MicroLogPRO II – For investigative Indoor Air Quality (IAQ)


Thermal conditions – temperature and relative humidity constitute the thermal environment and play an important part in the school environment. Data loggers can be used for investigating IAQ in schools by locating the source of the problem and finding the suitable corrective solution.

Application:   HVAC system monitoring and validation   

Organization:  International K-12 school in Singapore

 

Background:                               

Indoor Air Quality (IAQ) in schools may have an important influence on kids’ well-being. Four factors determine IAQ in schools: source of indoor air pollution, heating, ventilating and air-conditioning systems (HVAC), pollutant pathways and the people themselves. Failure to prevent or respond promptly and effectively to IAQ problems may cause serious health, cost and educational consequences such as: increasing the potential for long-term health problems for students and staff; affecting the students learning environment, comfort and attendance; reducing performance of teachers and staff because of discomfort, sickness; accelerating deterioration and reducing efficiency of the school physical plant and equipments.[i]

About the Customer:

An International school in Singapore established more than 40 years ago. This school is recognised as one of the leading international schools in the world and offers a mission-driven, values-based international education to students from more than 70 nationalities. It is a K–12 (Kindergarten through 12th grade) school, with multiple campuses and nearly 6,000 students.

 

Key Customer Challenges:

  • Some of the school’s classrooms had undergone major air-conditioning equipment modifications a year ago.
  • As the school suspected indoor air quality issues, particularly associated with excessive air moisture (temperature and relative humidity) in the internal environment of the classrooms, they required information regarding these parameters in their classrooms.
  • To acquire this information the school decided to start an investigative Indoor Air Quality (IAQ) study.
  • The objectives of this study are to provide the school with information regarding the indoor environmental parameters of each classroom, specifically during times that the rooms are occupied and provide objective figures of what is happening to the Indoor air quality, particularly temperature and relative humidity when the air-conditioning is operated, in bypass and off modes.


MicroLog Solution:

The diagnostic study at this international school was conducted by Fourtec’s distributor in Singapore, IAQ Consultants. MicroLogPRO II Temperature and Humidity logger (EC850) was used to provide comprehensive information about the IAQ environment during the 3.5 days study of four classrooms. Data logging equipment was deployed around the study site to trend the continuous patterns of air temperature and relative humidity (RH) in these 4 classrooms, inclusive of the adjoining corridor on 2 levels inside the Campus. Twenty-three EC850 data loggers were placed in these classrooms to continuously monitor the ambient air temperature and relative humidity levels. The MicroLogPRO II devices were situated in various locations inside each classroom – suspended from the ceiling board, on top of the ceiling board, below the air-conditioning grilles, near the entrance door at head height and below the desk. The data loggers monitored relative temperature and humidity levels during the whole day over the 3.5 days at various times.

The study provided detailed information to support its source findings, concluding with the most likely causes for the suspected moisture problems inside of the classrooms as conveyed by the international school. Analysis of the data and discussion around the interpretation of the gathered data subsequently validated the recommended corrective actions and remediation protocols.

 

Measurable Results:

 

  • Portable, compact, easy to deploy monitoring - The MicroLogPRO II Temperature and Humidity data logger proved to be an ideal solution to conduct a short term investigative Indoor Air Quality (IAQ) study, as it is portable, compact, easy to deploy in classrooms and easy to use.
  • Online data view - 4-digit data display enabled the company conducting the study online view of the data if needed during the study, without connecting the devices to the computer.
  • Free analysis software – The data recorded via the MicroLogPRO II data loggers can be analyzed with the free DataSuite software, enabling device configuration, data monitoring and enhanced analysis functionality. 


Customer’s Feedback:

“The MicroLog PRO II temperature and humidity data logger enabled us to conduct the investigative Indoor Air Quality (IAQ) study easily and efficiently. The free DataSuite analysis software was used for interpretation of the gathered data and finding the proper corrective actions”.
