The COVID-19 pandemic has changed how people look at the built environment, whether at home, at workplaces, in schools, or in public places. This course will describe how these changing views are directly impacting the ways that buildings are being designed with architects and other design professionals stepping up to address changing criteria with innovation and an enhanced focus on health, safety, and welfare issues. Within this changing situation, large operable glass walls have emerged as a durable, flexible, and sustainable solution in many different types of buildings.
