Biotechnology institute facility

Facts and figures

• 104,000 sq. ft. office and laboratory space
• Four rooftop units (RTUs) ranging from 50 to 75 tons

Challenges

The client set high performance and sustainability goals for their new building. The commissioning of the new construction building systems required system interconnection testing and validation as well as functional testing involving multiple construction trades. The construction is concrete framed separate wings with punched openings in precast concrete panels and a high central lobby framed with heavy laminated wood columns, beams and deck, with exposed steel framing supporting an exterior aluminum curtain wall. The building is equipped with four rooftop units (RTUs) ranging from 50 to 75 tons, three of which are equipped with energy recovery ventilation in the form of heat wheels. The RTUs are packaged units and include natural gas heating and DX cooling. The RTUs serve various VAV boxes and fan-powered boxes throughout the facility. The vast majority of the terminal boxes are equipped with electric reheat. Exhaust fans located on the roof provide ventilation to bathrooms and fume hoods. Ductless split systems are used to cool electrical and IT rooms. The building uses 100% LED interior lighting controlled by wall switches and occupancy sensors; metal halides used in the parking area and LED bollards for the walkways are controlled by a photocell.

Solutions

After performing design document and submittal reviews, our team conducted construction inspections and commissioning coordination, then commissioned the following systems: air handling units, terminal units, exhaust system, space pressure control, lighting control and the building automation system.

Outcomes

Post-commissioning, our team also performed operation and maintenance training and conducted a site visit for warranty inspection. Additionally, we also oversaw the LEED certification process for the project.
