6 pren :2015 (E) NEN-EN :2015 Ontw. Introduction This draft Standard is part of a series of standards aiming at international harmonization of the methodology for the assessment of the energy performance of buildings, called EPB set of standards. As part of the EPB set of standards it complies with the requirements for the set of basic EPB documents (pren 15603, CEN/TS and CEN/TS (see [3] and [2]) developed under a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/480), and supports essential requirements of EU Directive 2010/31/EU on the energy performance of buildings (EPBD). Where appropriate, the method(s) in each of the EPB standards may provide simplified procedures and/or default values as alternative options. Without further specification, these simplified procedures and/or default values may be used without restricting criteria. NOTE For instance because these are conservative procedures or values. The term 'default values' should not be confused with 'informative values'. If the values are given in the normative part of the standard, they are normative values. See also next options. In other cases, these simplified procedures and/or default values may be intended to be used only for situations where there is limited information. This may be the case in existing buildings with limited possibilities to acquire all input data. In particular when the EPB set of standards is used in the context of national or regional building regulations, specific criteria when the simplified method and/or default data are allowed, may be given at national or regional level, following the template in Annex A. Annex B provides (informative) default choices. TC 156 deals with ventilation and air conditioning systems in buildings. Subjects covered by TC 156 are: a) energy performance calculation for ventilation, air conditioning and cooling systems; b) inspection of ventilation and air conditioning systems; This standard specifies the method and the boundary conditions for the calculation of the design cooling load, including latent load, as a basis for the dimensioning of equipment on zone level and on central level for cooling and dehumidification. It specifies also the methods and conditions for the calculation of the humidification load. The method given for the sensible cooling load can also be used for the calculation of the design heat load as an alternative to the simplified method given in pren This is intended especially for the cases where the cooling load calculation needs to be done (i.e. when cooling is necessary) and/or an hourly calculation is used for the energy needs calculation. The principle idea is that there is only one method needed for load and energy calculations for heating and cooling in case of an hourly calculation interval. This draft Standard replaces EN 15243:2007, Clauses 10 and 11. For the detailed description of the calculation method, it refers to pren ISO The result is also of possible use for the checking of the appropriate sizing of the equipment at the occasion of inspections. 4
