kjellgren kaminsky architecture : villa nyberg ' villa nyberg ' by kjellgren kaminsky architecture kjellgren kaminsky architecture has produced swedens first series of passive houses sold as type houses in collaboration with emrahus . their goal was to make this environmentally friendly building technique available for all . ' villa nyberg ' is the first one to get built . the villa has been customized for the nyberg family and is situated in borlänge , central sweden . 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 . their energy simulations show that this villa will have an energy consumption for heating of only 25 kwh / m ² year . to reduce heatloss airtightness is an important feature of a passivehouse . when they tested the airtightness of ' villa nyberg ' in a blow door test they got a pleasent suprise - a new swedish record . the result was 0 , 038 l / sm ² at 50 pa . the swedish passive house standard is 0 , 3 and the previousrecord was 0 , 07 . the villa is situated by a lake in a fur 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 overlookingthe forest . the round shape of the villa eliminates coldbridges and reduces the enclosing wall area of the house . it also effects the way you live in the house , during the day one will movefrom room to room around the building experiencing different views and daylight conditions . the autumn is closing in , but its still warm in the sun . its sunday morning and i ’ m reading the newspaper in the kitchen . from here i can see almost the whole house . the kitchen and the living room form one big open room . from there two corridors running along the atrium connects it with the bedrooms . if i look into the atrium i can see the doors to the bedrooms on the other side , there our kids are still fast asleep , they stayed up a bittoo long yesterday watching movies . e l e v a t i o n elevationelevationsection viewthe design conceptthe design conceptthe design conceptproject info : project name : villa nybergclient : emrahus & the nyberg familyobject : prefabricated passive house villasize : 156 sqm . stage : builtteam : joakim kaminsky , fredrik kjellgren , oscar arnklitt , daniel andersson , corina bermúdezridhika db 06 . 21 . 10
