Daylight performance of toplighting: An overview

2021
Novel and advanced daylighting strategies and systems can noticeably decrease artificial lighting consumption and considerably improve light quality in the interior environments. In modern architecture, employment of rooflights is prevalent since they transmit daylight into deep plans or spaces lacking facade.

The performance of innovative daylighting systems

Renewable Energy, 1994
Abstract Innovative daylighting systems have four key aims; to increase daylight levels deep within rooms, to improve daylight uniformity, to control direct sunlight and to reduce glare. Results from experimental studies at the Building Research Establishment (BRE) indicated that the systems tested (prismatic glazing, prismatic film, mirrored louvres

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.

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

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 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 of Manual Solar Shades

Light & Engineering, 2018
The daylighting performance improvement of manual solar shades was compared with two conventional window scenarios. A developed stochastic model for manual solar shades was used for co-simulation by BCVTB. Results show that manual solar shades increase useful daylight illuminance by approximately 160 % compared to conventional windows with less ...

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 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.
