The Museum of History and Industry’s (MOHAI) library and textile storage were experiencing elevated RH levels in spring and fall, and extremely low RH during Seattle’s rainy winters. With support from the National Endowment for the Humanities, MOHAI worked with the Image Permanence Institute to solve the mystery and develop a strategy to achieve an appropriate and sustainable preservation environment for the collection. This session explores this HVAC puzzle, common to many museums, through the varying perspectives of mechanical equipment, facilities, conservation, and collections experts.
