Daylighting in High-Rise Office Buildings: A Comprehensive Review

Abstract

This article is a detailed review of the significance of daylighting in high-rise office buildings and its importance to the energy performance, visual comfort and productivity of building occupants. Due to increased urbanization globally, high-rise buildings are becoming prevalent in cities, the need for sustainable design approaches, maximize the use of daylight, eliminating glare and increase productivity. Historical background and overview of day lighting systems are discussed, as well as the current techniques and new technologies for passive and active daylight systems. The article also treats some daylighting problems related to buildings, such as glare, regulatory compliance, daylight deprivation, non-uniform daylight distribution. Case studies of projects implemented with exceptional daylighting are introduced. Significant findings on integrating new technologies, self-sufficient buildings, adaptive shade, and the impact of layout in a space to achieve the desired daylighting were also discussed. The potential impact of green rating systems such as LEED and WELL on sustainable daylighting is also highlighted in the review. The future of day lighting with innovative dynamic materials such as electrochromic glass, and climate responsive controls are also discussed to provide a balance between energy savings, productivity and aesthetics.
