ARCH 655 Project2

Taichung Metropolitan Opera House

- Optimization of the building shape based on radiation analysis -

In Project 2, I utilized Ladybug and Galapagos, the former one is for radiation analysis and the latter one is for genetic algorithm. These tools optimize the building shape so that occupants can get maximum radiation. I simplified the building model and assumed that curvy walls consist of the whole building and the shape is covered with one big glass box.

Sun path

1) Find weather data URL from Ladybug epwmap and put it in "Panel" in Grasshopper

2) From the epw data, we can get the exact annual sun path on the site, Taichung, Taiwan

Optimization of the building shape

1) To optimize the shape of the curvy walls, I chose three layers of Voronoi curves and got two layers of lofted curvy walls. ( Please look over Project 1 page for the process of producing Voronoi curves and curvy walls )

2) Put the same weather data URL with sun path analysis in "Panel"

3) Select surrounding buildings and put them into "Brep" component

4) Connect "Merge Face" component containing lofted curvy walls to geometry input of "Radiation Analysis" component and show radiation result onto curvy walls

5) Select the total radiation number for Galapagos fitness input and maximize this value

6) Select two sliders for Galapagos genetic input; one is involved in a transfer of Voronoi points in the first layer and the other is involved in that of the third layer

( Each slider is ranging from -5 to 5 )
