Furthermore, the omni-directional Monodraught Sunpipe Diamond domes capture light from all directions, and the resulting diffused light bounces down into the wards or rooms below. To quote an example, a 300mm diameter Sunpipe provides reading-quality diffused light over a 3 metre distance from the ceiling and to an area of approximately 9 square metres.


emissions by 20% over the next five years, and the cost of electricity expected to increase by up to 20%, it’s no surprise that natural and sustainable alternatives such as Sunpipes are being specified as an alternative to energy-hungry electric lighting in almost every area of our daily lives.


Besides their proven contribution to patient recovery, Sunpipe natural lighting systems are also a most innovative solution to the problem of our growing energy consumption, since they eliminate the need to use electric lighting during daylight hours. With government committed to reducing energy consumption and CO2


considerable health benefits experienced due to the much improved patient environment.


At least 75% of electricity costs used for lighting can be saved during daytime where Sunpipes are used to replace electric lighting during daylight hours. Monodraught estimates that cost savings can result in a 5 to 6 year pay-back period in addition to the


As well as the on-going cost savings from their energy-free operation, Sunpipes also require little or no maintenance outside the building, thus saving even more on costs. The unbreakable diamond shaped dome is made of 4mm UV-protected polycarbonate and is designed to ensure that dust and dirt is washed off naturally by rainwater. Internal ceiling diffusers require no maintenance. The Sunpipes’ highly effective sealing system prevents dust, dirt, rain, condensation and heat loss, and the units are guaranteed for 10 years with an expected lifetime of 35 years. The installation and application of Sunpipes is extremely flexible as there is virtually no limit to the length or size of Sunpipe that can be installed. Using a combination of elbows and connections, natural daylight can be reflected horizontally or vertically with an incremental loss of intensity of approximately 3% per metre length. This enables Sunpipes to take light wherever it is required, even into basements. The range of ten different size models is fully supported by the Monodraught design and installation service.
