Environmental Legislation, Multilateral Relations and Funding Opportunities
As of 1.1.2023, a legal obligation under Decree No. 264/2020 Coll., Section 4, point 1 and Section 12 to calculate the total delivered energy for buildings with cooling, humidity adjustment and/or electricity generation by a maximum hourly step has been established in the Czech Republic. The current monthly calculations represented stationary thermal balances of losses and gains. The new hourly calculation is a dynamic model. The accuracy of the model increases significantly based on the solution of the differential equations of heat conduction of thermal inertia of the structures. This increases the accuracy of the modelling of the energy performance of the buildings and it is questionable what impact this will have on the evaluation of PENB.
