Development of annual daylight simulation algorithms for prediction of indoor daylight illuminance

Energy and Buildings, 2016
Abstract An annual daylight simulation method (ADSM) has been developed in this study to predict daylight illuminance under diverse sky conditions. The ADSM simulation results were validated by comparing them with Radiance software simulation results and field measurements. Classroom and small private office space facing south and north were used for

Computer Simulation in Daylight Design: A Comparison

Architectural Science Review, 2001
Four of the leading computer lighting simulation programs are compared with physical modelling techniques as a means of predicting daylighting of interior spaces. Lightscape (v3-l.l), RadioRay (v2.0), Microstation/J (v7.1Beta) and ADELINE (v2.0NT) are compared with a physical model under two types of artificial sky.

Daylight simulator

Applied Optics, 1987
We looked into what was required to make an artificial source similar to CIE daylight D(65) spectral power distribution. As a result, an artificial light source was developed with its 300-700-nm relative spectral power distribution similar to that defined by CIE D(65), based on a quartz-halogen lamp and colored absorbing glass filters in a side-by-side

Fabrication of a tunable daylight simulator

Applied Optics, 2010
Recently, solid state lighting has begun to play an important role in colorimetric instrumentation. LEDs are being evaluated as one of the possible standard light sources for such devices. In this study, an innovative tunable daylight simulator is developed, which mainly consists of only a few LEDs and a specially designed optical thin-film filter with

Standard daylight coefficient model for dynamic daylighting simulations

Building Research & Information, 2008
Daylight coefficients are normalized contributions from discretized sky or ground segments, or preset solar positions, to solar quantities calculated at various building sensor points. Once generated, daylight coefficients can be folded against luminance efficacy and distribution models to calculate, for instance, time series of illuminances.

A radiosity approach for the simulation of daylight

1995
In this paper, an extension to the radiosity method, for the simulation of daylight, is presented. The sky hemisphere around the scene is subdivided into a set of sky patches. By defining a location on the earth, a time of day and the weather conditions (e.g., clear sky, overcast, partly cloudy) a sky model (e.g., CIE or Perez) is applied to compute ...

Glass Filters for Simulating Daylight in Sensitometric Exposure

Applied Optics, 1968
Two glass filters for the sensitometric exposure of daylight films are described. The filters are each made of four glass color filters. The thickness of the four glasses is chosen to match two types of relative energy distributions of sensitometric daylight with a tungsten lamp operated at 2850 degrees K.

Daylight simulators and colour vision tests

Ophthalmic and Physiological Optics, 1998
Summary Our previous studies have shown that the influence of the illuminating source used for colour vision examination on the intended function of the test is very test dependant, some being relatively unaffected by source characteristics while others can be significantly affected.
