This paper announces the sequel of the report which appered in the previous work of this publication. An approach to the estimation of the thermal performance of residential room is presented. Then the performance is defined as the directional heat loss coefficient and heat capacity according to each orientation. The fundamental equation describes the heat balance with the weighting functions and includes unknown parameters which mean the thermal performance of room. The equation is non-linear in regard to the parameters. It is not easy, therefore, to estimate the parameters. In order to avoid this difficulty the equation is separated into two parts which are the heat storage term and the heat excitation one, so the former contains unknown state. Then it is necessary to estimate the unknown state, too. This approach is based on the optimal fixed-interval smoother and parameter identification methods (e.g. generalized least squares method). Using them mutually, an alternative algorithm for the system identification problem with the unknown state and parameters is obtained. It is expected that the above algorithm is recursive if it is applied to the field measurement. For the purpose of supporting the justification of the approach presented here, results of numerical experiments are also demonstrated.
