  Material and product resilience is important in all types of building however health care facilities place additional strain on the selection of these components because of infection risk based on premature failure or inappropriate specification for the application based on the cleaning, sanitizing and disinfecting requirements of health care spaces. This change requires the Materials section with subsequent recommendations to the Operations and Indoor Environmental Quality sections. New references are added for the user to comply with specifically rated cleaning products. The third public review of this draft includes proper uses with new definitions and aligns the section headers with Standard 189.1-2023. The goal of the green cleaning and disinfecting plan is to identify disinfection products that are considered safer for use. The fourth public review address comments regarding the plan for use of disinfectants and cleaners as well as clarifying language addressing Scope 3 emissions.
