Analysis by measurement of energy consumption in full scale model houses

Discusses measurement of energy consumption and the large number of factors to be studied. Presents detailed measurements for two blocks of flats in Sweden taken partly during 1971/72 and partly during the oil crisis of 1973/74. In one of the two projects major savings were achieved by adjusting the heating system, reducing the room temperature and reducing the mechanical ventilation. About half of the savings made in the energy used for heating and ventilation (40%) resulted from reduced airing of rooms.
