“…The research results provided useful insights for de-carbonization of urban buildings. Kinay et al [25] investigated the renovation wave of residential building stock targets for carbon neutrality using case studies in Finland and Türkiye, and Zhang et al [26] carried out field studies in Beijing, the capital city of China, with a deep investigation of retrofitting old residential buildings without destroying traditional and historic constructions. Furthermore, Charles et al [27] and Adua et al [28] stated the importance of energy saving for existing buildings, especially the reduction in operation terminal energy usage and consumption of building services systems including lighting, ventilation and space air conditioning.…”

With the progress of urbanization in China, the energy-saving renovation of a large number of existing buildings, especially old buildings, has become an important project for the green and low-carbon development of urban renewal. This paper takes the old brick school building in a university in Chengdu as an example. Through field research, the existing problems of the building are analyzed in detail in terms of building function, structure and appearance, and a detailed plan for functional upgrading, structural reinforcement and façade renovation is drawn up, taking into account the actual requirements and environmental status. In addition, solar photovoltaic technology is integrated into the renovation of the building’s pitched roof. Through modelling and analysis, the amount of solar energy captured by the photovoltaic roof is quantitatively simulated and the dynamic energy-saving potential of the renovation project under changing actual meteorological conditions is pre-evaluated. The preliminary results indicate that such green renovations can contribute to about 164,066 kWh annual solar energy collection and the self-use electricity from the PV roof accounts for 42–76% of total energy consumption, leading to about 60% building energy consumption conservation. The payback period of such a renovation program is assessed to be about 1.9 years, which is quite economically feasible considering the local energy tariff policy. This paper explores the feasibility and design direction of green and low-carbon renovation and upgrading of old buildings, which can provide a reference for the application of green and low-carbon renovation of local old buildings.

“…Most of them are organic composites produced by recycling and reusing waste and relying on synthetic technology. (2) From the point of view of the raw materials of green environmental protection materials, it principally applies for some materials, such as nontoxic harmless or relatively low waste emissions [4]. Toxic substances such as formaldehyde and benzene will not be involved in the production process of materials, which can effectively reduce the damage of architectural materials to residential health by this way.…”

Industry 4.0 is derived from the concept of German industry, and its essence is to use technology for efficient production. However, the evolution in wireless technologies has opened the door to a new class of plant automation architecture that offers adopters a significant strategic advantage. Under the historical background of advocating low-carbon production, energy conservation and environmental protection, and sustainable development in various fields, the awareness of ecological energy conservation and environmental protection has gradually become a mainstream ideology. This paper principally studies the application of energy conservation and environmental protection green decoration materials in public architectural engineering projects to show the advantages of energy conservation and environmental protection green decoration materials in architectural decoration construction and analyzes the future development direction of public architectural decoration in China. Therefore, it is of great significance to improve the public environment and develop new ways of housing renovation with sustainable development goals to create a sustainable Industry 4.0 combining environmental protection and sustainability.

“…Jianen Huang et al [7] established a thermal performance optimization model for building envelope structures using existing residential buildings as an example and determined that the energy-saving rate of insulation materials ranges from 0.53% to 73.59%. Xinxin Zhang et al [8] conducted a renovation of old city buildings in Beijing and calculated and analyzed the energy consumption of winter heating and domestic hot water supply before and after the renovation. The results showed that the insulation performance of building envelope structures was a key factor affecting the energy consumption of old city buildings, and the energy-saving rate of the renovated buildings could reach 65.53%.…”

In the cold regions of China, the existing rural houses are widely distributed and in large numbers. There are widespread problems such as low thermal performance of building envelopes, high building energy consumption, and poor indoor thermal environments. Reducing the energy consumption of building heating by reforming the envelope structure can reduce the environmental pollution caused by heating. In this paper, the existing rural houses in Tongchuan City, Shaanxi Province are taken as the research object, and EnergyPlus software is used to calculate building heating energy consumption, and the schemes are compared and selected via the entropy value method. Based on a comprehensive benefit evaluation, the best scheme for the renovation of building envelopes of rural houses in Tongchuan City is put forward. The research results show that the energy saving rate of buildings can reach more than 50% after renovation. In the evaluation of energy saving, incremental cost, return on investment, carbon emission reduction and unguaranteed hours, the weights are 0.1915, 0.2104, 0.2312, 1755, and 0.187, respectively. The best renovation scheme for rural housing is as follows: the thickness of the XPS board is 90 mm for exterior wall insulation; the thickness of the XPS board is 80 mm for roof insulation; the window-to-wall ratio of additional sunspace is 0.6; and the type of exterior windows is a broken-bridge hollow aluminum window of 6 + 12A + 6 (mm).
