Case Study: Tustin Youth Center Cut Peak Power Costs By 90% With Thermal Storage AC
by Dr. Marcel Christians, Co-COO, Ice Energy
As summertime temperatures increase, air conditioners work overtime, straining the grid to peak demand levels and making everyone a lot less comfortable. Furthermore, air conditioning systems running during the hottest part of the day draw the most power. At the same time, they experience degraded comfort cooling performance. In 2017, the Youth Center in Tustin, which had 20 year old HVAC equipment, was spending $19,800 on their electricity bill alone.
27.5T of aging, inefficient air conditioning units were replaced with two brand new Ice Bear 30 Thermal Energy Storage units as well as 27.5T of new Carrier packaged units. The Ice Bears take over cooling from the power-hungry HVAC equipment every day from 2PM – 6PM. During that time, the Youth Center is cooled exclusively from the Ice Bears. At all other times of the day, the packaged units work as normal.
Despite the extreme summer heat, which drove temperatures above 100˚F, installed Ice Bear units worked flawlessly. The Ice Bear 30 units, combined with the new HVAC delivered $4,000 in savings year-over-year, a 20% reduction in the yearly cost of electricity. Demand dropped by up to 16kW during peak hours, which translates into up to 37% decrease in monthly demand charge costs.
The Ice Bear 30 units are covered by a bumper-to-bumper zero-cost 20-year service contract, while the new HVAC equipment lowers Tustin Youth Center’s on-going O&M costs.
