Owners of buildings that used Appendix Z as a path for code compliance shall comply with this Section.
Owners of buildings that use Appendix Z as a path for code compliance shall annually benchmark and report their energy and water performance using the Energy Star® Portfolio Manager tool, including renewable energy generation and green power usage, pursuant to rules in 20 DCMR 3513, regardless of square footage.
Energy Star Portfolio Manager account. The owner of a building that used Appendix Z as a path for compliance with the Energy Conservation Code-Commercial Provisions shall create an Energy Star® Portfolio Manager account and property record on the U.S. Environmental Protection Agency's benchmarking website, and share the property with the District of Columbia's Department of Energy and Environment. The code official is authorized to require proof of compliance with this Section Z5.3.1 and proof that all utilities have been linked to the account.
Performance Verification. Within 24 months of occupancy, the owner or owner's representative shall submit documentation to the code official demonstrating 12 continuous months of operation with no less than 90% occupancy where the energy consumed by the building and building site as measured in accordance with Section Z4 are equal to or less than the renewable energy associated with the building and building site in accordance with Section Z3. Documentation shall be in a form acceptable to the code official.
Normalization for abnormal conditions. At the discretion of the code official, the owner or owner's representative may submit documentation demonstrating that abnormal weather or occupancy conditions during the compliance period are responsible for the variance between the energy consumed by the energy and energy site and the renewable energy associated with the building and building site and that the building would comply with Z5.2 under normal conditions.
