Harnessing Artificial Intelligence to improve building performance and energy use: innovations, challenges, and future perspectives
Buildings consume about 36% of global energy and contribute nearly 40% of CO? emissions, making them central to the challenges of energy and climate. Artificial intelligence (AI) offers transformative pathways to improve forecast accuracy, optimize consumption, and support low carbon transitions. Oriented by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, this review systematically screened the literature from 2020 to July 2025, with selective inclusion of previous foundational studies. In total, 268 publications were reviewed and 70 analyzed in depth. The synthesis covers three domains: (i) energy forecasting, with machine learning (ML) and deep learning (DL) improving demand and renewable generation prediction; (ii) optimization, with AI improving Heating, Ventilation, and Air Conditioning (HVAC) control, renewable scheduling, storage management, and smart grid operations; and (iii) energy efficiency, with AI-Internet of Things (IoT) frameworks enabling predictive control, fault detection, and Net Zero Energy Building (NZEB) strategies. Reported impacts include energy savings for HVAC of up to 37%, solar scheduling that reduces costs by 35%, and AI - IoT integration that reduces emissions by 21%. Publication trends show rapid growth since 2020, reflecting accelerated technological progress. The remaining challenges include data fragmentation, interoperability, high computational demand, and cybersecurity risks. In general, the findings highlight AI as a key enabler of resilient, efficient and climate-adaptive building energy systems.

AI in Energy Forecasting
Machine Learning (ML) and Deep Learning (DL) significantly improve demand and renewable generation prediction, leading to better grid reliability and planning. Accurate forecasting is critical for minimizing inefficiencies and enabling proactive energy management strategies. Data-driven approaches, particularly ANNs and advanced DL architectures, have demonstrated strong predictive capabilities by capturing complex and non-linear energy consumption patterns.
AI in Building Optimization
AI improves Heating, Ventilation, and Air Conditioning (HVAC) control, renewable scheduling, storage management, and smart grid operations. RL offers substantial promise for adaptive real-time control of energy systems under dynamically changing occupancy and climatic conditions. Hybrid models and IoT-enabled control further enhance optimization strategies.
AI for Energy Efficiency
AI-Internet of Things (IoT) frameworks enable predictive control, fault detection, and Net Zero Energy Building (NZEB) strategies. This convergence leads to measurable reductions in GHG emissions and improved building sustainability. Green AI emphasizes energy-efficient algorithms and sustainable digital technologies.
