Urban heat islands (UHIs) increase urban warming and reduce outdoor thermal comfort due to changing surface characteristics climate change. This study investigates the role of green walls (GWs) in mitigating UHI, improving comfort, reducing carbon emissions under current future (2050) scenarios. Focusing on Via della Consolata, Turin, Italy, combines remote sensing for UHI detection numerical simulations analysis during seasonal extremes. The results show that GWs slightly air temperatures, with a maximum decrease 1.6 °C winter (2050), have cooling effects mean radiant temperature (up 2.27 °C) peak summer solar radiation. also improve Universal Thermal Climate Index by 0.55 2050. energy shows emission intensity is reduced 31%, despite heating demand increasing 45%. highlights potential adaptation, particularly dense environments low sky view factors. Seasonal optimization crucial balance demand. As cities face rising temperatures waves, integration offers sustainable strategy microclimate, emissions, mitigate UHI.

Improving thermal comfort often impacts daylight, creating trade-offs that remain underexplored, particularly in tropical dwellings. Overheating metrics-essential for assessing conditions warm regions-are entirely absent from daylight performance analysis. Response Surface Methodology (RSM) and desirability functions were employed to optimize the of a typical low-rise housing typology. Specifically, this approach simultaneously optimized Indoor Hours (IOH) Useful Daylight Illuminance (UDI) metrics through an Overall Desirability (D). Each response required only 138 simulation runs (~ 30 h: 276 runs) determine optimal values passive strategies: window-to-wall ratio (WWR) roof overhang depth across four orientations (eight factors). Initial screening based on [Formula: see text] fractional factorial design, identified key factors using stepwise Lasso regression, narrowed down three: south west, WWR south. Then, RSM optimization yielded solution (west/south overhang: 3.78 m, west WWR: 3.76%, 29.3%) with D 0.625 (IOH: 8.33%, UDI: 79.67%). Finally, robustness analysis 1,000 bootstrap replications provided 95% confidence intervals values. This study balances few experiments computationally-efficient multiobjective approach.

Climate change and improving building energy performance are significant contemporary concerns. Conversely, climate-adaptive envelopes (CABEs) offer promising solutions to enhance structural amidst fluctuating environmental conditions. Despite extensive research, few studies have compared the general movement strategies of climate-specific CABEs. Thus, this study examines common methods—Changing Opening Percentage (COP), Changing Shading Angle (CSA), Fraction Axis (CFA), Pattern Geometry (CPG)—in terms their daylight in Mashhad, Iran's cold semi-arid climate (BSk). Simulation using LBT 1.6.1, a Grasshopper plugin Rhinoceros, assessed Energy Usage Intensity (EUI), Spatial Daylight Autonomy (sDA), Annual Sun Exposure (ASE). The results highlight COP-CSA integrated model as optimal, achieving 4-8% reduction usage intensity, thus demonstrating its efficacy amid change.

As smart schools increasingly rely on technology, achieving energy efficiency becomes crucial for cost reduction and sustainability. This study investigates strategies in schools, focusing the integration of renewable technologies. A quantitative approach using numerical simulations literature reviews establishes benchmarks energy-efficient schools. The Design Builder software is employed to evaluate system performance, with validation achieved through analysis System Advisor Model software. modeled school building consumes 75,385.63 kWh annually, based weather conditions specific location. Further studies indicate that integrating photovoltaics hot water collectors can generate approximately 86,635 annually. not only offsets consumption but also produces an excess 11,249 kWh, which be transferred back grid additional revenue. Validation SAM demonstrated a minimal difference (3.2%) annual outputs, confirming accuracy model. findings suggest significantly contribute net-zero buildings. Additionally, focus rooftop installations promotes sustainability by minimizing land use.
