The following heating and cooling standards for new residential dwellings and new commercial buildings which utilize city utility services are established imposed.
(a) A new residential dwelling shall be equipped with storm windows and storm doors or other satisfactory window and door thermal treatment.
(b) Total heat loss, based on the ASHRAE Handbook of Fundamentals, or a new residential dwelling shall not exceed 35 BTUs per square foot per hour of floor area of heated finished living space, at a design temperature differential of 80°F with a maximum of one and one-half air changes per hour.
(c) New commercial buildings must be constructed so that heat transmission loss from 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°F.
(d) From August 1, 1978, through October 31, 1979, all installed air conditioning systems in all new commercial buildings new residential dwelling shall have an energy efficiency ratio of 7.0 BTUs or more of cooling capacity per watt hours input. On and after November 1, 1979, all such air conditioning systems shall have an energy efficiency ratio of 8.0 BTUs or more of cooling capacity per watt hours of input.
(e) From August 1, 1978, through October 31, 1979, all heat pump systems installed in all new commercial buildings and in all new residential dwellings shall have an energy efficiency ratio of 6.7 BTUs or more of cooling capacity per watt hours of input. On and after November 1, 1979, all such heat pump systems shall have an energy efficiency ratio of 7.5 BTUs or more of cooling capacity per watt hours of input.
