“…They are the most common fenestration style and serve a variety of important functions in buildings, including: providing occupants with a connection to the external environment, providing thermal comfort, optimum illumination levels, air ventilation, passive solar gain and a possible avenue to exit the building in extreme scenarios [10,11]. They are a popular architectural form and the open scenery through windows in cities with high-rise buildings is a very desirable feature [11].…”

Abstract:Recently, considerable attention has justifiably been directed towards energy savings in buildings as they account for up to 20-40% of total energy consumption in developed countries. In the United Kingdom, studies have revealed that buildings' CO 2 emissions for account for at least 43% of total emissions. Window panels are a major component of the building fabric with considerable influence on the façade energy performance and are accountable for up to 60% of a building's overall energy loss. Therefore, the thermal performance of glazing materials is an important issue within the built environment. This work evaluates the impact of solar window films on the overall energy consumption of an existing commercial building via the use of a case study U.K. hotel and TAS dynamic simulation software. The study results demonstrated that the impact of window films on the overall energy consumption of the case study hotel is approximately 2%. However, an evaluation of various overall energy consumption components showed that the window films reduce the annual total cooling energy consumption by up to 35% along with a marginal 2% increase in the annual total heating energy consumption. They can also provide overall cost and CO 2 emissions savings of up to 3%.

“…An updated review on PCMs integrated into transparent building elements was recently carried out by Fokaides et al [180]. Cuce and Riffat [181] provided a state-of-the-art review on innovative glazing technologies including those incorporating PCMs. Several PCM-glazing systems were also reviewed and described by Hee et al [182].…”

The improvement of the use of renewable energy sources, such as solar thermal energy, and the reduction of energy demand during the several stages of buildings' life cycle is crucial towards a more sustainable built environment. This paper presents an overview of the main features of lightweight steel-framed (LSF) construction with cold-formed elements from the point of view of life cycle energy consumption. The main LSF systems are described and some strategies for reducing thermal bridges and for improving the thermal resistance of LSF envelope elements are presented. Several passive strategies for increasing the thermal storage capacity of LSF solutions are discussed and particular attention is devoted to the incorporation of phase change materials (PCMs). These materials can be used to improve indoor thermal comfort, to reduce the energy demand for air-conditioning and to take advantage of solar thermal energy. The importance of reliable dynamic and holistic simulation methodologies to assess the energy demand for heating and cooling during the operational phase of LSF buildings is also discussed. Finally, the life cycle assessment (LCA) and the environmental performance of LSF construction are reviewed to discuss the main contribution of this kind of construction towards more sustainable buildings.

“…The performance of the condensation prevention was evaluated with the temperature factor f T , as formulated by Equation (2), where the surface temperature at 13 mm from the sightline was used for the calculation of the temperature factor [32]. The higher temperature factors indicate that the window can withstand the surface condensation at lower outdoor air temperatures.…”

“…Windows are one of the weakest points in building envelopes from the viewpoint of the thermal insulation [1,2]. It is therefore important to enhance the thermal performances of windows to reduce the heat loss through windows, which can contribute to the reduction of not only condensation risks, but also the total heating energy of a building.…”

This study investigated the impact of thermally improved spacers (TISs) on the condensation prevention and energy saving performances of residential windows. The temperature factor and total U-value were analyzed with the two-box model, by which the TISs are represented with the equivalent thermal conductivity. The results showed that the TISs could increase the temperature factor by up to 12%, and this significantly improved the condensation prevention performance. In addition, it was proved that the TIS enables the prevention of the condensation at an outdoor temperature that is 4.2 • C to 15.7 • C lower compared with the conventional spacer. Also, it was shown that the TISs reduce the total U-value by an amount from 0.07 W/m 2 K to 0.12 W/m 2 K, implying that the heat loss through the window is reduced by a rate from 2.8% to 8.2%. In addition, the results of the whole building energy simulation proved that the TISs can reduce the annual heating-energy consumption by a rate from 3.0% to 6.3%. The results were then used for the development of monographs to determine the equivalent thermal conductivity of a window spacer that can meet the performance criteria in terms of condensation prevention and energy saving.
