ANALYSIS OF LINEAR THERMAL TRANSMITTANCE OF A SIMPLE BALCONY THERMAL BRIDGE

Abstract

The linear thermal transmittance of a simple balcony thermal bridge with a uniformbalcony slab and wall was analysed. In a five-parameter model (thickness, length andthermal conductivity of a balcony slab; thickness and thermal conductivity of an adjacentwall), it was found that the length of the balcony slab does not influence the thermaltransmittance, while its dependence on the other two slab parameters is linear. Theinfluence of wall parameters on the linear transmittance proved to be more complicated,but appropriate expressions were successfully found. The study presents the first step inthe search of a semi-empirical formula that can successfully describe the lineartransmittance of a balcony thermal bridge with a homogeneous multi- layer wall.
