5th Edition) and lighting layout for an office.
Each of the lighting fixtures (luminaires) shown in the lighting
has a single 150-watt lamp. Each of the luminaires is cleaned
once per year by the facilities maintenance staff. It takes
an average of 5 minutes per fixture (for a single maintenance
staffer) and maintenance time (labor wages plus benefits) is
estimated to cost $40 per hour. The cost for cleaning
supplies and consumables (cleaning clothes, etc.) is minimal and
makes up a small percentage of the overhead factor included in the
$40/hour rate. Luminaire re-lamping is scheduled every six
years (at 75% of rated lamp life) at a cost of $15.00 per lamp for
the lamp itself and a time budget of 10 minutes per luminaire at
the standard $40 per hour rate.
