ARCH 653 Project 2

Parametric Modeling Using Dynamo and Revit

Introduction

The aim of this project is to develop a method to control the color of the curtain panels in the building modeled previously in Project 1

In addition, the shading system will be designed for tracking the sun path. Thus ‘solar angle’ is necessary.

1 Random Color Curtain Panels

The building has more than 4500 windows that have different colors following the image. In order to achieve this goal I use Dynamo.

Firstly, I make six different materials and distribute them among the curtain panel system in a random way  

Secondly, I use an Excel sheet to alternate the panels with six colors and materials. I use 0, 1, 2, 3, 4 and 5 to design the curtain panels based on the image.

Thirdly, I import the list into dynamo and I “If” note to help me change the elevation of this building based on time.

Finally, I use Python note to assign each material to the different panel with the corresponding index. The result is changing the color of the widows  all at once with the flexibility of adding more materials or changing the colors distribution.

2 Shading System Controlled by Sun Path 

The second objective is to use the sun movement to control the rotation angle of the shading devices.

Firstly, I use the “Sun Settings. Current” and “Sun Settings. Sun Direction” notes to get the position of the sun. Then I use “Vector” and “Formula” (sin A=x/z) note to get the angle.

Secondly, I use the “Element. Set Parameter By Name” to control the rotation angle based on the sun path.

ARCH 653 Project 1

Parametric Modeling Practicing In Revit--Torre Agbar

For project one, I choose the Torre Agbar which is a landmark in Barcelona, Spain and it was completed in 2005. This tower was designed by Jean Nouvel. The height of Torre Agbar is 473 feet with 31 floors above the ground

Its façade is made of 4500 windows, and its skin colors are 40 variations of red and blue. 

Additionally, the outside skin of this tower is made of 59000 glass louvers which can be placed at different angles.

    

Before modeling, I analyzed the floor plan and sections from the internet. The shape of floor plans are  regular ellipses, however after analyzed the sections I found the size of ellipses become smaller from 15^th floor. And the top of the tower is a dome which base shape is ellipse.

Now I start modeling the tower in Rrvit.

First, because the façade of building keeps going straight before reaching the 15^th floor, I choose 1^st 7^th 15^th 25^th 31^st floors as the typical floors to create mass model. I create an ellipse mass for the floor and add parameters to control length of two basic ellipse axis. And I will add formulas to control the size of smaller ellipse floors: basic axis * factor. Thus the form of this tower can be created as a bullet.

Second, I will work on the first skin panel and the second skin panel, and add the parameter to control these panels. 

In the mass model, I divided the surface into rectangular unit. After that I can add the panels on my tower skin.  

After finish the mass model, I also create 31th floor which has celling, floor, doors, windows and furniture and I render it.
