ASHRAE Commits to Developing an IAQ Pathogen Mitigation Standard

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.

VIP 43: Residential ventilation and health

AIVC Technical Note 68 (TN 68) "Residential Ventilation and Health” is one of the outcomes of the work performed under the framework of AIVC’s project “Ventilation & Health” and benefited from contributions by several authors and many structured discussions held during specific sessions at AIVC events. TN 68 summarised studies that prioritise pollutants in the indoor environment and presented a

Issues on humidity environment and health problem

Japan is characterized by high humidity in summer and low humidity in winter. Therefore, summer is in a climatic condition where mold is easy to grow, and in fact, mold damage is occurring. Due to improvement of the thermal insulation and airtightness of houses, the temperature in the room is maintained high even in winter, and mold damage occurs. We will introduce the research we have conducted regarding humidity environment and health problems, and discuss future subjects. The outline is as follows. 

The effect of outdoor pollution and ventilation on Indoor Air Quality

The importance of reducing the ingress of outdoor pollution into the indoor environment is becoming increasingly important as concerns rise regarding the acute and chronic health effects of air pollution. In general, people in developed countries spend typically 90% or more of their time indoors, with the most susceptible individuals, such as the elderly and those with pre-existing medical conditions, spending almost all of their time indoors.

The impact of the quality of homes on indoor climate and health: an analysis of data from the EU-SILC database

Today one out of six Europeans (84 million Europeans, or the equivalent of Germany’s population), report deficiencies regarding the building status. In some countries, that number is as high as one out of three. This puts these buildings in the ‘Unhealthy Buildings’ category, which is defined as buildings that have damp (leaking roof or damp floor, walls or foundation), a lack of daylight, inadequate heating during the winter or overheating problems.
