New radon maps, launched by the Environmental Protection Agency today at the National Radon Forum, show an increased risk from radon in Ireland, with 170,000 homes now predicted to be at risk of radon exposure above the national reference level.

Coventry University research has found that 40 per cent of primary school classrooms examined in a study did not have an adequate ventilation rate to combat the spread of Covid-19.

A new analysis of the exposure of London households to indoor pollutants highlights “systematic inequalities” in exposure, overwhelmingly driven by factors beyond the control of those people worst affected.

A big part of a comfortable household is having good indoor air quality and a comfortable air temperature. Mechanical ventilation with heat recovery (MVHR) is an efficient way of providing the necessary ventilation with little heat loss.

When it comes to air pollution, we tend to worry most about things like traffic fumes and solid fuel burning — or when it comes to indoor air, condensation, damp and mould. But one of the biggest threats in the air we breathe comes from something we are exposed to almost every day, but rarely think about: cooking. John Hearne reports on the evidence for how cooking affects indoor air quality, and what we can do about it.

Researchers from the School of Physics at NUI Galway are seeking to recruit 100 households to measure indoor environmental air quality within Irish homes that have been built to be highly energy efficient, by deploying remote sensors within the homes.

The National Standards Authority of Ireland has appeared to acknowledge a major discrepancy spotted by Passive House Plus in SR 54, its code of practice for the retrofit of homes, that could give rise to inadequate ventilation and poor indoor air quality in some dwellings upgraded to the code.

As previously revealed in Passive House Plus, the evidence appears to indicate that natural ventilation systems don’t adequately ventilate our homes. But does mechanical ventilation perform any better?

A recent study instigated by the American Environmental Protection Agency has identified indoor air quality as one of the top five urgent environmental risks to public health.
