BHB engineers provided the lighting, power, fire protection, plumbing, heating, ventilating and air conditioning design for a new 60,000-square-foot, two-story academic classroom building. The new facility included multiple classrooms, offices, gymnasium, kitchen, and cafeteria. The new gymnasium and cafeteria area incorporated additional features so that it could also serve as an ICC 500 Storm Shelter.

The mechanical systems design included 42 gas-fired DX rooftop units to serve the new building. New ventilation system design was provided to serve the Storm Shelter during emergency operation. The new kitchen was provided with range hood exhaust system and make-up air unit to pre-treat all the hood make-up air. Controls for all new equipment were designed to be compatible with the existing campus-wide Building Control System.

The plumbing systems design included plans for domestic hot and cold water, waste and vent, gas, and fire protection systems. New domestic water service, fire service, and waste service were extended from new utilities brought to the new building site. Domestic hot water was provided by (4) 100-gallon gas-fired water heaters. The kitchen grease waste system was equipped with a 1,200 lb. grease interceptor. A new electric water heater was included to provide an independent domestic hot water source for the Storm Shelter.

 

The electrical systems design included a 2,000 amp, 277/480 volt power system. The building’s HVAC, large kitchen loads, and lighting loads are served at 277/480 volts. Step down transformers provide the 120/208 volts for general receptacle and kitchen appliance loads. Shielded transformers, double capacity neutrals, and isolated ground receptacles are provided to protect the building’s computer systems. The lighting system consists of dimmable LED fixtures with automatic controls to turn off the lights when they are not in use. Central battery systems provide power to emergency egress light fixtures for illumination of the pathways out of the building and for lighting and ventilation within the storm shelter during a normal power outage.
