A recent study from researchers at ETH Zurich, has introduced a novel modeling approach to evaluate the performance of 3D printed facade (3DPF) components.
Utilizing ClimateStudio, EnergyPlus, and Radiance within Rhino3D and Grasshopper, the approach accurately captures angle-dependent thermo-optical properties without intricate geometric representations.
Simulations conducted in Zurich, Switzerland, showcased the efficacy of 3DPFs compared to standard facades. Monthly energy demand profiles revealed lower overall energy demand and reduced cooling and lighting loads, especially in the horizontal cavity configuration. The 3DPF outperformed double-glazed units (DGUs) and offered comparable performance to DGUs with external shading.
Moreover, the 3DPF ensured consistent daylight illumination throughout the year, enhancing visual comfort within the space. Its diffuse light transmission qualities mitigated glare, contrasting with traditional facade systems.
Notably, the 3DPF achieved these benefits using a single material and simple manufacturing process, eliminating the need for additional shading devices or active control systems. However, it’s essential to note that 3DPFs may not compete with transparent facades in view clarity.
Future designs of 3DPFs will focus on customizing thermo-optical properties to specific climatic contexts, aiming for higher performance levels. By leveraging advanced modeling approaches, 3DPFs offer promising avenues for sustainable building design, optimizing energy efficiency, and environmental impact.
