Abstract

The paper presents a comparative analysis and an attempt to determine which of the analyzed types of ventilation is the most advantageous for single-family buildings. At first basic information on ventilation systems used in residential buildings is presented. Attempts have been made to bring its contemporary problems, resulting mainly from the lack of sufficient fresh air supply. The second part of the article is devoted to the comparative analysis of gravitational and mechanical ventilation with heat recovery system taking into account 3 criteria: investment and operating costs, quality of the air supplied to rooms and energy demand for heating purposes. The subject of the research was the design of a single-family building with an area of 185 m2. The paper uses the author’s cost estimates of the construction of ventilation systems valid for 2018, measurement data from the provincial Inspectorate of Environmental Protection in Poznan as well as the methodology of determining the energy performance of buildings.
