Approach
How we work.
Jouler's work today is direct engagement with early thermal energy network deployments. We focus on the data side of a TEN, from initial feasibility through operations, doing the work that turns each system into evidence the next project can build on.
Core work
Project partnerships
We work alongside utilities, municipalities, campuses, and developers navigating their first thermal energy networks, taking on the analytical and data work that often falls through the cracks of a traditional engineering-led process.
Feasibility and screening.
Before a project goes into detailed engineering, we assess whether a TEN makes sense for the site across technical, economic, and institutional dimensions. This work draws on physics-based modeling and a consistent analytical approach, so each project sharpens the screening for the next one.
Owner's data representative.
On a typical project, the data and instrumentation decisions default to whoever installs the controls, and they get treated as implementation details rather than design choices. We sit on the owner's side of the table, defining what the system needs to measure and how that data should be structured, then staying involved through design and commissioning so those decisions actually get built rather than deferred.
Operational analysis.
Once a system is running, we do the work the sector doesn't yet have good benchmarks for: reading performance trends, diagnosing efficiency gaps, validating the economics, and understanding grid interactions. Where the operational record is thin, we fill in gaps with engineering simulation to produce analyses that hold up to scrutiny.
Broader contribution
Applied research
Alongside project work, we contribute to the shared technical foundations of the TEN sector: improving open-source modeling tools, refining analytical approaches, and publishing methodologies that others can build on. The goal is a technical commons the whole industry benefits from, not a set of tools only we can use.
Why us
Why work with us
01
Depth in a narrow field.
TENs are a specialty, and we've been focused on them since before they were a recognized category. That background informs the analytical approach and means we're not learning on the job at a client's expense.
02
Data considered from the start.
Instrumentation and data questions tend to surface late in a project, once much of the infrastructure is already specified. We bring them in at the feasibility stage, when the answers can still shape what gets built.
03
Aligned incentives.
Our long-term business depends on more TENs being built. Every engagement is structured to help that happen, not to sell a product you don't need.
Let's talk.
Whether you're in the early stages of evaluating a thermal network, somewhere in the middle of one, or looking for a second opinion on an existing project, we're happy to have a conversation.
