Collecting and entering benchmarking data.
Ann Arbor City Code § 8:453
in effect8:453. - Collecting and entering benchmarking data.
(1) Each year the owner of each covered property shall collect and enter all data needed to benchmark the entire property for the previous calendar year into the benchmarking tool in a manner that conforms to the latest guidance provided by the U.S. Environmental Protection Agency for use of the benchmarking tool. Aggregated whole-building data for the property's energy and water use shall be compiled using one or more of the following methods:
(a) Obtaining aggregated whole-building data from a utility; or
(b) Collecting data from all tenants; or
(c) Reading a master meter.
(2) If the owner of a covered property does not have access to aggregated whole-building energy and water data, such owner shall request aggregated whole-building data from each utility that provides energy of water service to the property. When a utility does not provide aggregated whole-building energy or water data, the owner of a covered property shall request tenant energy and water data using a form provided by the city. Owners may also request authorization from tenants for the utility to share their data in an aggregated format with the owner.
(3) Each nonresidential tenant located in a covered property shall, within 30 days of a request by the owner, provide all information that cannot otherwise be acquired by the owner and that is needed by the owner to comply with the requirements of this ordinance.
(4) Nothing in this chapter shall be construed to permit an owner to disclose or use tenant energy usage data for any purpose except compliance with the requirements of this chapter, nor shall the reporting requirements of this chapter be construed to excuse owners from compliance with federal or state laws governing direct access to tenant utility data from the responsible utility.
(5) If the tenant of a covered property fails to provide information to the owner as provided in this section, the owner shall be considered in compliance with the reporting requirements of this chapter with respect to the building if (1) the owner proves that the owner has requested the tenant to provide such information as specified in this section in a format as required by the manager; and (2) the owner has used the benchmarking tool for the building using all information otherwise available to the owner. The Manager may provide alternate values as established by the Department.
