摘要:

建筑的自遮阳形状会大幅影响建筑接收的直射阳光量,除材料、窗墙比等其他主要影响变量外,还对建筑运行能耗有显著影响。深度学习有望通过高效预测建筑能耗性能为设计师和工程师提供辅助。本文评估了两种不同神经网络结构——全连接神经网络(Dense Neural Network, DNN)和卷积神经网络(Convolutional Neural Network, CNN)——在基于建筑形状预测建筑运行能耗方面的适用性。两种神经网络的对比结果显示,DNN模型在性能、简洁性和计算时间上均优于CNN模型。不过,基于图像的CNN具备可利用建筑图形的优势,有助于设计沟通。

英文摘要:

A building self-shading shape impacts substantially on the amount of direct sunlight received by the building and contributes significantly to building operational energy use, in addition to other major contributing variables, such as materials and window-to-wall ratios. Deep Learning has the potential to assist designers and engineers by efficiently predicting building energy performance. This paper assesses the applicability of two different neural networks structures, Dense Neural Network (DNN) and Convolutional Neural Network (CNN), for predicting building operational energy use with respect to building shape. The comparison between the two neural networks shows that the DNN model surpasses the CNN model in performance, simplicity, and computation time. However, image-based CNN has the benefit of utilizing architectural graphics that facilitates design communication.
