This report provides a framework to help groups of users and/or owners with the ambition to improve the buildings’ energy performance. It focuses on buildings that are used/owned by different stakeholder groups.

Research conducted within the RES4BUILD project (Spijker E. , et al., 2020) (Spijker E. , et al., 2022) has shown that there are significant barriers to implementing energy efficiency saving measures in buildings that are used by groups of different stakeholders. These barriers are particularly prevalent in existing buildings (relative to new builds), where deep renovations are needed, and collective (investment) decision-making processes are complex (i.e. involving and affecting many stakeholders). Those implementation barriers are generally of technological, financial, and social-organisational nature.

We promote the deployment of Integrated Energy Solutions (IES), in contrast to the consecutive deployment of single technology measures over a longer period, as a way to more effectively and efficiently make use of limited resources (e.g., labour, materials, time, finance). IES combines several energy saving measures, and renewable energy technologies that together can ensure that a building(s) can comply with whatever energy- and/or climate neutrality targets are set.
