During a test regime, which includes seven overnight periods, and which totals between 6 to 42 hours of measurement, the thermal heat loss volume coefficient is determined for a building(1) from measurements made in stages as follows: - regulate each electrical heating appliance to the same set temperature value at least 48 hours before taking measurements, and maintain this setting until the end of measurements; - during each measuring period, measure at frequent time intervals the electrical energy consumed by the heating system as well as the temperatures inside and outside the building; - calculate the heat loss coefficient from these measurements.
