Airborne fine particulate matter (PM2. 5) is a pollutant that is found in all urban
environments. PM2. 5 is predominantly generated by traffic and domestic fuel combustion …

Previous research has shown that desktop 3D printers can emit large numbers of ultrafine
particles (UFPs, particles less than 100 nm) and some hazardous volatile organic …

Human occupants are an important source of microbes in indoor environments. In this study,
we used DNA sequencing of filter samples to assess the fungal and bacterial composition of …

Indoor carbon dioxide (CO2) concentrations have played a role in discussions of ventilation
and indoor air quality (IAQ) since the 18th century. Those discussions have evolved over the …

Ventilation rates have significant impacts on building energy use and indoor contaminant

We assessed the chronic health risks from inhalation exposure to volatile organic
compounds (VOC s) and particulate matter (PM 2.5) in US offices, schools, grocery, and …

This study examines the human health implications of natural ventilation in California office
buildings. We modeled work-time exposures using field data on indoor and outdoor ozone …

Heating, ventilating, and air conditioning (HVAC) systems in buildings are designed to
provide thermally comfortable conditions and to maintain acceptable indoor air quality (IAQ) …

This paper presents a numerical analysis of the effect of fine particle pollution on the natural
ventilation potential of office buildings in nine European cities. Several years of measured …
