Exposures in homes constitute the major part of exposures to airborne pollutants experienced through the human lifetime. They can constitute from 60 to 95% of our total lifetime exposures, of which 30% occurs when we sleep.
Due to extreme increases in energy prices in European countries (as well as other non-European countries), building users may be tempted to take energy saving measures because they can no longer pay their energy bills. This in turn may have adverse effects on the indoor air quality - especially in older and badly insulated homes. This article gives some elementary advice on what people should and shouldn’t do in cold and temperate climates where indoor heating is normally needed in winter.

Common metrics used for assessing air quality are based on guidelines and/or standards for regulating concentrations that should not be exceeded over a period. Exceeding those values would represent problematic situations. A lack of agreement on appropriate norms or standards deem this approach sub-optimal. Moreover, this approach does not relate a proportion of exceedance to specific health outcomes.

In response to the COVID-19 pandemic, many organizations have recommended improved ventilation to reduce the risk of indoor airborne infectious disease transmission. These recommendations include increasing outdoor air rates and filtration efficiencies, as well as verifying that ventilation systems are operating as intended. There have also been many recommendations to monitor indoor CO2 concentrations as indicators of ventilation or infection risk, in some cases with quantitative concentration limits.
In January 2023, the Environmental Law Institute (ELI) with funding from the U.S. Environmental Protection Agency (EPA), released the report: "Ventilation in Schools: A Review of State Policy Strategies".
In the framework of The Trento EEMI Bauhaus Week, the European Mortgage Federation - European Covered Bond Council (EMF-ECBC) released a video-”call to action” (for distribution to 2000 banks and 5000 major companies) about the decarbonisation of buildings and the heat mitigation in cities.
On December 7, 2022 ASHRAE’s board of directors announced its commitment to support the expedited development of a national indoor air quality (IAQ) pathogen mitigation standard. The goal is to finalize the consensus-based, code enforceable standard within six months.
