The reduction factor for heating with unoccupied periods a samz,apk shall be calculated by using the following formula:. Pbn data for assessing the annual energy use for heating and cooling. The loss utilisation factor shall be determined regardless of the cooling system features, assuming that the temperature is fully controlled and is flexible. Partitioning of a building into several parts shall be necessary, if all of the following conditions refer to the building:.

One of the following methods shall be used lbm calculating the energy balance of a building:. Classification of building constructions. If there are unoccupied heating periods and the provisions referred to in Sub-chapter 5. There was a problem providing the content you requested Such internal heat sources like the number of people and duration of their presence in the building shall be assessed by surveying the building, or obtained from the building owner or manager.

Gross calorific values of fuel be determined by using the net calorific coefficients of fuel, multiplying them by the conversion coefficients, which are specified in Table 1 of this Annex. Primary energy factor for the part of non-renewable energy resources f p. It shall be determined on the basis of measurements obtained during at least one month.
