Using Ancient Technology for Energy Efficiency

As far back as 2,000 years ago humans devised a way to create ice at night for use as cooling during the day even in desert areas of the planet!  The same principles of heat transfer used long ago are used today in a mechanical system known as Ice Storage Air Conditioning. The system uses ice for thermal energy storage to reduce energy used for cooling during times of peak electrical demand. The system works by creating ice at night or during non-peak energy usage and then uses that ice to cool the building during the day when that energy usage would be at peak energy usage rates.  This type of system reduces the amount of energy the building’s mechanical system uses and will result in a cost savings to the college.
