It's a luxury destination for visitors to Singapore and the second most expensive building in the world, but even the opulent Marina Bay Sands resort has been able to reap the benefits of improving its energy efficiency efforts, Energy Manager Today reports. There are a number of measures that businesses in the hotel and hospitality sector can take to reduce their energy usage and, as a result, increase their margins. For example, studies have shown that installing energy management systems that use key cards can reduce consumption by up to 30%.

At Marina Bay Sands, the resort's 2,561 hotel rooms and multiple convention facilities - not to mention its theatres, museum, casino and 300 retail units - cost owners more than $100 million in energy bills in its first year of opening back in 2012.

Since then, it has shrewdly invested almost $10 million in projects to help improve its energy efficiency, with the help of Carbon War Room and KPMG Climate Change & Sustainability Services.

Changes ranged from replacing light bulbs with LED ones, to connecting the electronic booking management system to the building management system, so that heating and air conditioning technologies activated one hour before an event, and would switch off one hour after it had finished. This move alone saved in excess of 790,000 kWh of electricity in just 12 months.

Occupancy sensors were also installed over a two-phase period - firstly in 2012 in the resort's back-end offices, housekeeping storage areas and walk-in freezers; and secondly in 2013, with more than 500 occupancy sensors installed in meeting spaces and bathrooms within the convention center. This latter phase included updating the sensors that regulated the pressure and temperature in chilled water pumps and air-handling units, and resulted in a saving of over 2.9 million kWh per year.

But most importantly for owners and investors the resort has now seen a significant return on investment within the space of just two years, seeing annual savings of over $9 million.
