Use of solar energy and efficient systems is needed !

29. Facing the future
In the next years many countries (25 ++) will gain more experience with certification schemes !
The Danish experience is: Will still be use of development of certification and new information after day one !
Share of experience must go on after 1st of January !
