Consideration to the natural elements, such as daylighting, at the earliest in the architectural design process is suggested by many as necessary for sustainable buildings. The implementation of a successful daylighting strategy in the design of buildings improves spatial quality and saves energy required, otherwise, for artificial lighting. Daylighting becomes a design mandate in the case of c...

Proper use of daylighting cannot only improve the visual comfort in indoor environment, but also reduce building energy consumption effectively. Studies on this topic have been mostly conducted for office buildings, but were limited for industrial buildings, where lighting is a major electricity consumer. This paper presents a study of daylighting performance in a large space industrial buildin...

We present a study of a tangible user interface for design and simulation applied to architectural daylighting analysis. This tool provides an intuitive way for architects and future occupants of a building to quickly construct physical models and interactively view in them a projected simulation of resulting daylighting. A user study was conducted of both architecture students and non-architec...

This paper traces the historical development of different daylighting calculation methods. Over the years there have been several developments in daylighting calculation methods. The last two decades have seen a number of new ideas and approaches in daylight calculation procedures. Recently, selected methods have been incorporated into the building energy performance simulation tools. This pape...

Orientation of classrooms is an important challenge in architectural design of a school. However, there is a lack of appropriate knowledge about influence of orientation on students’ perception of daylighting in classrooms. This paper presents a questionnaire survey that was conducted to compare students’ perception and satisfaction with daylighting in classrooms of a high school in...

Repeated modifications of multiple design parameters are required to optimize daylighting system design. However, a large number of optional design parameters increase the computation time. This research developed a simulation-based model to evaluate daylighting system design based on system daylighting and thermal performance. The model utilized the prediction methods to speed up computation. ...

A questionnaire survey was conducted to investigate the effects of daylighting and human behavior patterns on subjective luminous comfort in Hong Kong housing units. The participants were recruited via mail, and included residents of both public and private housing units. 340 questionnaires were returned and analyzed by using SPSS 19.0. In analyzing the response statistics, the Cronbach's alpha...
