Reference Building Approach Combined with Dynamic Simulation in Designing nZEBs

The building energy performance requirements in the regulations are usually expressed by means of a fixed value or a variable value defined through a formula or the notional reference building approach. The aim of the article is to enhance the application of the notional reference building approach in the energy performance legislation. To this purpose, a detailed dynamic simulation is performed on an Italian residential nZEB located in two different climatic zones. The paper highlights the need of more detailed specifications of the reference parameters in the notional reference building, especially when dynamic simulation is performed.
