This facility included numerous energy conservation systems. The 26,000-foot glass line on the sunny elevations of the facility was equipped with dual-paned windows with a ¾"-glass float and a motorized automatic blind system. Additionally an ice production and storage system was installed. Ice is produced during lower utility demand, which reduces the need for conventional cooling systems operation during peak-demand periods. During the day, water from the man-made lakes is cooled through the coils of the ice plant, and then cycled through the heat exchanger of the building's cooling system. During evening periods when outside ambient air is cool, the warmed lake water is circulated through pop-up sprinklers, utilizing the evaporative cooling effect to reduce lake-water temperature. This results in lower water temperature at the start of the next day, reducing energy consumption during peak-demand times, saving both money, and the utility's required production capacity.
