Low-Energy Consumption Form of Polyline Plane Office Building

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.
