External

Pathways & Pedestrian Areas, Facade & Building Perimeter, Complex & Estates

A number of factors need to be considered when designing external lighting schemes: Safety In areas where both pedestrians and vehicles are present, it is essential that the lighting help keep both groups safe. Security Lighting is a very effective deterrent but leaving security lighting on all night consumes significant amounts of energy. Energy Saving If external lighting is left on overnight, then it may be on for more than 4,000 hours per annum, resulting in increased energy consumption and costs. Obtrusive Light Stray light onto adjacent properties (especially domestic) should be avoided to prevent nuisance.
