Relationship between building technologies, energy performance and occupancy in domestic buildings

Abstract

Building regulations have been updated to improve the energy performance of buildings. However, research has shown large differences between expected and actual energy performance of buildings. The differences have been attributed partially to occupant behaviour. Occupants have a large influence on the actual performance of buildings, creating uncertainties related to the actual energy savings, payback periods for low carbon technologies, and actual comfort in the buildings. This section explores the influence that building occupants have on the actual performance of domestic buildings and the consequences in the development of new and renovated low and zero energy housing. Monitoring building performance before and after renovation for retrofit projects, and monitoring building performance in experimental Living Labs and after the occupancy of buildings are discussed as potential solutions for occupancy uncertainties.
