Abstract The Swedish research project 'Potential and Policies for Energy Efficiency in
Swedish Historic Buildings' aims to investigate the interdependency between political
energy targets and effects on the built heritage. The first part of this paper presents an
iterative and interactive method to assess the potential for and consequences of improving
the energy performance in a stock of historic buildings. Key elements in the method are:

This paper presents and demonstrates a multidisciplinary method to assess the potential for
and consequences of improving the energy performance in a stock of historic buildings. The
key elements in the method are categorization of the building stock, identifying targets,
assessment of measures, and life cycle cost optimization. The method is applied on the
historic building stock of the word heritage town of Visby. Based on a systematic
categorization, building archetypes are selected to represent the whole building stock. The …
