PassiHVAC is a specialist company delivering passive ventilation solutions, building performance analysis, and low-carbon design support for the UK built environment. We support developers, local authorities, architects, and engineers in achieving regulatory compliance, thermal comfort, indoor air quality, and operational energy reduction.

 

Our work integrates passive ventilation systems, CFD-based environmental modelling, and evidence-led sustainability assessment to address overheating risk, air quality, and climate resilience across new-build and retrofit projects.

 

PassiHVAC operates at the interface of research, engineering practice, and policy, enabling design teams to move beyond prescriptive compliance and towards measurable performance outcomes.
