It is vital to ensure that while the requirements of on-pitch lighting are achieved, the off-pitch lighting levels are properly controlled, and calculated at the planning stage to ensure compliance with best practice standards.
A typcial 1st floor bedroom is approximately 5 metres above ground level, so the vertical illuminance at height 5 metres is of critical importance. The measurements ("Ev") is depicted on the vertical surface included in each of the following template schemes.
In all these schemes, the lighting levels quoted are "maintained" levels since they already take account of lamp output decline over life. All figures shown in these schemes are achieved without tilting the floodlight. |
