1. Have been trained in a program meeting the curriculum requirements of paragraph (5)(c); and

2. Have demonstrated a proficiency in the areas listed in paragraph (5)(c) through a written test or practical demonstration.

(c) At a minimum, the curriculum to be followed in training auditors shall include instruction in the following areas:

1. The three types of heat transfer and the effects of temperature and humidity on heat transfer;

2. General mathematics, including powers of ten, decimals and fractions, simple equations, heat loss and heat gain computations utilizing British Thermal Units (BTUs), and pay back calculations;

3. Utility billing procedures, meter reading, and identification of weather sensitive consumption relationships based on a customer’s billing history;

4. Residential construction terminology and components;

5. The operation of heating and cooling systems used in residential buildings; and

6. The application of energy conservation practices and measures including the advantages and disadvantages of each.

(6) Pre-audit performance criteria for Computer-Assisted Audits.

(a) Every utility shall adopt procedures to assure that estimates of energy cost savings and costs for conservation measures are based on:

(8) Energy Audit Disclosures and Disclaimers.

(a) Each Computer-Assisted Audit result sheet shall include the following or similar statement: “The procedures used to make these installation cost and energy savings estimates are consistent with Commission rules and good engineering practices. However, the actual installation costs you incur and energy savings you realize from installing these measures may be different from the estimates contained in this audit report. Although the estimates are based on measurements of your house, they are also based on assumptions which may not be entirely correct for your household due to differing energy use patterns.”

(b) The auditor shall provide the eligible customer with a written statement of any interest, direct or indirect, which the auditor or the utility has in the sale or installation of any energy conservation measure.
