“…The global energy sector is facing increasing challenges, including reducing the environmental impact of buildings, which is now inextricably linked to the pollution resulting from the indiscriminate use of non-renewable energy sources [1][2][3]. Many buildings in the European Union (EU) still do not meet the energy efficiency standards required to move to a sustainable consumption pattern [4,5].…”

“…The third phase is the evaluation of the potential of each intervention, while the fourth phase is dedicated to the implementation of the renovation solutions, which are finally validated by the results in the fifth phase [11]. Numerous studies already provide tools and context for reducing energy consumption around the world [3][4][5][6][7][8][9][10][11][12][13][14]. Retrofitting existing structures can significantly reduce energy consumption and greenhouse gas emissions worldwide.…”

Combining CAD Modeling and Simulation of Energy Performance Data for the Retrofit of Public Buildings

The retrofit of the most energy-intensive buildings represents an opportunity to improve their energy efficiency or to reduce their energy demand. This paper proposes combining computer-aided design (CAD) modeling and the use of energy efficiency software to build a methodology for calculating, visualizing and analyzing building parameters in order to provide retrofit scenarios. Five retrofit scenarios were implemented using the energy software, including the initial operating cost, capital cost and payback period to be evaluated. At the same time, a three-dimensional CAD model was created to perform daylighting and shading simulations to visualize and design the role of building orientation under actual use conditions. These retrofit scenarios were evaluated individually and then combined to examine their performance in terms of cost-effectiveness and energy efficiency. The simulation results show the importance of the building’s orientation, as this directly affects the thermal properties of the walls and openings, as well as the daylighting areas. The simulation results were also used to define the parameters that affect the interoperability of the retrofit solutions. Finally, in addition to the significant reduction in calculation time, the coupling of the CAD software with the energy efficiency software allowed access to information that was not available at the outset.

“…With increasing global energy consumption and the environmental impact of traditional energy, it is inevitable that traditional fossil fuels have to be replaced with economic and sustainable clean energy [1–4] . By using hydrogen or methanol as fuels and oxygen as reductant, fuel cells are important next‐generation devices with high efficiency, high power/energy density, fast refueling, and zero carbon emissions [5–6] .…”

The oxygen reduction reaction (ORR) is central to modern energy storage and conversion technologies for grids such as fuel cells and electrolyzers, but challenges remain due to the lack of reliable, economic, and durable electrocatalysts. Here, we develop single‐crystal conductive black titanium (Ti4O7) nanosheets (NSs) as a new precious metal carrier based on sacrificial hard templates and ultrasonic‐assisted peeling, and deposit Pt clusters on Ti4O7 NSs induced by wetness impregnation under the irradiation of visible light (VI; 650 nm). Pt/Ti4O7 NSs provide Ti3+, Pt2+, and Pt0+ continuous active sites for the ORR multielectron process, achieving synergy among them. The assistance of visible light not only makes a more uniform and smaller distribution of Pt nanoclusters, but also strengthens the charge transfer, thereby constructing a strong metal‐support interaction interface. VI−Pt/Ti4O7 NSs show superior initial oxidation potential and a mass activity of 1.61 A mg−1Pt at a E1/2=0.91 V, which is nine times higher than that of commercial Pt/C. This work provides an effective strategy for achieving high‐value applications of titanium sub‐oxides and further explores the enhanced interface in metals TinO2n‐1 by light radiation.

“…Stepped-up usage of renewable energy sources will support fulfilling growing power demand while also curtailing the conflicting environmental effects of energy use (Abdul et al 2021 ; Tanveer et al 2021 ). Improving RE is also critical for achieving long-term sustainable development goals (Haseeb et al 2019 ; Deshmukh et al 2021 ). Furthermore, non-RE energy sources like fossil fuels (coal, natural gas, and oil) degrade the climate and contribute to global warming (Shahsavari and Akbari 2018 ; Alizadeh et al 2020 ).…”

Ideal energy policies based on the identification of main obstacles might indorse the growth of renewable energy. In light of the importance of promoting entrepreneurship in renewable energy resources, the current study examined the barriers to develop renewable energy entrepreneurship in Pakistan. As a result, the current study proposes a systematic approach for prioritizing hurdles to entrepreneurship based on their relevance. The research was split into two parts. To begin, a literature survey and interviews with experts were used to identify potential obstacles. Second, the Pythagorean fuzzy analytical hierarchical process (PF-AHP) approach was hired to finalize and categorize the challenges. Twelve barriers were finalized, and they were then divided into four categories. Finally, PF-AHP was used to determine barrier weights and ranks. The final results showed that the legal and regulatory framework obstacle category is the most essential among the main categories, while the overall ranking of obstacles revealed that the lack of policy is more vital than the other twelve sub-barriers in various groups.
