Carbon-Negative Building Systems

The BattWall system is described as a modular, cement‑free wall technology that integrates structural performance, thermal mass, and sodium ion energy storage within a single monolithic assembly. According to the project materials, each wall incorporates natural high mass materials arranged in three functional shells that provide load bearing capacity, insulation, vapor openness, fire resistance, and distributed energy storage. The system is positioned as CO2 negative due to its plant based composition and absence of conventional binders such as cement or gypsum. The campaign outlines a demonstration house intended to validate the structural, environmental, and energy performance of the technology under real conditions, supported by prior laboratory testing of compressive strength, thermal behavior, and material stability.

The project emphasizes the integration of sodium ion modules into the wall structure to enable buildings to store and regulate their own energy. The modules are designed to be replaceable, allowing the structural body to remain permanent while energy components can be upgraded over time. The campaign also highlights an embedded sensing and analytics layer that monitors temperature, humidity, structural behavior, and energy flow to support long term performance assessment. The demonstration house is presented as a proof of concept for scalable natural material construction that combines structural function with distributed energy storage, with the broader aim of enabling energy independent residential buildings.
