  The Owner’s Project Requirements (OPR) documents the functional requirements of a project and expectations of the building use and operation as it relates to systems being commissioned. The document describes the physical and functional building characteristics desired by the owner and establishes performance and acceptance criteria. The OPR is most effective when developed during predesign and used to develop the Basis of Design (BOD) during the design process. The level of detail and complexity of the OPR will vary according to building use, type and systems.

  1.2 Compliance Method:

  Compliance is demonstrated by the owner or owner’s representative developing and/or approving the Owner’s Project Requirements (OPR) document and can be defined as follows:

  1. Environmental and Sustainability Goals—Establish environmental project goals and objectives exceeding the code for the project’s sustainability, which may include: a. CALGreen voluntary measures or Tiers sought, or other specific green building rating system or program credits and/or level of certification sought b.

  2. Building Sustainable Goals—Establish goals and targets affecting energy efficiency, which may include: a. Measures affecting building sustainability desired by owner i. Building orientation and siting ii. Daylighting iii. Facade, envelope and fenestration

  iv. Roof

  v. Natural ventilation

  vi. Onsite renewable power generation and net-zero energy use vii. Landscaping and shading 3. Indoor Environmental Quality Requirements—For each program space describe indoor environmental requirements including intended use and anticipated schedule, and the following: a. Temperature and humidity

  b. Acoustics

  c. Air quality, ventilation and filtration d. Desired adjustability of system controls

  e. Accommodations for after-hours use

  f. Other owner requirements including natural ventilation, operable windows, daylight, views, etc. 4. Project Program, including facility functions and hours of operation, and need for after-hours operation—Describe primary purpose, program and use of proposed project include the following: a. Building size, number of stories, construction type, occupancy type and number b. Building program areas including intended use and anticipated occupancy schedules c. Future expandability and flexibility of spaces d. Quality and/or durability of materials and building lifespan desired e. Budget or operational constraints f. Applicable codes 5. Equipment and Systems Expectations—Describe the following for each system commissioned: a. Level of quality, reliability, equipment type, automation, flexibility, maintenance and complexity desired b. Specific efficiency targets, desired technologies or preferred manufacturers for building systems, acoustics and vibration c. Degree of system integration, automation and functionality for controls 6.

The software tools and data sets shall be the same for evaluation of both the baseline building and the proposed building.

  Exception: For projects that include building reuse, the reference baseline building shall exclude the reused elements. The percent reduction in GWP shall be achieved through the design and construction of new project elements.

  A5.409.2.2 Tier 2. Projects shall conduct a cradle-to-grave whole building life cycle assessment meeting the requirements of Section 5.409.2 and performed in accordance with ISO 14040 and ISO 14044, excluding operating energy, demonstrating a minimum 20-percent reduction in GWP as compared to a reference baseline building of similar size, function, complexity, type of construction, material specification, and location that meets the requirements of all parts of the California Building Standards Code currently in effect. Software used to conduct the whole building life cycle assessment, including reference baseline building, shall have a data set compliant with ISO 14044, and ISO 21930 or EN 15804, and the software shall conform to ISO 21931 and/or EN 15978. The software tools and data sets shall be the same for evaluation of both the baseline building and the proposed building.

  Exception: For projects that include building reuse, the reference baseline building shall not be of new construction and shall retain existing materials. The percent reduction in GWP shall be achieved through the design and construction of new project elements.

  A5.409.2.3 Verification of compliance. A summary of the GWP analysis produced by the software and Worksheet WS-7 signed by the design professional of record shall be provided in the construction documents as documentation of compliance. A copy of the whole building life cycle assessment which includes the GWP analysis produced by the software, in addition to maintenance and training information, shall be included in the operation and maintenance manual and shall be provided to the owner at the close of construction. The enforcing agency may require inspection and inspection reports in accordance with Sections 702.2 and 703.1 during and at completion of construction to demonstrate substantial conformance. Inspection shall be performed by the design professional of record or third party acceptable to the enforcing agency.

  A5.409.3 Product GWP compliance—prescriptive path. Each product that is permanently installed and listed in Table A5.409.3 shall have a Type III environmental product declaration (EPD), either product-specific or factory-specific.

  SECTION A4.201—GENERAL

  A4.201.1 Scope. For the purposes of mandatory energy efficiency standards in the California Building Standards Code (Title 24), the California Energy Commission will continue to adopt mandatory standards in the California Energy Code (Title 24, Part 6). It is the intent of these voluntary provisions to encourage local jurisdictions through codification to achieve exemplary performance in the area of building energy efficiency. Local jurisdictions adopting these voluntary provisions as mandatory local energy efficiency standards shall submit the required application and receive the required approval of the California Energy Commission in compliance with Title 24, Part 1, Section 10-106 prior to enforcement. Once the required filing has been verified and finding has been made by the Energy Commission, local jurisdictions shall file an ordinance expressly marking the local modification along with findings and receive the required acceptance from the California Building Standards Commission in compliance with Section 101.7 of this code, prior to enforcement. (Title 24, Part 1, Section 10-106 is available at https://www.energy.ca.gov/programs-and-topics/programs/build- ing-energy-efficiency-standards/2025-building-energy-efficiency

  SECTION A4.203—PERFORMANCE APPROACH FOR NEWLY CONSTRUCTED BUILDINGS

  A4.203.1 Energy efficiency. Newly constructed low-rise residential buildings shall comply with Sections A4.203.1.1 through A4.203.1.4.

  A4.203.1.1 Long-term system cost (LSC). LSC rating for the building’s Proposed Design shall be computed by Compliance Software certified by the Energy Commission as specified in Title 24, Part 6, Section 100.1 and 150.1(b), and shall reduce the LSC required in the Compliance Software for minimum performance-based compliance with the California Energy Code by the compliance margin specified in Table A4.203.1.1. The rating shall be included in the Certificate of Compliance documentation.
