-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.
+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). We do not read this information directly from BMS. It shall be defined by facility management in order to validate BMS setting. This applies to all analytical topics listed below.
-We do not require outdoor temperature, we use independent data source.

+AHU is a complex appliance and there is no unified set of variables that are need for AHU analysis. We try to use all data that are provided. Usually, AHU is described by 15 - 30 relevant variables.
+Information about heat recovery type (plate, wheel or glycol) is also needed as well as operation schedule.
