Critical Environment Management System
CEMS (Critical Environment Management System) is a management system that monitors operating status of laboratory rooms to optimize environmental controls. |

Sophisticated Information Management for Energy Saving
CEMS monitors various kinds of data about the laboratory status such as exhaust rates, operating status of fume hoods, etc. It collects data for optimizing the airflow volume controls in a sophisticated style, whereby enabling energy saving and operation cost reduction.
| Management Information | Details |
| Wasted Time | The elapsed time where the hood sash is left open while unattended status is extended |
| Wasted Airflow | The estimated airflow exhausted during the wasted time |
| Hood Status | The list of the current operating status of fume hoods, which can be used for checking before leaving if any hoods remain open |
Information for Safety
CEMS provides safety management information about airflow volume control devices and fume hoods and makes an entry in a history of alarm events when abnormal conditions are detected.
| Management Information | Details | ||
| Unused Airflow | The difference between actual airflow and rated airflow of exhaust fans. Positive airflow margin shows the safety level. |
||
| Rate of Hoods in Use | The number of fume hoods that are in use is monitored. This rate is determined based on the total number of fume hoods belonging to the same unit. |
||
| Fault Monitoring | Logs are kept in the alarm history when alarms are raised as an abnormality is detected in fume hood face velocity, etc.

System Configuration Example
Energy Saving Status Data reports on energy saving status are indicated by room types (reports are provided on daily, monthly, and annual basis). This function will promote researchers' energy saving action. |
Fume Hoods Status Fume hood status (in use / absent / not in use) is listed. This enables efficient laboratory facility management. |
