Two-Dimensional Temperature Fields of Variants Design of a Double-Skin Facade Structure

Abstract

AbstractThe use of a double facade structure in cold climates is relevant today. The global interest in the Arctic territories requires a new approach to design, which will ensure the sustainability of these regions. The promising Double-Skin Facad design predicts a solution to a range of problems. But, it is worth noting that this design has been little studied and requires scientific substantiation. A study was made of the effect of the width of the buffer zone of the double facade on the results of thermal engineering calculations of two-dimensional temperature fields. The Arctic city of Murmansk was chosen as the base region for the study. Six variants of the construction of the “floor—outer wall” node were considered. Thermal calculations for each of the options were performed using the Elcut 6.4 software. The calculation results are summarized in a single table and confirm the hypothesis of the relevance of using a double facade structure in a cold region. The relationship between the width of the buffer zone and the thermal conductivity of the double facade structure is found. With an increase in the buffer zone, the average temperature of the two inner surfaces increases systemically, and, accordingly, the difference in their temperatures decreases. The Double-Skin Facad creates the self-illuminated effect required for the Arctic regions and demonstrates sufficient energy efficiency.KeywordsHeat engineeringDouble skin facadeThermal conductivityEnergy savingArctic regionsLightingArchitecture
