Abstract :
Making daylight more available in buildings is highly desirable, not only for reasons of energy-efficiency, but also for improvement of
occupants’ health and well-being. Core-daylighting, that is daylight provision in areas situated at considerable distances from fac ades
and windows, is currently one of the main challenges in sustainable building design. Anidolic Daylighting Systems (ADSs) are one very
promising technology in the field of core-daylighting, but commercial solutions that are not only well-performing but also financially
competitive are not yet widely available. This article presents results of parametric studies on Anidolic Integrated Ceilings (AICs), a special
type of ADS, for identification of main influencing factors. The article describes a reliable method for simulating ADS and AIC
performance under given sky conditions. Various simulation results for the example location Singapore are discussed in detail, it is concluded
that the main influencing factors are coating material, system dimensions and external obstruction, and those influencing factors’
potential impacts are quantified. It is shown that AIC overall efficiencies can reach up to almost 50% in Singapore. The essentially new
results presented in this article can be of great help to architects, engineers and scientists in the future, when it comes to precisely dimensioning
ADS for various buildings and daylight conditions.
