Daylighting Evaluation and Retrofit Strategies: A Simulation-Based Approach to Optimise the Artificial Lighting Consumption
Daylighting plays a major role in the design of lecture halls. Architects and designers take advantage of daylight in lecture halls to enhance visual comfort and energy efficiency by using daylighting simulation tools. Daylight simulations provide with the ability to compare many design parameters and optimise design alternatives to promote visual comfort and energy efficiency. Still, daylight is not commonly combined with the artificial lighting in buildings as there is a lack of information and documentation on daylighting simulation tools to assess the energy-saving potential in buildings. This study aims to bridge the gap between the use of daylighting simulation tools and evaluating the energy-saving potential of daylighting in buildings by using a single objective optimisation approach. Twelve lecture halls were selected, and five retrofitting strategies were analysed to enhance the daylighting performance and optimise the artificial lighting consumption of the lecture halls. The simulation results showed 58–95% energy savings after applying the retrofitting strategies. Similarly, the daylight autonomy increased from 40 to 89% for lecture hall G5 and 14 to 51% for lecture hall G12. The DA was found as a good performance indicator and showed a positive correlation with energy savings.
