| Outline of Final Research Achievements |
Methods for on-site measurement of building thermal performance system parameters such as coefficient of heat loss and infiltration rate are very important. On-site measurements are exposed to changing meteorological conditions and these parameters should generally be estimated in a multi-zone model such as inter-zone flow rates. In this regard, a simultaneous ordinary differential equation model is converted into regression equation and system parameters estimation theory including reliability evaluation has been developed on the basis of least squares. We have improved a system parameter identification theory and uncertainty analysis method using least squares. A prototype measurement systems for both thermal and ventilation performance have been developed and were tested for the operational confirmation in an apartment house. The system can be applied to 10 rooms at maximum and two PCs are used for wireless control of the devices. The experiment results showed appropriate results.
