Agnew Associates replaced the variable air volume, dual-duct HVAC system with air handling units and air distribution. A DDC energy management system, high-efficiency fan motors, and the variable flow pumping were retrofitted to systems throughout the building to reduce energy costs. AAI also designed a combination standpipe/automatic sprinkler system to upgrade the fire protection system. A new 1950 GPM, 150 horsepower fire pump was designed to feed the system. Agnew Associates determined that the existing humidification system was not functional, so steam humidifiers were installed in the new air handling units. AAI replaced the humidifiers in the existing air units to provide humidity control throughout the building.

Agnew Associates designed new electrical systems for the entire renovated area. This included adding new lighting, power, communications raceways, and a new fire alarm system.

The new lighting system included high-efficiency lighting fixtures designed to provide the lowest available watts-per-square-foot ratio. Agnew Associates also added a digitally controlled lighting control system to the library’s large, public areas.

The new power distribution system allows computer connections at virtually all desk spaces in the library. The new distribution system started with a 4,000 amp, 480-volt electrical service in the existing basement of the facility. Agnew Associates added new power distribution panels on each floor to provide power to the large computer load the facility uses.

The firm included extensive data and telephone distribution to all desk areas of the facility and integrated the computer system into the campus’ fiber optic distribution network.

Agnew Associates provided the following services: An energy study, HVAC design, lighting, power, and communications system design, construction documents, and construction administration.
