In connection with the international housing exhibition Bo01 in Malmo, Sweden in 2001, several residential units were built. To get building permission, all developers had to present calculations proving that their buildings would use in total less than 105 kWh/(m(2.)year) bought energy. Measurements show that none of the buildings fulfilled the demand concerning energy use. According to the calculations executed by the developers, passive solar heat gain represents a large portion in the energy balances for the buildings. It is not likely that such a large portion of solar heat gain can be used. However, large glazed areas facing south and west, which is the case in these buildings, might lead to major heat contribution through solar radiation and there is a risk of having too high indoor temperatures. Measurements have been done to investigate what effect passive solar heat has on energy use and indoor temperature.
