Calibrate system sensors and actuators within the manufacturer’s recommended interval, maintain the associated records, and create a report for documentation purposes.
System alarms, visible to a building manager or engineer as an email, pager, or text message, or in another form suitable for the building, must be set off when air temperature and humidity levels fall outside the acceptable thermal comfort ranges defined in ASHRAE 55-2004.
Make sure to have at least one humidity sensor in each distinct humidity zone in the building. Humidity zones are not necessarily aligned with temperature zones, so it may be acceptable to have fewer humidity sensors than temperature sensors.
Energy savings is verified by either comparing the calibrated as-built model to the calibrated baseline model, or by comparing the calibrated baseline energy use to the actual metered energy use.
Perform a calibrated building energy simulation model that reflects actual occupancy and weather, after the first year’s energy usage data becomes available. The energy modeler performs the calibrated simulation with the assistance of the M&V provider.
