In our final post on ‘The Inside Story’ a study published in January 2020, we focus on some of the recommendations made by the authors to improve indoor air quality.
The Royal College of Paediatrics and Child Health estimate that 3.6m UK children live in poor quality housing and spend on average only 68 minutes outside each day. They majority of time is spent indoors, at school or at home.
The report highlights the challenge facing poorer families to keep their homes warm whilst balancing this with good indoor air quality. In addition, they have less choice about the quality of their homes which often makes them more likely to encounter health problems relating to poor ventilation. This was discussed in our second post of this series.
The report draws attention to the fact that current building regulations focus mostly on energy efficiency rather than air quality for new buildings. Whilst there are recommended minimum levels of air flow through buildings, the regulations do not go as far as to set standards for air quality, nor do they apply to retrofit upgrades of older buildings. This needs to change.
The report calls for a national strategy to be developed, led by a committee of representatives of local authorities, child health professionals, building industry leaders, and national government.
It recommends that the strategy should include providing information to the public about maintaining healthier indoor environments, and processes for occupants of poorer quality housing to report problems that can be actioned.
The authors recommend the committee should specifically be required to:
In February 2020 new restrictions on the sale of domestic fossil fuels and untreated ‘wet’ wood were introduced in the UK. The regulations target a reduction in combustion of fossil fuels, and represent an important step forward in minimising exposure to the harmful effects of fine particulate matter, a bi-product of burning untreated wood and coal indoors.
This is the first time the UK government has legislated specifically on indoor air quality, but it remains unknown how this will be enforced when it comes into effect from 2023.
In 2017 Scotland introduced new energy efficiency standards which were adapted to include indoor air quality. Landlords will be required to collect data on air quality by measuring temperature CO2 and humidity levels. Going forward this data will be used to set new standards for indoor air quality from 2025.
UK building regulations have still got a lot of catching up to do on legislation to set safer levels of indoor air quality. When compared to other regulations concerning safety such as food packaging, progress is slow. Other European countries seem to be leading the way. For example, Finland already regulates on acceptable levels of specific pollutants such as particulates and formaldehydes in all new buildings.
The report highlights that responsibility cannot only be placed with families to take preventative steps to improve air quality. It recommends new guidance which includes:
