In summer, when external temperatures often rise above 30°C, and when we have many sunny hours in Slovenia, indoor temperatures can quickly become uncomfortable. In business premises, such conditions reduce work efficiency, while in private spaces, they significantly diminish the quality of living. Modern architecture has revolved around glass facades and large open volumes for many years, which provides partial passive heating through the winter but poses a significant challenge for shading and cooling during the summer months. Therefore, building cooling is becoming increasingly important. Additionally, the rising standard of living demands thermal comfort. Let’s see what thermal comfort means. A space is considered thermally comfortable when the room temperature in summer is below 28°C and above 20°C. The comfortable minimum surface temperature is between 21°C and 26°C.
