- | ====== Data for HVAC analytics ====== | ||
- | ==== General information ==== | ||
- | Building operation is (or at least shall be) determined by a schedule. Therefore we need some information about regimes in the building (at least non-stop operation vs. office hours determined operation). This applies to all analytical topics listed below. | ||
- | We do not require outdoor temperature, | ||
- | |||
- | Bellow is a list of recommend variables for each analytical topic. | ||
- | ==== Heating circuit ==== | ||
- | ^ Signal ^ Type ^ Note ^ | ||
- | | Supply water temperature | measurement and setpoint | | | ||

- | ==== Air handling unit ==== | ||
- | AHU is more complex appliance and there is no unified data set for analysis. Usually, AHU is described by 15 - 30 relevant variables. | ||
