SEIPS Air Quality Monitoring

Introducing GAMS Air Quality Monitoring

Dear SEIPS Families,

We wish to update you of a new item that we will be including in our newsletter. A report on our school’s indoor air quality monitoring efforts will be issued monthly via the News blog section of our newsletter. As you will remember, we have obtained the monitoring services of GAMS Environmental Monitoring to assist the school in tracking our indoor air quality readings at our campus.

There are multiple sensors placed in strategic locations within the school, which allows GAMS to monitor the indoor air quality in the school’s public areas over a 24-hour period, 7 days a week. The readings include measurements for PM2.5, PM10 and TVOC which are then compared to the accepted measurement levels of WHO, EPA and MEP standards.

The report will be issued monthly and not daily nor weekly, to provide you with substantial results on the air quality at our school. Real time data allows us to make changes on a daily basis to ensure we upload acceptable levels. Air quality changes drastically so it is important to review how we are performing against standards on a monthly basis.

Our monthly report will show bar graphs for PM2.5, PM10 and TVOC. Each chart will show a horizontal dotted line indicating the accepted measurement levels from WHO, EPA and MEP standards. The air quality readings for each location will be illustrated by orange vertical bars. It is important to note that we are working with GAMS to ensure our readings for each location stay within the acceptable levels.

Some points you may want to know prior to using our monthly report:

  • PM is the term for particulate matter found in the air, including dust, dirt, soot, smoke, and liquid droplets. Some particles are so small that they individually can only be seen with an electron microscope.
  • Particulate matter sized 2.5 micro grams per cubic meter are common in indoor environments and are of particular concern for us. This is why we will compare our indoor readings with outdoor readings to ensure our purification systems are working to reduce the presence of these tiny particles. Outdoor readings will be taken from Xinqu outdoor station because this is the nearest outdoor station to our school.
  • TVOC refers to total volatile compounds and includes a very wide range of organic compounds that can be emitted from building materials and products.
  • These organic chemicals have a high vapor pressure at room temperature causing molecules to evaporate and enter the surrounding air as pollutants, for example formaldehyde from paint and adhesives.

We are happy with this initiative as this provides us with an incredible opportunity to track indoor air quality readings and consequently review best practices in the school to further support clean indoor air.


Please find attached the first monthly report of April 2017!


Kind Regards,
