What is BS EN 17037 about?
BS EN 17037 discusses daylight in buildings. BS EN 17037 specifies elements for achieving, by means of natural light, an adequate subjective impression of lightness indoors, and for providing an adequate view out.
In addition, recommendations for the duration of sunshine exposure within occupied rooms are given. BS EN 17037 applies to all spaces that may be regularly occupied by people for extended periods except where daylighting is contrary to the nature and role of the actual work done.
Note: The specification of lighting requirements for humans in indoor workplaces including visual tasks are given in EN 12464-1 and are not part of BS EN 17037.
Who is BS EN 17037 for?
BS EN 17037 on daylight in buildings is useful for:
- Architects
- Interior Designers
- Civil Engineers
- Builders
Why should you use BS EN 17037?
Daylight should be a significant source of illumination for all spaces with daylight opening(s). Daylight is strongly favoured by building occupants to adequately illuminate the indoor surfaces, and to save energy for electrical lighting. A daylight opening can also provide exposure to sunlight indoors, which is important, for example, in dwellings, hospital wards and nurseries. In a space, where activities comparable to reading, writing, or using display devices are carried out, a shading device should be provided to reduce visual discomfort.
BS EN 17037 encourages building designers to assess and ensure successfully daylit spaces. BS EN 17037 also allows building designers and developers to target ambitions with respect to daylighting, as well as addressing other issues related to daylight design, such as view out, protection against glare, and exposure to sunlight.
BS EN 17037 gives information on how to use daylighting to provide lighting within interiors, and how to limit glare. BS EN 17037 defines metrics used for the evaluation of daylighting conditions and gives principles of calculation and verification. These principles allow addressing the issue of variability of daylight over the days and the year
