“…In addition, new reflective thermal insulation was incorporated, improving the enclosure's performance, while decreasing thermal transmittance thanks to a thickness of only 3.0 cm (Fig. 8) [14]. We suggest replacing the existing aluminium window frames with high thermal transmittance by aluminium frames with a thermal bridge break based on a double-glazed sheet with an inner chamber since, as illustrated in the thermographs (Fig.…”

“…The PCM sheets were placed in this chamber and acted as energy storage. The accumulated energy is gradually released to the upper slab in the form of heat both by conduction and by radiation [14]. The theoretical operation of the PCM conditioning system is detailed below based on four different scenarios.…”

“…The reduced insulation thickness allows for a bigger chamber and consequently, a larger air flow can circulate. The major energy improvement measure to reduce annual energy demand consists in reducing U thermal transmittance of the enclosures making up the building's thermal Table 2 and is expressed in percentages [14]. The proposed intervention also considers replacing the stone finishing material with a double ceramic sheet of great durability and strength together with an internal mesh reinforcement [5].…”

Building energy consumption and ways to reduce it have drawn increasing attention in recent decades. Thermal transmittance is not only a code-enforced parameter during the design and retrofit phase of building assemblies, but also strongly related to the accuracy of whole-building energy modeling. There are several existing methods to measure the building envelope thermal transmittance, and with the development of new techniques, more practical and precise measurement methods have been explored. The study discussed here focused on comparing methods to measure the building envelope thermal transmittance, both in laboratory and for in-situ measurement. Typical research studies related to the Hot Box Test Method, the Heat Flow Meter Method and the Infrared Thermography Method are described and compared. This paper provides a state-of-the-art review of the up-to-date measurement methods for building envelope thermal transmittance and provides alternatives for engineers, architects and researchers to practically measure the building envelope thermal transmittance.

“…Albatici et al [32] [33], Nardi et al [34] and Dall'O et al [35] used an empirical correlation based on the wind speed to estimate the heat transfer coefficient. Bienvenido et al thoroughly studied the influence of the correlation chosen for the internal [36] and external [37] coefficients on results of quantitative IRT methods. Finally, Ibos et al [38] implemented and compared three IRT methods to ISO 9869-1 [9] and pointed out the high dispersion results obtained.…”
