Building Performance Analyst I

Is building science your jam? Do you consistently think of ways to push the building performance envelope and help make our planet more sustainable by promoting healthy, comfortable spaces that leave a smaller carbon footprint in the community? If so, we’re looking for you!

O’Brien360’s Building Performance (BP) team is seeking a building analyst whiz with a passion for efficiency and the right mix of technical and people skills that enable them to be equally at ease with a designer, contractor, or building owner.

Our BP team is dedicated to supporting the long-term performance, sustainability, and livability of existing buildings. We understand that the need for efficiency and sustainability doesn’t end once the ribbon is cut and that building performance is an essential factor in a project’s life cycle. Working alongside architects, owners, and mechanical engineers, we will help identify valuable opportunities for increased building performance.

We’re known for coupling technical rigor and clear communication to help clients meet and exceed their goals. Our specialized knowledge of modeling tools, advanced green building rating systems, and innovative technologies allows us to offer clients a high level of technical assistance and analysis with their building performance goals. Areas of focus include energy efficiency, thermal comfort, indoor air quality, water efficiency, and daylighting.

To support the O’Brien360 Vision and Mission, the BP team provides services to many affordable housing providers in the Puget Sound area and some providers in other regions of the state; 70% of our current workload on the BP team is related to affordable housing.
