CIAT has reinforced its call for the UK government to prioritise indoor air quality (IAQ) in forthcoming legislation, citing findings from a recent Building Engineering Services Association (BESA) event.
With growing evidence linking poor IAQ to significant health, economic and environmental consequences, CIAT advocates the urgent need for enforceable standards to safeguard public health and improve building performance.
Matt Maleki, Business Development Manager and IAQ Specialist at CIAT, said: “The recent political change offers a rare opportunity to revise building regulations and the findings from the BESA event make it clear: we have a short window to act. Legislation must enforce mandatory IAQ standards to protect occupants and ensure healthier, more efficient buildings. Healthy buildings are efficient buildings, and with 80% of current buildings expected to be still in use by 2050, it’s undeniable that the time to act is now.”
CIAT highlights the need for a unified approach to IAQ, addressing both new and existing buildings. Without clear legislative guidance, many developers are unsure of the best solutions, slowing progress toward healthier environments. Comprehensive regulations would establish enforceable IAQ thresholds, such as limits on CO2 and PM levels, ensuring ventilation systems operate effectively based on occupancy and building type.
Advanced technologies, including demand-controlled ventilation and air quality sensors, can significantly enhance IAQ while optimising energy efficiency. For example, clean filters ensure proper airflow and that motor consumption does not exceed design in order to remain efficient, maintain energy costs and prolong system life. Legislation that supports these measures will provide clarity and encourage widespread adoption of best practices.
CIAT supports calls, such as BEAMA’s EPC Reform Position Paper which was launched at the BESA event, to reform Energy Performance Certificates (EPCs) to include health-focused IAQ metrics. With 442,000 EPCs lodged on the Energy Performance of Buildings Register (England and Wales) from July to September 2024 alone, such reforms could drive improvements in a significant number of homes annually, incentivising property owners and developers to adopt sustainable practices. A dedicated IAQ certification could further complement these efforts, providing a clear framework to assess and enhance air quality in all buildings.
The government’s Warm Homes Plan, aimed at lifting a million households out of fuel poverty, must also incorporate IAQ considerations, says the manufacturer. Systems designed to improve air quality can reduce operational costs, demonstrating that energy efficiency and occupant health go hand in hand. Countries like Sweden, France, and Ireland lead the way with independent frameworks for ventilation oversight, ensuring high standards through regular inspections. The UK risks falling behind without adopting similar measures. “Getting IAQ right locally not only benefits public health but also sets global benchmarks for sustainable building practices in homes, commercial properties and public buildings,” added Maleki.
“The solutions exist, but without government action, progress will remain limited. We need legislation that reflects the urgency of this issue to ensure that today’s buildings – and those of the future – are healthier, more efficient, and fit for purpose in 2050 and beyond.”
