Built Smart Users Manual | Specifications | Alerts | Water



This is a Seattle City Light BUILT SMART project and the following requirements must be met when constructing a BUILT SMART building in the Seattle City Light service area.

Energy efficient lighting (including exit signs) is required in all exterior residential common areas of any BUILT SMART project receiving incentives for thermal envelope upgrades. REMINDER: All interior residential common area lighting must meet the 2001 Washington State Energy Code of 1 watt per square foot.

Exterior Common Area Fixture Review and Inspections
All fixtures shall be reviewed and approved prior to installation and inspected after installation.

Exterior Common Area Fixture Locations
Exterior common area lighting fixtures shall be located outside the thermal envelope of the building and connected to the common house meter. Exception: townhouse type entry fixtures may be connected to tenant meter. (Refer to local energy code for parking garage lighting requirements.)

Exterior Common Area Fixture Specifications
  • All lamps must have a Color Rendition Index of 70 or better (except HPS).
  • Only T-5 or T-8 lamps are allowed where linear fluorescent fixtures are installed.
  • T-5 or T-8 fixtures must have electronic ballasts.
  • Compact fluorescent fixtures require high power factor ballasts.
  • All fixtures must be hardwired.
  • No T-12 circline type lamp/fixtures are allowed.
  • Where fluorescent lamps are used, low mercury content is strongly urged.
  • All exterior fixtures must be suitable for damp or wet location, where required.
  • All exterior fixtures must be controlled by a photo cell.
Interior Common Area Lighting Locations
All interior residential common area lighting installed in the common areas shall be connected to the residential common house meter.

Interior Common Area Lighting Efficiency
All interior residential common area lighting must have a lighting power. (See Appendix A for Lighting Calculation Worksheets). The financial incentive amount is based on the actual installed lighting power density and will be identified in your BUILT SMART agreement.

Note: Seattle City Light recommends that all common areas in Multifamily buildings have a minimum of 5 foot-candles over the entire common area spaces being considered. Reference Category B of the Lighting Handbook 8th Edition, Reference and Application, IESNA for details. Interior Common Area Lighting Review
A set of architectural drawings (including common area square footages), a reflective ceiling plan, a fixture schedule and the manufacturers specifications sheets for the residential common areas must be submitted for review prior to installation.

Interior Common Area Lighting Specifications
  • All lamps must have a Color Rendition Index of 70 or better.
  • Only T-5 or T-8 lamps are allowed where linear fluorescent fixtures are installed.
  • T-5 or T-8 fixtures must have electronic ballasts.
  • Compact fluorescent fixtures require high power factor ballasts, and if switched or controlled, require flicker free/quick start lamps.
  • All fixtures must be hardwired.
  • No T-12 circline type lamp/fixtures are allowed.
  • All exit signs that exceeds 5 watts shall be included in the lighting power density calculation.
Exceptions
This program allows deviations from the lighting requirements for specific unique architectural details. Any exception must be reviewed and approved on a case-by-case basis by a BUILT SMART program representative.
