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...

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. ...

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...

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...

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...

The renewable energy has been attracting attention as a new alternative energy due to the problem of environmental pollution and resource depletion. In particular, daylighting and PV system are regarded as the solutions. In this paper, the hybrid dimming control system supplied by solar cell and daylighting system was designed. Daylighting system is main source and PV system is spare source. PV...

The objective of this paper is to estimate the potential for electricity savings with the use of daylighting integrated with the artificial lighting system and hybrid ventilation in commercial buildings located in Florianópolis, southern Brazil. Several models were analysed. Two cases were investigated: a reference case, operating only with air-conditioning system and another one with the use o...

In this paper, we propose an expert system for daylighting in architecture which is used to guide a goal-oriented, user-interactive design process. This system is supported by a knowledge-base which has been populated using a set of previously completed simulations using the Design of Experiments methodology. The knowledge-base contains information regarding the effects of a variety of design c...

The main objective of this work is to develop a method for sizing window area based on the consumption of electricity in commercial buildings, when integration of daylight and artificial light with hybrid ventilation is considered. The method allows the estimation of the potential for electricity savings and the evaluation of the daylighting performance. Models operating with artificial and nat...
