CaseHistories Re al-woRld solu t ions Energy Savings With Historic Overhaul A ccording to Brian Berard, AIA, LEED-AP, senior project manager for Savery Hall, University of Washington (UW) Capital Projects Offce, the mechanical, electrical, and plumbing systems in the building were operating well but they had exceeded their service life; they did not satisfy current code demands and were totally ineffcient. The 90-year-old building was in need of complete renovation. To comply with UW's design criteria and reduce energy consumption, during the predesign and schematic desgn phases, the team looked at a traditional variarble air volume (VAV) system without mechanical cooling. After all, Seattle's climate is mild. After further modeling and a natural ventilation analysis, it was evident that Savery Hall could not be adequately cooled utilizing natural ventilation alone. An alternative cooling system had to be selected. The team turned to VRF (Variable Refrigerant Flow) zoning systems. Berard and his team looked at multiple VRF technology systems and fnally selected one from Mitsubishi Electric Cooling and Heating Solutions. Berard says that the ingenious, multi-zone system was selected because of its energy-effcient, highperformance INVERTER technology; variable speed compressors; simultaneous cooling and heating capability; the extremely quiet indoor units; the lightweight, small footprint of the outdoor unit; and its capacity to orchestrate a mixed-mode solution employing both VRF and natural ventilation. Last but not least, Mitsubishi VRF systems require only a three-in. hole in the exterior of a building for piping and wiring, preserving Savery Hall's historic architectural integrity. "The University has been very happy Berard and the mechanical engineering consultants on his teem estimate that the Mitsubishi VRF system will reduce the energy consumption by 25 percent annually, with even greater savings obtained by incorporating natural ventilation, to help secure LEED Gold certifcation for Savery Hall. with the performance of this system and the quality of the equipment," Berard says. "I am delighted that we chose to go with Mitsubishi VRF zoning systems — the technology is rock solid. For a 90-year-old structure, I believe our mixed-mode strategy delivered a dynamic lesson in performance."
