About the Data

The ION database is managed by UBC Energy and Water Services (EWS), which collects data every 5 seconds on electricity (power and energy), hot water, and gas use in campus buildings. In UDL's ION database (Influx database), the data is only updated with every 2 kW change in the electricity power values but the trigger threshold can be modified in the best interest of researchers and operational staff.

Currently, every building has elec_energy and elec_power data streams, but not all buildings have water_volume (hot water volume) and/or gas_volume. Units of the measurement values:

• elec_energy kWh
• elec_power kW
• water_volume cubic meter
• gas_volume cubic foot, cubic meter, or GJ (refer to the image below). The data in the ION database is not converted, so the unit is ft3 if the image indicates "ft3 => m3".

InfluxDB 2.0 Instance

Public users (read permissions only) can log in to our InfluxDB 2.0 User Interface with the following credentials

• Username:public02
• Password: contact UDL ([email protected]) to request password

Public users can also access this InfluxDB instance from InfluxDB command line interface or InfluxDB API client libraries using an authorization token - Please contact UDL ([email protected]) to request a token.

The Python tutorial demonstrates querying the InfluxDB database using the influxdb-client Python module. Please contact UDL if you have any questions.
