Two passive house centrums in Sweden!

Sweden is lucky to have many engineers dealing with design and building of a passive house. There exist two passive house centrums, Passivhuscentrum Västra Götaland in Ålingsås and Intressegrupp Passivhus (IG PH) in Växjö.

IG Passivhus deals with the German passive house, i.e. with the passive house defined based on the original definition by Passive House Institute (PHI) in Germany.

  • Heating/cooling demand: 15 kWh/(m2.a) for new buildings or 25 kWh/(m2.a) (or heating/cooling load 10 W/m2)
  • Air tightness of n50 < 0,6 h-1
  • Primary energy demand of 120 kWh/(m2.a)

Passivhuscentrum deals with the Swedish Passive house, i.e. with the passive house defined for the Swedish conditions by FEBY 12.

  • Heating load demand: 19 W/m2 for I. zone (Northern Sweden), 18 W/m2 for II. zone (Middle Sweden) and 17 W/m2 for III. Zone (Sweden Sweden)
  • For non-electric heating systems: 63 kWh/(m2.a) for I. zone, 59 kWh/(m2.a) for II. zone and 55 kWh/(m2.a) for III. Zone
  • For electric heating systems: 31 kWh/(m2.a) for I. zone, 29 kWh/(m2.a) for II. zone and 27 kWh/(m2.a) for III. Zone
  • For combination of different type of energy systems: 78 kWh/(m2.a) for I. zone, 73 kWh/(m2.a) for II. zone and 68 kWh/(m2.a) for III. Zone
