    Sec. 18.11. Heating and cooling standards.
    (a) When a condominium building has a cooling system or heating system or both serving the entire building, including individual units, the association shall comply with the following standards with respect to the individual units in which people live:
        (1) During the cooling season, June 1 through
September 30, cooling systems must operate when the heat index exceeds 80 degrees Fahrenheit.
        (2) During the heating season, October 1 through May
31: (i) between 6 a.m. and 10 p.m., heat must register at least 68 degrees Fahrenheit when the outside temperature falls below 55 degrees Fahrenheit, and (ii) between 10 p.m. and 6 a.m., heat must register at least 62 degrees Fahrenheit.
    (b) When a condominium building does not have a building-wide cooling system that serves individual units, then the association shall provide at least one indoor common gathering space for which a cooling system operates when the heat index exceeds 80 degrees Fahrenheit. All occupants of the building shall have free access to that cooled space. As used in this subsection, "indoor common gathering space" means a room intended to be used as a place where multiple people can gather, such as a lounge, meeting or conference room, party room, or similar that can accommodate a cooling system. Any condominium building that does not have an indoor common gathering space shall be exempt from this subsection.
    (c) This Section only applies to associations in which the initial declaration limits ownership, rental, or occupancy of a unit to a person 55 years of age or older.
