resistance of heat transfer

Динамічність оптимального термічного опору стін будинків

In this paper the results of mathematical provement of economical optimal thermal resistance of a building wall are presented at condition of both heat energy and thermal renewal cost change on future. There are presented comparation of technical and economical indexes at external walls renewal at the different characteristics of enclosure constructions.
Purpose is to analyze the technical and economic factors that determine economic feasibility insulation of external walls subject to changes in the cost of heat and renewal in future.
