BACKGROUND Indoor air pollutants (IAPs) cause multiple health impacts. Prioritizing mitigation options that differentially affect individual pollutants and comparing IAPs with other environmental health hazards require a common metric of harm. OBJECTIVES Our objective was to demonstrate a methodology to quantify and compare health impacts from IAPs. The methodology is needed to assess populat...

A study was conducted in the US EPA Indoor Air Quality (IAQ) Research House to determine the spatial and temporal distribution of chlorpyrifos following a professional crack and crevice application in the kitchen. Following the application, measurements were made in the kitchen, den and master bedroom over 21 days. Airborne concentrations were collected using both polyurethane foam (PUF) and th...

It has been reported that there is a large issue regarding the IEQ in schools and classrooms as they often do not have mechanical ventilation system or operate it to save on electricity bills. However, measurements reports from existing research indicate indoor air temperatures CO2 levels are way outside recommended values manual venting by opening windows during brakes sufficient. This become ...

Indoor air quality (IAQ) in educational buildings is a key element of the students’ well-being and academic performance. Window-opening behavior infiltration, generally used as sole ventilation sources existing buildings, often lead to unhealthy levels indoor pollutants energy waste. This paper evaluates conditions natural classrooms order study how climate affect For that purpose, impact infil...

Sustainable building design, such as the Passivhaus standard, seeks to minimise energy consumption, while improving indoor environmental comfort. Very few studies have studied air quality (IAQ) in homes outside of Europe. This paper presents particulate matter (PM2.5), carbon dioxide (CO2), and total volatile organic compounds (tVOC) measurements first residential Latin America. It compares the...

Under the assumption that information can impact perception, most research on human sensation and satisfaction with indoor environmental quality (IEQ) parameters has been conducted respondents uninformed about test conditions. Therefore, researchers know little of perception. These potential effects are increasingly relevant as quantitative environments becomes accessible via low-cost, wireless...

Employees work long hours in an environment where the ambient air quality is poor, directly affecting their efficiency. The concentration of particulate matters (PM) produced by interior renovation shopping malls has not received particular attention Macao. Therefore, this study will investigate indoor (IAQ), PM2.5, large-scale mall projects. This collected on-site PM data with low-cost portabl...
