This presentation was give in the opening session of the REHVA 2015 conference in Riga on May 8 2015. It deals with the topics of good EPC compliance as well as good quality of energy related works, with a specific for the status on the ground and possibilities for improvement.

8. 2 societal expectations…
• There should be (more) attention for compliance
with the EPC for new and renovated buildings
• There should be (more) attention for achieving a
good quality of the works

10. Energy certificates with respect to ventilation …
EPC calculation
• Efficiency of heat exchanger
• Fan characteristics
• Ductwork airtightness
• Demand controlled ventilation
• …
• …
Execution of the works
• Air flow rates
• Acoustics
• …
• …
Observation:
In many countries no or nearly
no control regarding
compliance of EPC
Observation:
In many countries no or nearly
no control regarding
real performances

11. Poor design and
execution
• Energy performances
critical
• IAQ problematic
• acoustics
• Maintenance
• …

13. Which problems are often observed?
• Air flow rates ( IAQ)
• Acoustics: from system or from outside
• Draught problems
• Maintenance
• …
• Problems are found for all kind of systems
• Good execution
exists and also not
extremely difficult

15. 2 objectives of QUALICHeCK project
• To set up a series of actions which should result in more attention and
practical initiatives for actual compliance with the claimed energy
performance for new and renovated buildings
i.e. ‘Boundary conditions which force people to do what they declare’;
• To set up a series of actions, which should result in more attention and
practical initiatives for achieving a better quality of the works,
i.e. ‘Boundary conditions which stimulate and allow the building sector to deliver good
quality of the works’.

NUMBEROFPROJECTS
OUTOF15EXAMINED Example from CYPRUS: Deviations between U-values
in EPC and the actual U-values

26. Example from FRANCE:
Quality of ventilation systems in 1.287 new dwellings
44 % of multi-family dwellings don’t comply
68% of single-family dwellings don’t comply

27. Example from the Netherlands
November 2014:
“Ventilation Improvement plan has failed”
• This was a statement by Dutch minister
• Context:
• Findings in 2012: 50% of new residential ventilation systems don’t work well
• All stakeholders’ organisations signed in 2012 a declaration that in 2015 all systems should
function correctly
• Reasons for failure:
• … lack of interest by clients
• … economic pressure

33. Special issues by QUALICHeCK
for REHVA Journal
3 special issues are planned:
•1st issue August 2015
•2nd issue around June 2016
•3rd issue around February 2017

34. Procedures to obtain and prove
compliant data
Robust legal procedures in case of
non-compliance
Handling of non-compliance in
practice
There should be clear procedures
what must be done
There should be clear legal procedures how
to decide on non-compliance and related actions
There should be an effective control
and sanctions if non-compliance

•Should there be more attention by the Member
States for compliance and quality of the works?
•Should these issues receive attention in the
framework of a review of the EPBD?

45. Conclusions
• We have to be ambitious in terms of the requirements imposed
for the energy performances of new and renovated buildings
• But it is also very important to create boundary conditions that:
• Result in good compliance (a ‘reliable’ EPC)
• Result in good quality of the works
