COMMISSIONING
Ensuring Every System Performs as Designed.
Building commissioning is one of the most critical — and most overlooked — steps in the delivery of a high-performance building. It is the process that bridges the gap between design intent and real-world performance, verifying that every system, assembly, and piece of equipment in a building is installed correctly, operating efficiently, and meeting the performance standards the owner expects and the project demands. At Breen Design Group, we provide rigorous, thorough commissioning services that give building owners confidence that their investment is performing exactly as it should.
Our commissioning process is systematic and comprehensive, encompassing careful planning, hands-on verification, detailed documentation, and clear reporting at every stage of the project. We provide commissioning services for new construction projects as well as retro-commissioning and re-commissioning services for existing buildings undergoing upgrades, renovations, or changes in occupancy — helping owners identify deficiencies, optimize system performance, and reduce long-term operating costs.
Breen Design Group serves as commissioning agent on projects across California and Washington State, working across a broad range of building types and mechanical, electrical, and plumbing systems. Our commissioning team works collaboratively with contractors, engineers, and building owners throughout the process, ensuring clear communication, thorough documentation, and fully verified system performance from initial startup through final acceptance.
The result is a building that works the way it was designed to work — from day one and for years to come. Explore our commissioning portfolio below.
