This two-year project is focused on improving and increasing the capacity of humanities collections professionals to independently establish and maintain sustainable environmental management programs. In cultural institutions an environmental management team that includes both collections and facilities staff creates a structure in which the insights gained from environmental monitoring are actively used to inform environmental management. Webinars and workshops will provide essential knowledge and skills necessary for small, mid-size, and large institutions working to balance the preservation quality of collections environments with responsible building management and lower energy costs. This project has the potential to simultaneously improve the long-term preservation of humanities collections across the US while reducing the long-term costs associated with preserving those collections.
