Based on sustainability, the project will build up a long-term structure for regional collaboration, exchange and building skills to build and manage with the best energy performance in Eastern Sweden. Activities in the project will contribute to development dialogue between research, industry and society. In order to drive the development and use of services and products for the future market of low-energy buildings, a case study in a selection of properties will be conducted. The case study will offer practical knowledge support in measurement methods, monitor and analyse energy use. Companies and organisations involved in the project must have carried out systematic energy work that reduces energy use and climate impact. The project will lead to regional actors building, managing and renovating properties with the best energy performance and with very low climate impact.
