Dulaney High School

BKM is serving as the MEP consultant for the replacement Dulaney High School project. This project consists of a multi-story approximately 345,000 SF new high school located on the same site as the existing high school.

The primary HVAC system is a four-pipe chilled and heating water system. Air cooled chillers and gas fired condensing boilers will serve as the primary cooling and heating source of the building. Vertical fan coil units (FCUs) located in mechanical closets will condition the classrooms. Ventilation air will be provided through rooftop DOAS (dedicated outside air system) units with energy recovery wheels and all DOAS units will have DX cooling and hot water heat. Other spaces sealed by the chilled water system include the administration area and the cafeteria. The administration area will be served by fan coil units & DOAS units similar to the classroom and cafeteria will be served by a four-pipe single zone VAV rooftop unit. The gymnasium, media center, auditorium, stage and community area will be served by packed DX rooftop units with hot water heat. New incoming water services will be provided and coordinated with the existing building services to meet the domestic and fire protection needs of the building. Due to the water pressure available, a fire pump will be included to ensure proper sprinkler coverage/pressure throughout the building. A new BGE gas service will also be provided.

Due to the size of the building two 4,000 amp (480 V) electrical service entrances are anticipated. The building will be equipped with a permanent generator to meet the life safety and optional standby needs of the school. A exterior mounted generator connection box will be provide to accommodate a portable roll up generator to meet the MEMA requirements. All new lighting will be LED with low voltage controls compliant with energy code requirements. Lighting will also be provided for the site and stadium.

The project will also include several facilities detached from the main building. These buildings are a maintenance building, greenhouse, concessions building and a stadium press box. Construction will occur in phases over a four year period to minimize the impact to the existing building/students.
