Multiple Chemical Sensitivity (MCS): The Controversy and Relation to Interior Design

Abstract

It is important for designers to become knowledgeable on multiple chemical sensitivity (MCS) as it relates to indoor air quality (IAQ). It is also important to design spaces and specify materials for the built environment that promotes good IAQ. MCS is a condition in which a person reports sensitivity or intolerance to a number of chemicals and other irritants at very low concentrations (EPA, 2003). Within the medical community, MCS has been controversial, and still is today, regarding its name, definition, diagnosis, and treatment. Some physicians consider MCS a psychological illness or phenomenon, while other physicians and clinical ecologists treat patients with MCS. However, research indicates that many individuals have become ill from chemicals emitted from materials within interior spaces. A consensus on MCS within the medical community is essential. The relevance of MCS for the design community is that many materials used in building construction, interior finishes and furnishings, and products for installations contain chemicals that may trigger MCS. Therefore, it is essential that designers specify safe, healthy materials. Since many designers (architects and interior designers) are working to improve IAQ, they could take the initiative for change by working collaboratively on research with the medical community and individuals with MCS; by educating other designers about appropriate product specifications; and by becoming a legislative advocate.
