Step 1 - Generative Design Framework
Step 2 - Generative Design Study
I chose Design Decision 1 - Building Sustainability Design. I used the Generative Design tool to generate design options by the inputs (height and width), and analyzed the outputs to identify designs that provide an optimal balance between performance metrics. I’ll explain its Design Variables, Evaluators and Most Important Tradeoffs to Consider as below:
- Design Variables
- Building Height (m) - Varies from 10m to 500m with a step of 10m
- Building Width (m) - Varies from 10m to 500m with a step of 10m
- Evaluators
- Material Cost (USD) – calculated as (Wall Surface Area × Construction Cost per m² of Wall) + (Roof Surface Area × Construction Cost per m² of Roof)
- Energy Cost (USD/year) – calculated as Wall Surface Area × Energy Cost per m² of Wall
- Solar Value (kWh/year) – calculated as Roof Surface Area × Solar Value per m² of Roof
- Embodied Carbon (kg CO₂e) – calculated as Total Surface Area × Embodied Carbon Factor
- Most Important Tradeoffs to Consider
- Embodied Carbon vs. Energy Cost (to compare environmental impact of materials vs. long-term operational cost)
- Embodied Carbon vs. Material Cost (to assess sustainability without overspending)
- Material Cost vs. Energy Cost (to understand investment efficiency in performance improvements)
- Material Cost vs. Solar Value (to evaluate cost implications of maximizing solar exposure)
In addition, I generated alternative building forms and evaluate their performance and cost from a sustainability perspective. In the "User Settings" section, a set of input parameters can be changed by users. I set up these parameters as: a building volume of 300,000 m³, wall construction cost of 40 USD/m², wall energy cost of 80 USD/m², roof construction cost of 70 USD/m², solar value of the roof at 150 kWh/m², and an embodied carbon factor of 120 kg CO₂e/m². These parameters serve as essential inputs for calculating material costs, operational energy expenses, solar energy potential, and total embodied carbon for each design alternative.
