Abstract

The performance of Venetian blinds can be improved by adopting split blinds by which the slat angle in the upper and lower part of the blinds can be separately adjusted. In this study, the impact of the split blinds on the lighting/thermal environment and energy consumption was investigated through field measurement, occupant survey and energy simulation. Four different adjustment methods were evaluated: Case 1 (No blind), Case 2 (All slats open), Case 3 (Upper slats open, lower slats closed), and Case 4 (All slats closed). The evaluation result of lighting environment showed that Case 3 is effective in preventing the excessive illuminance level as well as glare in the winter season, while Case 2 or 3 is suitable for the summer season because the high solar altitude reduces the transmitted solar energy, which leads to the reduced glare risks. The evaluation result of thermal environment revealed that acceptable thermal comfort can be achieved by Case 2 or 3 in the winter season, and Cases 2 to 4 in the summer season. Energy simulation results showed that the overall energy consumption (heating, cooling and lighting energy) can be minimized by applying Case 3, by which the energy consumption can be reduced by 6.2% compared to Case 1.
