  1. Effect of Fiber Material on Ozone Removal and Carbonyl Production from Carpets

    Indoor air quality is affected by indoor materials such as carpets that may act as sources and/or sinks of gas-phase air pollutants. Heterogeneous reactions of ozone with carpets may result in potentially...

  2. Longitudinal Assessment of Thermal and Perceived Air Quality Acceptability in Relation to Temperature, Humidity, and CO2...

    Thermal acceptability (TA) and perceived air quality acceptability (PAQA) are typically analyzed in climate chambers or cross-sectional field studies. Individual factors, such as expectations and perceived...

  3. Ozone Interaction with Indoor Building Materials and HVAC Filters

    As modern life develops, humans spend most of their time inside buildings. Understanding the effects of different building materials that exist indoors on indoor air quality is crucial to ensure comfort,...

  4. Bioaerosol Deposition on an Air-Conditioning Cooling Coil

    This study is concerned with the role of a fin-and-tube heat exchanger in modifying microbial indoor air quality. Specifically, depositional losses of ambient bioaerosols and particles onto dry (not cooled) and...

  5. Investigating CO2 Removal by Ca- and Mg-based Sorbents with Application to Indoor Air Treatment

    Indoor carbon dioxide (CO 2 ) levels serve as an indicator of ventilation sufficiency in relation to metabolic effluents. Recent evidence suggests that elevated CO 2 exposure (with or without other...

  6. A Regression Approach for Estimation of Anthropogenic Heat Flux Based on a Bottom-Up Air Pollutant Emission Database

    A statistical regression method is presented for estimating hourly anthropogenic heat flux (AHF) using an anthropogenic pollutant emission inventory for use in mesoscale meteorological and air-quality modeling....

  7. Real-Time Monitoring of Personal Exposures to Carbon Dioxide

    Elevated indoor CO2 levels are indicative of insufficient ventilation in occupied spaces and correlate with elevated concentrations of pollutants of indoor origin. Adverse health and well-being outcomes...

  8. Climate and More Sustainable Cities: Climate Information for Improved Planning and Management of Cities...

    In the last two decades substantial advances have been made in the understanding of the scientific basis of urban climates. These are reviewed here with attention to sustainability of cities, applications that...

  9. National Urban Database and Access Portal Tool, NUDAPT

    Based on the need for advanced treatments of high resolution urban morphological features (e.g., buildings, trees) in meteorological, dispersion, air quality and human exposure modeling systems for future urban...

  10. Comparative Estimates of Anthropogenic Heat Emission in Relation to Surface Energy Balance of a Subtropical Urban...

    Long-term eddy covariance measurements have been conducted in a subtropical urban area, an older neighborhood north of downtown Houston. The measured net radiation (Q*), sensible heat flux (H) and latent heat...
