Dramatic CO₂ Reduction with Optimised AHU Systems
This infographic compares the environmental impact of two UK Air Handling Unit (AHU) systems, each delivering 1 m³/s of air. The standard AHU, using a Constant Air Volume (CAV) setup, emits 998 kg of CO₂ annually, with the supply and exhaust fans being the largest contributors. In contrast, the optimised AHU, equipped with intelligent Variable Air Volume (VAV) controls, reduces emissions to just 377 kg/year — a 60% reduction.
That’s a saving of over 600 kg of CO₂ per year, clearly demonstrating the environmental benefits of smart HVAC upgrades. From eliminating preheater emissions to significantly cutting fan energy use, this comparison makes a compelling case for intelligent control systems in sustainable building design.
