ROOFING, CLADDING AND ACCESSORIES LIGHT BENEFITS With health and wellbeing taken into account by just 35% of architects working in the residential sector according to recent research, Val King, chairman of The Rooflight Company, discusses the benefits of maximising natural daylight and ventilation in buildings. Building design can have a huge impact on our health. Throughout our lives, we all spend a large amount of time indoors, away from natural sunlight and a natural air supply. Health and wellbeing is defined by the World Health Organisation (WHO) as a ‘state of complete physical, mental and social wellbeing’. The UK Green Building Council (UKGBC) also includes social, psychological and physical factors in its definition. 46 BUILDING PRODUCTS | DECEMBER 2017 A recent study carried out by research agency, Cadvantage, surveyed 150 architects and found that, of its sample, only 11% could correctly define what health and wellbeing means in building design. The research identified that health and wellbeing was taken into consideration by only 59% of the architects working on education buildings, 57% of those designing healthcare buildings, 48% of those working on office spaces, 44% of those designing retail spaces and most worrying of all, 35% of those working in the residential sector. It is widely accepted that natural light and ventilation can vastly improve health, concentration levels and performance, so these findings will not be well received by the UKGBC or other organisations such as the National Association of Rooflight Manufacturers (NARM), which regularly promote the health and wellbeing benefits of light from above in building design. The UKGBC believes that generous access to daylight, as well as a supply of natural ventilation, should be part of the design considerations for health and wellbeing. However, Cadvantage has also revealed that 43% of the architects surveyed felt that the support they receive from manufacturers is inadequate when they are specifying products that meet health and wellbeing needs. According to NARM, daylight is an essential natural asset. There is a growing body of evidence to suggest that buildings enjoying high levels of natural light are literally more successful than those more reliant on artificial light. In all environments, the eye and brain functions respond better to natural light, so people perform better, while passive solar gain can reduce energy costs. It’s clear from the UKGBC, WHO and NARM that maximising natural daylight and ventilation in buildings is key to improving the health and wellbeing of the UK population. One solution is to specify rooflights on a design scheme. Rooflights can flood up to three times more natural light into a space than a vertical window of an equivalent size to truly maximise natural light from above. www.therooflightcompany.co.uk
