In this study, questionnaire survey and field measurement were conducted for the houses with the elderly in urban and rural areas across 6 regions of China, during heating period. As the results, the prevalence of hypertension was found around 40% in both urban and rural areas. In the northern regions, the room temperature in urban residences was stable at around 20°C, and in rural areas this temperature rarely reached 20°C but it fluctuated greatly.
On May 15th, 2023 ASHRAE announced the completion of the first draft of its standard for maintaining healthy indoor air quality (IAQ), with final approval expected in June and publishing anticipated in July.
In November 2022, the Lancet COVID-19 Commission Task Force on Safe Work, Safe School, and Safe Travel released a report proposing new Non-infectious Air Delivery Rates (NADR) for Reducing Exposure to Airborne Respiratory Infectious Diseases, exceeding the current minimum standards, and aiming to help mitigate infection risk and promote health.
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.
