“…This section performs a more in-depth analysis on certain materials, methods, and systems related to building envelope energy retrofit. These energy retrofit measures can be applied to building envelope systems and areas such as walls, roofs, windows, floors, façades, and air leakage, and they are applicable in the residential buildings sector [8] as the dominant sector in energy-saving research studies [9]. Three heat gain/loss mechanisms influence building envelope energy retrofit: conduction, convection, and radiation.…”

As one of the biggest energy consumers, buildings are the focus of the energy conservation market, and the building envelope, which has the highest impact on heating and cooling loads, is one of the main targets in retrofit projects. Several materials, systems, methods, and simulation tools are used in these projects, and it is critical to understand the impact of these methods in different locations, their frequency of use, and the effectiveness of market-ready new solutions. In that context, it is necessary to review the energy conservation measures (ECMs) that are suitable for residential building envelope retrofitting, and that are commercially available or under research and development. This paper provides an overview of these ECMs. A literature review was conducted on different building envelope ECMs, including traditional and innovative energy retrofit methods, such as aerogel and phase change materials on opaque and transparent components of existing buildings. Results show that the most effective retrofit projects include bundles of ECMs, and the traditional ECMs can be as effective as more innovative solutions in terms of energy saving. Moreover, computer energy models were created for a typical residential building in the US for cold and warm climate zones to determine the impact of different retrofit approaches based on a sensitivity analysis. Results show that envelope ECMs have higher energy saving potentials in cold climate zones, of up to around 30%, and reducing the air infiltration has the highest impact in both cold and warm climate zones in a typical small residential building.

“…Li et al explored the integration of ceramic fillers into polymer electrolytes, resulting in improved mechanical integrity and enhanced lithium-ion conductivity. [10] In a 2009 study, Shi et al showed MoS 2 , (TMD) characterized by a layered structure, exhibits a direct band gap of 1.8 eV, rendering it a semiconductor. The electrical conductivity of MoS 2 can be modulated through various factors, including the number of layers, presence of defects, and application of an external electric field.…”

Polymer blends of polyvinyl chloride/nitrocellulose/MoS2‐Nafion (PVC/NC/MoS2‐Nafion) were prepared using a casting technique. FTIR analysis revealed chemical interactions between the polymer matrix and filler. XRD analysis was employed to investigate changes in structural phases, while SEM illustrated the agglomerated morphology of the modified blends. The critical role of ionic interaction between Nafion and polymer system in enhancing electrical properties was confirmed through impedance analysis. The introduction of oxygenated functionalities improved surface topography and roughness, as observed by AFM. Electrical conductivity increased from 10−6 S/cm to 10−4 S/cm, accompanied by a decrease in activation energy (Ea). The addition of Nafion decreased bulk resistance, indicating enhanced ionic mobility, as supported by impedance analysis. TG‐DSC analysis demonstrated that MoS2 and Nafion improved thermal properties of polymer blends. The glass transition temperature (Tg) increased by approximately 13 °C and 21 °C with MoS2 and Nafion, respectively. Universal testing machine (UTM) results indicated moderate tensile strength and Young's modulus achieved by MoS2 and Nafion. With increasing Nafion loading, elongation at break rose to around 71 %, showcasing excellent interfacial interaction in polymer‐filler system. The resulting polymer blends, modified by Nafion, exhibited high ionic/electrical conductivity and show promise for hybrid polymer electrolyte applications.

“…The building sector in China accounts for approximately 20% of the country's total energy consumption [ 1 ]. Therefore, building energy savings are crucial to address energy shortages and environmental pollution [ 2 , 3 ]. Building-integrated photovoltaic (BIPV) has shown great potential in achieving carbon neutrality [ 4 , 5 ].…”
