An evaluation of previous policies on energy efficiency in buildings and their effects on energy use and historical values, Sweden 1974-2014

Time period: 2015-09-01 to 2018-12-31

The project aims to: 1) evaluate the design and implementation of previous policies focusing on increased energy efficiency in existing buildings, 2) understand how the conservation movement has related to energy efficiency in buildings since the 1970s. In 1973-74 the first oil crisis occurred leading to rapidly increasing energy rates and to national policies on energy efficiency. The starting year of the project is 1974, and the purpose is to examine policies that have been used until contemporary time. The overarching aim is to contribute to our knowledge on how policies have indeed affected the built environment, but also on how the attitudes of the conservation movement towards energy efficiency have developed. In our study we include a shift in perspective from a policymaking level to the single property level, which makes it possible to observe the effects of policies on actual buildings over a period of 35 years. This part of the study is based on a survey of 3,101 properties.
