Demand-Controlled Ventilation in London: How Smart Systems Cut Costs and Improve Air Quality

London’s commercial buildings face rising energy bills and stricter air quality regulations. Traditional ventilation systems run at full capacity regardless of occupancy, wasting energy and money. Demand-Controlled Ventilation (DCV) changes that by adjusting airflow in real time based on CO₂ levels and room usage—reducing energy consumption by 20–40% while maintaining healthy indoor air.
What is Demand-Controlled Ventilation and How Does It Work?
DCV Basics
DCV systems use sensors to detect occupancy and air quality (CO₂, VOCs, humidity). Airflow automatically increases when people enter a room or CO₂ levels rise, and decreases when spaces are empty or already well-ventilated. This responsive system delivers fresh air exactly where and when it’s needed, cutting unnecessary runtime.
Benefits of DCV for London Businesses
Energy Efficiency & Cost Savings
By avoiding constant fan operation, DCV systems can reduce ventilation energy costs by 20–40%, making them ideal for high-usage spaces such as offices, restaurants, and gyms. Lower energy demand also helps meet sustainability targets and reduce carbon emissions.
Improved Indoor Air Quality
Maintaining balanced CO₂ levels and reducing airborne contaminants improves staff well-being and customer comfort. Studies link good ventilation to higher productivity and fewer sick days in office environments.
Regulatory Compliance
DCV systems are a proven method to meet UK Building Regulations Part F, which specify minimum air change rates and indoor air quality requirements. With sensors and automated control, they ensure compliance with minimal manual intervention.
