Seattle City Light provides incentives for builders, developers, and architects who construct energy efficient multi-family buildings. The program is designed to encourage the construction of buildings which provide maximum comfort and also incorporate resource conservation. Incentive amounts are broken into three categories, which vary depending on wall depth and glazing area as a percentage of the conditioned floor area. Incentives are available for: 

  • Extra insulation in floors, walls and ceilings
  • Energy-saving windows
  • Long-lasting, energy-efficient lighting
  • Healthy ventilation and high-efficiency thermostats
  • Energy and water-efficient clothes washers

Some measures are completely optional, while others are mandatory for project eligibility. A complete list of program options, resources, incentive schedules, and program requirements are available on the program web site listed above. A BUILT SMART inspection is required for eligibility. Contact Seattle City Light for further information on this program.
