Additionally, the 2008 EU climate and energy package demands Austria to decrease the greenhouse gas emissions by 16% and increase the share of renewable energy sources by 50% till 2020 (basis 2005). With this requirements in mind, Semergy’s goal is to support ongoing EU and Austrian energy saving initiatives by creating an easy-to-use and end-user-friendly decision support system for the determination of a building’s energy performance and the identification of potential improvements. The basis for the energy performance calculation is the Önorm B8110-6 and the OIB-Richtlinie 6 to determine the heating demand with respect to a building’s heat losses (transmission and ventilation losses) and gains (solar and internal gains), supplemented by additional Önorms (e.g. B8110-5 for climate and building usage parameters). The calculation of the heating energy demand with respect to different heating systems with different energy carrier types is based on the Önorm H5056 to determine the heating technology energy demand (i.e., heat losses) to factor in an estimation of the energy saving potentials of updating an existing heating system. Sustainability information of building products is given the IBO OI3 index values.
