British ventilation manufacturer Vent-Axia will showcase its latest ventilation systems for housebuilders and social housing providers at the first elementalLONDON exhibition, held at ExCeL London on 19-20 November 2025.
Visitors to stand D46 will be able to explore the company’s newest ventilation technologies, including the Lo-Carbon Sentinel Econiq range, and speak with Vent-Axia representatives about solutions for ventilation and overheating in residential developments.
The event is aimed at professionals in the built environment who are focused on reducing energy use and carbon emissions in large-scale residential and commercial projects.
Vent-Axia says it will demonstrate how its Lo-Carbon Sentinel Econiq range of Mechanical Ventilation with Heat Recovery (MVHR) supports net zero housing goals while addressing one of the sector’s growing challenges: overheating.
Addressing net zero and overheating in new homes
Steve Pearce, New Build Residential Product Manager at Vent-Axia, comments, “We are pleased to be part of the inaugural elementalLONDON exhibition and to engage with developers and specifiers focused on the future home standard.
“Visitors will be able to see our Lo-Carbon Sentinel Econiq range, which is designed for large-scale residential and social housing projects.
“Our team will also offer guidance on achieving compliance with Building Regulations and meeting net zero targets while improving indoor air quality.”
The Lo-Carbon Sentinel Econiq range is designed to provide energy-efficient ventilation, consistent thermal comfort, and compliance with Part O of the Building Regulations.
The line-up includes four models: the Lo-Carbon Sentinel Econiq, Passivhaus-certified units, the Sentinel Econiq Cool-Flow, and the Sentinel Econiq-Cool (KERS).
The Sentinel Econiq systems aim to mitigate overheating risks, which is a growing issue as new homes become more thermally efficient.
‘Approved Document O: Overheating’ of the Building Regulations sets out two key requirements: limiting unwanted solar gains and ensuring that excess heat can be effectively removed from the home. Ventilation plays a vital role in achieving both.
When additional cooling is required, the Sentinel Econiq Cool-Flow model integrates DX cooling for automatic active cooling, using intelligent controls that switch between heat recovery, summer bypass, and active cooling.
The Sentinel Econiq-Cool (KERS) unit combines an MVHR system with a KERS Coolboost air source heat pump. When passive cooling is insufficient, the system automatically activates mechanical cooling and renewable hot water production, providing a dual-function, energy-efficient approach.
Expanding the range to support housebuilders
Vent-Axia notes that housebuilders are increasingly adopting decentralised Mechanical Extract Ventilation (dMEV), alongside centralised MEV and MVHR, to reduce carbon emissions and meet the latest Building Regulations.
The Lo-Carbon NBR dMEV C has been developed specifically for the new-build residential sector, offering low Specific Fan Power (SFP) values of 0.08 W/l/s and near-silent operation, independently tested at 7.4 dB(A).
The unit is designed to reduce Dwelling Emission Rates (DERs) while improving energy efficiency and acoustic comfort.
