Estimation of disturbance heat flux in buildings

This paper investigates estimation of disturbance heat flux in a zone using autoregressive integrated moving average model with exogenous inputs (ARIMAX). The model is derived from simple continuous zone model. Data used for estimation is ob-tained from building simulation in IDA ICE. The procedure ex-hibits fast detection of the disturbance heat flux which opens several possible applications in energy-efficient buildings con- trol, like possibility of instantaneous on-off reaction on the zone actuators or better building climate prediction for predictive control.
