Comparing requirement levels
: 0,8
: E100
REHVA Seminar, May 14 2009WP 2: Comparing EP-requirements in Europe4
Just compare kWh/m2! …?
• Differences between Member States:• Climate conditions• Indoor conditions• Building practice• Building use• Assessment method: subsidiarity principle
REHVA Seminar, May 14 2009WP 2: Comparing EP-requirements in Europe5
IT LOOKS MORE EASY THAN IT IS !!!
REHVA Seminar, May 14 2009WP 2: Comparing EP-requirements in Europe6
In short: compare the baskets…
Imagine a basket with the typical measures needed to fulfil the national minimum requirements
• For a common reference building
Country ACountry B
??
Comparison:
Not only the types of fruits
But also: if “apple A” is equal to “apple B”

Pilot studies ASIEPI
• Pilot study 1:• Predefined:
• dimensions (incl. windows) & orientation

Consequence of different measures
• Annual energy use: 75.000 MJ
• France: 123 m2 610 MJ/m2
• Germany: 153 m2 493 MJ/m2
Almost 1/4e
more!

Pilot study step 2: preconditions
• Heating & DHW system:• Combined Condensing boiler
• Ventilation system:• Natural supply, mechanical exhaust
• No additional solar collector or PV system

Consequences
• Heating system not included in all MS:• Case 1: house with non-condensing boiler• Case 2: same house with condensing boiler• Case 3: same house with heat pump
Example (fictive figures!!): DK FI
Case 1: Uav. = 0,20 Uav. = 0,35Case 2: Uav. = 0,35 Uav. = 0,35Case 3: Uav. = 0,50 Uav. = 0,35
Conclusion, based on: • case 1: EP requirement in DK more strickt as is FI• case 2: EP requirement in DK as strickt as is FI• case 3: EP requirement in DK less strickt as is FI
