Energy Efficiency Audits and Energy Efficiency Audit Reports. The owner of any nonresidential building with a gross area of 10,000 square feet or greater shall conduct a comprehensive energy efficiency audit for each such building. Energy efficiency audits shall comprehensively examine whole buildings, and must be completed on the schedule set forth in Section 2004 of this Chapter, or as described in Section 2006, as applicable.
Energy Efficiency Audit Standards. Energy efficiency audits required by this Chapter shall meet or exceed the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) Procedures for Commercial Building Energy Audits (2004), or shall comply with Section 2006, as applicable. Energy efficiency audits must be performed by, or under the supervision of, an energy professional as defined in subsections (c) and (d), below. The level of detail required in an energy efficiency audit shall be proportionate to the scale of the nonresidential building, such that:
Buildings greater than 50,000 square feet in gross area shall receive a comprehensive audit of the whole building which meets or exceeds the Level II Audit standard or equivalent as determined by the Director.
Buildings greater than 10,000 square feet and less than or equal to 49,999 square feet in gross area receive a walkthrough audit of the whole building which meets or exceeds the Level I audit standard, or equivalent as determined by the Director.
Energy Efficiency Auditor Qualifications. An energy professional performing or supervising energy efficiency audits must be able to demonstrate possession in good standing of at least one of the following minimum qualifications:
Licensed Engineer and one of the following:
At least 2 years experience performing energy efficiency audits or commissioning of existing buildings; or
ASHRAE Commissioning Process Management Professional Certification; or
Similar qualifications in energy efficiency analysis or commissioning.
Association of Energy Engineers Certified Energy Manager (CEM), and at least 2 years experience performing energy efficiency audits or commissioning of existing buildings;
At least 10 years experience as a building operating engineer, or at least 5 years experience as a chief operating engineer and one of the following:
BOC International Building Operator Certification; or
International Union of Operating Engineers Certified Energy Specialist; or
Equivalent professional qualifications to manage, maintain, or evaluate building systems, as well as specialized training in energy efficiency audits and maintenance of building systems, as determined by the Director.
Energy Efficiency Audit Report. The energy professional shall prepare, sign, and deliver to the owner of the covered building a report of the energy efficiency audit which meets or exceeds the reporting standards set forth in ASHRAE Procedures for Commercial Building Energy Audits (2004 or later), or equivalent as determined by the Director pursuant to this Section or Section 2006, as applicable. The signed report shall be delivered to the owner of the covered building. In the course of meeting the relevant ASHRAE standards for communication, the energy efficiency audit report shall include:
The date(s) that the audit was performed;
A list of all retro-commissioning and retrofit measures available to the owner;
An estimate of the approximate energy savings, avoided energy cost, and costs to implement each measure; and
One of the following:
A list of all retro-commissioning and retrofit measures available to the owner with a simple payback of not more than 5 years; or
A list of all retro-commissioning and retrofit measures available to the owner with a positive net present value; or
An integrated package of retro-commissioning and retrofit measures that in combination will equal or exceed the total combined reduction in energy consumption of implementing all retrofit and retro-commissioning measures with a simple payback of not more than 5 years.
Tracking and benchmarking energy performance. Building owners shall use “EPA ENERGY STAR® Portfolio Manager” to track the total energy use of each non-residential building and obtain an ENERGY STAR® Portfolio Manager Energy Performance Rating for each applicable entire nonresidential building according to the schedule provided in Section 2004.
