Abstract

This paper describes part of a research programme on energy consumption in the Polish building sector. The work, carried out from 1980 to 1985, aimed at developing methods for measuring air flows and their influence on heat consumption in typical Polish dwelling houses. It began by establishing both experimental and theoretical methods to determine air flows in buildings. The basic measurements were done in a large number of buildings characteristic of the products of the Polish building industry and located in the Silesia region; both single-family housing and eighteen-storey apartment blocks were considered. The basic aims were to define air flow mechanisms and estimate the influence of air flow on heat consumption. The results verified previous theoretical models. The paper begins by presenting and comparing results of measurements in existing buildings. Theoretical methods are then presented, including the limitation of tightening building envelopes. The choice of ventilation systems with regard to the thermal balance of buildings is discussed.
