Abstract
Architects and designers are increasingly interested in employing dynamic façades in contemporary office buildings. One of the dynamic facade types, which is widely used is a solar screen and they affect the indoor environment. This study evaluates the effect of a solar screen across a range of perforation ratios and its distance to the building on energy utilization, natural ventilation, indoor air temperature, and CO2 concentration in contemporary office buildings. Results demonstrate that dynamic solar screens have a promising positive impact on reducing energy consumption while improving indoor air quality. When these screens are in a closed state, they can reduce indoor air temperature up to 1°C and reduce energy consumption up to 60% in their most optimized state. Furthermore, the study’s results show that the dynamic solar screens impact airflow inside the office space based on their different states (open, semi-open, or closed).
