12.2
Section 120.8(b). Owner’s or Owner representative’s Project Requirements (OPR). The energy-related expectations and requirements of the building shall be documented before the design phase of the project begins. This documentation shall include the following:
1. Energy efficiency goals;
2. Ventilation requirements;
3. Project program, including facility functions and hours of operation, and need for after hours operation; and
4. Equipment and systems expectations.
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 pre-design 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.
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. Energy Efficiency Goals – Establish goals and targets affecting energy efficiency which may include:
a. Overall energy efficiency (exceeding Title 24 by %)
b. Lighting system efficiency (exceeding Title 24 by %)
c. HVAC equipment efficiency & characteristics
d. Any other measures affecting energy efficiency desired by owner
1. Building orientation and sitting
2. Daylighting
3. Facade, envelope and fenestration
4. Roof
5. Natural ventilation
6. Onsite renewable power generation and net-zero energy use
7. Landscaping and shading
2. Ventilation Requirements - For each program space describe indoor ventilation requirements including intended use and anticipated schedule
3. Project Program, including facility functions and hours of operation, and need for after hours operation – Describe primary purpose, program and use of proposed project
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
4. 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
c. Degree of system integration, automation, and functionality for controls; i.e. load shedding, demand response, energy management
5. Enforcement
At their discretion, the building official confirms demonstrated compliance at Plan Review by:
a) Receipt of a copy of the OPR document (optional), and
b) Receipt of a form signed by the owner or owner representative attesting that the OPR has been completed and approved by the owner.
