Kampusareena building automation

Measurements from the Siemens Desigo building automation system of Kampusareena including data related to indoor conditions, ventilation, heating and cooling. For most spaces in Kampusareena available data includes temperature, air quality and occupancy.

This data has been collected so that a new value for a measurement is obtained only when the value changes. Thus the time interval between values varies greatly. It can be anything from less than a second to one day.

Schematics and diagrams of the building are necessary to understand many of the measurements. These can be requested from the building owner, University Properties of Finland.

NOTE: In the available measurements lists some measurements are marked confidential. They are related to spaces used by private tenants of Kampusareena. This data is categorized as sensitive and extra care has to be taken when using this data. Tenants cannot be identifiable from anything produced from the data. See the Kampusareena group for more info about under which conditions this sensitive data can be used.

Notes:

• No measurements are available between 19th of February 2024 and 23th of September 2024.

• After 19th of September 2024 there are no measurements for ids between 12088 and 12519

The measurements are organized in a hierarchy that consists of 4 components. These are listed for each measurement in the available measurements lists and are the following:

• System: The wider system or subject the measurement is related to. For example water or HVAC (heating, ventilation and air conditioning).

• Subsystem: Indicates the part of the wider system. For example KL01 (district heating) or iv01 (Air conditioning heating/cooling network). Names are often directly from the building automation system and their meaning is hard or impossible to understand. A list of possible values can be found from below.

• Location: Indicates the physical location or target of the measurement. Can be a room number or name of a part of a system.

• Type: Indicates what is measured for example temperature or pressure.

Name

Measurement names are based on their names in the building automation system. For example a wall mounted temperature sensor can be found from the measurement list based on the text on it for example TCA514'TE20. This example sensor is the temperature sensor TE20 for the temperature controller TC of room A514. If there would be a second similar sensor for the same location it would be called TCA514'TE21. Third would be TE22 and so forth. Second example TK08'TF01'Pwr would be power for air supply fan 01 of air supply unit 08. Third example: KJA528'KF01'TV60 is the cooling valve tv60 for air fan 01 of convector A528
