(1) On and after January 1, 2010, qualifying utilities shall maintain records of the energy consumption data of all nonresidential and qualifying public agency buildings to which they provide service. This data must be maintained for at least the most recent twelve months in a format compatible for uploading to the United States environmental protection agency’s energy star portfolio manager.

(2) On and after January 1, 2010, upon the written authorization or secure electronic authorization of a nonresidential building owner or operator, a qualifying utility shall upload the energy consumption data for the accounts specified by the owner or operator for a building to the United States environmental protection agency’s energy star portfolio manager in a form that does not disclose personally identifying information.

(3) In carrying out the requirements of this section, a qualifying utility shall use any method for providing the specified data in order to maximize efficiency and minimize overall program cost. Qualifying utilities are encouraged to consult with the United States environmental protection agency and their customers in developing reasonable reporting options.

(4) Disclosure of nonpublic nonresidential benchmarking data and ratings required under subsection (5) of this section will be phased in as follows:

(a) By January 1, 2011, for buildings greater than fifty thousand square feet; and

(b) By January 1, 2012, for buildings greater than ten thousand square feet.

A building owner or operator, or their agent, who delivers United States environmental protection agency’s energy star portfolio manager benchmarking data and ratings to a prospective buyer, lessee, or lender is not required to provide additional information regarding energy consumption, and the information is deemed to be adequate to inform the prospective buyer, lessee, or lender regarding the United States environmental protection agency’s energy star portfolio manager benchmarking data and ratings for the most recent twelve-month period for the building that is being sold, leased, financed, or refinanced.

(6) Notwithstanding subsections (4) and (5) of this section, nothing in this section increases or decreases the duties, if any, of a building owner, operator, or their agent under this chapter or alters the duty of a seller, agent, or broker to disclose the existence of a material fact affecting the real property.

(7) An electric or gas utility that is not a qualifying utility must either offer the upload service specified in subsection (2) of this section or provide customers who are building owners of covered commercial buildings with consumption data in an electronic document formatted for direct upload to the United States environmental protection agency’s energy star portfolio manager. Within sixty days of receiving a written or electronic request and authorization of a building owner, the utility must provide the building owner with monthly energy consumption data as required to benchmark the specified building.

(8) For any covered commercial building with three or more tenants, an electric or gas utility must, upon request of the building owner, provide the building owner with aggregated monthly energy consumption data without requiring prior consent from tenants.

(9) Each electric or gas utility must ensure that all data provided in compliance with this section does not contain personally identifiable information or customer-specific billing information about tenants of a covered commercial building.
