DESIGNED BY ENGINEERS. PROVEN BY DATA. DRIVEN BY EFFICIENCY.
At Wirth HQ, our engineers apply advanced CFD and thermodynamic modelling to help clients achieve measurable, double-digit reductions in building energy use – while optimising thermal comfort, indoor air quality, and system performance.
Now, that capability has evolved into an energy revolution.
Meet ClimateFlow – the intelligent heating/cooling layer that helps buildings capture, re‑use, and optimise energy that would otherwise be lost. Instead of treating heating and cooling as one‑way processes, ClimateFlow joins up your existing HVAC and refrigeration assets into a live system that keeps useful energy in circulation for longer.
Rather than replacing your current design work, ClimateFlow builds on it. Your plant and control strategies stay in place; ClimateFlow simply adds an additional lever by exposing where heat is being rejected, where cooling is being over‑delivered, and how those flows can be rebalanced across zones.
“Our simulations showed something extraordinary: the cleanest way to heat and cool a store is to stop thinking like an HVAC engineer and start thinking like a Formula One aerodynamicist.”
Nick Wirth
Developed through deep simulation and refined with customers in real sites, ClimateFlow is designed to support your engineering team, not compete with it. You have already pushed conventional approaches a long way; ClimateFlow adds a data‑driven way to capture and redeploy thermal energy that standard control sequences typically cannot see.
In pilot environments, this integrated approach to airflow control and heat recovery has enabled customers to achieve significant reductions in both total energy demand and gas usage, while maintaining comfort and compliance.
“By installing the ClimateFlow system in store, we have drastically cut our energy bills and significantly reduced our emissions. We hope that this novel energy-recycling solution provides a blueprint for efficiency and sustainability across the entire retail sector.
At BWG, we wanted to prove that profitability and sustainability can, and should, support one another.”
Barry Carty, head of retail development at BWG Foods
The biggest gains tend to come where there is substantial waste heat to reclaim and where ClimateFlow can orchestrate how that energy is re‑used across the store.
ClimateFlow helps you move from static setpoints to a learning system that treats every watt as an asset: capturing it when it appears, re‑using it where it adds value, and continuously optimising how the building responds over time.
Keep the energy working. Keep the comfort high. Keep costs under control.
