About ClimaWISE — Well Informed Smart Engineer

Engineered in the field. Perfected in the lab.

ClimaWISE didn't start in a boardroom. It was born on rooftops and in engine rooms where we saw the same problem over and over: Performance Drift. We took that real-world frustration and turned it into the world's most precise digital fingerprint for HVAC-R systems.

People first. Physics always. Evidence only.
Our origin

Born inside Delta Digital.

ClimaWISE was created through the collaborative vision of Erwin and Gabriël, who use Delta Digital as a launchpad for innovative digital solutions. To bridge the gap between technical theory and everyday practice.

We've paired high-level digital architecture with deep HVAC-R expertise to create a team that truly knows the physics behind the industry. Our philosophy is to first master and resolve the known variables through engineering logic; only then do we leverage AI to refine and optimize further. Together, we build the tools you need to master your energy performance and own your digital future.

Vision and methodology
Erwin ter Haar
Co-founder - The mind behind ClimaWISE
35years of hands-on HVAC-R experience

Erwin translated 35 years of hands-on HVAC-R experience and his background as a teacher in climate technology into the core engine of ClimaWISE. Having seen every way a system can fail, he realized the industry was not missing better sensors. It was missing the right context to understand what those sensors were saying. Erwin and the development team built the calculations and models that resolve the fundamental thermodynamics of a system. By first mastering these known physical laws, ClimaWISE establishes a foundation where AI is never used to guess the basics. Instead, it serves as a support tool to turn raw data into intelligence that is rooted in physics.

Scalable infrastructure
Gabriël de Jonge
Co-founder - Infrastructure & Security Lead

Gabriël facilitates the secure and scalable foundation of ClimaWISE. With his extensive experience in IT, he ensures the platform meets the highest standards for data integrity and network security. He provides the infrastructure that allows the complex physical models to run globally. Together with the Delta Digital team, he focuses on prioritizing cybersecurity and building a digital environment that is designed to grow without compromise.

Our vision

A world where no system wastes energy in silence.

We believe every HVAC-R system deserves to be understood, not just monitored. Performance drift is invisible until it is expensive. True progress starts with a platform that functions as the foundation for your company's collective knowledge. In an era where skilled personnel are scarce, we must capture the wealth of experience in the field before it is lost, securing it for the next generation.

At ClimaWISE, we believe that if you start with AI without a solid foundation, you will eventually miss the boat. The key to success is to first build solid structures and automate your core knowledge. Only then do you supplement with technology where it adds genuine value.

We use technology to bring back the simplicity the industry had 30 years ago. By translating complex thermodynamics into clear actions, we ensure that field experience is empowered, creating the Well Informed Smart Engineer which is the heart of ClimaWISE.

Not trends.

Movement without context. A temperature reading tells you nothing about the why.

Not alerts.

Thresholds react after the damage. False positives erode operator trust.

Physics.

We model the thermodynamic fingerprint of every system, turning raw data into diagnostic intelligence.

AI Support.

AI handles the complex calculations in the background so you can focus on what matters.

Definitions

The vocabulary behind ClimaWISE

Thermodynamic fingerprint
The unique performance signature of a specific HVAC-R system, built from weeks of continuous data across real operating conditions, used as the reference to detect drift.
Performance drift
The gradual, often invisible decline in HVAC-R efficiency caused by refrigerant loss, fouling, sensor error, or outdated setpoints. A system can look like it is "running" normally while it drifts.
Dynamic baseline
The expected performance of a system for its current operating conditions, continuously recalculated, rather than a single fixed setpoint from commissioning.
Expert co-pilot
The AI layer on top of the thermodynamic calculation engine that prioritises anomalies, explains their likely root cause, and estimates the energy or cost impact.
