Preventive Maintenance Sustains Good IAQ
Picture Series 6:
Preventive Maintenance Sustains Good IAQ
- Maintain Up-to-Date Building Records
- Establish an Effective PM Program
- Train Your Key Maintenance Employees on IAQ
- Maintain All Equipment on Time
- Keep a Clean Mechanical Room
- Periodically Check Exhaust Air Flows
- Periodically Check Pressure Relationships
- Periodically Check Temperature, Humidity, and CO2
- Periodically Check Supply Air and Outdoor Air Flows
- Make Use of I-BEAM Forms in Your Maintenance Program
- Monitoring IAQ in Occupied Spaces
- Monitoring PM Throughout Building
Periodically Check Temperature, Humidity, and CO2
Mouse over the picture above to see messages which are referenced in more detail below.
(Hot Spot over CO2 meter.)
- Remember...“Understand the temporal and spatial patterns of temperature, humidity, and CO2 in your building.”
- Historical records of temperature, humidity, and CO2 provide good information on how the mechanical system is functioning over the course of a day and in different seasons. These three measures are reasonable indicators of thermal and ventilation conditions in the space and how those conditions change over time.
- Differences between one area and another also suggest where adjustments may be warranted. Caution is warranted in interpreting CO2 as indicated by I-BEAM.
