Johnson Controls recently unveiled its new York VRF solution, a benefit of the company’s recent Hitachi joint venture. The ductless and modular HVAC solution heats and cools multiple building zones to increase energy savings, improve occupant comfort, and lower construction costs. VRF features Hitachi’s high-efficiency compressors and is complemented by energy modeling and selection tools to measure and compare VRF to other HVAC technologies.
Johnson Controls launched the new York® Prestige™ rooftop units, which match the footprints of other manufacturers’ units. The new design reduces installation complexities and saves contractors time by eliminating the need for a curb adapter, which is typically required when a new unit does not identically match the existing unit footprint.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
