In 2009 we produced Swedens first series of passive house designs. Our goal is to make this environmentally friendly building technique available for all. In 2010, Villa Nyberg was developed and built from our design for the Passive House; 'Villa Atrium'. It is the first house in the series to be taken through to construction. The villa has been customized for the Nyberg family and is situated in Borlänge, central Sweden.
THE PASSIVE HOUSE CONCEPT: Passive houses are extremely well-insulated buildings that are largely heated by the energy already present in the building - people and our household equipment generate a lot of energy. Our energy simulations show that this villa will have an energy consumption for heating of only 25 kWh/m²year.
SWEDISH RECORD IN AIR TIGHTNESS: To reduce heatloss air tightness is an important feature of a passive house. When we tested the air tightness of Villa Nyberg in a blow-door test we got a pleasent suprise, a new Swedish record! The result was 0,038 l/sm² at 50 Pa. The Swedish passive house standard is 0,3 and the previous record was 0,07.
DESIGN PRINCIPLES: The villa is situated by a lake in a pine forest in central Sweden. The living room and kitchen open up towards the views of the lake, the more private areas such as the bedrooms and bathrooms are situated on the other side of the house with smaller windows overlooking the forest. The round shape of the villa eliminates cold-bridges and reduces the enclosing wall area of the house. It also effects the way you live in the house, during the day one will move from room to room around the building experiencing different views and daylight conditions.
LIVING IN VILLA NYBERG: Its Sunday morning and I’m reading the newspaper in the kitchen. The autumn is closing in, but its still warm in the sun. From here I can almost see all the rooms of the house. The kitchen and the living room form one big open room to my left and hall way to my right connects me to the other rooms of the house. Through the atrium I can see the doors to the bedrooms on the opposite side, there our kids are still fast asleep, they stayed up a bit too late last night watching movies.
