Daylight Impact on Energy Performance of Internal Lighting

IEEE Transactions on Industry Applications, 2011
Daylight in interior offers a considerable contribution of energy saving, the key is to design an integrated lighting system between the electric lighting system configuration and its control strategy. An optimal lighting system has to consider the different presence of daylight in the zones to arrange the most favorable luminaires layout. An automatic

Daylighting Performance in Residential Buildings

Architectural Science Review, 1999
The amount of daylight entering a building and its distribution depend an both interior and exterior factors. In Hong Kong, most buildings are built close to each other and hence the external environment plays a significant role in the daylighting designs.

Daylighting performance of optical rods

Solar Energy, 2003
A novel tubular daylighting device, the light rod, is shown to have high transmittance throughout the day in Singapore. Constructed of an optical quality polymer and clad by air, the light rod is intended for use in buildings where fabric constraints prevent the use of larger daylighting devices.

Daylight Performance of Buildings

2014
As part of Daylight Europe, the daylighting behaviour of 60 buildings was observed and measured during a three year period. Buildings of many different types, sizes and ages were included - from offices to museums, libraries, churches, houses, airports and factories; from Classical buildings to modern constructions, and from a small single room to an ...

Daylight performance predictions

2019
Daylighting describes the use of natural light in buildings. The objectives for daylighting a building are manifold and range from questions of aesthetics, occupant health and comfort to energy savings for lighting and space conditioning. Daylight simulations can help design teams to address these multiple aspects by allowing them to (a) predict the

Total Energy Performance of Atria with Daylight

HKIE Transactions, 2006
The current design trend for commercial buildings in Hong Kong is to introduce shopping arcade at the lower floors and provide atrium with daylight. If daylight is properly utilised, the electrical lighting energy can be saved. On the other hand, introduction of atrium will allow the entrance of solar heat which will introduce extra cooling load to the

Daylighting performance of sawtooth roofs of industrial buildings

Lighting Research & Technology, 2003
Natural lighting in industrial, commercial and sports buildings is usually provided by roofs with transparent surfaces. Sawtooth roofs, in which opaque modular elements are combined with transparent surfaces, whether inclined or in various shapes, are especially popular.

Daylighting Impacts on Retail Sales Performance

Journal of the Illuminating Engineering Society, 2002
This paper reports on a study of the effect of daylighting on sales performance. In this project, we established a statistically compelling connection between sky-lighting and retail sales. The methodology used to conductthis research is described and the results are presented and interpreted.

Daylighting Impacts on Human Performance in School

Journal of the Illuminating Engineering Society, 2002
The purpose of this study was to see if we could demonstrate a clear relationship between the presence of daylight and human performance in buildings. In this study we used a statistical technique called multivariate regression analysis, which analyzes the importance and impact of many variables simultaneously.
