Special Issue Information

Dear Colleagues,

We are pleased to inform you that we have launched a new Special Issue of Buildings entitled "Sustainable and Low-Carbon Building." This Special Issue aims to reveal the latest studies on the education, design, and practice of sustainable and low-carbon building technology.

Sustainable technology development is of great significance for the maintenance of the Earth’s ecological environment. In order to ensure the low-carbon operation of buildings, engineers attempt to make progress in various aspects of their field, such as education, design and practice. By educating designers and builders, the waste of resources caused by human errors and omissions will be minimized. Through the optimization of building design and practice (e.g., BIM technology), resources can be utilized fully.

This Special Issue will publish high-quality, original research papers in the overlapping fields of:

  • Carbon emission management of infrastructure in the whole process;
  • Construction technology and the management of prefabricated buildings;
  • BIM technology and practice;
  • Sustainable design technology for buildings;
  • Repair and protection of traditional and ancient buildings;
  • Educational innovation in sustainable building design;
  • Education of low-carbon technicians.

Zn is a toxic heavy metal that seriously endangers human health and ecological stability. For a long time, traditional remediation techniques have been used to remediate Zn-contaminated soil prone to other problems such as secondary contamination. In recent years, due to the great danger posed by Zn pollution, there has been an increasing interest in applying eco-friendly and sustainable methods to remediate Zn-contaminated soil. Therefore, in this study, microbially induced calcium carbonate precipitation (MICP) technology was used to bioremediate zinc ions by transforming ionic heavy metals into insoluble solid-phase minerals. Through the unconfined compressive strength (UCS) test, direct shear (DS) test, and penetration test (PT), the results showed that the unconfined compressive strength of the treated specimens increased by 187.2~550.5%, the cohesion increased significantly compared with the internal friction angle of specimens, and the permeability coefficient can be reduced by at least one order of magnitude. During the treatment of Zn pollutants, the mobility of heavy metal zinc ions was significantly reduced, the percentage of exchangeable state Zn content was significantly reduced, and the leaching concentration of zinc ions in Zn-contaminated soil was reduced to about 20 mg/L, which was significantly lower than the limit in the standard (100 mg/L). These results were further confirmed by scanning electron microscope (SEM) and X-ray diffraction (XRD) analyses, which indicated coprecipitation of calcium carbonate (CaCO3) and ZnCO3. The microbial solidification/stabilization of Zn-contaminated soil was most effective when the curing age of 28 d, the cementation solution concentration of 1 mol/L, and the cementation solution ratio of 1:2. Therefore, the bio-immobilization of zinc ions by MICP has the potential for application as a low-cost and eco-friendly method for heavy metal remediation. Full article

Sustainable manufacturing is essential for boosting resource allocation efficiency, as well as sustainable economic development, while the construction industry is one of the main sectors affecting it. However, the complexity of multidisciplinary integration of sustainable manufacturing makes it challenging to fully integrate into architectural design teaching. By incorporating architectural design competitions in architectural design teaching, we can encourage students to systematically reflect on the role of elements beyond traditional architectural design during the architectural design process to help them gain a more comprehensive understanding of sustainable manufacturing. The research results were obtained with a combination of both qualitative and quantitative analysis. We analyzed the survey data through grounded theory and presented the results graphically, which include a framework for promoting the learning of sustainable manufacturing through architectural design competitions in teaching architectural design. In order to gain an in-depth and comprehensive understanding of the teaching effect and to ensure the reliability and accuracy of the results, in addition to qualitative analysis, we also adopted statistical analysis to clarify whether the new teaching method is really effective. In evaluating whether there was a statistically significant difference in the understanding of sustainable manufacturing between students who participated in architectural design competitions and those who did not, according to the established teaching objectives, we found that a statistically significant difference did exist in the results, and further analyzed other contributing factors through regression analysis. Our research shows that introducing architectural design competitions into architectural design teaching is a feasible way to promote students’ understanding of sustainable manufacturing. In architectural design competitions, sustainable-manufacturing-related elements, such as resources and economy, were taken into consideration in line with various design elements, such as site, environment, ecology, and energy consumption, which were integrated into students’ design process of thinking, drawing, modeling, and presenting. In this way, students will have a clearer understanding of approaches to achieve sustainable manufacturing through architectural design. This research helps tap into the value and potential of architectural design competitions in delivering sustainable manufacturing during architecture education and can offer references for college teachers to conduct sustainability education.

Double liquid grouting materials (DLGMs) are composed of slurry A and slurry B. In response to the need for sustainable development, there is currently a focus on improving the utilization rate of resources. In this paper, industrial solid waste fly ash, slag, and ordinary Portland cement were used to prepare slurry A, while sodium silicate was used as slurry B. Slurry C was made by adding slurry B to slurry A. The mix design parameters of the DLGMs, with large amounts of fly ash, were optimized based on the response surface method. The results showed that the relative content of cement and the reactivity and morphological effect of supplementary cementitious materials (fly ash and slag) were the main factors affecting the operable time, viscosity, and stability of slurry A. The relative content of cement and the sodium silicate modulus were the main factors affecting the operable time of the DLGMs. Compared to the C30F70S0-Z3.3 group (where C, F, S, and Z represented cement, fly ash, slag, and sodium silicate modulus, respectively), the operable time of the C0F70S30-Z3.3 group increased by approximately 36 min. As the sodium silicate modulus was lowered to 2.3, the operable time of the C0F70S30-Z2.3 group increased by about 32 min compared to that of the C30F70S0-Z2.3 group. The established model and response surface can well reflect the influence of multiple factors on the properties of the DLGMs. When the mass ratio of cement/fly ash/slag in slurry A was 7.5%: 70%: 22.5%, and the sodium silicate modulus and content of slurry B were 2.8 and 10%, respectively, the 28-day compressive strength of the DLGMs can reach up to 11.3 MPa. The content of fly ash was the most significant factor affecting the 28-day compressive strength of the DLGMs, followed by the sodium silicate content. The least influential factor was the sodium silicate modulus. The XRD and SEM results showed that a large amount of Ca2+ produced by cement hydration can quickly react with [SiO4]4- in sodium silicate to form C-S-H gel. Moreover, it also promoted the hydration of C3S and C2S in grouting to produce more C-S-H gel, which was conducive to the alkali activation of slag and fly ash, resulting in a denser microstructure and hence, yielded obvious increases in the compressive strengths of the DLGMs. Full article

In terms of the failure of giving considerations to both aesthetic ornamental and low-carbon function for the current disaster prevention and mitigation engineering. This study proposes the debris-disaster prevention baffles applicable to natural scenic areas which designed based on mangroves properties, to solve this problem by adopting bionic design method. The research methodology is as follows: (1) To propose a Six Elements and Ten Steps Design Method for extracting the critical bionic elements of mangrove plants that contributes to the prevention of winds and waves. (2) To construct a decision objective model based on the Analytic Hierarchy Process method (AHP). Prioritize the critical bionic design elements and build a geometric structure model. (3) To compare the disaster mitigation performance through numerical simulations, and thus select an optimal one for further studies. (4) To design the final disaster prevention product based on the above theoretical guidance, low-carbon concept, efficient protection orientation, and environment-friendly principles. This study indicates that the use of bionic design satisfies aesthetic ornamental, and low-carbon demands. The appliance of AHP avoids subjective one-sidedness in design process when considering the priority of bionic elements. The numerical simulation experiments adopted in this study aim to compare the blocking effect of different baffle models and achieve the optimization the performance in disaster prevention of traditional baffle groups. In this study, the bionic product design methodology is adopted for baffle design to solve existing aesthetic and environmental problems. The particle accumulation mass after the new baffles can be effectively reduced by 2–3 times compared to the traditional baffles. Furthermore, the new baffle is more aesthetically pleasing than the traditional ones. Full article
