OPTIMIZATION OF A “SANDWICH” STRUCTURE FOR THE INSULATION OF A PREFABRICATED WOODEN HOUSE

Abstract

This paper aims to determine an optimal solution in terms of cost to the problem of determining a structure composed of layers of different material which ensures a required heat transfer from inside a building to outside them ( a suitable insulation at a minimum price) . The problem is placed in a zone of interference between the heat exchange and construction research domains. A theoretical study on the method of optimizing the objective function cost price considering heat transfer by laminated flat surfaces was carried out, and experimental measurements were made in order to validate the results. The literature reveals the existence of a corrective coefficient for each insulation material but not for structures of the type we studied. Knowledge of these factors allows the design of dimensionally and thermally constructions having similar composition as those in the study and allows optimizing the performance in terms of costs.
