“…To lower the U-value further for BIPV-vacuum glazing an intermediate air cavity between PV and vacuum glazing was theoretically investigated. The threedimensional heat transfer model showed that this PV-vacuum-double glazing window can achieve a 0.23 W/m 2 K U -value while PV side faced cold outdoor environment and vacuum glazing facing indoor environment, an air cavity is 12 mm and pillar spacing is 60 mm (Huang et al, 2021).…”

“…They illustrate in their work the scale of the impacts unmetered heat flows on the accuracy with which a building's thermal performance may be inferred for two homes at opposite ends of the energy performance scale. The results of the analysis suggest that simple quasi-steady state heat balance methods may be appropriate for dwellings with very high heat loss some researchers analyzed the impact of external heat transfer on building integrated photovoltaic facades for performance evaluation [12][13][14][15]. In fact, wind direction, building geometry, and the interaction between naturel/forced convection on the exterior surfaces have a significant effect on temperature variations in cell temperature.…”

We keep the focus in this paper on the heat transfer coefficients affecting the performance of building for different climatic zones of Morocco. In this respect, the building model is developed using COMSOL Multiphysics based on the convective and radiative equations. Furthermore, the U-shape of the south external wall of the building is modified and tested according to three scenarios (A 0.25 m, B 0.75 m, and C 1.25 m). The results showed a significant increase of radiative heat transfer coefficient (HTC) by 33% and 64.62% by increasing the U-shape from 0.25 to 0.75 m and from 0.75 m to 1.25 m respectively. In fact, the convective coefficient decreases progressively in the U-shape wall. Hence, a maximum reduction of total energy consumption is observed as well as the HTC decreases.

Windows play a significant role in the increase and loss of heat from the building envelope and determine the quantity, quality, and distribution of daylight. A strategy that involves incorporating transparent insulating materials into a double-glazed window offers the potential to provide combined improvements in thermal and daylighting performance. The thermal properties of transparent insulation materials in windows depend on various factors, such as the type of insulation material, thickness, geometry and insulation structure, location, and orientation of the window, among others. The aim of this research is to optimize three criteria: "thickness," "location of transparent insulation relative to window layers," and "direction of the wall with transparent insulation of the building window." The goal is to minimize thermal loads and reduce energy consumption in residential buildings. To achieve this, a real model was selected, and Design Builder software was used to measure the "heating load," "cooling load," and the sum of these two loads as the "total thermal load" for all three criteria in three cities of Iran with different climates: Tehran (moderate climate), Ahvaz (warm climate), and Tabriz (cold climate). The results of the research showed that for the city of Tehran, 3-inch insulation in the middle of the double-glazed window and the south front is optimal. For the city of Tabriz, 5-inch insulation on the inner surface of the window and the western front is optimal. And for the city of Ahvaz, 3-inch insulation on the outer surface of the window and the eastern front is optimal. It is worth noting that the annual heating load and total annual heating load for all three criteria have the highest values in Tabriz city. Therefore, it is recommended to use HSNPS insulation in transparent windows to reduce energy consumption in Tabriz (cold climate).
