While the Sheraton Waikiki is a beautiful destination for visitors and locals alike, the hotel works hard to meet sustainability goals through a number of energy efficient initiatives. HI Now host Kanoe Gibson went on a tour to see the how the hotel is implementing these.

The Sheraton Waikiki is a huge property with 1,636 rooms. That’s a lot of guests, and it takes a lot of energy to power all those rooms!

“For the Sheraton Waikiki, our sustainability goals for the whole Marriott Corporation is critical,” says Eric Au, area director of engineering and facilities. “Over the last 20 to 30 years, we’ve invested a lot of time and effort into our sustainability goals.”

In the hotel’s guestrooms, you’ll find things like low flow plumbing fixtures, smart thermostats that have motion and door sensors networked together, tinted windows, and even LED lights throughout the property. As guests make their way around the hotel, they’ll also be using energy efficient elevators.

However, most recently, the hotel has installed a cogeneration plant. The system is similar to an onsite gas generator that produces electricity. It reuses the waste heat to produce hot water, heating of the pool and pre-cool chiller with absorption chiller. It’s a reliable system, it saves energy, and it’s all about sustainability and the future generations.

“Overall, saved on energy efficiency, but also the reliability of this hotel.” says Au. “Technology is very important. If you look at our guests, that’s kind of what they look for in hotels.”

In the future, the Marriott Corporation hopes to reduce its electricity and gas usage at all its hotels. To do this, it hopes to explore

photovoltaic energy, waste to energy (generating energy in the form of electricity), food digesters, gray water recycling, green roofs, and wind generation.
