The energy use in the existing building stock must be reduced and historic buildings need special attention, both in terms of practice and policies. The general objective of this study is to provide an improved evidence base regarding the energy use in the historic residential building stock in Sweden. Data from the Swedish data base of energy performance certificates (EPC) has been used, which are based on measured energy use. The aim is to use the building energy data to inform on the energy use in historic buildings. Since national data on heritage values in the building stock are unavailable age, is used as a proxy, and buildings built before 1945 are studied in more detail. In the study policies for energy targets are compared with the real energy performance of the older buildings in the building stock, and based on the results their possible contribution to energy saving on a national level is discussed. Buildings built before 1945 stand for a significant part of the energy use in the Swedish building stock, and well planned measures, taking heritage values in account, could achieve significant energy savings. Buildings built before 1845 account for a very small part of the energy use for buildings and should not be prioritised in achieving national targets for energy saving. Buildings built 1945–1974 are those that use the most energy and where renovation could have limited impact on heritage values. Apartment buildings with district heating built between 1845 and 1945 have an average energy performance that is twice the target for new and renovated buildings. The average value or the mode value of the group could be assumed to represent a realistic target. Using this method we could identify buildings or groups of buildings that represent best practice in a given segment of the building stock. General targets for energy saving when applied to historic buildings can result in negative effects on the heritage values of the buildings. This method and the results of this study can be used to set more realistic targets for policy planning and renovation aiming to improve energy performance in the Swedish historic building stock.
