IEA EBC Annex 67

The foreseen large deployment of renewable energy sources may seriously affect the stability of energy grids. It will be necessary to control energy consumption to match instantaneous energy production. The built-in Energy Flexibility in buildings may be utilized for stabilizing the energy grids, allowing for a larger roll out of renewable technologies.

The Energy Flexibility of a building is the ability to manage its energy demand and generation according to local climate conditions, user needs, and grid requirements. Energy Flexibility of buildings will thus allow for demand side management and load control and thereby demand response based of the requirements of the surrounding grids.

Currently there is no overview on how much Energy Flexibility different building types and their usage may be able to offer to future energy systems. The aim of Annex 67 is thus to increase knowledge on and demonstrate the Energy Flexibility buildings can provide for the energy grids, and to identify critical aspects and possible solutions to manage this.

In-depth knowledge of the Energy Flexibility that buildings may provide is important for the design of future Smart Energy systems and buildings. The knowledge is important for the utilities, companies and for policy mangers and government entities.
