Tetra Tech’s High Performance Buildings Group provided energy modeling and advanced analytics to decarbonize the California State University (CSU) system’s existing utility infrastructure.

Tetra Tech developed a system-wide decarbonization framework for CSU to reduce the greenhouse gas (GHG) emissions of fossil fuel-based systems. This framework will support the decarbonization and climate action efforts across all 23 CSU campuses.

With Tetra Tech’s support, the CSU system can realize a 70 percent reduction potential in natural gas consumption, meet their climate action commitments, and support California’s goal to be carbon neutral by 2025. Campuses were prioritized for carbon-free heating systems using submeter data, inverse energy modeling, and predictive analytics.

We used Tetra Tech Delta technologies to deliver an innovative solution for our client.

Tetra Tech building energy modelers developed a central utility plant scenario analysis planning tool and dynamic dashboards that allow each CSU campus to make decisions regarding how to optimize heat recovery strategies and create a unique plan to reduce GHG emissions. These dashboards enable stakeholders to better understand the multidimensional impacts of a carbon-free heating system and can be used to develop a long-term clean energy strategy. Tetra Tech also developed a system-wide decarbonization framework that consisted of policy reviews, mechanical design and energy modeling guidelines, technology assessments, and decarbonization strategies.

Tetra Tech worked closely with a CSU energy managers task force and the CSU Chancellor’s Office to to develop a broad decarbonization framework that applies to and is approved for use across the unique infrastructure and operation conditions of the CSU’s 23 campuses.

Climate Change Business Journal recognized Tetra Tech with a Project Merit Award for supporting CSU's decarbonization and climate action efforts across all 23 campuses.
