• Operating cost savings of more than $2 million per year;
• Water savings of more than 4 million gallons per year; and
• Greenhouse gas emission reductions of more than 16 million pounds per year.
Optimum Energy also is conducting site assessments of five Suffolk County municipal buildings, including a power plant that serves several buildings, an office tower, two court complexes, and the medical examiners building. Preliminary calculations predict implementation of OptimumHVAC in these facilities may result in greater than 2 million kWh of energy savings annually for Suffolk County.
“New York is leading the charge to more sustainable buildings with innovative programs such as New York City’s benchmarking, audit, and retro-commissioning initiatives,” said Nathan Rothman, founder and CEO of Optimum Energy. “As a result of those initiatives, our New York customers are very aware of the actual performance of their buildings. Implementing next generation solutions such as OptimumHVAC not only provides for significant benchmark improvements, it also makes solid business sense when you consider the cost savings. That is driving strong interest from our customers who won’t accept the status quo when it comes to energy efficient HVAC.”
According to the company, most projects are eligible to receive New York State Energy Research and Development Authority (NYSERDA) or Long Island Power Authority (LIPA) incentives totaling more than $2.6 million. These financial incentive programs combine with the region’s relatively high cost of power to provide a compelling return on investment. The average simple payback for these projects, which includes the cost of OptimumHVAC plus any hardware upgrades, less incentives, is just over two years.
OptimumHVAC is said to be ideal for New York commercial facilities equipped with centrifugal chilled water and/or variable air volume air handling HVAC systems due to the high percentage of partial-load operation. On average, buildings in New York only need to operate HVAC equipment between 90 and 100 percent of capacity less than 3 percent of the time per year, said the company. The rest of the time it’s possible to operate HVAC system equipment (including chillers, pumps, and fans) at variable (slower) speeds to save energy and maintain a comfortable environment. The OptimumHVAC software accomplishes this by automatically calculating the most energy efficient sequencing of HVAC system equipment based on real-time building loads, reducing energy use by up to 60 percent.
