This document specifies: - a structured list of control, building automation and technical building management functions which contribute to the energy performance of buildings; functions have been categorized and structured according to building disciplines and building automation and control (BAC); - a method to define minimum requirements or any specification regarding the control, building automation and technical building management functions contributing to energy efficiency of a building to be implemented in building of different complexities; - a factor-based method to get a first estimation of the effect of these functions on typical buildings types and use profiles; - detailed methods to assess the effect of these functions on a given building. This document has been prepared by Technical Committee ISO/TC 205 "Building environment design" in collaboration with Technical Committee CEN/TC 247 "Building automation, controls and building management", the secretariat of which is held by SNV (Switzerland).The responsible committee for the German contribution is Working Committee NA 041-05-03 AA "Energieeffizienz in Gebäuden - Auswirkungen der Gebäudeautomation und des Gebäudemanagements" ("Energy efficiency of buildings - Impact of building automation and building management") at DIN Standards Committee Heating and Ventilation Technology (NHRS).
