Hamstrung for years by budget issues that did not allow the North Carolina Museum of Art (NCMA) to spend the money it needed to maintain the mechanical system, in 2005, the museum experienced variances in humidity of 30% in the winter and up to 60% in the summer. After careful review of the facilities, it was determined that ASHRAE Class AA environmental conditions could be achieved through an HVAC system overhaul. An added benefit of the upgrade would be energy savings totaling 57% or more.
