The COVID-19 outbreak has made the role of a building’s health performance more than a nice idea; it has made it fundamental and essential.  In the case of public health emergencies two elements are key according to the WorldGBC: prevention and control. The ability to contain the epidemic is of utmost importance, particularly in times of enforced social isolation, with residential buildings becoming the primary location for both habitation and work, when possible. Community and building-based prevention and control strategies require measures such as self-isolation, community management, natural ventilation, elevator disinfection, environmental cleaning and more. Current green building criteria, e.g. the newest national standard for China in the Assessment Standard for Green Building (ASBG) from the WorldGBC as of March 2019, takes into account new applications and concepts in building technology with the stated goal of ensuring safety, durability, health, livability and accessibility for occupants of all ages. ASGB requirements, when combined with digital benchmarking, ensure that occupants receive natural ventilation, indoor disinfection and gathering avoidance. Monitoring quality levels and information distribution are two areas that can only be achieved by comprehensive data gathering and the proper application of digital solutions. In times of pandemic isolation, buildings become areas of both living and working with residents spending the vast majority of their time indoors. It becomes therefore even more essential that buildings can guarantee a stable and healthy environment.
