Abstract

This study investigates the impact of roller blinds as an energy-saving strategy in a subtropical climate. Lighting control experiments were performed on west-facing and south-facing windows in the Subtropical Performance-Testbed for Innovative eNergy Research in Buildings Laboratory (SPINLab). This study accepts sunlight below 8000 lux and requires the indoor lighting of at least a reading of 500 lux. For the west-facing window experiment, the curtain energy-saving strategy implemented in this study resulted in 10% less energy consumption for air-conditioning and saved 90% of the lighting power consumption of the west facing window building. For the south-facing window experiment, we found that sunlight can fully supplement the lighting without adjusting the roller blinds because the window opening is different from the sunlight direction. In addition, the significant heat flux difference between the west-facing and south-facing windows experiments is also reflected in the energy consumption of the air conditioners.
