Discover why physics-based metrics are essential for accurate HVAC feasibility studies and how they improve decarbonisation planning, financial analysis and system performance forecasts.
Many organisations are accelerating their decarbonisation plans, but the success of those plans depends on one essential question: Do we truly understand how the existing HVAC system behaves? Traditional feasibility studies often rely on assumptions, rules of thumb or static spreadsheets. While these can give a rough indication, they rarely reveal the real hydronic behaviour that determines whether low-carbon technologies will actually perform as expected.
This gap becomes a major risk when planning heat pump integration, low-temperature operation or system upgrades meant to cut emissions. Decarbonisation decisions made on guesswork often lead to oversizing, underperformance and unexpected cost increases.
Physics-based HVAC feasibility modelling removes this uncertainty by showing how the system will behave in reality, not just in theory.
Assumption-driven studies often fall short because they simplify what is, in reality, a dynamic and interconnected system. They typically overlook pressure losses, pump performance shifts, part-load behaviour or flow imbalances. These hidden factors can make or break a decarbonisation pathway, especially when transitioning to low-temperature heat sources.
A feasibility assessment built on estimates might suggest that a heat pump will perform adequately—only for the real system to fail to deliver the expected capacity. The consequences: higher costs, reduced comfort and delayed sustainability goals.
Physics-based HVAC feasibility modelling uses a digital twin to simulate real hydraulic and thermal behaviour under different operating conditions. Instead of depending on averages or fixed assumptions, it maps out:
This approach doesn’t just improve accuracy—it reduces risk. It ensures that the chosen decarbonisation pathway is viable before any investment is made.

Physics-based calculations allow consultants to test multiple decarbonisation strategies with confidence. Whether evaluating heat pump feasibility, hybrid configurations or low-temperature upgrades, each scenario becomes a measurable outcome rather than an educated guess.
Scenario results translate directly into business and sustainability metrics. Clients receive clear comparisons, showing which option delivers the best mix of comfort, efficiency, CO₂ reduction and cost-effectiveness.

Decarbonisation budgets are growing, and stakeholders expect reliable justification. The accuracy of physics-based feasibility modelling ensures that CAPEX decisions rest on verifiable system behaviour, not optimistic assumptions. As a result, consultants can provide confident recommendations backed by defensible data.
When clients understand not just what is possible, but why it works, alignment becomes easier—and investment moves forward faster.
