Abstract: This paper proposes a novel method to implement a first-order equivalent thermal parameter (ETP) model, a commonly used model to provide building thermal response prediction for advanced building controls. This method reformulates the existing implementation method to allow the ETP model to capture varying heat disturbance and non-linearity in the zone temperature evolution. It also guarantees that the prediction from the ETP model is always reasonable by considering more physical constraints. To evaluate performance, we implemented an ETP model with the proposed method for a medium-office building and predicted the zone temperatures for one day. Prediction results are compared against those from an ETP model implemented through a common approach and a lookup-table model. Results suggest that the ETP model implemented by the proposed method can yield more accurate results compared to the other two models; additionally, the ETP model implemented by the proposed method demonstrates similar capabilities in capturing non-linear behaviors as the lookup-table model.
