This European Standard covers energy performance calculation of mechanical ventilation systems with integrated heating/cooling generation, including domestic hot water production, using a monthly or seasonal calculation interval or a bin method. It takes into account the generation (air handling unit) and distribution (duct system) parts. It does not cover the emission part (calculation of the required volume flow rates and/or supply air conditions), which is covered in the M5-5 standard. It does not include humidification and dehumidification. This method is focussed on small, packaged ventilation systems, typically used in residential buildings, although the application is not restricted on the basis of building or space use type. A calculation method for mechanical ventilation and air conditioning systems, including humidification and dehumidification, using an hourly calculation interval or a bin method, is provided in a separate standard, EN 16798-5-1. This standard is part of the DIN EN ISO 52000 series of standards and has been prepared under the EPBD mandate M/480. In Germany, the Directive on the energy performance of buildings (2010/31/EU) of the European Parliament and the European Council is primarily implemented by national energy conservation law. National energy conservation law refers to dated national and European Standards and national prestandards that have been specified to be implemented in Germany. In Germany, the application of this standard in connection with national energy conservation law is defined by provisions in this law. Provisions of German energy conservation law cannot be systematically fully and identically implemented with the set of standards under the EPBD mandate M/480 and the therein referenced International and European Standards. When applying the standards of the mandate, accordance with German energy conservation law cannot be achieved, whether in terms of the procedure, the result, or assessment of the result. Currently, the set of standards of the EPBD mandate M/480 is not applicable for the purposes of German energy conservation law, even if references to national regulations in the respective national annexes are taken into consideration. The responsible German committee is NA 041-05-02 AA "Energetische Bewertung von raumluft- und klimakältetechnischen Anlagen" ("Energy efficiency of ventilation/air conditioning and refrigeration systems") at DIN Standards Committee Heating and Ventilation Technology and their Safety (NHRS).
