Thermal bridges have a significant impact on the energy efficiency of buildings, but their accurate assessment remains a challenge. In this paper, a novel method for estimating the Ψ-values of thermal bridges and their contribution to the transmission heat losses (Htr,TB) is proposed to solve this problem. The proposed method involves calculating t...

This study investigates mould/fungi growth risk on two different approaches of thermal bridge mitigation. Thermally insulated balconies and thermally broken balconies in Zero Emission Building (ZEB) are reviewed. Linear thermal transmittance (ψ - value), interior surface temperature and mould/fungi growth risk for five balcony designs is performed....

Even though moisture content or relative humidity are one of the basic physical properties of building materials, excessive moisture content in building materials often leads to structural damage and aesthetic changes in the material. This paper presents the results of a study investigating the use of infrared thermography (IRT) to identify and ass...

Transmission heat losses are crucial in assessing a building's energy efficiency. These losses can be determined through numerical calculations, laboratory tests, or in-situ methods. Numerical and laboratory methods require knowledge of the element layers and their thermal properties. In-situ methods, such as the Heat Flow Meter (HFM) method or Inf...

Sabor hrvatskih graditelja Sažetak U ovome radu provedena je numerička analiza prijenosa topline s optimiranjem toplinskih mosto-va za LSF (engl. Light Steel Frame) šuplje izolirane zidove kako bi se smanjili ukupni gubici topline kondukcijom. Analizirani su učinci izolac...

Zahtjevi za kvalitetnom gradnjom iziskuju građevinu bez toplinskih mostova. Kako bi se smanjio i po mogućnosti eliminirao njihov utjecaj na ukupnu potrošnju energije zgrade, još u fazi projektiranja je potrebno obratiti pažnju na njih. Pri računanju toplinskih mostova pomoću računalnog programa, dolazi do brojnih modifikacija elemenata kako bi pror...

In order to maintain the quality of construction for nearly zero energy buildings and to reduce the pressure on construction workers with the addition of the need for faster and simpler structures, the use of cavity-insulated LSF (lightweight steel frame) panels is increasing. Requirements for performance quality, quality of life, and low energy co...
