PORTLAND–A recent study by Portland-based Earth Advantage Institute reveals that Energy Star and LEED certification for new and existing homes not only saves money but might also raise resale value. The study, conducted over four years in the six-county Portland metropolitan area, found that newly constructed homes with third-party certifications for sustainability and energy efficiency sold for 8% more on average than non-certified homes, and existing homes with certifications sold for 30% more. A similar study was also conducted Seattle, showing 9.6% price premium with certification. While the results are inconclusive, they are compelling.
