The construction of ice storage systems is no more difficult than conventional cooling systems. Finding a space for the ice tanks is typically the most difficult aspect of the project. The space required is about 1/2% of the conditioned space for typical applications which is similar in perspective to the space required by a water heater in the average 2000 sq. ft. home. The cost of ice storage systems when designed as part of a new system or as part of a cooling system replacement is not so costly. Payback is typically less than 3 years in most place and a little more in urban places due to higher labor and land costs. Projects do not have to be huge. Ice storage biggest market is suburban schools. On these projects, many times the incremental costs are ZERO as the ASHRAE Journal article, TES Myths, points out here: http://www.calmac.com/whatsnew/a6maccracken1.pdf Morgan Stanley’s Westchester County offices just installed a new cooling system on Fifth Avenue as well as Goldman Sachs. The cost was about $3 million. There must also be space to hold the tanks. However, it is large companies that consume so much energy, and in the end, the system will pay for itself. “The construction of one of these systems is long, costly, and difficult.”
