Mechanical Solutions was selected to design/install the HVAC systems for World Wide Technology’s new headquarters building in St. Louis, MO.
The new building consists of seven floors, with more than 200,000-square feet of traditional commercial office and support space. We worked directly with the owner and design team to determine the best HVAC solution, balancing initial costs, maintenance costs, system redundancy/reliability, energy efficiency and performance throughout the building’s life-cycle. The heart of the HVAC system consists of six gas-fired rooftop units serving more than two-hundred and thirty zones through a common/loped duct distribution system. Furnished and installed twenty-two variable air volume units with SCR electric reheat, five fan powered terminal units with SCR electric heat, one DX fan coil unit, one indoor split system with associated condensing unit to serve the IT closets on each floor, two stairwell pressurization fans, two variable frequency drives, one elevator shaft pressurization fan, one variable frequency drive for elevator pressurization, one general exhaust fan, one air curtain with electric heat, fifty-five fire dampers with ductwork access doors, twenty-eight manual volume dampers, three motorized dampers, seven electric unit heaters, twenty-one sections of baseboard heaters, one electric cabinet unit heater, one hundred fifty-one air devices and galvanized ductwork for supply, return, and exhaust systems. The advanced building automation system offers redundant controllers and sensors for all critical applications, to ensure consistent and reliable system performance. Intermingled DX split systems offer redundant cooling sources for all critical IT and electrical spaces.
