We are excited to announce that Tate Walker, AIA, LEED Fellow, WELL AP,  has be promoted to Associate Principal, joining OPN’s leadership team.

In his more than two-decades as an architect, Tate has established himself as a nationally recognized leader on energy and sustainability in the built environment. Tate is an exemplary leader in our firm and industry, paving the way to a better earth through architecture.

He regularly writes and presents on issues relating to energy, technology, building science, and promoting environmental awareness through design. Tate has the distinctions of being named to the 2015 class of LEED Fellows and sitting on the AIA’s Committee on the Environment. Tate was a lead author of the COTE Toolkit, which assembles best practices, exemplary projects, metrics, and research to support the design of beautiful, high performing buildings. In 2019, AIA adopted the toolkit as the Framework for Design Excellence for the entire membership, to support a healthy, zero carbon, equitable, resilient future for all. He’s committed to pushing our practice to the forefront of sustainable design, delivering cost- and energy-efficient, health-conscious, and resourceful solutions to meet the varied needs of his clients.

I am inspired by the collaboration in my field of work and everyone that touches it. I’m always excited for a new project, and all the new ways I can serve a building and the people in it.

Tate also was the AIA Wisconsin President in 2019 and was part of the AIA COTE Leadership Group from 2017-2019. Tate has served many organizations, including cities and universities, holding positions on the USGBC Energy & Atmosphere Technical Advisory Group, a Chair on the AIA 2030 Commitment in 2021, the AIA Strategic Council from 2021-2022.

“Tate is a great leader across the firm and the architecture field. From projects to sustainability initiatives, he is extremely involved and dedicated to his work and those he works with. His experience is rooted in the architectural design process, but his knowledge spans far past programming and project management. Tate has been a crucial part in the development of technical guidelines for high performing buildings.” – Wes Reynolds, Principal
