Passive house pioneer in Salzburg

23 years after the first passive house in Salzburg, we with the pioneer and his energy saving Haus. Construction details became a lifework: Sera wall heating

Passive house pioneer in Salzburg: Ing. Heinz Eggert
	With an energy demand for heating like 400 to 500 litre fuel oil equivalent for 170m² living space, the house from 1980 is within todays standards for passive houses.

Air collector roof
	Direct below the aluminium roof ascend warm air. The air heated by the warm roof is pulled by a 300 Watt ventialator through cavums in the walls.

Night insulation for the windows
	In winter are 2/3 night and 1/3 day. To reduce thermal looses in the long winter nights, all windows and glas doors are with a foldaway thermal protection.

Sera wall heating from the passive house in Salzburg
	To have more comfort and less energy damand, Ing. Heinz Eggert developt 1979 a wall heating for his passive house project.

Low energy house after 23 years
	23 years degraded the passive house performance. Special the air tightness of the windows worsened. The energy demand doubled.
