Abstract

This article calculates horizontal and vertical heat and moisture fluxes in the wall based on measurements of temperature and relative humidity in the building wall. It was a basement wall that was close to the ground on one side and the basement ceiling on the other, which increased the difficulty in problem simulation. The brick material from the wall was also analyzed under an electron microscope and its elemental composition was determined using the EDX (Energy Dispersive X-ray spectroscopy) method. The brick had a relatively uniform elemental composition apart from several variations in calcium content. Monthly, daily, and hourly heat and moisture fluxes were determined. The tested wall was characterized by low humidity, and the values obtained of the moisture fluxes confirmed this. The maximum recorded relative humidity inside the wall is 57.89%, and the minimum is 43.99%. The effect of buffering moisture by brick material was noticed. Vertical streams of water vapor were found to be important in the moisture balance of the tested partition. The maximum heat flux through the tested wall area in August was 0.06 W, and the minimum in January was −0.2 W. The maximum moisture flux in August was 5 × 10 −11 kg/s, and the minimum in January was −5 × 10 −11 kg/s.
