Abstract

Daylighting has been recognized as an essential element in architecture for enhancing visual comfort, energy-efficiency and green building developments. An appropriate lighting control linked with daylight can save electric lighting energy consumption and reduce peak electrical demands. In well day-lit spaces such as atria, daylight-linked lighting controls can provide substantial energy reductions. This study presents the visual performance and electric lighting energy use for an atrium building using high frequency dimming controls. The general features and characteristics of the results including electric energy expenditures and daylight illuminance were reported. Simple prediction approaches were used to demonstrate the lighting savings. The findings revealed that the dimming controls could be applicable to places with similar architectural layouts and lighting schemes. © 2013 Published by Elsevier B.V. All rights reserved.
