An Expert System for the Cost-Optimal Refurbishment of Buildings

Abstract:

In the present paper we propose a solid theoretical frameworkfor the automatic parametrization of the cost-optimal refurbishment of arbitrary buildings.The parameters describe the structural parts of the building that can be modified or replacedduring the refurbishment process.The methodology also provides the cost-optimal refurbishment costand the corresponding smallest possible total life-cycle operation costconstrained by the available technological and economical limitations.The theory is implemented into the EnergOpt expert system providingfast and accurate answers to cost-optimization problems appearing in common practical applications.The system is built on firm mathematical foundations that is supported by state-of-the-artoptimization algorithms capable of finding good optimums in a short amount of CPU time.The modular structure of the IT implementation facilitates effortless localization in different countries.The application of the system may considerably contribute to the decrease of theheating energy consumption and the corresponding environmental load of the building stock.The practical potential of the technology is demonstrated by the energetic analysisof an existing family house.
