Our team worked with the US EPA to provide a state-of-the-art HVAC building infrastructure for their Andrew W. Breidenbach Environmental Research Center (AWBERC) Research Laboratory facility. This allows an increase in the lab-to-office ratio and adds flexibility / redundancy to their current system. Services included renovation and upgrade of existing facilities as required. Through project management, we minimized research shut down time and interruption to ongoing research during construction. Work included phasing analysis, energy modeling, complete replacement of all air handling units, supply and return ductwork, laboratory exhaust and renovations of existing lab spaces over a multi-year schedule. The design increased the flexibility and redundancy of the system to minimize downtime and allow a marked increase in energy efficiency.
