Project Information:

In lieu of a total HVAC system replacement, the ductwork and AHU can be replaced for relief of the issues that mold in the ductwork may be causing.

Remove the existing air handler and ductwork, replace with new properly sized AHU and condenser, and externally insulated ductwork. The ductwork replacement will require extensive drywall repair as most of it is behind the wall surface. Once completed, the same system layout will exist, the basement, first and second floors will be served by the HVAC system and the 1,650 sqft third floor will continue to use the existing DX window units. In the lower level, main feeder conduit is connected to the ductwork so conduit removal and relocation will be necessary.

The existing DX condenser is rated at 15 tons cooling capacity and the AHU is rated at 6750 cfm. These units will have to be replaced as the current excess cooling capacity will cause the system to short cycle preventing maximum dehumidification of the air. The ductwork is old and part of the mold situation may be caused by condensation on the external ductwork surfaces. The new ductwork will alleviate this problem.

The major positive impact of a HVAC renovation would be the improvement of the indoor air quality. That there is visual evidence of mold and built up dirt and grime on the systems internal surfaces indicates that air quality has been suffering for a long period. These repairs to the system will increase its ability to control excess humidity and will reduce the damage humidity causes to interior finishes and property. The continued growth of mold, the increase in dirt loading within the system and the inability to control interior humidity will cause the indoor air quality to worsen.

These funds will allow the University to address these deficiencies at the Coates Building .
