Certificates of compliance required by section 4-902 of this article shall certify that the following heating and cooling standards have been met where applicable:

(a) New residential dwellings shall be constructed so the total heat loss, based on the ASHRAE Handbook of Fundamentals does not exceed 35 BTUs per square foot per hour of heated floor area of finished living space, at design temperature differential of 80 degrees Fahrenheit with a maximum of 12 air changes per hour.

(b) New commercial buildings shall be constructed so heat transmission loss of heated areas, based on the ASHRAE Handbook of Fundamentals, does not exceed 35 BTUs per square foot per hour of floor area based on a design temperature differential of 80 degrees Fahrenheit.

(c) The EER of all air conditioners in new residential dwellings and new commercial buildings on and after January 1, 1978, shall be not less than 7.0; the EER of heat pumps in such structures shall be not less than 6.7.

(d) The EER of all air conditioners in new residential dwellings and new commercial buildings on and after January 1, 1979, shall be not less than 8.0; the EER of heat pumps in such structures shall be not less than 7.5.

(e) In the case of a new residential dwelling or new commercial building which is heated and/or cooled in only a portion of the structure, the requirements of this section shall apply only to the heated and/or cooled portion of the structure, and service will not be continued unless in compliance.
