Effect of Refurbished Thermal Insulation of Exterior Partitions in a Building on the Primary Energy and the Air Pollutant Emission Factors

The paper contains an analysis of a multi-flat building located in Lębork. The calculations made for the existing building as required to issue an energy performance certificate demonstrated its high energy consumption. Renovation of the thermal insulation of the building was simulated, including all partitions enclosing rooms with regulated temperature, independent from the outdoor environment, and other unheated rooms. The effect of the thermal insulation renovation on the Primary Energy Factor and the Air Pollutant Emission Factor was tested. It was proven that the analyzed refurbishment of thermal insulation was insufficient to fulfill the reference value of primary non-renewable energy input, which would ensure considerable savings on costs (amounts of fuels) of heating.
