Hi All
We're completing a new build and just finalising our lighting selection.
Because we're post May 2011 we are subject to the 5w/m general, 4w/m patio/deck and 3w/m garage regulations on lighting.
One question I've got (and the question I can't get a straight answer from *anyone* on is); lights like the up/down lights in front of the garage, or the halogen type spot lights that iluminate the backyard - what is the calculation needed (if any) in the BCA requirements?
I read the BCA/HIA FAQ about lighting and it suggests that outdoor lights are excluded because they illuminate an unknown space (perimeter lighting, spots on eves etc). It does illude to another calulcation based on daylight sensors or lumens/watt.
Lighting shops seem to just say not included, but I'm curious does anyone know how these types of lights are treated?
Best Regards
Mark
