Thermal bridges in buildings as a result of urban transformation

Abstract

The paper analyzes the deterioration of energy performance in buildings and construction defects caused by thermal bridges resulting from changes taking place in urban planning, for example in Vojvode Stepe street in Belgrade. The transformation of the urban matrix done over the last 50 years coupled with a time lag in implementation, resulting in partial sequences to completed buildings, has left a number of free side walls (gable ends), which are exposed to temperature influences. In some cases, these walls are adequately heat-treated, but in many others (especially in existing buildings) they are not, causing increased heat loss mould growth, leading to construction damage, and health risks to users. This paper presents a methodology for testing the risk of condensation in a specific example, using the computational support of T Studio software, intended for 2D calculations of thermal bridges, with an emphasis on contact temperature in the interior, relative humidity, and a term that is new to us: Temperature factor.
