Using the energy signature method to estimate the effective U-value of buildings
The oil crisis of the 1970s and the growing concern about global warming have created an urge to increase the energy efficiency of residential buildings.Space heating and domestic hot water production account for approximately 20% of Sweden’s total energy use. This study examines the energy performa...

The oil crisis of the 1970s and the growing concern about global warming have created an urge to increase the energy efficiency of residential buildings.Space heating and domestic hot water production account for approximately 20% of Sweden’s total energy use. This study examines the energy performance of existing building stock by estimating effective U-values for six single-family houses built between 1962 and 2006. A static energy signature model for estimating effective U-values was tested, in which the energy signature was based on measurements of the total power used for heating and the indoor and outdoor temperatures for each studied house during three winter months in northern Sweden. Theoretical U-values for hypothetical houses built to the specifications of the Swedish building codes in force between 1960 and 2011 were calculated and compared to the U-values calculated for the studied real-world houses. The results show that the increasingly strict U-value requirements of more recent building codes have resulted in lower U-values for newer buildings, and that static energy signature models can be used to estimate the effective U-value of buildings provided that the differences between the indoor and outdoor temperatures are sufficiently large.
