It is that time of year again. Passive houses all over the world are made available by their owners for interested people to visit. The international database lists passive houses all over the world, very interesting reading. Please observe that all houses are not certified in Darmstadt, but all of them are analyzed with the German PHPP programme. (Passive house planning package)

Scandinavian Homes participate with our original Galway passive house in Moycyllen (Hibernia 164) and also with our new passive rental apartments (Skagarrak 304) in Lysekil, Sweden. All interested welcome!

Sun heats supply air in old house built in 1860

Our old merchants house from 1860 is principally built in the same way as any new Scandinavian

Homes building. The biggest difference after renovation is that the old cold attic is now (sort-of) within the heated envelope. This was achieved by simply insulating the roof externally with 300mm of insulation. The attic is cool in the summer and warm in the winter.

This is also an ideal location for our ventilation systems. We used four of the old faithful REC Temovex 400 to heat and ventilate the entire building. (The production of this model has stopped, so if anyone wants one, get the order in quickly, the factory have only a few left in stock).

Hot water from our solar tank heats the supply-air in simple VEAB wet-duct-heaters. This works well and the air does not become dry and uncomfortable. Reason is that in passive, (or near passive as this house probably is) we need only to supply 10W per square meter floor-area on the coldest day of the year. In winter when the heat in the solar tank is depleted we use the county-council district-heat to top up the temperature.

This is not recommended in a regular poorly insulated house because the supply air temperatures need to be so high to distribute enough energy out in the house. The supply-air can feel dry and unpleasant is such cases.
