Howard Hall Renovation

Baltimore, MD

The Howard Hall renovation consisted of three floors of phased renovation within this occupied academic/research facility.

The first phase of design consisted of the complete upgrade of the mechanical and electrical systems for the 4th, 5th, and 6th floors of the Howard Hall Building, encompassing approximately 90,000 SF of laboratory/research space for numerous medical research functions. Renovated spaces on the 4th and 5th floors contain both wet labs and computer-based dry labs in support of the University’s School of Medicine – Program for Human Genetics. The 6th floor renovation was a dedicated 12,500 SF Animal Care Facility, complete with a 10,000 SF Bio-Safety Level 3 (BSL-3) suite housing eight animal holding rooms and two procedure rooms.

Infrastructure upgrades included new 30,000 CFM 100% OA custom air handling units located on each floor to provide conditioned supply air to the laboratory spaces. In addition, (3) 75,000 CFM roof-mounted, custom energy recovery exhaust units were designed and installed to serve the renovated floors, as well as to backfeed the existing laboratory exhaust for the remainder of the building. This conversion included a complex phasing scheme to convert the existing exhaust system from individualized fume hood exhaust to a manifolded general exhaust incorporating an exhaust plenum over 200 feet in length at the roof, tied into the three energy recovery units. The work was accomplished with minimal downtime of the building occupants.
