Las Vegas hotel wins American Architecture Award

The award was presented to the Aria Resort and Casino in Las Vegas, which saves 30% more energy than similar buildings.


CityCenter’s Aria Resort and Casino in Las Vegas received an American Architecture Award from the Chicago Athenaeum Museum of Architecture and Design and the European Centre for Architecture Art Design and Urban Studies, announced Robert Sedlak, senior vice president of engineering firm WSP Flack + Kurtz.

WSP Flack + Kurtz provided mechanical-electrical-plumbing, fire protection, and telecommunications services for the project. The facility was the largest hotel in the world to achieve a U.S. Green Building Council LEED-gold rating. The 3.8 million sq ft complex is the tallest structure in CityCenter, the world’s largest LEED-rated development.  The sustainable design technologies that WSP Flack + Kurtz designed led to a 30% improvement in energy efficiency compared to a similar building meeting the minimum code requirements, an estimated savings of 31 million gallons of water each year, as well as an improved indoor air quality in the casino through the use of a displacement ventilation system. 

“What was so rewarding about the project was the extent to which we collaborated with the architect,” says Mr. Sedlak.  “We were able to play a major role in the design process, working closely with Pelli Clarke Pelli and the entire architectural team.
