Abstract
  • The problem with using shading devices in shopping malls lies in balancing their aesthetic design with their ability to support energy performance. This study aims to compare the effectiveness of shading devices in commercial buildings, specifically focusing on two shopping malls in Taman Melawati, Kuala Lumpur: Melawati Mall and KL East Mall. The objective is to identify the types of shading devices utilized in these shopping malls and evaluate their impact on glare and aesthetic facades. The research employs a qualitative approach, emphasizing direct observation of the shading devices used on the façades of both malls. The study reveals that Melawati Mall and KL East Mall each employ different shading device designs tailored to their unique architectural features and building orientations. Melawati Mall strategically places fixed overhangs and horizontal louvers according to the building's sun exposure to maximize shading efficiency. In contrast, KL East Mall incorporates a combination of vertical fins and perforated metal screens, designed to provide optimal shading for its glass façades while enhancing the building's aesthetic appeal. The findings indicate the importance of design and pattern in the shading device strategies used on shopping mall façades. The results show the types of shading devices, their locations on the façades, and how their placement addresses glare issues during the morning and evening. In conclusion, designers must carefully consider climate, solar radiation, glare from the sun, building orientation, and the choice of materials on the façade when selecting shading devices. These factors are crucial to ensuring both energy performance and visual appeal in the design of commercial buildings.
