   BASE BUILDING SYSTEMS. The systems and subsystems of a building that use or distribute energy and/or water and/or impact the energy and/or water consumption, including the building envelope; the heating ventilating and air conditioning (HVAC) systems; air conveying systems; electrical and lighting systems; domestic hot water systems; water distribution systems; plumbing fixtures and other water-using equipment; and landscape irrigation systems and water features. Base building systems shall not include:
   1.   Systems or subsystems owned by a tenant or for which a tenant bears full maintenance responsibility, that are within the tenant's leased space and exclusively serve such leased space, and for which the tenant pays all the energy and water bills according to usage and demand as measured by a meter or sub-meter.
   2.   Systems or subsystems owned by a residential unit owner that exclusively serve the residential unit of that owner.
   3.   Systems or subsystems that operate industrial applications such as manufacturing.
   BENCHMARKING REPORT. A report, generated by ENERGY STAR® Portfolio Manager, summarizing the annual energy and water performance of a building.
   DEPARTMENT. The City of Los Angeles Department of Building and Safety.
   ENERGY. Electricity, natural gas, steam, heating oil, or other products sold by a utility to a customer of a building, or renewable on-site electricity generation, for purposes of providing heat, cooling, lighting, water heating, or for powering or fueling other end-uses in the building and related facilities.
   ENERGY AUDIT. A systematic evaluation to identify potential modifications and improvements to a building's equipment and systems which utilize energy in order to optimize a building's overall energy performance.
   ENERGY STAR® PORTFOLIO MANAGER. The United States Environmental Protection Agency's (US EPA) online tool for measuring, tracking, and managing a building's energy, water and greenhouse gas emission data and to benchmark the performance of a building.
   ENERGY STAR® PORTFOLIO MANAGER ENERGY STAR SCORE. A number ranging from 1 to 100 assigned by the US EPA's Energy Star Portfolio Manager as a measurement of a building's energy efficiency, normalized for a building's characteristics, operations, and weather, according to methods established by US EPA's ENERGY STAR® Portfolio Manager.
   RETRO-COMMISSIONING. A systematic process for optimizing existing systems relating to building performance through the identification and correction of deficiencies in such systems.
   RETRO-COMMISSIONING MEASURES. Work relating to retro-commissioning such as repairs, maintenance, adjustments, changes to controls or related software, or operational improvements that optimize a building's energy and/or water performance.
   RETROFIT MEASURES. Upgrades or alterations of building systems involving the installation of energy and/or water efficiency technologies that reduce energy and/or water consumption and improve the efficiency of such systems.
   TREATMENT FACILITY. A facility where industrial processes take place for the treatment of substances, which include, but are not limited to, water, waste, sewage, rain water, oil, and chemicals. Paper mills, foundries, and similar operations are also covered by this definition, which is restricted to the building or buildings where the treatment takes place. (Added by Ord. No. 186,789, Eff. 11/12/20.)
   WATER AUDIT. A systematic evaluation to identify potential modifications and improvements to a building's equipment and systems which utilize water in order to optimize a building's overall water performance.
