Display cases, if well designed, can be used to control the environmental conditions (e.g. relative humidity and pollutants) around valuable and vulnerable collections, and can help reduce the risks of damage to the objects on display (e.g. from light, theft and vandalism). These controls, however, present designers with a challenge of maintaining several performance specifications while developing a display that highlights particular objects and tells their story. Due to the varying functions display cases may have to fulfill, many questions still persist about museum case design for designers, conservators and museum professionals alike, such as:
- Should I retrofit existing display cases and, if so, how?
- Are there sustainable approaches to display case design?
- Why can I not use certain materials? Are there design solutions to these problems?
- How tight is tight enough when it comes to air leakage? How do I measure it?
- When do I need extra materials in the case, like humidity buffers and scavengers? How much?
- What are the advantages of creating a microenvironment within the case, rather than controlling humidity and pollutants at the room level?
- Do new lighting technologies change the old rules about case lighting?
- How do I communicate my requirements to the other specialists involved in the design and fabrication of display cases?
Upon completion of this workshop, participants will have an increased understanding of many factors related to museum display cases, including:
- The effect of relative humidity, light and pollutants on objects, and mitigation of the related risks.
- Issues related to retrofitting existing display cases.
- Specifications for display case design and fabrication, based on the need of objects or lender conditions and budget allowed.
- Balance between preservation, access and visibility, as well as sustainability and cost.
