The Atlanta Marriott Norcross in Norcross, GA is a six-story hotel with 222 guestrooms, gourmet restaurant and bar, indoor pool and hot tub, and health club. The building, constructed in 1987, is owned and managed by HEI Hotels and Resorts. Recognizing the potential to improve the Atlanta Marriott Norcross' energy and financial performance, HEI turned to the proven strategy of EPA's ENERGY STAR program in 2008 for the tools and resources necessary to help achieve superior energy performance.

By working with ENERGY STAR to make the Atlanta Marriott Norcross more energy efficient, HEI is saving thousands a year in energy costs.

As a first step, the HEI energy management team sought to assess the Atlanta Marriott Norcross' baseline energy performance and to pursue the efficiency gains that could be accomplished through improved operations and maintenance and other low-cost practices. The team was able to leverage utility incentives to conduct a whole-building retro-commissioning survey--a process that revealed a number of significant, but simple, operational changes that resulted in quick savings. Through this process, it was discovered that the HVAC system was operating in meeting rooms and public areas at night when the areas were unoccupied. A simple re-programming of the thermostats eliminated the unnecessary energy consumption, resulting in an immediate energy reduction. Furthermore, the implementation of a regular preventative maintenance program (including HVAC filter replacement, optimized HVAC scheduling, damper adjustment, and seasonal thermostat recalibration), is expected to save an additional 7-10 percent in annual energy consumption as compared to "business as usual," all while taking place within the context of the building staff's regular repair and maintenance responsibilities.

Based on the cost savings realized through the retro-commissioning process, HEI was able to undertake a whole-building lighting retrofit. This process involved replacing T-12 fluorescent tubes with more efficient T-8s, incandescent bulbs with compact fluorescent lights, and older magnetic ballasts with new electronic ballasts. In addition, occupancy sensors were installed in some common areas and private offices. Bundled together, these lighting measures resulted in whole-building energy savings of 10 percent, and the retrofit will pay for itself within 3 years.

HEI also installed controllers on the building's boilers to save energy when hot water is not being used. In addition, a variable frequency drive (VFD) on the kitchen's main exhaust fan and premium efficiency motors will help the building achieve continuous superior energy performance.

The Atlanta Marriott Norcross earned the ENERGY STAR by achieving an energy performance rating of 76. This increase in energy efficiency translates into real savings for HEI and a reduction of the hotel's carbon footprint. HEI has already reinvested the money saved in improvements to the Atlanta Marriott Norcross' infrastructure to ensure continued high energy performance and maximum guest comfort, while continuing environmental improvements.
