Seattle City Light offers home energy audits for $95 to City Light customers living in single family homes. Several of the Mighty House Construction community have been taking advantage of the City of Seattle discount. Auditors certified by the Building Performance Institute will visit your home and conduct a thorough assessment of its insulation level, leakiness, and heating system efficiency, as well as installing free energy conserving compact fluorescent light bulbs. You will receive an “Energy Performance Scorecard” that rates the current efficiency level of your home, a bit like the MPG rating for a car. The other benefit of the report is that it comes with suggested energy improvements, their estimated costs, and their potential for energy and climate impact reduction — giving you the information you need to make tough decisions in spending your cold hard cash.
