Syntraal Makes Sustainability Decisions More Insightful with Hysopt

At Dutch consultancy Syntraal, a large share of projects focuses on decarbonising existing buildings and developing fifth-generation district heating networks. In each case, the same question lies at the heart of the work: which choices will deliver the best long-term outcome?

Traditionally, these decisions were based on experience, Excel calculations, and engineering rules of thumb. According to Geert van Rens, Energy Transition Consultant at Syntraal, this approach often worked well, but making adjustments was time-consuming and comparing different scenarios in depth remained difficult.

‍

With Hysopt, Syntraal has found a way to analyse those choices faster, more interactively, and with greater confidence. Instead of developing a single solution, engineers can compare multiple concepts side by side and clearly visualise the impact of design decisions.

Another key benefit of Hysopt is the ability to validate existing hydraulic designs and identify design flaws. This is particularly valuable when there are indications that a system is not performing as intended, when components are wearing out faster than expected, or when there is a suspicion that a design error may have been made.

‍

In these situations, Hysopt provides the ability to detect issues and evaluate optimisation opportunities before changes are implemented.

‍

The objective is not only to identify faults, but also to ensure that existing and newly added systems work together as intended. This is particularly important in renovation and decarbonisation projects, where integrating old and new technologies often presents significant challenges.

‍

For Syntraal, this combination of analysis and validation delivers substantial value. It provides greater confidence that a proposed solution will perform as expected in practice.

While Hysopt streamlines Syntraal’s internal engineering process, the consultancy also sees significant value for its clients.

‍

According to the team, a project without Hysopt often results in a more traditional advisory approach. With Hysopt, the impact of different design choices can be demonstrated and substantiated much more clearly.

‍

Visualisations, simulations, and side-by-side comparisons make it easier to explain why one concept performs better than another. This helps clients make investment decisions with greater confidence.

‍

Syntraal also sees opportunities further along the design process. The models not only provide insights during the advisory phase, but can also serve as a foundation for subsequent stages, including preliminary design and implementation. As a result, a single, consistent source of information can increasingly be carried through multiple project phases.

‍

For a consultancy that works on decarbonisation challenges every day, success ultimately depends on more than calculations alone. It is about supporting better decisions. And that is precisely where Syntraal sees the greatest value in Hysopt.
