Integrating Machine Learning and Genetic Algorithms to Optimize Building Energy and Thermal Efficiency Under Historical and Future Climate Scenarios

Sustainability, Год журнала: 2024, Номер 16(21), С. 9324 - 9324

Опубликована: Окт. 27, 2024

As the global energy demand rises and climate change creates more challenges, optimizing performance of non-residential buildings becomes essential. Traditional simulation-based optimization methods often fall short due to computational inefficiency their time-consuming nature, limiting practical application. This study introduces a new framework that integrates Bayesian optimization, XGBoost algorithms, multi-objective genetic algorithms (GA) enhance building metrics—total (TE), indoor overheating degree (IOD), predicted percentage dissatisfied (PPD)—for historical (2020), mid-future (2050), future (2080) scenarios. The employs IOD as key indicator (KPI) optimize design operation. While traditional indices such mean vote (PMV) thermal sensation (TSV) are widely used, they fail capture individual comfort variations dynamic nature conditions. addresses these gaps by providing comprehensive objective measure discomfort, quantifying both frequency severity events. Alongside IOD, use intensity (EUI) index is used assess consumption per unit area, critical insights into efficiency. integration with EUI PPD enhances overall assessment performance, creating precise holistic framework. combination ensures efficiency, comfort, occupant well-being optimized in tandem. By addressing significant gap existing methodologies, current approach combines advanced techniques modern simulation tools EnergyPlus, resulting efficient accurate model performance. reduces time Utilizing SHAP (SHapley Additive Explanations) analysis, this research identified factors influence metrics. Specifically, window-to-wall ratio (WWR) impacts TE increasing through higher heat gain cooling demand. Outdoor temperature (Tout) has complex effect on depending seasonal conditions, while (Tin) minor impact TE. For PPD, Tout major negative factor, indicating improved natural ventilation can reduce whereas Tin larger open areas exacerbate it. Regarding WWR significantly affect internal gains, windows temperatures contributing increased reduced comfort. also positive its varying over time. demonstrates conditions evolve, effects become pronounced, highlighting need for effective management envelopes HVAC systems.

Assessing the Relationship between Land Surface Temperature and Composition Elements of Urban Green Spaces during Heat Waves Episodes in Mediterranean Cities

Forests, Год журнала: 2024, Номер 15(3), С. 463 - 463

Опубликована: Март 1, 2024

In the context of escalating global temperatures and intensified heat waves, Mediterranean region emerges as a noteworthy hotspot, experiencing surge in frequency intensity these extreme events. Nature-based solutions, particularly management urban green infrastructure (UGI) areas, have shown promising outcomes adapting areas to challenges posed by waves. The objective current study is twofold: firstly, identify compositional patterns strategically distributed small public spaces, demonstrating their enhanced capacity mitigate impact waves region; secondly, assess association, direction, explanatory strength relationship between composition elements UGI area typology, specifically focusing on variation land surface temperature (LST) values during wave episodes spanning from 2017 2023. methodology involved obtaining satellite images classifying based composition, orientation, typology. Ordinal multiple regressions were conducted analyze considered variables LST ranges that occurred findings indicate an increase across many emphasizing heightened thermal stress medium-sized compact city, Granada (in southeast Iberian Peninsula). Traditional squares, pocket parks gardens, pedestrian with trees impervious surfaces performed better reducing probability exceeding above 41 °C compared other vegetated patches mainly occupied herbaceous vegetation grass. concludes advocating for strategic incorporation vegetation, especially trees, along traditional squares featuring semipermeable pavement shrubbery, potential effective strategy enhancing resilience against Overall, this research enhances our understanding dynamics offers guidance bolstering spaces region.
