Yet there are a number of reasons why hotels have been slower to adopt green policies. The buildings themselves often are highly leveraged, so builders are reluctant to add even a nominal additional cost, Quaintance says. Ownership of the buildings themselves are fractured: though a building may bear the name of Hilton, Marriott or Westin, it often is owned by a franchisee, large or small. In addition, much like a retail facility, a hotel operator is also subject to the behaviors of its users. "You don't control your entire environment," Heisterkamp notes. "Your guests do."

To meet their own goals, government and corporate meeting planners are beginning to ask more specific sustainability questions as they plan for locations, such as a facility's Energy Star score and the amount of waste being diverted.

To do so, developers are employing a combination of techniques from various other sectors--the windows and natural daylight in an office building, but the need for commercial kitchens that would be found in a restaurant. Not unlike a home, thermostats can be set to permit a range of temperatures which can help guide the guests to save energy, while motion sensors can cut power to unoccupied rooms, a technique found in newer office buildings. Light bulbs can be easily replaced with more efficient models. "There are a number of things you can do," McInerney notes.

Proximity also has an adjacent bistro, which allowed its developer to use a number of technologies as it achieved an unplanned level of sustainability. "We were surprised," at the Platinum level, says Quaintance. The goal had been to create a sustainable hotel, with LEED as a guideline. "Our goal was to consider sustainability with each decision. And with every decision, there was one more thing to consider."

[IMGCAP(2)]By using the latest construction technology and efficient materials, the Proximity uses 41% less energy than a conventional restaurant. Variable speed hoods in the restaurant uses a series of sensors to judge and adjust of the kitchen's needs. Hot water is heated by 100 solar panels covering the 4,000-sf roof, with geothermal energy used to power the restaurant's refrigeration equipment, saving water. Recycled wood is used for tabletops and trays, and high efficiency water fixtures are used throughout the guest rooms. Even the elevators capture the system's energy and feed it back to the building's internal energy grid. Abundant natural lighting and operable windows also improve both the efficiency and ambience of the hotel.

"I don't understand why most hotels don't have solar heating for water," Quaintance says, who plans to retrofit his other hotels accordingly. "It's a great investment." And in fact, the Hilton Garden Inn Indianapolis, a hotel owned and operated by Rosemont, Ill.-based First Hospitality Group, Inc., has requested a grant from the Indiana Department of Energy and Defense to install solar panels on its roof.

And other chains are going truly green, albeit slowly. The major chains are working sustainable initiatives into their franchise standards. "These are large companies, so the change will be incremental," Heisterkamp says.

This year, Starwood Hotels opened its first two ELEMENT Hotels, the first hotel brand requiring all of its hotels brand-wide to pursue LEED certification. The hotels use energy efficient appliances and lighting, and water-saving fixtures, low VOC (Volatile Organic Compounds) paints and carpets with up to 100% recycled content and anti-microbial carpet pads which improve indoor air quality for guests and staff. Guests driving hybrid cars are rewarded with priority parking.

The hotels are located in Lexington, MA, and Summerlin, NV. Future hotels are planned in Tempe, AZ; Denver; Orlando,FL; Tampa, FL; Atlanta; Chicago; Leawood, KS; Ewing, NJ; New York City; Cary, NC; Irving, TX; Ashburn; Chantilly, Herndon and Vienna, VA; Vintage Park (metro Houston), TX; Palmdale, CA; Arundel Mills, MD (Baltimore), Toronto and Abu Dhabi.

And future development can be helped by the extension of the Energy Efficient Commercial Tax Deduction as part of the Wall Street bailout bill passed earlier this month. In addition, the AH&LA is working with the USGBC to create a LEED rating system specific to the hotel industry, which could even help resale values in the future, McInerney says. Ultimately, though, it is the consumer who is forcing the industry by going green.

"It becomes a buyer's market, particularly for government and corporate procurers," Heistercamp says. "LEED provides a common framework. It really means I want to put my money where my beliefs are."
