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.
