Reduced interior common area lighting power densities, controls, and in-unit lighting are optional measures. If installing these measures to qualify for incentives, these requirements must be met.
Interior Common Area Lighting Incentive
The sum of all fixtures located in the residential common areas must calculate to .80 watts per square foot or less. (Any exit sign that is 5 watts or less does not need to be included in the calculation.) "All common areas in MF building shall have a minimum of 5 foot-candles over the entire area of the interior space being considered." - Reference Category B of the Lighting Handbook 8th Edition, Reference & Application, IESNA.
Interior Common Area Fixture Review and Inspections
A set of architectural drawings, a reflective ceiling plan, a fixture schedule and the manufacturers specifications sheets for the residential common areas must be submitted for review and calculation. Your BUILT SMART representative will confirm that your lighting design meets the 2001 Washington State Energy Code and will conduct a lighting power density calculation to determine wattage reductions that meet program requirements.
