(a) The facility shall provide fully functioning heating and cooling systems adequate for the square footage of the facility. However, areas of a facility from which residents are restricted (e.g., mechanical rooms, storage rooms, etc.) are exempt from this requirement.
(b) The facility shall provide a fully functioning ventilation system adequate for the square footage of the facility.
(c) The facility shall maintain an alternate means of ventilation in the event that regular power is interrupted. The alternate means of ventilation shall ensure there is a mechanical means of bringing fresh air into and exhausting stagnant air out of all resident-occupied housing areas, such as placing an industrial-sized fan in front of an open door or window to bring in fresh air and placing another industrial-sized fan in front of another door or window to exhaust stagnant air.
(d) Documentation of any malfunctions or repairs made to the heating, cooling, and ventilation systems shall be maintained in the facility's maintenance log.
