Indoor Air Monitoring of Ethanol and Benzene in a Pilot Winery Using Active Sampling
… San Luis Obispo’s pilot winery workroom. Air samples were collected during four different wine-making activities: fermentation, fermentation with Brix content testing, post-alcoholic fermentation pressing, and storage/finishing. Average workroom benzene concentrations ranged from 0.05 to …

An Assessment of Indoor Infiltration Parameters for Black Carbon from Residential Wood Combustion and the Spectral Dependence of Light Absorption for Organic Carbon
… was to investigate the infiltration parameters: air exchange rate, deposition rate, and penetration factor. The second part of this study investigated the light absorption properties of organic carbon from residential wood combustion, the dominant fraction of woodsmoke. To assess woodsmoke …

Interaction between thermal comfort and HVAC energy consumption in commercial buildings
… energy consumption in Heating, Ventilating, and Air Conditioning (HVAC) systems and occupants’ thermal comfort in commercial buildings. A numerical model was developed to perform a thermal analysis of a single zone and simultaneously investigate its occupants’ thermal sensations as a non-linear …

Emissions of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate from latex paint
… 2,2,4-trimethyl-1,3-pentadediol monoisobutyrate (TMPD-MIB). Four substrates (gypsum board, plywood, concrete-A and aluminum) and two simplified latex paints (high and low pigment volume concentrations- HPVC and LPVC) containing TMPD-MIB, but no glycols, were employed. Commercial Nippon …

Assessing Human Exposure to Emissions from Ultrasonic Humidifiers
… ultrasonic humidifiers add moisture into room air, but they simultaneously add exposure risks of aerosolized metals from drinking water used as fill water. The inhalation exposure from emitted metals can be overlooked, and thus, co-exposure of inhalation and ingestion and co-exposure to …

A Sensor Network for Real-Time Measurement of Aerosol Movement and Persistence for Infectious Disease Monitoring in ICUs and ORs
Since the COVID-19 pandemic, air quality has become a public concern due to infectious diseases spread by aerosols. A methodology is presented to map the movement and size of particles using a network of low-cost particulate matter (PM) sensors to determine aerosol persistence in operating rooms …

Modeling on single-sided wind-driven natural ventilation
… in buildings, reports have shown that the indoor air quality (IAQ) and thermal comfort are not satisfactory. The lowered productivity due to the bad IAQ could cause $125 billion loss per year and the sick building syndromes could cause $32 billion direct healthcare costs. Most of the problems …
