Mechanical, electrical, plumbing, and fire protection engineering for the renovation of a 40,000 sq. ft., three-story office building. Existing partitions were removed and new electrical, plumbing, and HVAC systems were installed, as was a new elevator. The building employs a partial thermal ice storage system to provide approximately 50% of the required cooling. This system utilizes low-temperature air, whereby air is cooled by the ice to a temperature of 44F to 46F degrees, then circulated throughout the building. The ice makes the low temperature possible, and because the air is up to 10 degrees cooler than with a conventional air conditioning system, the air quantities are less and thus the size of the air handling system is reduced.
