Designing High-Rise Structures Parametrically using Dynamo BIM
Introduction
By balancing height, floor type, and twisted angles, this research investigates how to maximize high-rise buildings’ structural and energy efficiency. We assess several design criteria in search of the ideal structure using Dynamo BIM.
Methods
Making models using Dynamo BIM
We created adaptable building models by using parametric inputs:
10, 20, and 35 stories in elevation
Types of floors: composite, concrete, and wood
Angles of Twisting: 0°, 30°, 60°
Study of Structure and Energy
Material efficiency and load-bearing capacity were evaluated for structural efficiency.
Energy Simulations: Analyzed ventilation effects, energy consumption, and temperature characteristics.
Structural & Energy Analysis
– Structural Efficiency: Assessed load-bearing capacity and material efficiency.
– Energy Simulations: Evaluated thermal properties, energy use, and ventilation effects.
Results
Structural Efficiency
| Design | Stories | Material | Load-Bearing | Efficiency | Twist |
| Option 1 | 10 | Concrete | High | 1.25 kg/load | 0° |
| Option 2 | 20 | Composite | Very High | 1.15 kg/load | 30° |
| Option 3 | 35 | Timber | Moderate | 1.10 kg/load | 60° |
– Option 2 (20 stories, 30° twist): Best structural performance with balanced material use.
– Option 1 (10 stories, concrete): Strongest but material-intensive.
– Option 3 (35 stories, timber): Lightweight but structurally weaker at higher heights.
Energy Efficiency
| Design | Material | Thermal Mass | Energy Use | Insulation | Twist |
| Option 1 | Concrete | 350 MJ/m² | 120 kWh/m² | High | 0° |
| Option 2 | Composite | 250 MJ/m² | 130 kWh/m² | Moderate | 30° |
| Option 3 | Timber | 150 MJ/m² | 140 kWh/m² | Low | 60° |
– Option 1 (Concrete, 0° twist): Best energy efficiency due to high thermal mass.
– Option 2 (Composite, 30° twist): Balanced energy use with improved airflow.
– Option 3 (Timber, 60° twist): Least efficient due to low thermal mass.
Conclusion
Best Design: Option 2 (20 stories, Composite, 30° twist)
– Strong structural performance
– Optimized material efficiency
– Improved energy efficiency through natural ventilation
This approach using Dynamo BIM enables efficient high-rise designs, balancing strength and sustainability.
