ISO 13790:2008 gives calculation methods for assessment of the annual energy use for space heating and cooling of a residential or a non-residential building, or a part of it, referred to as “the building”. This method includes the calculation of: the heat transfer by transmission and ventilation of the building zone when heated or cooled to constant internal temperature; the contribution of internal and solar heat gains to the building heat balance; the annual energy needs for heating and cooling, to maintain the specified set-point temperatures in the building – latent heat not included; the annual energy use for heating and cooling of the building, using input from the relevant system standards referred to in ISO 13790:2008 and specified in Annex A. ISO 13790:2008 also gives an alternative simple hourly method, using hourly user schedules (such as temperature set-points, ventilation modes or operation schedules of movable solar shading). Procedures are given for the use of more detailed simulation methods to ensure compatibility and consistency between the application and results of the different types of method. ISO 13790:2008 provides, for instance, common rules for the boundary conditions and physical input data irrespective of the calculation approach chosen. ISO 13790:2008 has been developed for buildings that are, or are assumed to be, heated and/or cooled for the thermal comfort of people, but can be used for other types of building or other types of use (e.g. industrial, agricultural, swimming pool), as long as appropriate input data are chosen and the impact of special physical conditions on the accuracy is taken into consideration. The calculation procedures in ISO 13790:2008 are restricted to sensible heating and cooling. The energy use due to humidification is calculated in the relevant standard on the energy performance of ventilation systems, as specified in Annex A; similarly, the energy use due to dehumidification is calculated in the relevant standard on the energy performance of space cooling systems, as specified in Annex A. ISO 13790:2008 is applicable to buildings at the design stage and to existing buildings. The input data directly or indirectly called for by ISO 13790:2008 should be available from the building files or the building itself. If this is not the case, it is explicitly stated at relevant places in ISO 13790:2008 that it may be decided at national level to allow for other sources of information. In this case, the user reports which input data have been used and from which source. Normally, for the assessment of the energy performance for an energy performance certificate, a protocol is defined at national or regional level to specify the type of sources of information and the conditions when they may be applied instead of the full required input.

<p>ISO 13790:2004 gives a simplified calculation method for assessment of the annual energy use for space heating of a residential or a non-residential building, or a part of it, which will be referred to as "the building".</p> <p>It does not apply to buildings with air conditioning systems likely to provide space cooling during the heating season.</p> <p>This method includes the calculation of: the heat losses of the building when heated to constant internal temperature; the annual heat required to maintain the specified set-point temperatures in the building; the annual energy required by the heating system of the building for space heating, using heating system characteristics which are to be found in specific European or International standards, or, by default, in national documents.</p>
Le présent document, basé sur l'ISO 9164:1989, mais plus complet que cette dernière, donnait une méthode de calcul simplifiée : 1) du coefficient de déperditions de bâtiments chauffés à une température uniforme ; 2) de la quantité de chaleur annuelle à fournir dans un bâtiment pour y maintenir des températures intérieures de consigne spécifiées ; 3) la quantité d'énergie annuelle à fournir au système de chauffage d'un bâtiment pour le chauffage des locaux et la production d'eau chaude basée sur une période de calcul mensuelle. Après une complète révision, suite à une première enquête CEN, le présent document a été simplifié pour le rendre d'application plus pratique. La partie relative à la ventilation a, par contre, été développée. Il est destiné à être appliqué aux bâtiments résidentiels (logements) comportant des apports internes relativement faibles et non climatisés.

No specific numerical techniques are imposed by ISO 52017-1:2017.</p> <p>Specific calculation procedures based on the generic calculation procedures of ISO 52017-1:2017 are given in ISO 52016-1. The specific simplifications, assumptions and boundary conditions in ISO 52016-1 are tailored to the respective application areas, such as the energy need for heating and cooling and for humidification and dehumidification, hourly internal temperature, design heating and cooling and humidification and dehumidification load.</p> <p>NOTE Table 1 in the Introduction shows the relative position of ISO 52017-1:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.</p>
