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.

Evidence is emerging of endemic non-compliance with ventilation requirements for new homes under Part F of the building regulations.

A comparison between two pairs of households in Switzerland suggests that people do not reliably compensate for lack of mechanical ventilation with more window opening.

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.

Ventilation will be an essential requirement of insulation retrofits under the UK government’s new £1.5 billion Green Homes Grant voucher scheme, Passive House Plus can reveal.

New NUIG study to examine ventilation in A-rated homes

Written by

A research project examining the effectiveness of ventilation systems in low energy homes is one of 45 new sustainable energy projects to receive government funding in companies and institutions across Ireland.

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.

Leading low energy ventilation supplier Sustainable Homes Scotland has advised anyone carrying out a deep retrofit — or building a small low energy dwelling — to consider the benefits of a new generation of decentralised mechanical ventilation with heat recovery (MVHR) systems.

New evidence indicates that decentralised MEV systems – an increasingly popular option, now questions are being raised over the standard “background-plus-intermittent extract” ventilation strategy – can also fail to provide adequate indoor air quality, and may even perform worse than the standard approach in new build homes.
