While I am not a big real estate person, I took an introductory class in real estate development this quarter and it really struck me how generative design could take the requirements and constraints for a building or set of buildings and turn them into a set of possible designs. Real estate development is all about bringing a piece of land to its highest and best use, which screams optimization.
I want to design a tool for real estate developers to better make early building form design decisions based on a set of requirements found in the due diligence process. This could be floor area ratio requirements, height limitations, or something about material. These things would be accounted for while optimizing for things that are indicative of building expenses and revenues such as volume and wall surface area of buildings. This tool would improve developers’ ability to generate specifications of building forms to give to designers. By automating calculations and exploring the set of options that are available to developers, the early design stage would be streamlined.
Inputs
The constant inputs would include:
- Site Area
- Floor Area Ratio
- Max Building Height
- Setbacks
- Floor to floor height
The variable inputs would include:
- Locations of the buildings
- Building Height as a percent of max
- Apportioned percent of allowed floor Area
Underlying logic of the model you’ll implement
These variables would be connected through node logic to find the actual building height and footprint for each building form and produce the solid in Dynamo. The gross allowable floor area will be apportioned to each building through waterfall logic where the first building claims floor area through a variable input percentage, the second building takes a percent of the remaining floor area based on a variable input percentage, and the rest of the floor area budget does to the third building. The logic would also include a penalty for building forms overlapping with each other or the setback line, which will be constrained in the generative study.
Outputs
The outputs of the study will be:
Measures of Profitability
- Total Project Building Volume
- Total Project Floor Area
Measures of Expense
- Total Wall Surface Area (Can be multiplied w/ developer’s criteria to find total heating/cooling expense)
