This project consisted of the total mechanical HVAC upgrade to Barton Hall, the electrical and computer engineering facility located on the Homewood Campus of the Johns Hopkins University. Barton Hall is comprised of 60,000 GSF of offices, classrooms, and laboratories, each in need of separate HVAC requirements.

An evaluation of the existing mechanical system determined that it was antiquated and beyond its useful life. The two (2) pipe fan coil system was upgraded to a four (4) pipe system to allow for simultaneous heating and cooling in separate areas of the building to satisfy the individual area needs. The existing cooling system was augmented with a VAV system to increase the capacity and provide more efficient cooling. The existing air handling units were evaluated and condensed into one larger more efficient unit to better serve the building loads.

Concurrent to the HVAC upgrade, the existing fire alarm system was redesigned to bring Barton Hall up to NFPA code requirements to provide enhanced safety for the students and faculty of the university.

Due to the time and space limitations the University established, the project was carefully planned for renovations to take place within a short time span to minimize disturbances during the academic year. The project was completed between the months of May and September, thus making the building available by the start of the fall semester.
