Barrett, Richard. "Natural Lighting of Deep Architectural Space: The Perception of New Zealand Architects," in ArchNet-IJAR: International Journal of Architectural Research, vol. 2, issue 2 (2008).
The paper considers aspects of a survey carried out amongst a group of registered New Zealand architects in order to establish their knowledge and experience in using core-daylighting systems and methods (Barrett, 2003). Core-daylighting comprises systems and methods for bringing natural light into deep architectural space where conventional methods (such as windows and skylights) cannot readily be used. Examples of these methods are: atria (Matusiak, 1998), sun tracking heliostats, sun and light pipes, light scoops, Fresnel lenses, anidolic zenithal systems, prismatic daylight systems, light shelves,tapping mirrors, light reflectors and louvres (Littlefair, 1991, 1996 & 2000), lightwells, internal courts (Lam, 1986), fibre optic cable (Kay,1999), and other systems for light re-direction.
The survey was carried out using a questionnaire as described below (Survey Methods). The findings were analysed, resulting in a clear indication that the respondents were not especially experienced or knowledgeable, and a majority felt this to be an area of their skill base in need of development. Whilst the survey was strictly intended to gather quantitative material, respondents were invited to comment freely as they progressed through to completion of the questionnaire. This paper draws on this qualitative data as an insight into several areas, including the attitudes of respondents towards their clients when making decisions about designing buildings for natural daylighting.
