Theoretical Substantiation of the Strategy of Major Renovation of Collective Housing Buildings in the Urban Area

Summary/Abstract: The new social phenomenon of associations of people converted into prosumers (on grid) is analyzed in terms of energy efficiency. The consequences of promoting the quality of prosumers for CRB (current representative building) (especially in urban areas) and for RRB (renovated representative buildings) (which have benefited from thermal renovation) are analyzed. The real purpose of the associations is to reduce the costs of energy utilities (and not only) and to benefit to a small extent from the electricity consumed in the building. It is demonstrated, on the basis of dynamic simulation of the energy response of buildings to climate and anthropogenic requirements, that converting CRB buildings exclusively into prosumers with no other purpose than minimizing utility costs keeps the energy and environmental performance of buildings away from the quality of nZEB buildings. On the other hand, the transformation of renovated RRB into nZEB buildings is ensured by equipping them with photovoltaic solar panels and thus acquiring the quality of prosumer.
