Context - Minimum thermal performance standards for residential building envelopes have been increasing in many countries for several decades, addressing concerns about occupant comfort, operational costs and greenhouse gas emissions. Simulation tools play a role in assessing the space heating/cooling load of new buildings and for evaluating options for systematic retrofitting of exisiting dwellings. The...

Purpose / Context – Energy efficiency measures/ private home-owners/ decision process Methodology / Approach –Explorative research/ qualitative interviews/ content analysis Results – Decisions towards energetic renovation measures can be characterized as a strategic consumer decision rather than the often assumed purely investment decision.
