The 18 million-square-foot CityCenter development along the fabled Las Vegas Strip teamed eight architecture firms for its combination of hotels, residences, and dining, retail, and public spaces. The project also is tackling sustainability on a large scale, targeting a number of LEED ratings from the U.S. Green Building Council, Washington, D.C.
Among the sustainable attributes of the project is a 8.5 megawatt natural gas co-generation plant that is slated to provide 10 percent of the project’s overall energy on site, reduce emissions, and provide all domestic hot water. Water conservation technology aims to save up to 39 percent in the projects’ buildings. Reclaimed water from the Monte Carlo property is used for dust control in the desert region and will save 2.4 million gallons of potable water.
More than 230,000 tons of construction waste has been reused or recycled. During the project, the Boardwalk Hotel was imploded and 80 percent of the structure was recycled into building materials for CityCenter or was sent elsewhere for reuse. Crushed blocks and mortar were used in dust abatement on the site and as aggregate in concrete and asphalt. Recycled glass and bathroom fixtures were wrapped in old curtains and carpets and then reused. In total, 95 percent of all construction waste was recycled.
The project uses Minneapolis-based Forest Stewardship Council-certified wood and low-VOC paints, as well as sustainably certified carpet. Each tower of the project is designed to reduce heat transfer and feature reflective rooftops, specially coated windows, and high-performance glass.
Marquees and signs will be energy efficient. Slot machine bases are designed to serve as floor air-conditioning units, providing ground-up cooling. The project is slated to open in December 2009.
