Special Issue Information

Dear Colleagues,

Excessive carbon emissions lead to global warming and extreme weather, threatening the safety of human beings. Meanwhile, the energy supply chain crisis is constantly challenging the lifeline of global economic sustainable development, especially after the COVID-19 pandemic. To this end, many countries, cities, and large international enterprises have made carbon neutrality commitments and taken action to fulfill the requirements of the Paris Climate Agreement and promote the transformation of their energy-consumption structure. The construction industry is an important creator of carbon emissions. Both the production of engineering materials and the consumption of fossil fuels can release massive amounts of carbon dioxide. It is essential to promote the green transformation of the traditional building materials industry, deepen and accelerate energy conservation and emission reduction, and help achieve carbon neutrality in the future. Green building and green construction are not only an environmental problem but also an opportunity for the construction industry. New challenges are present in the application and evaluation of carbon capture and storage in civil engineering, i.e., CO2 capture and adsorption in construction materials, CO2 curing technology, carbonation treatment, the analysis of carbon sink, and carbon capture and storage in civil construction. Innovative theories, insights, and data on low-carbon or carbon-negative theoretical and technological applications are thus highly anticipated by the whole world.

In light of these considerations, this Special Issue intends to provide researchers worldwide with a forum to share their research outcomes and report recent advancements in Advances in Low-Carbon Buildings. We hope this Special Issue will provide a timely overview of the recent case histories, theoretical advances, laboratory and field testing, and design methods. Original contributions containing fundamental and applied research, case studies, or the state of the art are encouraged for submission.

With the background of rural revitalization, the urgent demand for energy conservation and improved living quality arises alongside the issues of high energy consumption and low comfort in residential buildings. Located in a region with a hot summer and cold winter climate, Hanzhong faces significant energy consumption for heating and cooling throughout the year, considering both winter insulation and summer heat insulation. Based on the energy consumption simulation and analysis of folk dwellings in Hanzhong, this paper employs a single-objective optimization method to explore the optimization of building envelope structures, including the window-to-wall ratio, bay width, number of floors, orientation, and floor height. Additionally, it investigates building layout, spatial organization, regional design methods, and energy acquisition. Through energy consumption simulation and validation of thermal comfort evaluation index PMV-PPD, design strategies such as building scale, layout organization, indoor and outdoor buffer space design, and building material selection are proposed to effectively improve indoor thermal comfort during the winter and summer seasons. This research provides insights and references for the low-carbon design and optimization of residential buildings. Full article

Raised access floors are nowadays widely used in buildings. A novel raised access flooring product is developed by this research, with a set of sustainable features, including less environmental impact and high strength. Its floor panels are made of polyurethane (PU) reinforced with glass fibre, which is light-weight and fire-resistant, replacing the traditional floor panel materials, and the panels are supported by simplified steel stringers to reinforce the strength of the flooring product. Instead of the conventional sandwich design consisting of a core material encapsulated by outer layers, the new floor panel design adopts the reinforced PU as its sole material, which not only simplifies the structure but also reduces floor weight and costs. The sustainable advantage is further approved by the environmental life cycle assessments of the new raised flooring product in comparison to traditional ones made of cement and woodchips, with results showing that the new floor product’s total environmental impact is 52% less than cement floor and 47% less than woodchip board floor. Further, the finite element analysis (FEA) was carried out, and the experimental test was conducted to verify the FEA results, indicating that the new product’s strength is higher than the requirements of the raised access flooring product standards. There is no raised access flooring product made of PU reinforced with glass fibre available in the market, and, hence, the new product developed by this research is a novel contribution. Full article

Fluidic silty sand is often difficult to use directly in engineering construction because of its low strength and plasticity index. This study employed steel slag to replace part of the cement in silty sand stabilization to broaden the feasibility of resource recycling and to reduce the construction cost and carbon emissions in engineering practices. A series of indoor tests investigated the influences of the cement/steel slag ratio, initial water content, curing age, and temperature on the compressive strength of cement- and steel slag-stabilized fluidic silty sands (CSFSSs). Their stabilization mechanism was discussed via microstructural observation and spectral analysis. The results showed that the most economical cement/steel slag ratio could be 9:6, saving 40% of cement and not changing with the initial water content. The compressive strength of the CSFSSs decreased with the initial water content and increased rapidly and then slowly over the curing age. The curing temperature had a positive impact on their strength growth. The microstructure characteristics and spectral analysis showed that adding steel slag indeed affected the formation of gels in the cement-stabilized fluidic silty sands. This study could reference the application of CSFSSs in engineering practices. Full article
