ANALYSIS OF LINEAR THERMAL TRANSMITTANCE OF A SIMPLE BALCONY THERMAL BRIDGE

Abstract

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