Building Thermal, Lighting, and Acoustics Modeling
Facades have a significant impact on energy performance, especially in high-rise buildings. As the population grows, high-rise buildings gain inevitable importance since they are compact and can enhance land use. Glass facades are widely used in modern tall buildings for their aesthetics. However, extensive glass curtain wall can cause high energy consumption due to excess heat gains in warm-season or thermal loss in a cold period. Findings by Elarga et al. (2015) showed that double skin facade (DSF) was an efficient option to overcome the problem mentioned above. The first DSF was designed in Germany to prevent cold weather and strong winds. Thus, people will probably doubt the possibility of applying the DSF system in hot climates. However, since architects welcome DSF du
