Silvervillan is located in Skilleby, Järna, Sweden, which is considered to be a very sustainable region due to its organic farms and local production of bread, cheese, and fruit juices. The owners also wanted to ensure that their home was low-impact to they contracted Sjöberg & Thermé to design and build a home with a high performance envelope that would minimize heat loss and heat gain. The house is built with 2 separate construction frames for the walls. 45 cm cellulose insulation in the walls and 60 cm insulation in the ceiling/roof gives the home a U-value under 0.1.
The home features an open floor plan living/dining/kitchen area on the ground floor with 4 bedrooms and 2 baths. The upstairs loft has a play room and another living room. Natural daylighting makes the home open and bright, while the ventilation system is designed for those with asthma and allergies. A solar hot water heating system on the south side of the house provides domestic hot water. With the tight envelope and energy-efficient systems inside, the house only uses 6,500 kWh/yr. Compare this figure to the US average of 11,496 kWh/yr and the savings are clear.
