ABSTRACT

This paper investigates the requirements of daylight in conjunction with sustainable building design and the challenges of assessing daylighting in buildings. Daylight is an available resource that adds value both architecturally and economically. Qualitative daylighting design has the capacity to increase user satisfaction and productivity. Moreover, when consciously exploited and used together with energy-efficient lighting and controls, daylighting can reduce energy consumed by electric lighting by up to 70% with immediate results on decreasing overall building energy use. Successfully designing daylighting into buildings in a way that leads to high levels of visual comfort and also reducing energy use of the building is a complex and challenging process, demanding daylighting considerations at all stages of the building design process, from site planning through architectural, interior, and lighting design evaluation, to the conscious design of the building elements such as windows and skylights, which admit daylight in buildings. Investment in daylight generates a large return in term of considerable reductions in energy consumption and CO2 emissions.
