| Summary: | 碩士 === 國立臺灣科技大學 === 建築系 === 102 === Lighting is the most essential element of building energy consumption. Aesthetically
and sustainably good lighting design requires the combination of maximizing the daylight
availability and minimizing artificial lighting, which in turn greatly reduce the energy
consumption. Lighting simulation can be an effective method to predict the outcome of a
design. A quick and accurate simulation method becomes a necessity for designers and
architects. The objective of this thesis is to develop and validate a novel method for indoor
daylight simulation with commercially available tools. This method incorporates and strings
several techniques and devices that has been scientifically proven or validated, such as the
capturing, processing and analyzing of high dynamic range (HDR) images, the shadow-ring
apparatus, the method of acquiring material properties, and RADIANCE simulation tool.
The aim of this novel method is to provide a quick and accurate tool for both the architectural
designers and researchers.
The results indicate the significance of utilizing correct method of correcting the sky
distribution and how of material properties are acquired, which may improve the simulation
outcome by maximum of 29% and 20%, respectively. Most importantly, the method of
simulating with skydome image and virtual surroundings proves to be effective, improving
the performance of simulations from 5-23%, depending on the surrounding contexts’
complexity. The proposed simulation method is plausible.
