This European standard defines a method for the performance assessment of building-integrated cogeneration units by the calculation of the electricity production, useful heat output and recoverable losses. Such units are commonly known as micro or small scale cogeneration, or micro or small scale CHP. A building-integrated cogeneration, is a cogeneration unit installed to supply space heating, domestic hot water and possibly cooling within a building. It could operate as the only heating/cooling appliance of the building or in combination with other heat generators, such as boilers or electrical chillers. Unlike district heating systems, where heat and electricity are generated at central plants and transmitted through networks to a number of remote buildings, a building-integrated cogeneration unit produces useful heat for uses within the building. The electricity produced by the integrated cogeneration unit may be used within the building or may be exported. This standard deals with heat generators for heating or for combined domestic hot water and heating services. The calculation is based on the performance characteristics of the units, defined in product standards, and on operation conditions such the needed heat output. Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000 1. NOTE 1 In prCEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation. NOTE 2 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
