The Maintenance-Free House (New Materials) is part of a large development project: The MiniCO2 Houses. The project involves a total of six detached houses, each of which illustrates various aspects of reducing CO2 emissions in the construction, use and maintenance of a house. The Maintenance-Free House focuses on “maintenance and service life” and examines how much CO2 can be saved when a house is built to have a service life of at least 150 years, and the building envelope needs no maintenance for the first 50 years of that service life. House A has been constructed using traditional materials, which have proved their long service life, and House B – described here – has been constructed using new materials, which are expected to have a long service life. Maintenance-Free House B has been constructed as a long house with a covered east-facing entrance located exactly in the centre of the building’s longitudinal side and a 40-degree pitched roof. The interior of the house has been designed as a wooden “box”: one large continuous room with open beams and furnished with low closed boxes. Daylight enters through the four skylights, from the entrance area, from the full-height windows and doorways in the end walls, and from an approx. 10-meter long glass section.
