It is important to measure the indoor air quality (IAQ) to ensure that occupants in a building are healthy and productive. OBEM introduces widgets that measure indoor air quality parameters like temperature, humidity, particulate matter (PM2.5 and PM10), total volatile organic compounds (TVOC), and carbon dioxide. OBEM measures each of these parameters during the occupied schedule of the building and also when the building is unoccupied to show information to ensure that occupants are healthy and productive.
The following widgets are available in the Clean Air Delivery and Air Quality tab at the building level:
- Clean Air Delivery Score
-
The Clean Air Delivery score is an indicator of the HVAC system to deliver enough clean air to the space. Cleaning the air through ventilation, circulation, and filtration reduces the chance of disease transmission due to airborne pathogens in the space. The score is calculated using HVAC system parameters, space parameters, occupancy level, and whether or not occupants wear masks.
Higher Indoor Air Quality scores result in the lower chances of infection spread.
- A score between 0 to 50 indicates high chances of infection spread
- A score between 51 to 80 indicates medium chances of infection spread
- A score between 81 to 100 indicates low chances of infection spread
- Indoor Air Quality Score
-
The Indoor Air Quality score is an indicator of how clean the air is in the space. This score is calculated using data measurements of temperature, humidity, carbon dioxide levels, particulate matter (PM10 and PM2.5) levels, and total volatile organic compound (TVOC) levels in the space. Sensors provide the values that are then compared against thresholds to arrive at the calculated score.
Higher Indoor Air Quality scores mean better air quality.
- A score between 0 to 50 indicates poor air quality
- A score between 51 to 75 indicates medium air quality
- A score between 76 to 100 indicates good air quality
- Low Clean Air Delivery Alerts
- Displays areas with a low clean air delivery score.
- Low Indoor Air Quality Alerts
- Displays areas with a low indoor air quality score.
- Building Area Navigation
- Displays the Clean Air Delivery Score and the Indoor Air Quality Score information for the building you select from the Space Tree. Click a floor name under the building to expand a list of zones below that level. Click a zone or wing name to view information about that space.
- Energy Cost
- Click the Trend icon to view the energy cost trend for the last 30 days.
- Clean Air Delivery and Indoor Air Quality Score
- View the trends of the Clean Air Delivery score and the IAQ score at the zone or wing level for the last 30 days. Select the zone you want to view in the Area section. This helps you to establish the correlation between air quality being poor and what parameters contributed to the score.

The IAQ parameters graph shows how the IAQ parameters for the zone change throughout the day and shows up to 30 days of history. You can select up to two different parameters to display on the same graph at the same time, for example, CO2 and PM2.5, and you can select up to three different IAQ devices for each parameter to compare different device readings on the same graph.
