CRITICAL DESIGN ISSUES:
Shadows: Locate and orient luminaires to avoid shadowing of mechanical
equipment. Typically, equipment repair requires portable task lighting.
Therefore, lighting should provide clear access to systems but not
necessarily enough light to make repairs.
Target Horizontal Illuminance ( 10%): 300 lux (30 fc)
Adequate light needs to be provided for ease of navigation through mechanical rooms.
Although mechanical rooms may not be used frequently or for long periods of time, if
the lights are left on, a significant amount of energy can be wasted before the next use
of the space. For larger spaces, consider the use of occupancy sensors. In small
spaces, a control with a timer may be appropriate. Add wire guards to luminaires where
they may be struck and damaged.
