Sustainable Building Materials: Jugendstil Façade Meets Digital Fabrication
Sustainable building materials play a crucial role in today’s architecture. Recently, a student team at the Technical University of Munich developed an innovative façade system inspired by Jugendstil. This project combines heritage design with digital fabrication to create a sustainable residential façade near Heidelberg, Germany.
Project Details
| Detail | Description |
|---|---|
| Project Type | Residential Façade System |
| Location | Heidelberg, Germany |
| Developer | TUM Student Team under Prof. Kathrin Dörfler |
| Façade Area | Approx. 500 m² |
| Floors | 5 |
| Usage | Residential |
Materials and Technology
The team used selective paste intrusion (SPI), a 3D printing technique, to fabricate concrete mixed with recycled glass. This choice of sustainable building materials reduces waste and improves thermal performance.
Façade Performance Comparison
| Façade Type | U-Value (W/m²K) | Thermal Insulation | Weight (kg/m²) | Notes |
|---|---|---|---|---|
| Traditional Stone Façade | 2.4 | Limited | 45 | Heavy, high embodied energy |
| 3D Printed Concrete Façade | 0.85 | High | 18 | Lightweight, customizable |
| Double-Glazed Glass Façade | 1.4 | Moderate | 30 | Common in commercial use |
Design and Performance
Moreover, the façade’s organic shapes, modeled with NURBS, mimic Jugendstil motifs. Sustainable building materials contribute to these forms, providing sun shading, reducing heat gain, and improving energy efficiency. Furthermore, each block locks into place via a wave pattern, easing installation and reducing errors.
Material Efficiency through Simulation
| Design Type | Material (kg) | Savings (%) | Structural Strength (MPa) | Comments |
|---|---|---|---|---|
| Traditional | 25 | 0 | 35 | High material use |
| Optimized (FEM Simulation) | 18 | 28 | 33 | Less material, strong |
Human Insight and Future Potential
An engineer involved said, “Using digital tools to pre-correct installation issues is a real breakthrough.” This approach shows how sustainable materials used in building, combined with smart fabrication, can transform construction practices. Also, a team member noted, “We create façades that honour the past and embrace the future.”
