There is a need to make the existing building stock more energy efficient. For energy efficiency measures in historically valuable buildings to result in a satisfactory result by today’s standards, a competent holistic approach is required.

In projects within the previous “Spara och bevara” programme (Swedish Energy Agency), a methodology for determining the status of existing buildings and risk assessment of energy-saving measures has been developed. The methodology currently addresses building conservation, building biology, and building physics aspects through a common approach. To keep the method relevant, it needs to include circularity aspects and be tested on real objects, which is the focus of this project.

The goal is for the tested methodology to become an established approach in the renovation and energy upgrading of historic buildings.

The immediate recipients of the project’s results are initially the companies participating in the project, companies within the BeBo network, and – over time – the wider construction sector, including consultants, architects, building conservators, contractors, and property managers.
