Step 1 - Generative Design Framework

A very brief description of the design decisions from Step 1 following the Generative Design Framework.

These are the valuables and outputs I chose.

• Design Decision 1: Construction Planning
• Design Variables
• Variables 1 .. Level Height
• Evaluators
• Evaluators 1 .. Net Costs
• Most Important Tradeoffs to Consider
• Tradeoffs 1 .. The higher the level height, the lower the net costs.
• Design Decision 2 Structural Design
• Design Variables
• Variables 1 .. Building Length
• Evaluators
• Evaluators 1 .. Gross Volumes
• Most Important Tradeoffs to Consider
• Tradeoffs 1 .. The higher the building length, the higher the gross volumes.
• Design Decision 3 Sustainability
• Design Variables
• Variables 1 .. Building Depth
• Evaluators
• Evaluators 1 .. PV Earnings
• Most Important Tradeoffs to Consider
• Tradeoffs 1 .. The higher the building depth, the higher the PV earnings.
• Design Decision 4 Architectural Design
• Design Variables
• Variables 1 .. Panels Widths
• Evaluators
• Evaluators 1 .. Gross Window Areas
• Most Important Tradeoffs to Consider
• Tradeoffs 1 .. The higher the panel widths, the higher the gross window areas.

### Step 2 - Generative Design Study

• A more detailed description of the design decision from Step 2 that you decided to run a Generative Design Study with.
• Use the Generative Design Framework structure to explain how you’ve set up your Generative Design Study to keep it consistent.

I created a tall building with a regular rectangular shape. The building has window panels on its facades on each floor. Below are the variables and outputs. There are more than four, but I only used four combination to compare.

### Step 3 - Generative Design Study Results

• The screenshot of the Scatterplot or Parallel Coordinates Graph illustrating the tradeoff that you chose to model and study.
• Provide a brief explanation of what’s being shown in the Scatterplot or Parallel Coordinates Graph and how the tradeoff being illustrated would impact the design decision. What would you do with this information?

I expected all results to have a linear relationship. However, gross volumes and building length are positive linear relationships, and gross window areas and panel widths are positive linear relationships. For PV earnings and building depth, I expected positive linear relationships because there are more surface areas for PV panels, but there aren’t. For net cost and level height, I expect a negative linear relationship because higher height for each level means fewer levels and will result in lower construction costs, but there isn’t any relationship either.
