[edit] Abstract
Improving the energy performance of historic districts and their buildings is a balancing act between retaining their heritage significance and allowing the installation of retrofit measures. This paper describes a heritage impact assessment methodology to enable such a balancing process in a well-structured and systematic way. The methodology is one of six impact assessment modules for a decision support system, a software tool under development for the research project Energy Efficiency for EU Historic Districts’ Sustainability (EFFESUS). In this paper, the three parts of the methodology – the heritage significance evaluation, the heritage impact definitions and the heritage balancing process – are discussed and their use illustrated by two example case studies.
