Characterization of Energy Flexibility in Buildings
Published:
Energy flexibility represents a key building feature for the future energy systems, where the deployment of renewable energies will increase and the possibility to adapt the energy loads according to the requirements of the grid will be needed. Nevertheless, despite the given attention, a uniform understanding and a commonly accepted definition is still not in place for this building concept. The lack of a clear international framework for the requirements and properties of energy flexible buildings leads to numerous definitions that are being developed in parallel and are applied in the context of specific case studies when evaluating and/or quantifying energy flexibility. In this regard, the report aims to provide a unique and shared vision about energy flexibility, starting from the adoption of a common definition and terminology and from the analysis of the indicators currently available in literature than can be used for quantifying flexibility. According to these first achievements, a common methodology for quantifying and labelling energy flexibility has been defined and tested, in order to complete the general framework on energy flexibility.
