Howard County Community College in Columbia, Maryland expanded the campus with a new Allied Health Sciences Building. The project consisted of approximately 110,000 SF of new construction. The Allied Health Sciences Building consisted of a basement level and three floors of health education simulation suites, classroom, lecture hall and administration space.

The classroom and support areas on the first through third floors are served by packaged air handling units located in the basement mechanical room and on the roof. The administration areas are served by an air handling unit on the roof and the first floor lobby and lecture hall are served by an air handling unit in the basement mechanical room. The building has a dedicated chiller and boiler plant that serves the building and provides a level of chilled water redundancy for the existing Student Services and Visual Performing Arts buildings, as well as the Science and Technology building, which is in the middle of design, via underground piping. New domestic water, sanitary, storm and gas services were provided to the building. The chiller, boilers, emergency and normal power electrical equipment are located in the basement.

The addition, the Allied Health Sciences Building required replacing the existing medium voltage switchgear and upgrading the existing utility electrical service to the entire campus. The substation is located in the basement main electrical room of the Health Science Building and serves several 480Y/277V distribution panels for lighting and mechanical equipment. In addition, several 208Y/120V panels serve receptacles, fire alarm and miscellaneous equipment. An exterior, pad-mounted emergency generator provides power to egress lighting, one elevator, fire alarm and miscellaneous IT equipment in case of a normal power failure.

This project has been designated as a LEED Silver project and is on track for LEED Gold. LEED items include ground source heat pumps, solar domestic hot water, and energy recovery units.
