Providing lighting accounts for around 15% of the energy bill in most homes, and around 25% in commercial buildings. It is supplied by electrical power plants using fossil fuels, and is responsible for a significant percentage of carbon dioxide emissions, a leading cause of global climate change. Because of this, the building industry has targeted lighting as a key element in sustainable design, and there is now a global movement to develop and implement lighting solutions that meet people’s needs and concerns, and address environmental regulations.
The most sustainable lighting is natural daylight and is a free renewable resource. Architects should maximise natural light while maintaining indoor temperature regulation and reducing direct light glare. The placement of windows, skylights, light shafts, atriums and translucent panels all contributes to effective daylighting design.
Sunlight Transportation System
An emerging new technology is that of sunlight transportation. Natural sunlight is collected on roof panels and transported into a building via fibre optic cables for distances up to 15 metres. These sunlight-piping systems can be used in combination with solar panels to integrate natural and artificial light systems, so that there is always light available.
