The Hewitt Associates building in Orlando, FL, is a six-story commercial office building that is occupied entirely by Hewitt Associates. The building was constructed in 1999 and is managed by Jones Lang LaSalle. The building was built with energy efficiency in mind. When opened, it won an award from ASHRAE for its "contribution to innovative design that complies with ASHRAE standards for indoor air quality and energy efficiency." Since opening, proper maintenance, upgrades, and reduced run times have helped keep energy costs at a minimum. Building management has continued to lower energy usage, even as the building population has increased from the original design number of 1,250 to the current number of 1,825 associates.

A few of the energy efficiency measures incorporated into the Hewitt building were: a building automated control system (BAS) with direct digital controls (DDC) controls for the HVAC and lighting; motion detectors for the majority of work space lighting; a heat wheel system that pre-heats/cools fresh air using the exhaust air; and variable frequency drives (VFDs) on all air handler units.

 

Energy performance upgrades since 2004 include:

• Shortening run times on HVAC units.
• Replacing incandescent bulbs with compact fluorescent bulbs.
• Reducing irrigation run times.
• Reducing temperature and run times on gas-fired water heaters.
• Reducing times lighting is used.
• Maintaining and repairing equipment to keep it running at peak performance.

 

In addition to these upgrades, adding VFDs to chillers, BAS upgrades, and more aggressive reduced run times in 2007 showed a savings of $50,000 over the same period of time from 2006. The addition of VFDs to cooling towers along with a new tower water temperature reset and more BAS upgrades in 2008 have made it possible to increase the building's energy performance rating to the top 25 percent in the nation, earning the Hewitt Associates building the ENERGY STAR for superior energy performance.

Communications:

Postings outlining energy initiatives and the ENERGY STAR Award will be placed on The Source, Hewitt's internal Web site, One Source, Jones Lang LaSalle's internal Web site, and the local chapter of BOMA. The plaque will be displayed in the client entrance to the building.

Testimonial:

"The property staff is not resting on the fact we have an efficient building; we are always looking for new ways to reduce energy and costs.  More BAS upgrades, adjustments to HVAC run times and set points, vending machine occupied sensors, parking lot lights upgrades, Associate education, and other energy saving devices are always being considered and budgeted for."
