Fall 2019




Perspective View of Model in Photoshop



·        Project Basic Information
         Architecture: Zaha Hadid Architects
         Location: Chaoyangmen, Beijing, China
         Project Type: Mixed-use commercial development
         Construction Year: 2009-2012
         Plot Area: 46,965 m2
         Built Up: 330000 m2
         Max Height: 67 m
         Total Floors: 18

In the project two, the model will be refined by applying python scripting and Graph mapper function. In this project, the challenging part is minimizing, the surface area with the fixed volume which is optimized.

·                   Project Outline
The project outline of SoHo Galaxy is described in this section. The modeling and analysisng processes can be divided into 5 sections as follow:
-          Generating Model by using Python Scripting for Grasshopper
-          Solar Analysis through Ladybug
 ( Sun Path Analysis, Radiation Analysis and Wind Analysis)
-          Optimization through Galapagos
 (Minimizing Surface Area with fixed Volume)



o   Modeling the Buildings
To start, Python Scripting for Grasshopper is used to create "For" loops and refined the base structure of the model.



Then the overall shape of the model is created by using Python Scripting and Graph Mapper method in Grasshopper.


o    Solar Analyzing through Ladybug
The Solar Analysis part are divided into three subsections, which are Sun Path Analysis, Radiation Analysis and Wind Analysis. We will run each analysis by clicking the toggle button. To do Sun Path Analysis, EPW file for Beijing, China is downloaded from Energy Plus website and imported to analysis.


Solar Path Analysis is calculated based on Defined Hour and Month.


o   Radiation Analysis

Radiation Analysis is done by Importing EPW file and Sky Matrix Data.


Total Radiation, Diffuse Radiation and Direct Radiation can be extracted from radiation analysis.



o   Wind Rose Analysis



o   Optimization through Galapagos
       In this part, minimizing the surface area with considering fixed volume is optimized by applying Galapagos tools. The Radius of Ellipse as imported and The Surface Area to Fix Volume Ratio  is determined as Fitness for Galapagos Analysis

                                                Arch 653-Final Project using Dynamo Plugin       Arch 653| Project 02: Mary Axe (The Gherkin  Neda Sadeghi Spring 2021 In Prject1, I created the solid mass and have  parametrically controlled the dimension of solid mass and number of grid of curtain panel. In this final project, I used Dynamo plugin in Revit to improve and update my modeling process using Dynamo features and capabilities. These improvement can be included as: 1) Controlling the curtain panel number of grid, grid rotation    as well as size of mass model; 2) Control the color of each element of curtain family type; 3) Solar Study in order to analyze the color changes of curtain panel adjusted to sun direction and angel; 4) Add color override view in order to map the different color in a picture to the façade from an image, and controlled by Dynamo; 1) Controlling the curtain panel number of grid, grid rotation  as well as size of mass model. To do so, I created the link be

Its architecture is a composition of five continuous, flowing volumes that are set apart, fused or linked by stretched bridges. These volumes adapt to each other in all directions, generating a panoramic architecture without corners or abrupt transitions that brea
