There is a great deal of research involved in designing zero-energy buildings and engineering systems for them, however, there is little research to determine the amount of heat absorbed by wind flow from the surface of energy efficient and passive houses. The purpose of this scientific work was to evaluate the effect of wind pressure on the surface of a zero-energy building depending on the direction of flow around the air stream. To that end, it was created hollow building model in scale 1:16. Aerodynamic research were carried out in subsonic wind tunnel at Lviv Polytechnic National University.
Because of carrying out a number of experiments, aerodynamic coefficients on the surface of the house, ventilation openings at different angles of airflow, namely, α=0°; 90; 180; 270, to the house were determined. Plots of distribution of aerodynamic coefficients are obtained which allow to choose rational orientation of the house during its design.
