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.
This matters because the rigid standards are "devastating the field," according to Getty Conservation Institute senior scientist Michał Łukomski, particularly for smaller institutions that cannot afford the energy bills. The guidelines also create inequity in art loans, disadvantaging museums in non-temperate climates. As the art world confronts its environmental impact, a growing movement advocates for more flexible, sustainable practices that balance conservation needs with energy efficiency and global accessibility.
