Abstract: The Swedish energy performance certificates for single family housing provide rich information on energy consumption and various physical attributes. They also include estimates of the energy conservation potentials resulting from implementing cost-efficient energy saving measures. By matching the certificates issued for single family houses in 2009 and 2010, with data from other sources we have created a unique data-base which can be used to explore a wide variety of questions related to energy consumption and conservation. One aim of this paper is to assess the role for energy consumption played by socio-economic characteristics of the residents as compared to physical attributes of the house. Another is to estimate the influence of housing attributes and climate on the “engineering estimates” of the conservation potentials and analyze to what extent the two estimated relationships are consistent. Our results show that while the quantitative impact of physical attributes dominate the energy use for heating and cooling, the opposite holds for the consumption of household electricity. The assessed conservation potential, amounting to 15 percent of the energy consumption, is significantly related to both the housing attributes and the energy consumption. The results also indicate a need to improve the information provided by the performance certificates.
