Special Issue Information

Dear Colleagues,

The built environment, including buildings and infrastructure, significantly contributes to global carbon emissions. To achieve ambitious climate targets, it is essential to explore comprehensive carbon management strategies and decarbonization pathways within this sector. This Special Issue invites innovative research focusing on cutting-edge methods, technologies, and policies aimed at reducing carbon footprints, enhancing energy efficiency, and promoting sustainable development in buildings and infrastructure. Topics of interest include lifecycle carbon analysis, renewable integration, intelligent energy management systems, sustainable construction materials, and policy frameworks that drive effective decarbonization. Additionally, we encourage submissions that address emerging trends, such as digitalization, smart buildings, urban planning strategies, climate resilience, and circular economy practices. Research that evaluates the socio-economic impacts and barriers to implementation and case studies demonstrating successful carbon reduction initiatives are also highly valued. We welcome contributions from multidisciplinary perspectives, providing actionable insights to advance global sustainability efforts.

Low-Emissivity Cavity Treatment for Enhancing Thermal Performance of Existing Window Frames
by Maohua Xiong, Jihoon Kweon and Soobong Kim

Abstract
Windows contribute 40–50% of envelope heat loss despite occupying only 1/8–1/6 of the surface area. Conventional frame retrofits rely on geometry optimization or cavity insulation yet remain limited by cost and invasiveness. This study introduces electrochemical polishing to reduce cavity surface emissivity of [...] Read more.
Windows contribute 40–50% of envelope heat loss despite occupying only 1/8–1/6 of the surface area. Conventional frame retrofits rely on geometry optimization or cavity insulation yet remain limited by cost and invasiveness. This study introduces electrochemical polishing to reduce cavity surface emissivity of multi-cavity broken-bridge aluminum window frames to suppress radiative heat transfer, offering a non-invasive, low-cost retrofit strategy for existing building windows. Using a typical 75-series casement window, finite element analysis (MQMC) reveals that reducing cavity surface emissivity from 0.9 to 0.05 lowers frame U-values by 12.39–30.38% and whole-window U-values by 2.72–9.69%, with full-cavity treatment outperforming insulating-cavity-only by an average of 0.29 W/(m2·K). EnergyPlus simulations across multiple climate zones show 0.74–2.26% annual heating and cooling energy savings (with max reduction of 8.99 MJ/m2·yr) in severe cold and cold regions (e.g., Harbin, Beijing), but 1.25–3.04% penalties in mild and hot-summer zones due to impeded nighttime heat rejection. At an incremental cost of 62.5 CNY/window (6.6–7.4% increase), the static payback period is 4.1 years in Harbin. The approach mitigates thermal bridging more effectively than foam-filled frames in whole-window performance. This scalable, minimal-intervention technology aligns with low-carbon retrofit imperatives for existing aging windows, particularly in heating-dominated climates. Full article

To achieve a dynamic balance between economic development and ecological protection, it is necessary to analyze the enabling mechanism of new quality productive (NQP) on the green and low-carbon transformation of the construction industry. Based on the panel data of 107 cities in the Yangtze River Economic Belt (YERB) from 2011 to 2023, this study analyzes the spatiotemporal characteristics of carbon emissions in the construction industry (CECI), and explores the impact, mechanism, regional heterogeneity and spatial spillover effect of NQP on carbon emission intensity in the construction industry (CEICI). From 2011 to 2023, CECI increased in low amplitude but weakened the spatial concentration. The overall level of NQP in the YREB region shows a trend of first a slight decline and then a steady increase, and the development disparities among different regions have continued to widen. The NQP is significantly negatively correlated with the CEICI. The impact effect shows a gradient distribution pattern of “upstream > downstream > midstream”, and there is also a spatial spillover effect. Moreover, the mechanism analysis shows that the NQP can influence CEICI by the green technological innovation (GTI) and industrial structure upgrading (ISU). Moreover, the mediating effect of GTI (−0.4019) is greater than ISU (−0.1049). These results can help to formulate policies on NQP for reducing building emissions. Full article

Prefabrication in a controlled factory setting may improve the energy performance of modular buildings compared to traditional site-built facilities. However, few studies report empirical evidence to support this premise in full-scale operational buildings. Since energy efficiency standards in the United States are driven by building code, the compliance path chosen and field verification through site inspection, an investigation of how site-built and modular projects satisfy code requirements is critical to understanding long-term energy consumption. Therefore, this study investigated and compared Energy Code Compliance (ECC) among 55 commercial multifamily buildings (25 modular and 30 site-built) in four American Society of Heating, Refrigerating and Air-Conditioning Engineers climate zones (3B, 3C, 4A and 4C). For climate zone 3, ECC analyses indicated that modular slightly exceeded site-built construction. For zone 4, site-built construction slightly exceeded modular. Nearly all buildings met or exceeded the prescriptive energy code requirements for each climate zone regardless of whether a performance or trade-off compliance path was utilized. Field observations suggest that envelope construction quality in modular buildings could be higher. Results provide insights for researchers exploring energy use in buildings, as well as the basis for a nuanced understanding of normalized operational energy consumption in an ongoing longitudinal study of the same 55 multifamily buildings.
