Published: Feb. 11, 2025

As the dual carbon goals are being approached, there has been an increase in number of energy-saving renovation projects for existing buildings. However, building also brings about environmental impacts and incremental costs, which need to be addressed urgently. This study proposes integrated artificial intelligence framework facilitate multi-criteria energy decision making by combining a surrogate-based machine learning (ML) model evolutionary generative algorithm efficiently accurately identify optimal strategies. To enhance robustness methodology, comparative analysis four different ML models—light gradient boosting (LightGBM), fast random forest (FRF), multivariate linear regression (MVLR), neural network (ANN)—was conducted, with LightGBM demonstrating best performance terms accuracy, adaptability, efficiency. Using heuristic optimization entropy-weighted method, achieved average savings 56.62%, reduction emissions 51.60%, 24.27% decrease life-cycle costs. Compared local ultra-low-energy standards, solutions resulted 2.60% 15.85% demonstrates potential surrogate models, generation, methods retrofitting optimizations, offering novel, efficient, adaptable approach researchers practitioners seeking balance consumption, emissions, costs projects.

Determination of Optimum Passive Design Parameters for Industrial Buildings in Different Climate Zones Using an Energy Performance Optimization Model Based on an Artificial Neural Network (ANN) and Particle Swarm Optimization (PSO)

Sustainability, Journal Year: 2025, Volume and Issue: 17(6), P. 2357 - 2357

Published: March 7, 2025

With a focus on reducing building energy consumption, approaches that simultaneously optimize multiple passive design parameters in industrial buildings have received limited attention. Most existing studies tend to examine geometry or individual under scenarios, underscoring the potential benefits of adopting comprehensive, multiparameter approach integrates climate-responsive and sustainable strategies. This study bridges gap by systematically optimizing key parameters—building geometry, orientation, window-to-wall ratio (WWR), glazing type—to minimize loads enhance sustainability across five distinct climate zones. Fifteen different geometries with equal floor areas volumes were analyzed, considering fifteen types orientations varying 30° increments. DesignBuilder simulations yielded 16,900 results, due inherent challenges directly within simulation environments, data restructured reveal underlying relationships. An Energy Performance Optimization Model, based Particle Swarm (PSO) algorithm integrated an Artificial Neural Network (ANN), was developed identify optimal solutions tailored specific climatic conditions. The optimization results successfully determined combinations WWR, type reduce heating cooling loads, thereby promoting efficiency carbon emissions buildings. offers practical solution set provides architects actionable recommendations during early phase, establishing machine learning-based framework for achieving sustainable, energy-efficient, designs.
