This manual, based on the results of the BewareE project, is intended to inspire and enable ”energy awareness services” in EU member states. A household energy awareness service is any kind of action or tool to support residents in adopting sustainable energy consuming behaviours. These changes of behaviour relate to daily routines, purchasing and investment behaviours. This manual is for the use of housing companies, municipalities, utilities, NGOs and all those who want to encourage building occupants to save both energy and money by providing energy awareness services.
