Air Quality and Health in Social Housing
On average, people spend the vast majority of their lives indoors—around 55 years in their own homes. Vulnerable groups such as the elderly or young children spend even more time inside, making them particularly susceptible to the effects of poor indoor air quality. Poor air quality not only impacts health directly but also has knock-on effects on the NHS, increasing the burden of respiratory issues, allergies, and other related conditions. The healthcare cost of treating conditions linked to poor indoor air quality, such as asthma, is significant and highlights the need for better air quality management in social housing. This makes indoor air quality not just a comfort issue but a significant health concern, especially for those living in social housing.
We’ve installed countless ventilation measures for social housing providers. If you’d like to talk to us about improving ventilation in your property, please contact us for a free ventilation review.
Indoor Air Quality Concerns
The air inside our homes is more than just oxygen and carbon dioxide. It’s a mix that also contains harmful pollutants. Ethanol, which is commonly found in everyday items like makeup, paint, and varnish, can make up as much as a third of indoor pollution. Other harmful pollutants include particulate matter (PM), formaldehyde, and various other chemicals that pose health risks. Shockingly, indoor air quality contributes to over 2,000 disability-adjusted life years (DALYs) lost per 100,000 people—twice as harmful as alcoholism and traffic accidents combined.
What Are DALYs?
DALYs, or Disability-Adjusted Life Years, measure the overall burden of disease, taking into account both premature death and years lived with disability. It’s a way for public health experts to quantify the impact of different risks and prioritize intervention efforts. For instance, DALYs help us understand the true impact of smoking, road traffic incidents, and indoor air quality on public health. The fact that poor indoor air quality results in the loss of over 2,000 DALYs per 100,000 people highlights its seriousness, equating it with some of the more notorious public health threats.
Key Indoor Pollutants
Research shows that 75% of harm in homes comes from particulate matter (PM), and 95% of this harm can be attributed to five key pollutants. PM is particularly prevalent, originating from activities such as cooking, traffic pollution that enters the home, mould spores, and even some household products. These particles can penetrate deep into our lungs and contribute to serious health conditions.
Health Impacts
The impact of indoor air pollution is profound, with links to 28,000 to 36,000 premature deaths annually in the UK alone. Vulnerable groups, such as those experiencing fuel poverty or living in overcrowded homes, are most affected. Radon gas, which seeps into homes from the ground, is responsible for nearly 1,000 cases of lung cancer annually in the UK. Poor indoor air quality also exacerbates asthma and other respiratory diseases, significantly affecting individuals’ health and well-being.
Real-World Cases
The tragic stories of individuals like Awaab Isak, a two-year-old who died from exposure to mould in social housing, and Ella, a nine-year-old whose death was the first in the UK to have air pollution officially listed as a cause, underline the real-world consequences of poor indoor air quality. These cases remind us of the critical need for better assessment and monitoring of air quality in social housing. Remote indoor air quality (IAQ) systems are available and could be a game-changer for social housing providers in maintaining healthy living environments.
Moisture and Ventilation in Buildings
Moisture management is crucial to preventing issues like condensation, damp, and mould, all of which affect indoor air quality. Ventilation plays a key role in maintaining moisture balance. Unfortunately, there’s a widespread issue of non-compliance with ventilation standards in the UK, with reports indicating 95% of new builds falling short. In Scotland, even 65% of homes, including newer properties, were found to be under-ventilated.
In our opinion, this is no surprise. Many retrofit installation companies don’t treat ventilation with the proper respect it deserves, and if designers and architects haven’t properly visited the properties they are designing for, it’s all too easy for proposed ventilation measures to fall short.
Ventilation Systems
Traditional natural ventilation, such as trickle vents and intermittent fans, often falls short, partly due to misuse—people frequently close vents to keep out the cold, unaware of the potential impact on air quality. Mechanical ventilation systems, while an alternative, also have limitations. Many fans sold in the UK are unable to maintain adequate airflow continuously without noise issues.
Environmental Monitoring and Air Quality Management
One solution for addressing poor air quality in social housing is environmental monitoring. By implementing IAQ systems, landlords can proactively detect early signs of fuel poverty, mould growth, or issues in vacant properties. Interestingly, tenants are also becoming more involved by collecting their own air quality data, which could change the dynamic between tenants and housing providers.
Strategic Ventilation Management
Improving indoor air quality in social housing involves a strategic approach to ventilation. Housing providers need to map where ventilation is effective and where it’s failing. This includes identifying touchpoints with different teams—such as void management or damp response teams—and ensuring that mechanical systems meet flow rate standards. Coherent actions like appointing a dedicated “ventilation lead” or creating specific communication strategies for different building types can lead to better outcomes.
What we’d like to see done
Indoor air quality is a critical but often overlooked component of health and well-being in social housing. Addressing this requires a combined approach—implementing monitoring systems, ensuring proper ventilation, and involving both tenants and landlords in the process.
By improving ventilation and air quality, we can create safer, healthier homes for those who need them most. But this will only happen if professional installation firms are engaged with the proper understanding of ventilation and mould, and with high quality designs that avoid some of the common pitfalls associated with wall insulation.
We’d like to see all stakeholders give ventilation the proper attention it deserves, and take the time to research and understand the importance of specifying and installing well ventilated retrofit.
Failing that, housing associations and installation firms must listen to residents. People living in properties affected by poor ventilation certainly know about it. Fixing issues after they’ve occurred is not ideal, but must absolutely be prioritised for and budgeted for if we are to avoid some of the mould-related tragedies that have become all too familiar in the media.
Pyramid Eco works closely with housing providers to enhance the comfort, health, and energy performance of their housing stock.
