Developed and managed by Hines, Calpine Center is a 33-story, 705,000-square-foot office tower in downtown Houston, TX. Designed by Hellmuth, Obata & Kassabaum and completed in 2003, Calpine Center is clad in a combination of architectural precast concrete, pink granite, and mirrored glass and includes an attached, 900-space enclosed parking structure. Visitors to the building are welcomed in a two-story lobby finished in wood veneers, granite, and natural stone with accents of polished metal and glass.
Calpine Center was specifically designed to be a highly energy-efficient building. Calpine Center earned the ENERGY STAR for superior energy performance largely as the result of features original to the building. In the often-steamy Houston climate, air conditioning is a significant driver of energy consumption; Calpine Center is equipped with variable frequency drives (VFDs) on all internal and external air handling units and cooling tower fans, allowing their operation to closely follow actual demand. In addition, levels of carbon dioxide in return air are constantly monitored, and the quantity of outside air that is supplied to each floor is modulated accordingly. The energy savings that result from these features is complemented by automated lighting controls on all of Calpine Center's lighting.
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.
