Oak Brook Regency Towers is a Class A office property located in Oak Brook, IL, a dynamic suburb of metropolitan Chicago.  The property is managed by Cushman & Wakefield of Illinois, Inc. and consists of two thirteen-story office buildings connected by a one-story retail concourse with a total net rentable area of 402,318 square feet.  Amenities include a fitness center, a full service bank and a first-class, well-known Italian restaurant. 

Originally developed in 1977, an extensive property redevelopment program was undertaken in 1991 and completed in 1993.  The renovation included the addition of the retail concourse and lobby rotundas along with common area upgrades, mechanical system refurbishments and parking garage reconstruction.

As part of ongoing energy management efforts, several upgrades were completed in 2008.  All stairwell, washroom, mechanical room and fan room light fixtures were retrofitted to T8 fixtures and mercury vapor can lights in the retail concourse were retrofitted to accommodate CFL bulbs.  Timers were installed on the water heaters and recycling pumps to reduce hours of operation and the chillers are now utilizing the automatic chilled water reset which adjusts the chilled water temperatures to maintain desired discharge air temperature automatically.

In addition, ongoing projects include replacement of existing exit lighting with LED fixtures in all new construction, installation of motion sensors in the washrooms, replacement of 32 watt bulbs with 25 watt bulbs in building standard light fixtures and installation of energy efficient lighting and water efficient plumbing fixtures in washrooms as they are upgraded.

TIAA-CREF, owner of Oak Brook Regency Towers, is the first financial services firm to win the ENERGY STAR Partner of the Year Award and is partnering with ENERGY STAR to improve energy performance and measure progress toward its goal.  So far, TIAA-CREF office buildings have reduced energy use by 125 million kBtu - equivalent to powering more than 2,500 homes for a full year.


In 2008, on behalf of TIAA-CREF, over 1,000 CFL bulbs were distributed to the tenants at Oak Brook Regency Towers along with energy saving information.
