LIAR – Living Architecture

The goal of project LIAR is to design and build a proof-of-concept ‘living architecture’ whose targeted breakthrough is to transform our habitats from inert spaces into programmable sites.

Living Architecture (LIAR) is a next-generation, selectively-programmable bioreactor. It is envisioned as an integral component of human dwelling, capable of extracting valuable resources from sunlight, waste water and air and in turn, generating oxygen, proteins, and biomass through the manipulation of their interactions.

A freestanding partition is composed of bioreactor ‘building blocks‘ which are conceived as standardized building segments or ‘bricks‘ that can be incorporated into common building construction methods.

The bioreactor LIAR unit is prototyped based on the operational principles of Microbial Fuel Cell (MFC) technology and Synthetic Microbial Consortia (SMC). The outcome consists of two building blocks: one programmed and configured MFC to produce electricity, and one SMC to purify air and water.

An array of bioreactor units act in parallel to a computer that is capable of both SENSING local conditions within a building and CONTROLLING the bioreactor system to optimize the the units impact on the building’s environmental state.

In the future, the LIAR unit can become a form of customizable, programmable micro-agriculture for installation in domestic, public and office environments. The technology could potentially address global scale challenges of urban sustainability and resource management.
