We propose a method for identifying thermal building models for HVAC control in the presence of large, unmeasured disturbances. In addition, the method also identifies the effects of those unmeasured disturbances on the output. Our method uses `1-regularization to encourage the derivative of the identified scaled disturbance to be sparse, the motivation of which is physically meaningful. We test our method using training data from both open-loop and closed-loop simulations. Results show that the identified model can accurately identify the transfer functions from flow rate and supply-air temperature to room temperature in both cases, even in the presence of large, unmeasured disturbances, which makes it valuable for MPC applications.
