Lighting consumes about 19% of the electricity used around the world, and since inefficient
lighting sources are still in use worldwide, there is great potential for electricity savings. Even …

Anecdotal evidence suggests that the correlated color temperature (CCT) of light can affect
thermal comfort. Previous literature mostly investigated this effect over a short duration (< 1 …

Roadway lighting was one of the earliest applications for electric lighting technologies. Well-
designed roadway lighting offers many benefits and aids the visual tasks of drivers and …

The public buildings sector represents one of the most intensive items of EU energy
consumption; the application of retrofit solutions in existing buildings is a crucial way to …

A series of CaZr4 (PO4) 6: Dy3+, CaZr4 (PO4) 6: Ce3+ and CaZr4 (PO4) 6: Dy3+, Ce3+
phosphors were prepared by the solid state reaction process. The phase formation was …

Recent studies have suggested that thermal and visual comfort are correlated, although the
causality underlying this correlation is unclear. Personal control of correlated color …

With advanced heating, ventilation, and air conditioning (HVAC) and colour tunable LED
lighting systems, indoor environmental parameters can be precisely controlled. In most …

This paper examines how the lighting colour temperature affects indoor thermal comfort. A
test room with three separate environments was set and, in each one of them, a lamp with a …

The recent ban on conventional incandescent lamps for residential use led Brazilian
consumers to choose from three main lighting technologies: incandescent halogen, CFL …

Two mock-up office rooms, one with a spectrally tuneable LED lighting system and the other
with a fluorescent lamp (FL) lighting system were built for user acceptance studies for office …
