BS EN 15316 discusses the energy performance of buildings. BS EN 15316-4-4 belongs to BS EN 15316 multi-series and discusses heat generation systems, building-integrated cogeneration systems, Module M8-3-4, M8-8-4, M8-11-4.
BS EN 15316-4-4 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.
BS EN 15316-4-4 on the energy performance of buildings (heat generation systems, building-integrated cogeneration systems) is useful for:
BS EN 15316-4-4 is part of a series of standards aiming at international harmonization of the methodology for the assessment of the energy performance of buildings, called the “set of EPB standards.
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 several 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 maybe exported.
BS EN 15316-4-4 provides you with a method for calculation of the system energy losses and the energy performance of building-integrated cogeneration systems. The calculation is based on the performance characteristics of the units, defined in product standards, and on operation conditions such as the needed heat output.
