CEN/TC 371

Energy Performance of Buildings

European Committee

Sector operator: BWSA
Belgian committee: BWSA/E371

CEN/TC 371 ‘Energy performance of buildings’ is concerned with standardization related to the energy performance of buildings (EPB). The TC ensures the development, alignment and maintenance of a coherent set of standards for the determination of the EPB. It does so by (I) developing standards at overarching EPB level and by (II) coordinating the activities of related and specialized TCs that are responsible for the development of EPB standards within their scope, thereby ensuring harmonisation. CEN/TC 371 produced and maintains documents providing guidance and requirements to be met by EPB standards. 1. Developing standards at overarching EPB level The scope of EPB consists of the interrelated energy effects of indoor environmental quality, outdoor climate, thermal properties, heating and cooling systems, domestic hot water, ventilation, lighting, (de)humidification, building automation and control, energy sources and connected energy grid, and related environmental and economic impacts, and not of these topics themselves. CEN/TC 371 focusses on systems’ standards limited to buildings and the direct environment of the building if it effects the energy performance of that building. Product standards and non-EPB parameters are not part of its scope. 2. Coordinating the activities of related and specialized TCs The following specialised TCs are responsible for the development of the specialized standards that together, using a holistic or systematic approach, make up the set of EPB standards. These TCs have the responsibility for subjects on technical issues that belong exclusively to them even if it is an EPB standard. Requirements for indoor environmental quality (IEQ) parameters are fully within the responsibility of the related and specialized CEN/TCs and are not within the scope of this committee. CEN/TC 371 and the TC’s listed below shall refer to each other’s documents to prevent overlap: • CEN/TC 089 ‘Thermal performance of buildings and building components’; • CEN/TC 156 ‘Ventilation for buildings’; • CEN/TC 169 ‘Light and lighting’; • CEN/TC 228 ‘Heating systems and water based cooling systems in buildings’; • CEN/TC 247 ‘Building automation, control and building management’.
