Murphy Company was contracted by Enterprise to complete the renovation of their five-story 350,000-square-foot office headquarters in the nine-month construction schedule. The HVAC system featured a central plant chilled water system with variable speed pumping for energy efficiency. The system’s airside was variable air volume with variable speed motor on the air-handling units. We installed two heat wheels to maximize energy efficiency.
The heating hot water system has six 95% efficiency boilers that serve fan terminals with hot water heat. The complete HVAC system was tied together with a direct digital control (DDC) control system, which managed space temperatures, and optimum start and stop of the system for energy efficiency. The plumbing system was 75% prefabricated at the Murphy Plumbing Prefabrication Shop. We used energy-efficient domestic water heaters and water-efficient water closets and urinals.
