| Summary: | This research focuses on energy reductions from the use of daylighting in residential buildings located in hot and humid climates. The proposed research studied the effectiveness of different daylighting strategies and assessed their performance in enhancing natural lighting in the space without causing excessive heat gain problems in the building. The goal of using effective daylighting strategies is to protect the interior from direct sunlight during the cooling season, and deliver indirect light into the building interior to reduce the need for supplemental lighting. The concern about using daylighting is that, while reducing the solar heat gains, it also reduces the amount of daylight needed to supplement interior lighting. Therefore, the objective of this study is to explore the effectiveness of daylighting strategies that balance the solar heat gain reduction and daylight utilization and result in electrical energy savings in building. The study was performed using a physical scale model for the Daylight Factor studies and the DOE-2 energy simulation computer program for simulating models of a case study Habitat for Humanity house with and without applied daylighting. The case study building was used to represent the typical energy end-use patterns in the single-family residence in hot and humid climates. Illuminance data was measured at different points in the model under actual overcast sky conditions to obtain the Daylight Factors of the proposed daylighting models, which were then compared to the basecase building. The annual energy analysis was conducted using the DOE-2 energy simulation program. Results are reported in terms of the annual heating, cooling, and electrical energy uses with each device in place, as compared to the baseline building. |
