The solution was a 1,900 ton-hour ice storage system to minimize electrical demand during peak rate periods. AltieriSeborWieber performed a detailed economic analysis, commissioned by LILCO, to evaluate system performance and qualify the building for the LILCO business development tariff. The design of the system was complicated by the need for continuous occupancy and the year round needs of Swissair's reservations computer center.

In addition the system was designed with a low temperature air supply system to minimize fan energy. Air is supplied to ceiling mounted series fan powered terminals at 45oF.

The system also employed variable speed drives on all major air handlers and pumping systems. Chiller and computer air-conditioning heat was recovered for pre-heating of domestic hot water. The building closed circuit evaporative coolers were used in a water-economizer format to permit chilled water cooling service to the computer air-conditioning systems during cold weather.

To further reduce electrical usage ultrasonic humidifiers were specified for the computer air-conditioning systems.

On the electrical side, a 400-kVa gas fired generator was specified to reduce the building's dependence on LILCO power during peak period. The electrical system is capable of operating in parallel with utility power. Charging stations were provided in anticipation of the future needs of electric vehicles.

All of the above systems were managed by a state-of-the-art computerized building management system.
