Most designers would agree that natural light is essential to the experience of any great work of architecture, but as a professional discipline, we lack consensus on which characteristics of daylight quantify or qualify the visual performance of a space. Perceptual qualities such as brightness, contrast, and temporal variability influence our experience of physical space and while illumination...

Original scientific paper The model proposed in this paper is based on a multi-criteria analysis of annual daylight illumination relying on the interoperability of commercially available software tools. The daylight performance of different urban morphologies is investigated by simulating and measuring real weather conditions for a specified location on two types of 3D models. The first analysi...

The paper addresses the design of large roof structures for semi outdoor spaces through an investigation of a type of performance-oriented design, which aims at integrating performance evaluations in the early stages of the design process. Particularly, aiming at improving daylight and thermal comfort under large structures, the paper focuses on the exploration of passive solar strategies to re...

In commercial buildings, smart lighting control systems are applied to minimize the electrical energy consumption. These systems use occupancy and light sensor data to adapt artificial light in accordance with changing occupancy and daylight conditions. In these systems, the performance relies on a pre-calibration phase to achieve daylight adaptation of artificial light. Since the pre-calibrate...

Smart window designs have emerged as a means of providing dynamic regulation solar energy and daylight, enhancing indoor comfort, achieving building conservation. We evaluated novel design that integrated thermotropic (TT) material Transparent Insulation Material (TIM) present the investigation in this paper. The Parallel Slat TIM (PS-TIM) structure contained within unit provides extra thermal ...

background: this paper investigated the effect of daylight on morning and night melatonin, subjective general health using ghq questionnaire, sleepiness and alertness on elderly who lived in nursing houses. methods: nineteen nursing home residents participated voluntarily. they exposed to daylight from 9 to 10 a.m. and from 4 to 5 p.m. for 6 wk. the level of melatonin in the morning and at nigh...

This paper reports on the daylighting performance of switchable ethylene-tetrafluoroethylene (ETFE) foil in double-skin façades (DSF). In contrast to conventional glazing or static ETFE façades, moderates incident daylight and controls internal light distribution by actively responding weather conditions solar intensity. To better understand control function impact parameters such as climate, l...
