- An Eastern Washington State school district undertook an indoor environmental assessment, study, and intervention - assisted by Indoor Air Quality (IAQ) consultant, Miles Athey - to protect and enhance the learning environment within the district’s elementary schools.
- What everyone can do to contribute to better IAQ, including building managers, tenants, and owners.
- Studies show the impact of good indoor air quality on the health and performance of students and staff.
- Ventilation is the supply of outdoor air to a building. Ventilation rates vary considerably from building to building and over time within individual buildings. Throughout the normal range of ventilation rates encountered in buildings, increased ventilation rates are, on average, associated, with fewer adverse health effects and with superior work and school performance.
- How to go about a simple school walkthrough inspection and what potential IAQ problems to be on the lookout for.
- Use this checklist from EPA to make your IAQ walkthrough inspection as productive as it can be.
- After hypothesizing potential causes, you can perform simple checks to determine if the problem is obvious or if deeper investigation is required.
- Evaluating the symptoms can help narrow down possible causes and can help you determine what checks need to be done.
- Determining where and when problems occur, and by which individuals, can help management determine the source of the indoor air quality problem.
- General process to troubleshooting indoor air quality problems in commercial facilities.
- The Carpet and Rug Institute (CRI) has developed three indoor air quality (IAQ) testing programs that will minimize the potential of emissions from new carpet installations. The programs cover carpet, carpet cushion, and floor covering adhesive products.
- Since there are no official standards for indoor air quality, outdoor air quality measurements set by EPA are often used as benchmarks.
- The common causes of mold growth and ways to prevent it.
- VOC sensors optimize ventilation to help ensure better air quality for occupants and reduce utility costs for building owners.
- Without a long-term commitment to comprehensive environmental management, not even the best high performance school can hope to stay high performing for very long.
- Pathogenic microorganisms are transmitted in many ways in hospitals. One important consideration is the role that the environment plays in pathogen transmission, specifically leading to airborne and waterborne infections.
- Polycyclic aromatic hydrocarbons (PAHs) are a group of over 100 different chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances like tobacco or charbroiled meat.
- 2003 study published in Environmental Health Perspectives (EHP) found 1.8% of population loses job as result.
- Test scores improved when fresh air was properly circulated.
- Current technology allows easy and relatively inexpensive measurement of carbon dioxide (CO2 ) as an indicator to help ensure ventilation systems (for high density occupancy zones) are delivering the recommended minimum quantities of outside air to the building’s occupants.
- Four elements - sources, the HVAC system, pollutant pathways, and occupants - are involved in the development of IAQ problems.
- A brief introduction to making measurements that might be needed in the course of developing an IAQ profile or investigating an IAQ complaint.
- According to the International Journal of Occupational and Environmental Health: "Returning to school after vacations substantially increases the risk of hospital admissions for asthma in children, and this has considerable public health and economic impact."
- There is a widespread perception that carpet cannot be kept clean (sanitary) and that because of its inability to be kept clean, carpet contributes significantly to the deterioration of indoor environmental quality, especially leading to unhealthy indoor air quality. This unnecessary misconception often leads to policy decisions for removing carpet from many environments such as schools, health care facilities, and public agencies.
- There are many factors that can affect IAQ, such as human activity within the building, the building’s construction materials, and the types of heating, ventilation, and air conditioning (HVAC) systems in a building.
- Making the case for comprehensive IAQ management in schools.
- A healthy school needs to engage in a scientific and professional cleaning process to realize its health objectives.
- Regardless of how efficient and effective air-cleaning devices are in removing pollutants, a question still remains about their ability to reduce adverse health effects.
- What benefits of healthy schools have been documented?
