Loews Vanderbilt Hotel Achieves 22% Improvement in Energy Efficiency

Loews Vanderbilt Hotel has improved its energy efficiency by 22% and achieved a total energy cost savings of $328,250 over the past two years. The hotel has also set a goal to reduce energy use across all of its hotels by 20% in 10 years.

Through the Department of Energy’s Better Buildings Challenge, the Nashville hotel added updates to lighting and HVAC systems, guest rooms and building envelope.

In order for the Loews Vanderbilt Hotel to reduce energy consumption by 22% within two years, Loews upgraded all public-area lighting fixtures to LEDs, installed new direct-drive elevator hoist motors on seven passenger elevators, replaced outdated 750-ton centrifugal chillers with re-sized, highly-efficient 500-ton chillers, and installed a new, more efficient water system. The hotel also installed new variable frequency drives on the existing chilled water and condenser pumps in order to further enhance HVAC efficiency and replaced the water distribution media inside the cooling tower. And by enhancing and insulating the hotel’s façade and ballroom roof, the building’s overall R-value (insulation effectiveness) was improved by 20%.

To add to its commitment to energy efficiency, Loews also recognizes leadership among its engineering managers in every hotel nationwide, giving out the “Gold Wrench Award” to engineers who find energy saving solutions and contribute to sustainability goals.

Caesars is another hotel on the road to continuous improvement in sustainability. The company is working toward energy reduction goals of 25% by 2025 and 40% by 2030, measured on a per-square-foot basis against a 2007 baseline.

In 2015, Caesars initiated a comprehensive ventilation upgrade and chilled water plant optimization pilot at its Paris Hotel & Casino. The project successfully reduced peak electrical demand by 635 kilowatts and is saving more than 5.5 million kilowatt-hours per year. Economically, the project yielded a post-tax internal rate of return of 23% and is delivering over $440,000 per year to the bottom line. This helped earn Caesars the 2017 Environmental Leader Project of the Year award.
