Influence of Renewable Energy Sources on the Energy Balance in Urban Areas Reconfigured using the nZEB Energy Atlas Tool

Considering the climate change, the medium and long-term energy objectives of the European Union, regarding climate neutrality require significant reductions in energy consumption and implicitly in CO2 emissions related to the exploitation of buildings, and at the same time the promotion of energy production technologies from renewable source; the building envelope can become the support for the placement of these technologies both in the case of new constructions and in major energy renovation projects. The tools used for the purpose of sustainable urban planning with the objective of promoting new buildings with nearly-zero energy consumption but also with reference to the energetic reconfiguration of the existing built stock, such as the nZEB Urban Energy Atlas (Izabella Marin Lazăr 2022) include the possibility simulation in accordance with the proposed intervention scenarios and specific climatic conditions of the amount of energy from renewable sources that can be produced on site and the contribution of these sources to the energy balance of the urban area.
