Owned by National Office Partners, a venture of CalPERS and Hines, and managed by Hines, Wellesley Gateway is a four-story, 270,000-square-foot office building on a 5.7-acre site in Wellesley, Massachusetts. Completed in 2000, the building was designed by Elkus/Manfredi Architects; a two-story atrium welcomes visitors, while a red-brick exterior with translucent glass and aluminum accents both references and updates the New England architectural vernacular. Wellesley Gateway is fully leased to Harvard Pilgrim Health Care and offers an on-site cafeteria, an employee fitness center, and surface and structured parking for some 1,100 vehicles.


Wellesley Gateway earned the ENERGY STAR for superior energy performance as a result of improvements to building management practices and select retrofits to building infrastructure. HVAC management was an initial focus, with building engineers making changes such as a reduction in static pressure in HVAC supply ducts--allowing the speed of supply and return fans to be reduced by some 8 percent and the use of a more efficient natural gas system for morning warm-up instead of electricity.  Lighting retrofits were identified, with incandescent lighting in common spaces, such as the cafeteria, replaced with high-efficiency compact fluorescent lamps. HVAC was another upgrade target, with variable frequency drives (VFDs) installed on condenser fan motors to help these motors run at speeds closer to levels reflecting actual demand.


Hines has been recognized with multiple ENERGY STAR Sustained Excellence and Partner of the Year awards. For a summary of the firm's participation in the ENERGY STAR program and other sustainability information, visit
