The move is designed to encourage higher levels of energy efficiency in Arlington buildings that go above and beyond the LEED minimum requirements. It also addresses the building energy efficiency and greenhouse reduction goals listed in the Community Energy Plan, which was launched in 2010. The Green Building Bonus Density Initiative was last updated in 2009.
Under the new guidelines, commercial office projects interested in participating in the incentive program must be at least 20 percent more energy efficient than the baseline, and achieve LEED Silver certification or higher. Multi-family residential buildings interesting in participating must be 18 percent more energy efficient than the baseline, and achieve at least LEED Silver certification. Previously, the county did not have its own standards, but required buildings to comply with the LEED standard of being 10 percent more energy efficient than the baseline.
