room are practically working in the dark? Academic Kit Cuttle believes he may have an answer: ignore the lighting profession and the daylight factor when it comes to designing inhabitable spaces. Read the thinking behind his argument – and the opposing view of John Mardaljevic – on page 14. Peter Boyce continues the theme, examining the role lighting criteria play in delivering good quality lighting. According to Boyce, the client and designer should have an ambition to achieve more than simply designing a space that avoids complaints from its occupants. Learn more about his ideas on the obstacles and behaviours that can make or break good quality lighting on page 4. And Andrew Bissell explains how the new Priority Schools Building Programme heralds a step change in lighting for schools. Turn to page 8 to find out why Bissell thinks the lighting community is starting to give more credence to daylight and measured weather data than the daylight factor. Carina Bailey, deputy editor

A word from our sponsor...


In the past 12 months LED lighting has gone from being a decorative accessory to becoming the obvious replacement for fluorescent and halogen. With high levels of energy efficiency, reduced carbon output and zero lamp disposals, government regulation continues to support this transition. Within the housing and


hotel sectors, the potential for energy saving is huge, with an 8 Watt LED fixture capable of producing the same light output as a traditional 50W halogen lamp. LED lights also benefit from exceptionally long life, with almost no light loss. In areas requiring greater


light output, the energy saving argument is more

confused. Although LED fittings outperform fluorescent, the main benefits are zero maintenance, better light quality and improved aesthetics. Lamp changing is a significant operating cost for any facilities manager and integrated LED fittings are designed to eliminate lamp replacement, with extended warranties offering added reassurance when specifying LED lighting. An unrecognised benefit of


LED lighting is its tolerance of frequent on and off switching without any deterioration in life expectancy. Daylight compensation and occupancy sensing are therefore opportunities for additional energy saving. The price of LED fixtures is now comparable to


that of traditional light sources, with cost savings and carbon reductions helping to decrease overheads, while reducing the environmental impact of commercial and domestic lighting. In the next 12 months I would


be surprised to see any major project or refurbishment that doesn’t specify LED lighting.
