As successive UK Governments have rightly prioritised improving the energy efficiency of UK homes, important progress has been made in reducing heat loss and lowering carbon emissions. However, this progress has also brought an unintended consequence. 

Homes are becoming increasingly airtight, which can reduce natural ventilation and trap indoor pollutants when ventilation improvements are not implemented at the same time. 

This creates a clear challenge for policy. Energy efficiency and indoor environmental quality must be considered together, rather than in isolation, to ensure that homes are both low carbon and healthy to live in.

 

The role of ventilation in healthier homes 

BEAMA recognises that leadership in addressing this challenge must come from across industry, and that manufacturers and system providers have a key role to play in developing solutions that improve ventilation and indoor air quality. Where possible, industry should continue to innovate and deliver technologies that help mitigate indoor pollution and support healthier living environments. 

However, industry action alone is not enough. A supportive and consistent policy framework is required to ensure that improvements in energy efficiency are matched with equivalent progress in ventilation provision and indoor air quality standards. 

A policy framework for change 

Two years ago, BEAMA’s White Paper sets out a series of policy solutions designed to address this gap. These proposals reflect the expert insight of those responsible for delivering ventilation systems across the UK and are further supported by leading academics and key opinion leaders in the field. 

The aim is to ensure that policy development recognises the interconnected nature of energy efficiency, building performance, and occupant health, and creates the conditions for practical, scalable solutions.

Evidence and wider support 

This position is also supported by the 2018 White Paper from the All Party Parliamentary Group for Healthy Homes and Buildings, which highlights not only the importance of ventilation and indoor air quality, but also the broader relationship between housing conditions and the health and wellbeing of occupants. 

Taken together, this growing body of evidence reinforces the need for a more integrated approach to housing policy. One that ensures improvements in energy performance do not come at the expense of indoor environmental quality.
