折线型平面办公建筑的低能耗形态

Low-Energy Consumption Form of Polyline Plane Office Building

摘要:

针对折线型平面的办公建筑，选取其中最基本的“一折”平面作为研究对象，通过收集以杭州、上海为主的折线型建筑案例的数据，以面宽、进深和折角等基础参数作为生成平面形态的边界条件；借助Python工具进行数学建模，生成不同形式的“一折”平面建筑模型；利用基于EnergyPlus平台的Designbuilder能耗软件对各模型进行全年能耗动态模拟；通过斯皮尔曼系数法进行相关性分析，得到影响能耗最大的两个平面形态参数，面宽进深比M₁和斜进深M₂。研究表明，一折平面存在形态临界点，面宽进深比的临界点为7.6，斜进深的临界点为32 m。通过数据拟合得到形态参数M₁、M₂与总能耗E₁相互映射的变化趋势，即M₁?M₂?E₁的等高线图。

Abstract:

This paper selects the most basic “one-fold” plane as the research object for office buildings. It takes basic parameters such as width， depth， and angle as the boundary conditions to generate the plane shape by collecting the data of polyline cases mainly in Hangzhou and Shanghai. Using Python tools for mathematical modeling， it generates different forms of “one-fold” plane building models. Using the Designbuilder energy consumption software based on the EnergyPlus platform， it dynamically simulates the annual energy consumption of each model. Using the Spearman coefficient method for correlation analysis， it obtains two plane morphological parameters that have the greatest impact on energy consumption， the width-to-depth ratio M₁， and the oblique depth M₂. Finally， performing regression fitting and regression evaluation on the model data， it obtains the changing trend of the mutual mapping between the morphological parameters M₁， M₂ and the total energy consumption E₁， and draws the contour map of M₁-M₂-E₁ accordingly.
