Abstract
At a time when much attention is paid to the problem of energy saving is looking for new technical solutions, among others in the construction industry. At present, searching new solutions is a worldwide trend in creating buildings. Those solutions enable a comfortable use of building structures in harmony with natural environment and ensure reducing energy consumption. Solar chimneys, which facilitate the gravity ventilation by using solar energy, may be a solution to the problem. In hot climates solar chimney has been applied in the process of passive cooling of a building. In temperate zones and cold is used to assist natural ventilation. The problem of the solar chimney is not popular in Poland. Construction in Bydgoszcz two research positions, enabled the analysis of the impact of solar chimneys on the thermal comfort of rooms. This article presents experimental studies on solar chimney located in Poland. The analysis of the flow of air in the room during the day have been measured using two testmodels situated on the 3.1 building of UTP University of Science and Technology at 7 Kaliska street in Bydgoszcz.

The climate inside consists of such elements as: the amount of air supplied into a room that has a proper temperature, humidity and cleanness, and maintaining necessary temperature to feel thermal comfort in a room
Summary
It can be observed that the price of coal, gas, petroleum and electric energy is constantly increasing. In order to reduce this problem, many different solutions are adopted to support the operation of a gravity ventilation Those solutions stimulate the gravity ventilation to work better and, at the same time, improve the microclimate in a room. These are the solutions that do not generate higher costs of facility maintenance, which is of a great importance as far as economic calculation is concerned. Relating to the systems that shape the inner climate in rooms in the summer, current legal articles in “The domestic plan aiming at increasing the number of buildings with low energy consumption” mention exact solutions for eliminating or reducing the power of refrigerating system for air conditioning systems that use refrigerating units. With reference to the use of alternative cooling methods, the aim of this publication is to present a test stand that is a solar chimney and the analysis of carried out research that confirms justified use of the solar chimney in order to increase the air exchange in a room
