2.2 Monitoring Temperature and Relative Humidity — NEDCC

IntroductionThe Environmental Monitoring ProgramMonitoring The EnvironmentThe Monitoring Program in PracticeEvaluating Climate and Collection NeedsHow to Improve The ClimateCollection materials are vulnerable to damage from their environment whether they are paper, wood, film, leather, parchment, or metal. While we cannot eliminate all of the causes for decay of our cultural records, we can significantly slow deterioration by managing the storage environment. Yet, managing fundamentals of the storage environment such as temperature and relative humidity is a challenging task, in part because day-to-day needs often take precedence over longer-term climate control activities. In reconciling various institutional needs, environmental monitoring is a necessity. Monitoring the environment is a foundational element of an overall preservation program and provides the baseline for managing the storage environment. The development of a monitoring program involves gathering information about the institution’s building and systems, determining the priority collections to the institution’s mission, and analyzing the needs and vulnerabilities of collections.
