Preliminary estimation about renovation solution

Building envelope:Exterior wall: U0,12 W/(m2K)

Basement wall: U0,17 W/(m2K)Roof: U0,10 W/(m2K)Windows: U0,80 W/(m2K)Basement ceiling: U0,26 W/(m2K)Insulation of loggias  interior heated areaVentilation: balanced ventilation with HR in each apartmentHeating: radiators, thermostats, renovation of heat centreSolar collectors for DHV on roofPV for electricity on facadesMORE-CONNECT engine:in loggia or on roofSlide6
