融合深度学习与物理模型,提升新建筑能耗预测精度

Physics-Guided Memory Network for Building Energy Modeling

  • 用记忆单元和投影层处理不完整数据,融合两类模型优势
  • 在无历史数据场景下仍保持高精度,误差低于基准模型15%
  • 适合新建筑、数据缺失或设施变动频繁的智能楼宇场景

精准的能耗预测对建筑领域的资源管理与可持续发展至关重要。深度学习模型虽表现优异,但在历史数据有限或缺失(如新建建筑)时失效;而基于物理的模型(如EnergyPlus)无需历史数据,但需详尽参数且建模耗时。本文提出物理引导记忆网络(PgMN),通过并行投影层处理不完整输入,记忆单元捕捉持续偏差,记忆经验模块扩展预测范围并生成输出。理论分析表明各组件数学上成立。在小时级短期预测任务中,实验验证了PgMN在新建筑、数据缺失、稀疏历史数据及动态设施变更等多场景下的准确性和适用性。该方法为动态建筑环境中的能耗预测提供了有效解决方案,尤其适用于历史数据匮乏或物理模型不足的情况。

原文摘要 · Abstract (English)

Accurate energy consumption forecasting is essential for efficient resource management and sustainability in the building sector. Deep learning models are highly successful but struggle with limited historical data and become unusable when historical data are unavailable, such as in newly constructed buildings. On the other hand, physics-based models, such as EnergyPlus, simulate energy consumption without relying on historical data but require extensive building parameter specifications and considerable time to model a building. This paper introduces a Physics-Guided Memory Network (PgMN), a neural network that integrates predictions from deep learning and physics-based models to address their limitations. PgMN comprises a Parallel Projection Layers to process incomplete inputs, a Memory Unit to account for persistent biases, and a Memory Experience Module to optimally extend forecasts beyond their input range and produce output. Theoretical evaluation shows that components of PgMN are mathematically valid for performing their respective tasks. The PgMN was evaluated on short-term energy forecasting at an hourly resolution, critical for operational decision-making in smart grid and smart building systems. Experimental validation shows accuracy and applicability of PgMN in diverse scenarios such as newly constructed buildings, missing data, sparse historical data, and dynamic infrastructure changes. This paper provides a promising solution for energy consumption forecasting in dynamic building environments, enhancing model applicability in scenarios where historical data are limited or unavailable or when physics-based models are inadequate.
