Design Guidelines for Implementation of Daylighting Strategies in Buildings of Pakistan

Turn on the lights please! Heard this many times? Because we like to see things lit properly and use artificial lights to do that, despite having natural light available for half the day. A well-daylit space connects to the outdoors, providing visual and thermal comfort while maximizing artificial lighting savings and reducing peak energy loads. Daylight offers pleasant indoor environments with better color rendering and alignment with human visual responses compared to artificial light sources. The benefits of daylight on occupant comfort, health, well-being, and productivity are well-documented. Despite these advantages, daylight is not widely integrated into building design due to a lack of information and evaluation tools regarding its suitability and energy-saving potential. This study conducts a systematic literature review to understand existing research and synthesize findings. Literature from large databases was reviewed, focusing on daylight integration. This research aims to present a review of metrics and standards for indoor daylight availability to aid decision-makers. The study concludes with recommendations for implementing and interpreting Daylighting Building Standards for successful daylighting architecture.
