Our design incorporated a number of sustainable technologies, including a 250-ton water-cooled chiller and cooling tower that reuses HVAC condensate, high-efficiency hot water boilers with hot water reheat, and a variable air volume system with fan-powered boxes. The building's fire protection system consists of a wet-pipe sprinkler system, zone control valve assemblies, standpipe hose connections, reduced pressure zone double detector check valve assemblies, and a new fire department connection.
