Control recommissioning in existing buildings presents an excellent opportunity to not only save energy, but to fix operational deficiencies and work with the building’s occupants to reduce complaints.
Heating and cooling upgrades for a preparatory boarding school nestled among the trees in Pottstown, PA, wove together the best of 1950s innovation with today’s energy standards
Greenheck says its new Model SWD is the industry’s first direct drive, backward-inclined utility fan to utilize an electronically commutated (EC) motor.
Schneider Electric has introduced a new drive that combines the Lexium 32 servo controller and the Lexium BMH servo motor into a single unit. The servo controller is installed directly in the machine as opposed to the control cabinet, which reduces the installation effort and eliminates the need for shielded motor cables.
Johnson Controls has released the York® Predator Ultra High Efficiency Packaged Unit. The company claims the combination of the unit’s two-stage compressor, variable-frequency drive , high-efficiency indoor/outdoor coil and premium-efficiency indoor/outdoor motor combine to deliver the highest AHRI-listed efficiencies in the industry and reduced energy use up to 18.1 SEER and 14.35 EER.
This project team left nothing to chance when it came to designing a five-story mixed-space facility for a Chicago gaming company. They also dealt a full hand of space-specific tactics: upgraded DX units, a dedicated variable-speed kitchen exhaust system, underfloor air, and better motors and drives improved the odds for efficiency. Pull the handle on this project story to get to the payoff.
The city of Côte Saint Luc in Quebec recently opened its new Aquatic and Community Centre with a cost of $18 million. While this may seem like a hefty price tag, the city will be saving millions of dollars on energy costs, thanks in part to the center’s HVAC system.
Today, many state institutions of higher learning and healthcare facilities face reduced budgets, aging infrastructure, and rising energy costs. According to the EPA, colleges and universities spend close to $2 billion each year on energy. These institutions are seeking innovative ways to renew facilities, improve energy efficiency, and reduce energy costs. One option gaining some renewed momentum is the Energy Savings Performance Contract (EPSC).
Identifying motor retrofit opportunities in cooling towers, air handlers, exhaust fans, and
circulating pumps reflects the no-stone-unturned strategy Rutgers employs in energy management.For those motors, boiler upgrades, and future projects, the university regularly seizes on multiple incentives opportunities — ranging from utility offers to good old-fashioned intraschool competition — to teach efficiency in action.
