PACE Collaborative provided mechanical, electrical and plumbing engineering services for the renovation design of Sandy Hall at Virginia Tech in Blacksburg, Virginia which is currently under construction. This anticipated LEED certified, 12,823 gross square foot building, was originally constructed in 1924 and has not had any major improvements or renovations since the building came into service. The improvements include upgrades to the HVAC, electrical and plumbing systems as well as improvements to the exterior envelope, hazardous material abatement, and minor structural improvements.  The mechanical design included the use of active chilled beams which allowed the central station air handler to be significantly downsized as compared to a conventional VAV air handling system.  The electrical system was designed with energy efficient LED light fixtures and a state-of-the-art lighting control system which includes the use of occupancy sensor to turn off general use light fixtures as well as convenience receptacles to further reduce energy use when the building is unoccupied.
