Owned and managed by Hines, One Greenspoint Plaza is located in North Houston's prestigious 13.5-acre mixed-use Greenspoint Plaza development. The building is one of six Class A buildings, which together total more than 2 million square feet. Greenspoint Plaza has had over 95 percent occupancy for the last 5 years. The buildings are connected by a covered walkway, which forms the storefront overhangs for three one-story retail centers between the office buildings.

One Greenspoint Plaza, built in 1978 and expanded in 1999, is a 223,159-square-foot, eight-story tower designed by S. I. Morris and constructed of steel-reinforced poured-in-place concrete. The exterior walls are a combination of painted aluminum panels with a bronze glass curtain wall, providing superior energy and shading co-efficient factors. The dual-pane vision glass provides noise abatement and highly efficient insulating qualities. The curtain wall system has various architectural reveals and setbacks that break up the visual line of the individual floors (each approximately 13 feet tall). Brick masonry walls at the ground-floor walkway accent the building and provide continuity with the adjacent 36,891-square-foot Gallery I retail center. The building has a covered walkway off the southeast side to Garage 1 and 2; an additional covered walkway connects One Greenspoint Plaza to the adjacent Wyndham Hotel.

One Greenspoint Plaza earned the ENERGY STAR for superior energy performance as a result of an extensive renovation undertaken in 1999-2000, and additional retrofits more recently. Lighting fixtures throughout have been replaced with high-efficiency T-8 fluorescents, creating constant energy savings versus the previous fixtures. On the HVAC side (which is an enormous driver of energy consumption in Houston's scorching summers), all air handling units in One Greenspoint Plaza are fitted with variable frequency drives (VFDs), which enable their operation to correspond closely to actual demand. In addition, the central plant for the Greenspoint Plaza complex, which serves One Greenspoint Plaza, was retrofitted with a new chiller that can cycle between 500 and 1,500 tons of chilled water, depending on demand. Overall, energy consumption at One Greenspoint Plaza is monitored and managed with a digital energy management system, helping building managers track and react to changes in energy consumption.

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
