Singapore Resort Increases Margins with Energy Efficiency Efforts

Marina Bay Sands Energy ManageInstalling key-card-based energy management systems in hotels result in energy reductions between 20 and 30 percent. According to a Rocky Mountain Institute (RMI) blog post, this only scratches the surface of the money-saving potential that the hotel and hospitality industry can achieve through energy efficiency retrofits.

To illustrate the effectiveness of comprehensive energy retrofit efforts, Carbon War Room teamed up with KPMG Climate Change & Sustainability Services in 2013 to develop an energy efficiency case study on the Marina Bay Sands integrated resort in Singapore.

Marina Bay Sands has three building towers that house 2,561 rooms and suites and five levels of expo/convention facilities. The resort is also home to more than 300 retail outlets, an event plaza, casino, two theaters and a museum. In its first full year of operation in 2012, the resort’s baseline energy costs exceeded $100 million.

Since 2012, Marina Bay Sands has invested over $9.43 million in energy-efficiency projects.

The resort linked its electronic booking management system to the building management system so that HVAC systems turn on automatically one hour before an event and turn off one hour after the event. In 2013, the system saved the hotel more then 790,000 kWh of electricity.

In 2012, Marina Bay Sands replaced light bulbs in the hotel corridors and guest rooms with LED lights. It did another round of LED lighting retrofits in 2013, replacing bulbs in hotel elevator lobbies and elevators; loading docks; exhibition halls; casino; garage; theater; retail, meeting, incentives, conference, and events areas; and back-of-house areas, resulting in annual savings of more than 11 million kWh.

Also in 2012, the hotel installed passive infrared occupancy sensors in the walk-in freezers, housekeeping closets and back-of-house offices. In 2013, the resort installed more than 500 occupancy sensors in the convention center’s meeting rooms and bathrooms, and upgraded the pressure and temperature sensors in the chilled water pumps and air-handling units. The operational savings from the second phase of the installation of the sensors was over 2.9 million kWh annually.

Energy-efficiency projects at Marina Bay Sands have driven 11 percent energy savings with a payback of less than two years. To date, the resort has covered its investments, achieving more than $9 million in annual savings.

Marina Bay Sands is part of the Las Vegas Sands Corp., which has established an environmental strategy called Sands ECO360°. At the property level, Marina Bay Sands has a dedicated sustainability team, which is tasked with executing the Sands ECO360° strategy and taking advantage of energy-efficiency opportunities.
