Daylighting characterstics of existing double-skin façade office buildings
Highlights ► The aim of this paper is to evaluate the daylighting characteristics of 12 existing DSF office buildings. ► Protocol is: south-facing, overcast condition, implemented outdoor illuminance: 19,000lx, 12,000lx, 6000lx. ► DSF models fail to meet the standard indoor illuminance requirement of 200lx until 75% of the office space. ► In this study, the maximum percentage of the office space covered with at least 200lx is 68%. ► DSF systems from subtropical climates show the best daylighting characteristics among the 12 models.
Abstract Double-skin façade (DSF) buildings have been developed and used in both new and renovated buildings to increase human comfort and decrease energy consumption. Daylighting in DSF buildings has received less attention compared ventilation strategies. This paper aims to evaluate the daylighting characteristics of 12 existing DSF systems that are exposed to different climates by using the IES simulation software. The protocol was applied to south-facing models under overcast sky conditions and was implemented under different outdoor illuminance. Different designs of DSF systems significantly affect the indoor illuminance values inside the office. At the office entrance, the indoor illuminance values are free of glare. All DSF models fail to meet the standard indoor illuminance requirement of at least 200lx within 75% of the office space. Among all the DSF models, the percentage of the office space covered with at least 200lx are found in the range of 40–68%, 13–52%, and 5–30% at an outdoor illuminance of (19,000, 12,000, and 6000)lx, respectively. At an outdoor illuminance of 19,000lx, the studied DSF systems from subtropical climates show the best daylighting characteristics and are potential subjects for further optimization. Based on the assumptions of this case study, daylighting analysis shows that the existing 12 DSF systems do not follow daylighting strategies.
