Chabot-Las Positas Community College District Achieves Sustainability Goals with CALMAC’s IceBank
CALMAC’s energy storage systems significantly reduce the district’s peak-demand energy consumption
Fair Lawn, N.J. – September 7, 2011 – CALMAC, a leader in energy storage systems, has provided its IceBank thermal energy storage systems to both campuses of the Chabot-Las Positas Community College District (CLPCCD), located in California’s Bay area, to help the district reduce energy costs and comply with the sustainability guidelines adopted by the district. Southland Industries designed and built central heating/cooling plants that incorporated CALMAC’s ice storage technology to help achieve the district’s sustainability goals while saving the district more than $200,000 and 1.1 MW per year in energy costs and consumption.
Faced with spiraling energy costs and mechanical systems that were outdated, the school district was looking for a way to reduce its energy consumption, greenhouse gas emissions and cooling costs. To do so, the district decided to adopt aggressive sustainability guidelines. To meet their goals, the district focused on establishing high-performance buildings for the campus and designing all their buildings to meet Leadership in Energy and Environmental Design (LEED) certification or higher. This path led the district to applying energy storage technology.
The CLPCCD district implemented two centralized heating/cooling systems with chilled and hot water underground looping. Each site used high-efficiency hot water boilers, CALMAC’s IceBank® thermal energy storage tanks and high efficiency chillers from Trane, a leading global provider of indoor comfort systems and services and a brand of Ingersoll Rand. Southland Industries designed and built the system to provide reliable comfort and drastically reduce peak-demand energy consumption for the district. The energy storage system creates ice at night, when energy is less expensive and renewable energy sources most abundant. The ice is then used the next day to cool the building, leading to significant annual energy cost savings and lower greenhouse gas emissions associated with peak demand avoidance.
As an added benefit, the use of ice throughout most of the year during the daytime reduces acoustical issues with a central utility plant. The ice storage option would also require a smaller indoor footprint for the mechanical room and would allow reusing an existing building vs. building a completely new central plant facility. CALMAC IceBank tanks were chosen for their unique modularity which makes it very easy to allow for future expansion while providing system reliability.
“Our district has made a strong commitment to reducing our carbon footprint, and this project shows how committed we are to this goal,” said Jeff Kingston, vice chancellor of Chabot-Las Positas Community College District. “Ice storage offered a solution to our district’s operating and energy woes. CALMAC’s IceBank tanks have allowed us to reduce our peak-demand, energy consumption, carbon footprint and our operating costs. It’s been a great addition to campus.”
“Our nation’s educational system is truly leading the charge to embrace green design and create a network of more sustainable and high performance buildings,” said Mark MacCracken, chief executive officer of CALMAC and chair, USGBC. “We are happy to play our part in this great undertaking and I hope other industries follow suit.”
CALMAC Manufacturing Corporation is transforming how energy is used at buildings to the time energy is used. Widely recognized for promoting peak energy conservation and energy cost savings CALMAC is a member of the Electricity Storage Association (ESA), United States Green Building Council (USGBC) and now the California Energy Storage Alliance (CESA). CALMAC is the manufacturer of IceBank® Energy Storage equipment with over 4,000 Ice Storage installations worldwide. IceBank systems are a valuable component of the smart grid, enabling energy, including renewable wind energy that mainly blows at night, to be efficiently stored for use during periods of high demand.
