The project tries to develop knowledge in integrated solutions that link energy and design of existing buildings. Centrally important is the dissemination of information about energy and environmental-and climate-friendly solutions in housing and building and sustainable living and building / architecture. Three different buildings were examined: • Linesøya school building • Fire station in Surnadalsøra • Rotvoll barn at Camphill / Steiner school in Trondheim. What became obvious is that the ambitions of a project are an important factor. They not only define the success of the project in terms of measurable CO2 emission reductions but also predefine sets of solutions that are applicable. Keywords: architectural design, energy efficiency, community commitment. OPEN ACCESS
