Waikiki Beach Marriott Resort & Spa has been awarded the 2008 Energy Star seal of approval by the Environmental Protection Agency in partnership with the U.S. Department of Energy, the fourth time in the past five years.

The hotel scored 81 on its performance, the highest rating it has ever achieved out of a possible 100.

"We are honored to receive the distinguished Energy Star designation once again," said Chris Tatum, general manager of Waikiki Beach Marriott Resort & Spa.

The 1,310-room resort just completed a $28 million green guest-room renovation project to its oceanfront Kealohilani Tower.

Eco-friendly highlights include: Compact fluorescent lightbulbs in every guestroom; efficient chillers for air-conditioning; Inn Comm Temperature control thermostat; Air-conditioning sensors in guestrooms that turn off the air-conditioning when the lanai door opens; tinted lanai doors in every guest room and public space to help reduce the heat load as well as the demand for increased air conditioning; low-flow toilets and shower heads; automatic sensors for toilets and sinks in public restrooms.

The resort also continues its extensive energy conservation and recycling programs.
