This paper describes the development of a technique for extrapolation of dynamic daylighting simulations from a limited number of high dynamic range photographs. This technique allows us to photographically capture and measure per-pixel lighting quantities from existing spaces in a limited time frame; and the measured information is used to establish a statistics based daylight coefficient mode...

The desert climate is endowed by clear sky conditions, providing an excellent opportunity for optimum utilization of natural light in daylighting building indoor spaces. However, the sunny conditions of the desert skies, in countries like Egypt and Saudi Arabia, result in the admittance of direct solar radiation, which leads to thermal discomfort and the incidence of undesired glare. One type o...

This paper presents the relationship between daylighting performance and shading device design in the perimeter area of buildings. In the area of tropic and sub-tropic, designers always face with the contradiction between solar heat gain and daylighting using. Factors such as different type of shading device, material reflectance, fenestration design, opening ratio, and daylight distribution wi...

This paper proposes an interactive goal-based method for designing daylit buildings. The lighting simulation tool which supports this process is a hybrid global illumination rendering method which efficiently computes annual daylighting metrics. The goal-based method uses a knowledge base populated using a set of previously completed simulations that quantify the effects of various façade desig...

This work introduces RadVR, a virtual reality tool for daylighting analysis that simultaneously combines qualitative assessments through immersive real-time renderings with quantitative physically correct simulations in 6DOF environment. By taking 3D building model material properties as input, RadVR allows users to (1) perform physically-based via Radiance, (2) study sunlight different hours-o...

To evaluate the performance of buildings in use and to predict performance during design, it is necessary to identify what the appropriate measures of performance should be, when and how measures should be collected, and how results will be interpreted to determine success or failure. As noted in Chap. 1, one of the central barriers to effective daylighting is that daylighting performance is of...
