OVERVIEW. Loftus designed all mechanical, electrical, and structural systems for this state-of-the-art 106,000 sq. ft. $36 million office building. Innovative design concepts were used throughout this building including rain water recovery, radiant cooling, vegetated roofs, waterless urinals, and low flow fixtures. Due to the highly efficient envelope and systems design, the chiller capacity could be downsized to only 180 tons. That’s 600 sq. ft./ ton as opposed to the typical office building tonnage of 300-350 sq. ft./ ton.
A 500kVA generator was included in the building design. Fuel source for the generator is natural gas with automatic change over to propane. The generator provides continuous power for life safety requirements, security, 6,000 sq. ft. computer room/data center/ communications hub, selected government functions, and the executive offices. The Building Management Systems sequentially adds and strips loads on the generator. A 1250kVA unit substation included in the building design provides power to the building. Redundant 4160 volt feeders provide power to the unit substation.
Construction inspection was provided throughout the construction period to ensure compliance with contract documents, LEED requirements and site Environmental Health and Safety Standards. This project exemplifies Loftus’ ability to design a complex LEED building as well as supervise construction.
