After construction already began, Johnson Controls presented a case for an enhanced central utility plant, which would be more sustainable than the original design, according to a Johnson Controls case study. Hospital officials agreed to the proposal and made Johnson Controls a dual prime contractor for the project.
“Because Phoenix Children’s involved us early in the process, we were able to offer a total package around their technical, service and maintenance needs,” Claudio Andreetta, Johnson Controls regional vice president, said in the case study. “By considering technology, design and layout, we are able to generate certain financial and operational outcomes.”
Now complete, the enhanced central utility plant reduces the hospital’s natural gas consumption by 70 percent. Additionally, the efficiencies save 5.6 million gallons of water each year, a plus for the arid Phoenix area. Further, Phoenix Children’s saves an estimated $570,000 annually thanks to the enhanced plant.
Beyond the cost and resource savings, the project also led to an incentive payment of more than $463,000 from Arizona Public Service as well as $3.6 million in funds from the federal Department of Energy.
