The Future Homes Standard, set to be implemented in 2025, mandates that new homes in England produce 75–80% fewer carbon emissions compared to those built under previous regulations. To achieve this, homes will be constructed with higher airtightness levels, necessitating more effective ventilation systems to maintain indoor air quality.
Approved Document F of the Building Regulations, which addresses ventilation, has been revised to support these goals. The updated regulations emphasize the need for continuous mechanical ventilation systems, such as dMEV and MVHR, to ensure adequate airflow in increasingly airtight homes.
Decentralised Mechanical Extract Ventilation (dMEV)
Decentralised Mechanical Extract Ventilation is designed to continuously extract stale, moist air from wet rooms such as kitchens and bathrooms. Operating quietly and efficiently, they help prevent condensation and mould while maintaining excellent indoor air quality.
- Quiet operation with ultra-low noise levels from 7.4dbA
- Low energy consumption for cost savings
- Smart humidity sensing for automatic control
- Easy to install and perfect for refurb or new build
- Compliant with current Building Regulations
- 7 year warranty
Recent updates to Building Regulations Part F (Ventilation) and Part L (Energy Efficiency) have made dMEV a preferred solution for meeting compliance. These changes highlight the importance of continuous mechanical ventilation to help improve indoor air quality in both new and existing homes.
Mechanical Ventilation with Heat Recovery (MVHR)
What is MVHR? MVHR systems provide whole-house ventilation by extracting stale air and supplying fresh, filtered air – while recovering heat from the outgoing air. Perfect for airtight homes, MVHR enhances indoor comfort while reducing energy bills
- Passivhaus certified
- New Sentinel-X wireless control platform
- Intelligent smart app control as standard
- Horizontal duct option for space-saving installations (M & L only)
- Sound levels as low as 15.5 dB(A) breakout – independently tested and verified by SRL
- Developed and manufactured in the UK
- Constant Volume – Maintains pre-set airflow irrespective of system pressure within it’s performance capabilities
- Built-in pre-heater as standard with optional external duct heaters
MVHR supports compliance with Building Regulations Parts F and L, helping meet ventilation and energy efficiency targets in new builds, particularly where airtightness is high.
