Improving daylighting and thermal performance in Sports Hall buildings with Phase Change Materials (PCM)‎ to reduce energy consumption

الملخص EN

The research paper proposes a model for using phase change materials to improve the visual and thermal performance of indoor sports halls, with the goal of achieving maximum natural lighting during the day and improving thermal performance, thus optimizing energy consumption.

this is accomplished by employing (PCM translucent) for window openings and PCM paraffin for wall thermal insulation.

experiments were conducted to determine the best ratio of (WWR%) openings that could be utilized in the northern façade and ceilings to achieve maximum natural lighting during the day using the transparent PCM material and the simulation program to the different widow wall ratios (25,35, and 45%).

the results showed that as the percentages of openings in the wall and ceiling increased, but when they increased 45% of the side effect "light scattering" began to appear, the results showed improved thermal performance by using (PCM paraffin) as a thermal insulator to insulate the southern façade.

comparing the simulation results of the gymnasium spaces before and after development revealed a clear improvement, with the value of daylight improved by 163%, the temperature improved by 27%, the humidity improved by 27%, and solar radiation improved by 70% , energy consumption was reduced by 67% As a result.
