Determination of reference values for energy systems in buildings
In order to correct and specify some of the inputs to the evaluation of the energy performance of buildings (EPB), SEVEn’s research team, initiated by the MIT, defined the new values of so-called guideline numbers for the area of technical building equipment (TBE). The guideline numbers are essentially reference parameters of the efficiency and energy consumption of different types of TBE ( from heat sources through lighting to ventilation and air conditioning), which were as input variables in the model calculations of EPB, if the specific values of a given project are unknown. The outputs of this project should be reflected in the intended amendment to Decree No. 148/2007 Coll., on the energy performance of buildings, which currently lists some of this data (incorrectly).
