NARM, the National Association of Rooflight Manufacturers has published a new 16 page technical document, entitled ‘An introduction to natural daylight design in domestic properties’.
This is listed as NARM Technical Document 12 (NTD12) and is available for free download from the NARM website.
Prepared by a team from NARM’s highly respected Technical Committee, the new document gives generic information on types of daylight, health and wellbeing, followed by detailed and up-to-date specification information and data.
Until the late 1990s, lighting recommendations were based primarily on lighting needs for vision. In recent years, the lighting community has adopted a broader definition of lighting quality including human needs, architectural integration, and economic constraints. The document addresses these topics in clear language that is accessible by specifiers as well as homeowners wishing to play a role in providing daylighting for their homes.
Practical design advice is offered, with informative layout diagrams designed to help maximise daylight whilst avoiding solar heat build up. There is also a detailed chapter on energy efficiency – a subject that NARM has championed through commissioning of independent analysis over a number of years.
