§ 84-a. Additional supervision and regulation of housing companies. The commissioner shall require that every company file with him, within six months of the effective date of regulations implementing this section and in such format as the commissioner shall prescribe an energy audit report which identifies potential energy-saving building improvements, including alterations, modifications and adjustments to the building structure, heating, cooling, lighting and ventilation systems; their relative costs; potential energy and cost savings; and simple payback periods, which for the purpose of this section shall mean that period of time within which the estimated cost of such improvements, exclusive of the cost of capital, would be recovered from the savings generated by reduced energy consumption resulting from the improvements. The energy audit shall be conducted by a public utility, an engineer or architect licensed by the state, or the managing agent or other representative of the company. A copy of the energy audit report, required herein, shall be given to any duly constituted tenant's association or cooperator's advisory council and a copy shall be available for inspection and copying by any individual tenant who requests it. The commissioner shall also require that every company certify by March thirty-first, nineteen hundred eighty-four that all compatible conservation measures identified in the energy audit report which have simple payback period of one year or less have been implemented; provided, however, if the commissioner determines within sixty days of the date the energy audit report is filed that one or more of such identified conservation measures cannot be implemented by March thirty-first, nineteen hundred eighty-four, given the projected rent revenues and any other monies available to the company from reserve funds, loans or grants from the state or federal government or any other source, the implementation of such conservation measures shall be provided for according to a schedule prescribed by the commissioner.
