About one third of Swedish buildings were built before 1945 and they constitute an important part of our built heritage. But these buildings also stand for a significant part of the Swedish energy use. This paper is part of the research project 'Potential and policies for energy efficiency in buildings built before 1945' that assess the capacity for energy saving in buildings built before 1945 with regard to historic values in the buildings. The purpose of this paper is to assess energy saving measures that will reduce the energy use by 20, 50 and 70 % respectively in a typical single family wooden house from the 1920s. Primarily, this paper focuses on moisture safety. It also aims to highlight the difficulty of significantly reducing the building energy use without altering the building's character and historic value. The work includes assessing the existing energy use in a fictitious 1920s building and identifies three packages of measures that reduce the building's energy use significantly at an optimal life cycle cost while considering conservation aspects. This is done using a methodology and a tool, OPERA–MILP,developed by the research project. The proposed energy saving measures, on both the building envelope and the building services, are then assessed from a hygrothermal performance perspective using the ByggaF methodology.
