building

500 Jefferson Street is a 20-story, 390,000-square-foot office tower owned and operated by Brookfield Properties. The building is part of the Cullen Center, a four-building, mixed-use complex totaling 3.1 million square feet. The Cullen Center buildings are connected by sky bridges and offer amenities including a food court, the Crowne Plaza Cullen Center Hotel, and two full service banking facilities, along with numerous other retail amenities and conference facilities.

Built in 1962 and designed by Welton Becket architects, 500 Jefferson Street is a steel-frame building with pre-cast concrete curtain wall panels. The building offers quarter-inch vision glass, which provides noise abatement and efficient insulating qualities, as well as solar load control. The curtain wall system has setbacks that break up the visual line of the individual floors. The spacious entry lobby and concourse level have 20-foot ceilings, energy-efficient down-lights, travertine marble wall treatments, and terrazzo flooring. Floors 3 through 20 each have 9-foot ceilings, energy-efficient fluorescent light fixtures, and motion sensors to turn off any unneeded light fixtures.

The building proudly earned the ENERGY STAR for superior energy performance as the result of an extensive energy reduction program implemented throughout Brookfield Properties' Houston portfolio starting in 1998. Lighting fixtures throughout the building have been retro-fitted with energy-efficient electronic ballasts and T8 fluorescent lamps. The HVAC system is clean and well-maintained to promote energy efficiency as well as excellent indoor air quality (IAQ) for all tenants and guests in the building. Air filtration has also been upgraded over recent years to improve IAQ. Periodic third-party IAQ testing is performed regularly, and any idiosyncrasies are documented. Engineers receive regular and ongoing IAQ training to stay abreast of leading technologies. The centrifugal chillers have been replaced by more energy-efficient machines that use a more environmentally friendly refrigerant.

Energy consumption throughout all Brookfield buildings in Houston is managed through an energy management system (EMS). This system automates lighting and controls all HVAC equipment including chillers, air handlers, pumps, cooling tower fans, and exhaust fans. A software program automatically reads and compares interior and exterior temperatures and calculates the appropriate times for air handlers to meet pre-selected acceptable temperatures at 7:00 a.m. each weekday. Every minute saved by the system calculates into energy savings for the tenants. Each piece of HVAC equipment connected to the EMS can be controlled from any location in the world, allowing quick response times to emergencies and changing conditions. All equipment is supervised 24/7, maximizing the operations and energy efficiency of the building.

Brookfield Properties is proud to participate in the ENERGY STAR program. As a leader in the commercial real estate industry, Brookfield Properties is committed to owning, developing, and managing premier office properties that are sustainable, environmentally friendly, and technologically advanced. The company continues to expand and enhance the features, systems, and programs that foster energy efficiency in its buildings, as well as the health and safety of all tenants, employees, and the community.
