Why the UK must embrace decentralised ventilation systems
As the UK intensifies efforts to achieve its net zero carbon emissions target by 2050, the need for innovative solutions in building design has never been greater. One key area that deserves more attention is decentralised ventilation systems, a powerful yet often overlooked solution
Why decentralised ventilation?
In the UK, traditional centralised ventilation systems have long been the default choice for commercial and residential spaces. While effective in some environments, these systems often come with challenges:
• Complex ductwork: extensive duct networks can be invasive, expensive and disruptive to install, particularly in retrofit projects or heritage buildings.
• Energy inefficiency: long duct runs can lead to energy losses, reducing overall system efficiency.
• Maintenance challenges: centralised systems require regular inspection, cleaning and maintenance, often in hard-to-access areas.
In contrast, decentralised ventilation offers a fresh approach, with units placed directly within rooms or zones that require airflow. This simplified system removes the need for complex ducting networks and offers a host of benefits. Across much of Europe, decentralised ventilation has already gained significant traction. Many architects and engineers are far more open to adopting these systems thanks to their flexibility, performance benefits, and alignment with energy efficiency goals. The UK is now in a position to catch up and adopt this smarter, proven approach.
The key advantages of decentralised ventilation
Energy efficiency
Decentralised units are designed for targeted performance, reducing energy loss associated with long ducting systems. By delivering fresh air directly where it's needed, these systems enhance thermal efficiency — a crucial advantage in achieving lower carbon footprints.
Flexible installation
Decentralised systems are far easier to retrofit in older buildings, reducing disruption while improving indoor air quality. This is especially beneficial for the UK's many heritage properties, where preserving architectural integrity is vital.
Improved indoor air quality (IAQ)
By delivering filtered air directly into specific spaces, decentralised systems help maintain consistent air quality, reducing the risk of stale air build-up or contamination spreading through duct networks.
Lower maintenance requirements
Decentralised units require less maintenance since there are fewer components to manage. With easier access, routine servicing is simplified, reducing downtime and costs.
Enhanced comfort control
Since decentralised units are zoned, individual rooms can be controlled independently, giving occupants better temperature regulation and airflow control. This is particularly useful in multi-occupancy office buildings, schools, and healthcare facilities.
Unique one-façade design
MAPUK’s advanced decentralised solutions, (including the FVPpulse system) offer up to 90% heat recovery efficiency and require just one façade opening. This design allows fresh air to enter and stale air to exit through the same point, much like a building 'breathing' in and out through a single-entry point. This simplifies installation, reduces heat loss and maximises space efficiency.
Decentralised ventilation and sustainability
With sustainability dominating the UK’s construction agenda, decentralised systems play a crucial role in reducing energy consumption and supporting environmentally conscious design. Advanced decentralised solutions ensure that buildings retain warmth in colder months while optimising airflow. By integrating intelligent controls, these systems automatically adjust to demand, ensuring minimal energy waste. For projects aiming for BREEAM or WELL certification, decentralised systems support healthier indoor environments and operational energy savings.
A call for change
As the UK construction industry strives to meet net zero goals, decentralised ventilation systems provide an ideal solution for achieving improved energy efficiency and indoor air quality. It’s time for architects, interior designers and building consultants to be more open to exploring these innovative systems.
By embracing decentralised ventilation, we can create healthier, more sustainable spaces that align with the UK's environmental ambitions.
