Owner's Project Requirements

What Is It?

The Owner's Project Requirements (OPR) is a document prepared by the owner of a project to convey the functional requirements of a project and the expectations of the building's use and operation. If the program or mission elements change during the course of project delivery, the OPR should be updated to reflect changes in building performance requirements.

The OPR should address the following issues as applicable to the project:

• Owner and User Requirements: Describe the primary purpose, program, and use of the proposed project (e.g., office building with data center) and any pertinent project history. Provide any overarching goals relative to program needs, future expansion, flexibility, quality of materials, and construction and operational costs.
• Environmental and Sustainability Goals: Describe any specific environmental or sustainability goals (e.g., LEED Certification)
• Energy Efficiency Goals: Describe overall project energy efficiency goals relative to local energy code or ASHRAE Standard or LEED. Describe any goals or requirements for building siting, landscaping, façade, fenestration, envelope and roof features that will impact energy use.
• Indoor Environmental Quality Requirements: As applicable and appropriate, for each program / usage area describe the intended use; anticipated occupancy schedules; space environmental requirements (including lighting, space temperature, humidity, acoustical, air quality, ventilation and filtration criteria); desired user ability to adjust systems controls; desire for specific types of lighting; and accommodations for after-hours use.
• Equipment and System Expectations: As applicable and appropriate, describe the desired level of quality, reliability, type, automation, flexibility, and maintenance requirements for each of the systems to be commissioned. When known, provide specific efficiency targets, desired technologies, or preferred manufacturers for building systems.
• Building Occupant and O&M Personnel Requirements: Describe how the facility will be operated, and by whom. Describe the desired level of training and orientation required for the building occupants to understand and use the building systems.
