Abstract
This study introduces a new bio-façade system in Indonesia, bringing innovation to sustainable architecture. The design focuses on mapping, modeling, and simulating the façade. The algae modules, categorized as Dark, Standard, and Light, adjust to sunlight levels, making the building more comfortable. Simulations show a significant reduction in the Overall Thermal Transfer Value (OTTV) to an impressive 35 W/m², setting a benchmark for energy efficiency. The project generates 131,460 kWh annually, reducing 295,346.8 grams of CO2 daily. It stands out as a model in sustainable architecture, demonstrating the potential of biophilic design in urban environments.

Facade Thermal Mapping & Algae Module Placement Optimization#
In this phase, mapping assessed thermal exposure for each facade section, crucial for simulating OTTV calculations. After determining OTTV values in the first [1] and second [2] simulations, the third simulation [3] identified optimal Algae module placement along solar path lines in Jakarta—specifically in the North, East, and South directions.
Biofaçade System: How the Façade System Works#
When the building is exposed to substantial sunlight, the density of algae increases, creating additional shade and contributing to the maintenance of thermal and visual comfort. In the algae module, three specific types are distinguished: Dark, Standard, and Light. The algae facade facilitates adaptive shading in response to sunlight. As the building receives more sunlight, the algae density grows, providing heightened shading that ensures ongoing thermal and visual comfort.
