“…If the dominating factor is the emission factor, increasing the ash or GGBS proportion in the binder as well as lowering the water:binder ratio increases utility. Similar impacts were reported in [15,[26][27][28], pointing toward the robustness of the desirability function.…”

Abstract:The balance of carbon dioxide emissions and other greenhouse gases in the life cycle of concrete is one of the important elements affecting the sustainable development of concrete technology. Modifications in the composition in the aim of minimization of so-called "carbon footprint" of concrete also affect the majority of its technical features, including primarily the mechanical properties and durability. The article presents a desirability function that would allow us to estimate the combined effect of the modification in terms of both CO 2 emissions and some of the technical features of the concrete. As criterial features equivalent CO 2 emission, compressive strength and susceptibility/resistance to concrete carbonation are selected. Selected features should be considered as an example for the presentation of the proposed methodology and represent the three pillars of concrete desirability in terms of sustainable development, i.e., the constructional usefulness, durability, and environmental performance.

“…To achieve the low carbon targets, this study employed the LCBA-Neuma system, a local carbon survey software developed by the Low Carbon Building Alliance (LCBA) and the Faculty of Architecture at National Cheng Kung University (NCKU). This evaluation method considers both the Building Carbon Footprint and the Total Carbon Footprint (TCF) [7] and using the LCBA-Neuma system, the carbon footprints of the various phases of the building life cycle (LC) during renovation were recorded to understand how its carbon footprint evolved [8].…”

Military government was lifted from Kinmen in 1992. The opening-up of cross-strait relations transformed the island into a tourist destination. This transformation led to electricity and water shortages in Kinmen. With the reduction in the number of troops, military facilities fell into disuse and are now being released for local government use. The aim of this project was to monitor the carbon footprint of a reused military facility during renovation of the facility. The LCBA-Neuma system, a local carbon survey software developed by the Low Carbon Building Alliance (LCBA) and National Cheng Kung University in Taiwan, was used in this project. The system analyzes the carbon footprint of the various phases of the building life cycle (LC) during renovation and carbon compensation strategies were employed to achieve the low carbon target. This project has pioneered the transformation of a disused military facility using this approach. The carbon footprint of energy uses during post-construction operation (CFeu) accounted for the majority of carbon emissions among all stages, at 1,088,632.19 kgCO2e/60y, while the carbon footprint of the new building materials (CFm) was the second highest, at 214,983.66 kgCO2e/60y. Installation of a solar cell system of 25.2 kWp on the rooftop as a carbon offset measure compensated for an estimated 66.1% of the total life-cycle carbon emissions. The findings of this study show that the process of reusing old military facilities can achieve the ultimate goal of zero carbon construction and sustainable development.

Abstract:The concept of sustainability has been expanding to all areas of economic activity, including construction engineering. Construction engineering is a complex discipline that involves designing, planning, constructing and managing infrastructures. In this Special Issue, 27 selected and peer-reviewed papers contribute to sustainable construction by offering technological, economic, social and environmental benefits through a variety of methodologies and tools, including fundamental decision-making models and methods as well as advanced multi-criteria decision-making (MCDM) methods and techniques. The papers are mainly concentrated in five areas: Sustainable architecture; construction/reconstruction technology and sustainable construction materials; construction economics, including investments, supply, contracting and costs calculation; infrastructure planning and assessment; project risk perception, analysis and assessment, with an emphasis on sustainability.
