About a year ago I was asked to speak at the University of Oregon’s annual H.O.P.E.S. conference and lead a workshop demonstrating the computational approach to design we promote on this blog and at the Yazdani Studio. The workshop focused on the optimization tools we have been piecing together using Grasshopper for Rhino and its many add ons. Today we’re going to share an updated version of the Gh definition used in the workshop. A video that breaks down the definition and various steps involved is also included below. The goal here is to share a general framework for creating optimization tools with Grasshopper. My hope is that the script below, along with breakdown video, might be a useful guide for anyone interested in developing their own optimizations or tailoring them to specific situations. In the example provided, the definition is used to optimize a building form to receive the minimum possible total solar radiation given only the geographical location, building area, and number of floors.

It’s been several years now since the Galapagos component was included in Grasshopper for Rhino. Back in 2011 Charles Aweida wrote a blog post that included a proof of concept in which he used this tool to optimize a simple multi-sided form to receive the lowest amount of heat energy from the sun. Since then, we’ve been trying to create optimization tools at the building scale that can inform our decision making process during design. The videos below are optimizations for heat gain and views on a site in Boston, MA. We are actively looking for ways to expand this list to include a wider range of project / site specific design drivers such as daylighting, structure, and wind.
