Buffalo, N.Y., Office Building Fulfills Cooling and Heating Wish List with VRF Zoning SystemLocated in the Village of Kenmore, N.Y., 2780 Delaware is a 21,000-square-foot, mixed-use building on Delaware Avenue, a historic corridor connecting Buffalo to its northern suburbs. Recognized in 2011 as the “Real Estate Development of the Year” by the Greater Buffalo Building Owners and Managers Association (BOMA), 2780 Delaware houses first-floor retail space with medical and professional offices on the second floor.
Challenge: Finding the Right HVAC System
In spring 2010, Iskalo Development Corp., Buffalo, N.Y., was finalizing designs for a new two-story office building at 2780 Delaware Avenue. Paul Bodhan Iskalo, founder, president and CEO of Iskalo Development, wanted high-performance HVAC zoning capabilities for the building, robust energy efficiencies, smart system controls and low noise from the compressors and fan coils. He was also looking for a system that would hold up to Buffalo winters.
Iskalo soon discovered that Mitsubishi Electric Cooling & Heating (Mitsubishi Electric) Variable Refrigerant Flow (VRF) zoning systems would fulfill his wish list. In the fall of 2010, the new VRF zoning system was installed by Greater Niagara Mechanical, Inc., North Tonawanda, N.Y. Company owner Sam Prezioso was impressed with the system’s benefits. “I like the efficiency of the system in cooling season as well as the ability to maintain interior comfort even in the winter months,” Prezioso said. Given the area’s northern climate, a key design condition was sizing the system for both cooling and heating so that a supplementary heating system would not be required. Both Iskalo and Prezioso liked the Mitsubishi Electric VRF zoning system’s extreme quietness and ease of installation, as well as its capability to simultaneously cool and heat different zones in the building. Prezioso also pointed out the system’s ability to heat during low temperatures, eliminating the need for natural gas heat, which tends to require more maintenance.
Results: Convenient Systems and Security Controls
Iskalo was pleased that his performance objectives for the building’s comfort system had been realized — reliable zoning and controls capability, energy efficiency, low noise and a sole source for heat. In reference to Mitsubishi Electric’s control system, Iskalo commented that “having the ability to control the building’s HVAC system, security doors and third-party energy-recovery ventilator remotely from our corporate office allows our property management staff to operate more efficiently and provide a higher level of service to our tenant customers. It’s a great tool for real estate developers, building owners, engineers and facility managers.”
