Airtightness test of single-family building and calculation result of the energy need for heating in Polish conditions

Abstract

The article presents results of air permeability measurements carried out for envelopes of two entire typical single-family residential buildings and separately for envelopes of garages and residential zones of these buildings. The effect of taking into account separate air permeability measurements of building zones on the calculation results of infiltration heat losses and on the energy need for heating is analysed. The calculation results obtained in this way are then compared to calculation results obtained in the case of air permeability measurements of the entire building envelope.
