The U.S. Green Building Council recently granted the City of Phoenix’s Glenrosa Service Center a LEED® Silver rating. The 21,933-sq.-ft. multiuse service and maintenance facility, designed by Williams + Paddon Architecture of Roseville, Calif., and built by Wespac, makes up the first phase of the Glenrosa master plan and provides administrative and maintenance facilities for several city departments. Built on a remediated brownfield site, the building was constructed using processes that allowed diversion of more than 75 percent of its construction waste out of the waste stream. The new center incorporates an HCFC-free chilling system, waterless urinals, and other strategies and techniques for reducing water use by 40 percent, and also dedicates 25 percent of its parking exclusively for alternative vehicles. Glenrosa Center is the first city building to employ an underfloor air distribution system. Additionally, 91 percent of task areas have daylight and access to outdoor views.
