Abstract:

Establishing the energy performance of residential buildings in accordance with DIN V 18599.

In accordance with EnEV 2009 (Energy Conservation Regulations), it is permitted to calculate the energy performance of residential buildings on the basis of the new DIN V 18599 calculation standard or the older DIN V 4108-6 regulations in combination with DIN V 4701-10. As a rule, calculations carried out in accordance with DIN V 18599 lead to higher primary and final energy demand. This is in part due to less favourable input parameters (room temperature, internal gains, demand for domestic hot water, etc.) but in general, it is mostly due to a significantly less favourable evaluation of services installations when using standard values. Likewise, the permitted primary energy demand of the reference building is significantly higher in most cases when assessed under DIN V 18599, and may even reach the level of the old EnEV 2007, depending on how the calculations are carried out. For the future it would be desirable to modify the calculation methods. This article contains comparative calculations for theoretical residential buildings which also allow a quantitative assessment of the differences in standard cases. It becomes clear that when equivalent input parameters are used and the services installations parameters are defined more precisely, the calculation results are less divergent. With a view to a simplified and yet practice-orientated method for calculating the energy performance of standard residential buildings, it is possible to use the calculation method of DIN V 4108-6 in combination with DIN V 4701-10. Calculating the energy performance of standard residential buildings in accordance with this standard provides a simple and yet reliable method. For buildings with cooling or more complex services installations, DIN V 18599 can be used. It is recommended that future legislation allow the option of choice for residential buildings.
