Microalgae Building Enclosures: Design and Engineering Principles

Author: Kyoung Hee Kim

Microalgae architecture is increasingly recognized for its biotechnical capabilities in achieving net-zero energy structures, while simultaneously fostering ecological sustainability and enhancing occupant well-being. 


“Microalgae Building Enclosures: Design and Engineering Principles” seeks to offer comprehensive guidelines, encompassing design, engineering, and biotechnical aspects, for the implementation of microalgae building enclosures.


These guidelines are crucial in establishing symbiotic relationships among the built environment, human inhabitants, and surrounding ecosystems.

4.6Gt CO² equiv. Emissions in the US in 2020

2. 5Gt CO² Sequestration Potentials

(54% carbon uptake of US’s emission)

Typical commercial buildings enclosed with biochromic systems can sequester 2.5Gt CO2, given 6 million commercial buildings available in the US

4.6Gt CO² equiv. Emissions in the US in 2020

1.4Gt Biomass Production

As a Food source

Microalgae harvest from urban framing using existing commercial buildings can feed 1.4 billion people (the estimate is based on a Spirulina’s 1g/liter growth rate.
