building

515 Post Oak is a 12-story, Class-A office building located in Houston, Texas. The building, constructed in 1980, is owned and managed by Columbia Property Trust, a national purchaser and manager of Class-A office buildings across the United States.

 

Columbia has installed new high-efficiency cooling towers, chilled water pumps, and chillers, all with variable-speed drives, to provide a significant reduction in electricity used to air condition the building. Efficient lighting fixtures were incorporated into a recent lobby renovation.

 

Water-saving measures featured at 515 Post Oak include upgrading faucet aerators in restroom sinks to 0.5 gpm, replacing all restroom fixtures with Water Sense reduced consumption units, installing automatic flush valves in the restrooms, and upgrading 80 percent of the irrigation system from conventional spray heads to a drip system, all to reduce water usage.

 

515 Post Oak has been awarded the ENERGY STAR for six years in a row (2007-2012). With ongoing energy-saving initiatives and operational improvements, 515 Post Oak has improved its initial energy performance score of 75 in 2007 to a score of 90. With the recent central plant upgrade, Columbia Property Trust expects to realize additional energy savings that will further improve the ENERGY STAR score.
