What are the Building Regulations requirements for ventilation?
Building Regulations set out the minimum requirements for ventilation in new and existing homes, helping to ensure adequate indoor air quality while supporting energy efficiency and building performance. For ventilation, Approved Document F (Ventilation) is the key guidance for England, alongside other relevant requirements including Approved Document L (Conservation of fuel and power) and Approved Document O (Overheating).
Titon provides practical guidance and resources to help architects, consultants, specifiers, developers and installers understand ventilation requirements and select appropriate ventilation solutions.
This includes guidance on trickle vents and background ventilation, mechanical extract ventilation (MEV), mechanical ventilation with heat recovery (MVHR), ventilation rates, airtightness, commissioning and compliance.
