Standardisation of functional requirements for all types of heating systems in buildings, including domestic hot water production. The work includes:: - General performance requirements for heating systems, considered as a whole and taking into account work already being done in other CEN/TCs; - General requirements for design of heating systems; - Requirements for installation and commissioning, including tests on the heating system as a whole; - Requirements for preparation of instructions for operation and maintenance; - Methods for calculation of design heat loads, as basis for sizing of heat emitters and heat generators; - Methods for calculation of energy requirements of heating systems, including energy economy and environmental impact, as basis for supporting energy performance criteria and/or energy labelling of heating systems; - Co-operation with other CEN/TCs responsible for related systems and products in order to establish a common terminology and a common set of technical parameters.
