NAC704.820. Proposed methodology for performing inspections.

     1. Each utility shall develop a proposed methodology for performing its residential inspections and shall submit its proposed methodology to the Commission for approval.

     2. Except as otherwise provided in NAC 704.822, the proposed methodology must require that:

     (a) The inspector’s calculations be based upon data collected by him or her from actual measurements of the interior and exterior of the building and inspection of the equipment used for heating and cooling spaces and heating water.

     (b) The data collected be in sufficient detail to enable the inspector to provide the customer with the following information:

          (1) A reasonably accurate estimate of the total cost, including materials and labor, to have an installer install the appropriate material and equipment for each applicable measure for conserving energy.

          (2) A reasonably accurate estimate of the total cost for the eligible customer to purchase and install the appropriate material and equipment for each of those measures, including replacing a central air conditioner, installing wall insulation, or replacing or modifying a furnace, boiler or heat pump.

          (3) A reasonably accurate estimate of the total savings in energy, expressed in dollars and kilowatt hours of electric energy or cubic feet of gas, which would be likely to occur during the first year following completion of each appropriate measure.

          (4) An estimate of the savings, after taking into consideration any available federal tax credits, in cost of energy, expressed in dollars, which would be likely to occur during the first year following completion of all applicable measures, assuming that those measures are carried out in the order of the shortest simple pay back, which is calculated by dividing the estimated cost of installation by the estimated saving from the measure in the first year.
