The first phase included a new exterior and reworking the associated utilities to accommodate the new building envelope. The second phase incorporated a second floor and modifying the infrastructure to permit installation. The third and final phase included the fit out of the first and second floors to the required classroom and lab spaces. The renovations added 15 classrooms, 12 laboratories, makerspace, and collaborative areas for engineering students to gather and learn. JDRM Engineering designed the HVAC, electrical systems, and technology systems for the facility.
High bay HID lights were replaced with high bay LED lights to maintain the industrial look of the open space. 4” recessed LED ‘slot’ lights were installed throughout labs and much of the first-floor common space. Classrooms, primary located on the second floor, were installed with pendent mounted custom sized luminaires with multi-zone dimming controls and daylighting control capabilities where required per ASHRAE 90.1.
Specific power needs for all lab equipment, totaling more than 120 connection pieces of equipment, being relocated, or replaced with new equipment needed to be coordinated with the University. The building’s existing power infrastructure was repurposed, and new transformation was not required to accommodate the new construction.
The area of the construction area housed portions of a 15KV loop which needed to be relocation while maintaining the functionality of five 1000KVA-480V-3PH transformers feeding the building. The 15KV loop ran through locations that were to become new 2nd floor classrooms so a new 15KV route was established. The existing building housed Labs that could only sustain shutdowns less than two hours, so switchovers were performed during off hours with generators onsite.
The project’s chilled water system was connected to the existing campus’ chilled water plant after it was determined that the plant has capacity. The project’s hot water heating system consists of variable speed building distribution pumps and a hot water to steam heat exchanger. The steam is generated from the existing campus’ steam plant.
The supply air to the building is provided by multiple indoor air handling units. The classroom units consist of supply fans, return fans, hot water heating coil, chilled water-cooling coil, high efficiency filters, bipolar ionization, and outside air, return air and exhaust air dampers. The laboratory units also incorporate a steam humidifier and a runaround coil that exchanges energy with a coil in the exhaust airstream located on the roof. The supply air is distributed to the space via constant volume reheat boxes and variable air volume reheat. In addition, the control system connected to the existing Siemens web-based system.
The Technology consisted of structured cabling and raceways, limited AV working in conjunction with the owner provided equipment and the owner’s AV contractor, consisted of projector placement, sound reinforcement speaker’s placement, AV connectivity and specifying monitors for huddle spaces. The scope of services also included access control, security cameras, wireless access points and built out of ER/TR rooms to serve the renovated spaces.
