This paper analyzed the accuracy of simplified glare analysis methods compared to the Daylight Glare Probability (DGP) through a parametric study. It consisted of glare calculations in a sample office room, with varying façade layout and orientation. Calculations were performed with Radiance, obtaining the simplified and full glare indices for each case. The different options were compared for ...

This paper reports the simulation approach and prediction of annual energy performance of PV ventilated glazing systems with daylight saving as applying to typical office environment. Our computer model was developed via the ESP-r simulation platform in association with the RADIANCE lighting software. The new attempt of using indirect interaction between the two simulation programs through dayl...

A large number of possible PV-powered products should be able to operate under indoor lighting conditions. In order to make good product designs of indoor operated PV-devices (ipv), a more extended dataset of PV characteristics than just standard test condition (STC) parameters is required. Within the SYN-Energy project framework, which aims to improve design methods for PV-powered consumer dev...

Typical daylight extends from blue (morning sky) to orangey red (evening sky) and is represented mathematically as the Daylight Locus in color space. In this study, we investigate the impact of this daylight variation on human color vision. Thirty-eight color normal human observers performed an asymmetric color match in the near peripheral visual field. Unique hues were identified using a namin...

This paper presents an optimum design of a photovoltaic (PV) power system for the satellite market using high efficiency solar cells. This is to enhance the power capabilities of the satellite solar arrays without extra challenges in area, weight and budget constraints. In this way, the designed power system can efficiently fulfill the power requirements of the satellite subsystems, either in d...

Architectural lighting is now simple and emotionless due to modern technological innovations, which makes it difficult recognise the distinct character of a place. With development air conditioning artificial systems, architects are more inclined adopt them than design equivalent spaces in natural light, thus, taking advantage ideal conditions raise quality space. The major difference between l...

Daylighting is desirable in classrooms but can pose a challenge to classroom illumination when there risk of discomfort from glare windows and sunlight. There are several metrics use for the evaluation daylight, none has yet been validated based on field-of-view conditions classrooms. A previous study found that Daylight Glare Probability (DGP) produced relatively better predictive power report...
