Digital Recursive Filters for Building Thermal Modelling

Abstract

The digital recursive filters where proposed as models of the thermal dynamics of the building. The developed wireless system of temperature sensors has been applied in collecting a large body of data. From physical consideration, the first-order recursive filters describe the thermal dynamics in the observed temperature range adequate. Evaluation of the filter parameters was performed using system identification. The proposed models are usable in electronic control systems for energy-saving heating management.
