green-building-engineeringAble is a “green building” engineering firm that supports and promotes environmental stewardship. We work to preserve customers’ assets in a sustainable fashion that improves tenant satisfaction and productivity, upgrades indoor environmental quality, conserves energy, and balances budgetary objectives through cost savings.

leed-logoAble’s engineering teams have played major roles assisting the Joe Serna Jr. CAL EPA building with becoming the first Platinum Certified LEED EB building in the United States with an Energy Star rating exceeding 95. Able currently maintains more than 50 buildings that are LEED certified. Of those buildings, 21 are Platinum, Gold and Silver LEED status, including the first Platinum LEED EB building in the US.

LEED, or Leadership in Energy & Environmental Design, is a green building certification program that recognizes best-in-class building strategies and practices. To receive LEED certification, building projects satisfy prerequisites and earn points to achieve different levels of certification. Prerequisites and credits differ for each rating system, and teams choose the best fit for their project. Leadership in Energy and Environmental Design (LEED) recognizes, supports and promotes green buildings through a comprehensive system offering project certification, professional accreditation, training and practical resources.
