The Kimmel Studio is inside of the old Mason's building in the heart of Hollywood. Western Allied was hired as design / build contractors to renovate the HVAC system which had been short of capacity and audible through the wood structure roof. With no other area for equipment than the roof, we installed the quietest system that was possible using vibration isolation with 4" deflection springs and internally lined duct work that mitigated sound before entering the studio space. Our DDC control system has a special "SHOWTIME" mode which will bring on all cooling at constant volume for the duration of filming.
