Analysing energy considerations in residential renovation planning and design: a case study comparison between Denmark and Sweden

Abstract This paper investigates the dynamics surrounding energy efficiency measures in building renovation projects to understand how energy issues are dealt with at planning and design meetings for building renovations. Through a comparative analysis of case studies of residential building renovation projects in Sweden and Denmark, document studies, observations, and interviews were conducted. The study revealed barriers hindering the effective implementation of energy efficiency practices and discussed how these can be overcome. Despite a growing recognition of the importance of energy issues, professionals often prioritise design aspects and technical installations over energy saving or efficiency. Conventional renovation practices limit the adoption of more innovative or advanced energy-efficient solutions. Financial constraints and a lack of focus on energy performance were significant barriers to the implementation of more progressive measures. Energy calculations as well as energy consultants are not given space and time at the project meetings. Clear guidance and alternative financing mechanisms are crucial for overcoming these hurdles and promoting sustainable building practices.
