Owned and managed by Hines, Four 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 more than 95 percent occupancy for the last 5 years. The buildings are connected by a covered walkway, which forms the storefront overhangs for the three one-story retail centers between the office buildings.

Four Greenspoint Plaza, built in 1983, is a 410,567-square-foot, 23-story tower designed by Sikes Jennings Kelly and constructed of steel-reinforced poured-in-place concrete. The exterior walls combine anodized metal with a bronze glass curtain wall, providing superior energy and shading co-efficient factors. The vision glass is dual-pane for noise abatement and highly efficient insulating qualities. The building contains 12 patio roof sections at staggered elevations and a main penthouse roof with gold-tone reflective coated glass. Each individual floor is approximately 12 to 13 feet tall. The north ground-floor entrance contains glass-in-bronze anodized aluminum frames with two pairs of double-glass doors separated by a vestibule entrance. The south ground-floor entrance is open to the grand lobby of the Wyndham Hotel.

Four Greenspoint Plaza earned the ENERGY STAR for superior energy performance as a result of extensive retrofitting to elements of the property's energy-consuming infrastructure. Lighting fixtures in approximately 25 percent of the property have been replaced with high-efficiency T-8 fluorescents, creating constant energy savings versus the previous fixtures. On the HVAC side, air-handling units have variable frequency drives (VFDs) that allow their operation to correspond closely to actual demand; chillers for the property have VFDs as well. In addition, Four Greenspoint Plaza's three-cell cooling tower has been replaced with a two-cell stainless tower with VFDs. Overall, energy consumption at Four Greenspoint Plaza is monitored and managed with a digital energy management system, helping building managers to track and react to any 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 www.hines.com/sustainability.
