Environmental Guidelines (Thermostat Settings)
When we are notified of suspected poor indoor air quality (IAQ) in a building, we first contact the building's principal and attempt to obtain some specific information relative to the complaint. The main objective of that conversation is to try to ascertain if there is a specific area and/or person affected by the concern. We then research the work order system for any outstanding equipment repair requests. The next step is sending one of the inspectors to the facility to "check things out".
The inspector checks to ensure that all the equipment is running, and checks the condition of the filters, for room temperature and CO2 levels. Operator errors are discussed on-site with the Building Supervisor and Equipment Operator and that information is noted on the associated report. Work orders are made for needed repairs not already requested. The inspector monitors the problem until it is resolved. There is a computer program used to track and update IAQ issues. We've discovered that most poor IAQ concerns are related to equipment problems.
Equipment Maintains Good Air Quality
- Proper indoor air quality provides a good learning environment and ensures the health and safety of all building occupants.
- In order to provide the proper air quality, all equipment must be operated. Unit ventilators and other air handling equipment introduce fresh outside air into affected spaces when thermostats are satisfied. Generally this fresh outside air appears cold (60 - 65 degrees), but it is mixed with heat and will warm again when the thermostat(s) call for heat. When the equipment is operating as indicated above, it is running properly and should not be turned off. Building occupants should dress according to the season.
Problems / Concerns
- Initial problems and/or concerns should be reported to the school's Building Supervisor. The Building Supervisor will check the equipment and initiate work orders if needed.
- If the equipment is operating properly and there is still an air quality concern, it should be reported to the principal. The Environmental Office should be notified and the concern will be investigated. Any problems found will be addressed and the affected area monitored until corrections are made.
