Daylighting design: Enhancing energy efficiency and visual quality
Abstract
The relationship between light and design is inseparable. Light reveals form, space, texture and colour - all of which are fundamental architectural considerations. Furthermore, light is essential to carry out most activities in buildings. Whether for aesthetic effect - to create mood or stimulation - or to fulfil functional requirements - for visibility and safety - light can be provided artificially or as daylight. It is evident that the use of artificial light in buildings accounts for a significant proportion of primary energy consumption - it is often the single largest use in the energy balance. By the careful introduction of natural light and the appropriate control of electric light, important energy savings can be achieved, whilst reinstating the role of daylighting in modern architecture. This paper discusses the roles of daylight in architecture; introduces recent research, development and technologies; and presents a number of case study examples to demonstrate the application of technology.
