Why ‘devastating’ climate control rules for museum collections need a rethink

Museums are rethinking decades-old climate control standards that dictate strict temperature and humidity ranges for preserving collections. These guidelines, originally based on 1970s research for paintings in London, have been widely adopted globally despite being designed for temperate climates. Conservator Caitlin Southwick of Ki Culture argues this is a "big misunderstanding," as the standards were never intended for diverse collections like stone in Brazil or tapestries in Italy. Climate control systems now account for 60-70% of a typical museum's energy consumption, creating high costs and carbon footprints.
