WP 2: Comparing EP-requirements in Europe
Comparing requirement levels : 0,8 : E100 WP 2: Comparing EP-requirements in Europe
Just compare kWh/m2! …? • Differences between Member States: • Climate conditions • Indoor conditions • Building practice • Building use • Assessment method: subsidiarity principle WP 2: Comparing EP-requirements in Europe
IT LOOKS MORE EASY THAN IT IS !!! WP 2: Comparing EP-requirements in Europe
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 A Country B Comparison: Not only the types of fruits But also: if “apple A” is equal to “apple B” WP 2: Comparing EP-requirements in Europe
Pilot studies ASIEPI • Pilot study 1: • Predefined: • dimensions (incl. windows) & orientation WP 2: Comparing EP-requirements in Europe
Results pilot study 1: Some interesting figures: WP 2: Comparing EP-requirements in Europe
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! WP 2: Comparing EP-requirements in Europe
Results pilot study 1 CB = Condensing boiler NCB = Non-Condensing Boiler DH = District heating Nat. = natural ventilation Mech. = Mechanical ventilation Ns/Me = Nat.supply & Mech.exhaust WP 2: Comparing EP-requirements in Europe
Pilot study step 2: preconditions • Heating & DHW system: • Combined Condensing boiler • Ventilation system: • Natural supply, mechanical exhaust • No additional solar collector or PV system WP 2: Comparing EP-requirements in Europe
Results pilot study 2 CB = Condensing boiler Ns/Me = Nat.supply & Mech.exhaust WP 2: Comparing EP-requirements in Europe
Items within EP requirement WP 2: Comparing EP-requirements in Europe
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. = 0,35 Case 2: Uav. = 0,35 Uav. = 0,35 Case 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 WP 2: Comparing EP-requirements in Europe
Results pilot study 3 CB = Condensing boiler Ns/Me = Nat.supply & Mech.exhaust NCB = Non- Condensing boiler WP 2: Comparing EP-requirements in Europe
Pilot study Step 4 • Simple calculations • Result • DE: 53.000 MJ • BE: 56.000 MJ CB = Condensing boiler Ns/Me = Nat.supply & Mech.exhaust WP 2: Comparing EP-requirements in Europe
Pilot study Step 4 • Simple calculations • Result • DE: 53.000 MJ ? 55.000 MJ ? • BE: 56.000 MJ ? 54.000 MJ ? Thermal bridges ?? Air tightness ?? CB = Condensing boiler Ns/Me = Nat.supply & Mech.exhaust WP 2: Comparing EP-requirements in Europe
