Generate different building shapes based on floor area

Hi everyone,
In my study, a Revit model of a rectangular building is given, then I need to generate different shapes of the building before running energy simulations with HoneyBee. From the Revit model, I could manage to create the HB model for the Rectangular shape.
I would like to ask your advice on how to generate 3-4 building shapes with the same floor area, given an initial rectangular floor plan with a defined width and length. As you can see in the picture, shape 1 is the initial shape.


Since I am new to grasshopper, any suggestions is veery welcomed,

Best regards

Hello,
You are targeting multiple topics in one project. Although your main goal is very clear, the process is multi-step.

1- your first task is to use Evolutionary solver Like (Galapagos) with predefined inputs (length, width ,etc) and goal criteria (Like Floor Plan, Proportions, Recess Depths). This will generate a lot of options for you to test with Honeybee.

2- for each of the solutions above, use the builtin Honeybee tools to simulate daylight, energyplus or Openstudio Models. and report the outcome to the evolutionary solver mentioned in step 1 above.

This is the ideal workflow, just keep in mind, this is not realtime, not even close, expect your machine to work for days if not weeks depends on the complexity of your projects.
