The Hospitality sector includes more than 4 billion square feet of floor area nationally, encompassing nearly 5 million guest rooms. Hospitality partners represent 1 billion square feet, or 24% of the hospitality sector’s total market floorspace. Every year, the hospitality sector spends more than $7 billion on energy. If every hospitality property in the US reduced energy cost by just 10%, the sector would save $730 million annually.

Featured Solutions

Loews Vanderbilt Hotel Showcase Project
Loews implemented energy projects at the Vanderbilt Hotel due to its significant savings potential and outdated facility equipment. The implemented energy conservation measures resulted in 22 percent savings.
Solar PV has the potential to provide significant benefits to hotels by way of attracting guests and, more importantly, reducing operating costs. For more information on solar PV evaluation, visit the Renewables Integration Technology Solutions page.
The Venetian, The Palazzo, and Sands Expo are a combined property and metered as a single campus, making this site an ideal target for energy efficiency upgrades and improvements. Las Vegas Sands Corp. identified a number of energy and water efficiency upgrades for its large Las Vegas campus; these have been underway since 2014, and are expected to be completed in 2017. The completed measures have already resulted in 22% energy savings.
Loews Score Card Solutions at a Glance
Loews Hotels & Co. developed a Score Card tool to evaluate physical and operational performance across their building portfolio. This tool provides accountability for the engineering staff, who are tasked with meeting the company’s corporate sustainability goals, and helps direct capital investment in renovations and upgrades.
This technology roundtable facilitated discussion around evaluating and implementing emerging technologies in commercial buildings. Hospitality Better Buildings partners and National Lab representatives shared their experiences with technology verification and pilot projects.
