Brummitt Energy Associates Joins Stok

San Francisco (November 18, 2019) – We’re thrilled to announce today that after a decade of collaboration, San Diego-based building performance consultant Brummitt Energy Associates has joined Stok. This partnership immensely deepens Stok’s engineering capabilities and establishes Stok’s first Southern California office, which will now benefit from expanded sustainable real estate service offerings, a greater depth of resources, and wider geographic reach.

“After working together with Stok over the past decade, we’re excited for the opportunities to create a more environmentally restorative future together! The decision was driven by our desire to provide clients the benefit of a larger platform and a far more comprehensive suite of high-performance real estate services.”
-Beth Brummitt, Founder and Principal, Brummitt Energy


Stok’s clients will benefit from strengthened in-house engineering expertise spanning whole-building energy modeling and analysis, lighting and daylighting, measurement and verification (M&V), and monitoring-based commissioning (MBCx) to achieve optimal building performance. Recognized as an industry leader in Zero Net Energy (ZNE) buildings, the Brummitt Energy team has delivered over 190 LEED certified projects across six countries and has over 30 ZNE projects in design, construction, or verified. As Stok, this deep experience will provide clients with even greater ability to achieve cost-effective, energy-efficient solutions that deliver accretive financial returns while meeting their Zero Carbon goals.

“Integrating with this renowned group of Zero Energy experts strengthens our capability to deliver the highest performing real estate to our clients. As the market continues to push toward Zero Carbon buildings, together we’re exceedingly better equipped to provide innovative solutions for greater positive impact with deeper energy engineering expertise across a wider variety of real estate product types.”
-Matt Macko, Founder, Stok

Brummitt Energy’s portfolio of work further expands Stok’s geographic reach and project type expertise. Founded in San Diego in 1998, the Brummitt Energy team’s strong, long-standing Southern California presence is captured in a robust collection of projects ranging from commercial, to education, government, and civic portfolios, including Sempra Energy’s HQ, Santa Monica College’s Core Performance Center, the Alpine Branch Library, and San Diego County’s Zero Net Energy Portfolio Plan.

Likewise, Brummitt Energy clients will gain access to significantly expanded high-performance real estate services, including construction management, commissioning, and sustainable building consulting and certification management (including LEED, Living Building Challenge, WELL Building Standard, GreenPoint Rated, GRESB, GRI, and CASBEE, among others).

Integrating with Stok’s team across offices in San Francisco, Denver, and now San Diego, as well as on projects locally and across global portfolios, Brummitt Energy clients will also benefit from the extensive resources and geographic reach of an organization that has been one of San Francisco’s 100 fastest-growing companies for six of the past seven years.

Beyond these tangible benefits, clients will also get to experience our combined forces as one cohesive team. As partners over the past decade, Stok and Brummitt Energy have collaborated on over two dozen high-performance projects, including two of California’s largest ZNE buildings (the Zero Net Energy Center in San Leandro and the Net Zero Plus Electrical Training Institute in Los Angeles). Combined, our teams have delivered over 55 ZNE buildings for our innovative clients. As one integrated team, we’re excited to see what we can accomplish together!


Effective November 16, 2019, Brummitt Energy is Stok, establishing Stok’s first Southern California office in sunny San Diego. The rest of Stok’s construction management, engineering, and sustainable building consulting experts remain in Stok’s San Francisco and Denver offices.
