For increase in energy efficiency of the building we propose to install photovoltaics on the roof and south facing façade with capacity of 45k Wp, heat pumps for utilization of waste heat from the building's sewage system and waste heat from ventilation shafts with total capacity of 50 kWp, external window shading for east, west and south facing façades, green roof and ceiling cooling for apartment units. The complex renovation represents a positive benefit not only from the user, energy and environmental point of view, but also economical.
