Buildings account for 39% of global carbon emissions, making the construction sector a pivotal contributor to climate change. In ecologically fragile plateau regions, tension between urban development and environmental sustainability poses significant challenge. This study examines spatiotemporal characteristics influencing mechanisms building emissions (BCEs) in cities using an empirical analysis 13-year panel data (2010–2022) from two municipalities six prefectures Qinghai Province, China. By employing eXtreme Gradient Boosting (XGBoost) model, we comprehensively assess drivers across four dimensions: socioeconomic structure, demographic factors, expansion patterns, climatic topographic attributes. Key findings include: (1) The XGBoost model exhibits robust predictive performance (R2 > 0.9, MSE < 0.1, RMSE 0.3), validating its effectiveness systems. (2) Socioeconomic structure significantly positively influence with GDP, per capita built-up areas being particularly influential. (3) interaction terrain increases buildings. (4) While is common factor affecting BCEs different types buildings, other such as population density, housing area, shape index, exhibit variability. These insights inform policy recommendations cross-regional flow balancing adaptive low-carbon planning strategies tailored ecosystems.

The incorporation of sustainable construction is essential for minimizing the environmental footprint cementitious composites. This research examines mechanical behavior and microstructural features alternative mortars in which pumice acts as a partial cement replacement. By applying Taguchi methodology, nine mortar mix variations were assessed at different replacement rates (15%, 25%, 50%), their strength was compared against control mixture without substitution. Additionally, an X-ray diffraction (XRD) analysis identified mineral components to evaluate performance durability. Based on statistical variance (ANOVA), with up 25% substitution are suggested they attain values comparable those mixture. study contributes advancement environmentally materials provides valuable insights into viability using infrastructure developments.

As societies are shifting toward carbon neutral environments, they beginning to account for their emissions. One of the primary contributors greenhouse gas emissions and global warming is building industry; therefore, Life Cycle Assessment (LCA) one instruments that allows an assessment energy energy-related environmental impacts buildings from cradle grave, according ISO 14040. In this context, aim research study assess dioxide (LC ) over a 50-year-lifespan zero-carbon solar-powered earth-based building, built with carbon-free adobe bricks, in hot semi-arid climate Morocco. While on equivalent () across life cycle crucial determine energy-intensive stages, looks into tendencies arising during cradle-to-gate embodied (A1-3) operational phases (B6) Zero Carbon Building (ZCB) case study, which should be offset by order abide ZCB definition.

The Belt and Road Initiative (BRI) stands as the most ambitious infrastructure project in history, marked by its scale of investment, extensive geographical reach across continents countries, a diverse array projects from roads to digital networks. While BRI's environmental sustainability has raised concerns, impacts construction materials used these have been overlooked, especially developing countries. Here, we map account for embodied BRI integrating, first time, official governmental reports, information, material flow analysis. We pinpoint analyze stocks each individual types, regions, sectors.

Building energy conservation and emission reduction are crucial in addressing global climate change. High-performance insulated building envelopes can significantly reduce consumption over a building’s lifecycle. However, few studies have systematically analyzed carbon potential through life cycle assessment (LCA), incorporating case regional differences. To address this, this study establishes an LCA calculation model using Information Modeling (BIM) technology the coefficient method. We examined four residential buildings China’s cold regions hot summer–cold winter regions, utilizing prefabricated concrete sandwich insulation exterior walls (PCSB) autoclaved aerated block self-insulating (AACB). Results indicate that emissions during operational phase account for 75% of total lifecycle emissions, with heating, ventilation, air conditioning systems contributing 50%. Compared to AACB, PCSB reduces by 18.54% 20.02% regions. The findings demonstrate offers significant energy-saving emission-reduction benefits construction operation phases. it exhibits higher materialization demolition This provides practical framework insights into reducing thereby guiding sustainable design.
