The recent 2010 Energy Performance of Buildings Directive (EPBD) and the existing UK benchmarks place a high demand on building professionals towards the design of nearly zero energy buildings. The energy consumption for lighting in retail buildings accounts for 40% of the overall energy consumption. Thus, the energy use of the lighting system is one area where significant energy savings are possible. This paper investigates the effectiveness of using LEDs for general lighting in a typical retail application
and is a project conducted under the auspices of the BRE (British Research Establishment).
The proposed LED lighting systemis designed and simulated in Dialux so as to satisfy the required illuminance levels according to the regulations and at the same time to offer a more energy efficient and cost effective lighting solution. To take this a step further, the integration of a photovoltaic panels system to supply the lighting system is assessed and RETScreen software is used.
