CEN/TC 228
Heating systems and water based cooling systems in buildings

Standardisation of functional requirements for all types of heating systems, including domestic hot water production, water based cooling emission and distribution systems in buildings and powe generation systems in the direct environment of the building. Furthermore standardisation in relation to energy performance of buildings. The work includes: - General performance requirements for heating systems, - General requirements for design of heating systems, water based cooling systems and power generation systems; - Requirements for installation and commissioning, including system tests on the heating and water based cooling system as a whole; - Requirements for preparation of instructions for operation, maintenance and use of heating and water based cooling systems; - Requirements for inspection of heating systems; - Methods for calculation of design heat loads, as basis for sizing of heating equipment; - Methods for calculation of energy use of heating systems, water based cooling systems and power generation systems in the direct environment of the building (e.g. wind power, thermo solar and photovoltaic), including energy economy and environmental impact, as basis for supporting energy performance criteria and/or energy certification of heating systems, water based cooling systems and power generation systems on building or building unit level; - Assessment of energy performance of district heating and cooling systems; - Co-operation with other CEN/TCs (such as CEN/TC 156) responsible for related systems and products in order to establish a common terminology and a common set of technical parameters that can be used for both product declaration and design information. The wind turbines handled by CEN/TC 228 are small plants as they may occur in domestic production and use of electricity in connection with buildings. The same applies to photovoltaic, CEN/TC 228 describes a process by which electrical energy, which is produced by building integrated or additive photovoltaic systems in the direct environment of the building, is determined. Not covered are: - requirements on products such as heating and cooling units, wind power units and photovoltaic units which are in the responsibility of dedicated Technical Committees (such as CEN/TC 57, CEN/TC 109, CEN/TC 113, CEN/TC 130, CEN/TC 182, CEN/TC 312 CLC/TC 82 and CLC/TC 88); - cooling generation systems (covered by CEN/TC 156); - calculation of cooling load (covered by CEN/TC 156).
