5. Minimise glare
Modern lighting, and in particular LED products, should have optics, accessories and glazing that control light far better than ever before, When we say minimise, really, we mean don’t generate any at all. Using the right amount of light at the right time and in the right place is better for the environment and your energy bill.
Lighting should be concentrated onto the main car parking area with careful consideration given to adjacent buildings. If the car park is in a residential area, consider light spill into back gardens or windows – as this could constitute a statutory nuisance if the resident complains to their local authority.
Keep column numbers to a minimum. Bracket arms and luminaires with zero degree inclinations and choose light sources with minimal upward light. The use of fewer columns, but higher mounting heights, may help minimise clutter and maintenance points.
For larger car parks using a higher-powered light source with taller mounting height, can often be the most economical way to light a large area and far less obtrusive than a “forest of columns” but all the points above still remain a consideration.
