Our Value Propositions
- Our revolutionary biochromic technology plays a vital role in improving indoor air quality. By reducing CO2 levels and generating oxygen-rich air, it contributes to the well-being and health of occupants—an essential aspect of a healthy environment.
- Our system aids in achieving net zero energy and net zero carbon building practices while meeting rigorous certifications such as LEED, WELL, and Fitwel. This ensures compliance with stringent sustainability standards and acknowledges our commitment to creating environmentally friendly buildings.
- The exceptional photosynthetic performance of our system enables highly efficient, nature-based decarbonization. This not only contributes to the carbon-neutral goal but also facilitates the acquisition of carbon credits, further reinforcing our environmentally conscious approach while providing financial benefits.
- With the increasing awareness of global warming, the need for renewable energy sources is becoming more crucial. Biofuel, a biomass coproduct of our system, serves as a viable alternative to solar and wind power. The production of biofuel not only provides an effective solution for reducing carbon emissions but also helps us achieve our carbon-neutral goals.


Broader Societal Impact
- The process of decarbonization is significantly supported by microalgae, which represent roughly 10% of terrestrial plant biomass but are responsible for sequestering over half of the world’s CO2 emissions. To illustrate the impact, consider the scenario where all commercial buildings in the United States (approximately 6 million buildings) are equipped with biochromic enclosures. This implementation alone has the potential to sequester an impressive 2.5 gigatons (Gt) of CO2 annually, surpassing 50% of the total CO2 emissions produced by the United States in 2020.
- Resource conservation is effectively achieved through the retrofitting of low performing buildings with biochromic enclosures, resulting in reduced energy bills attributed to decreased heating, cooling, lighting, and ventilation requirements in buildings.
- Food and biofuel production are key benefits derived from microalgae biomass. This versatile resource has the potential to serve as a nutritional source for various life forms and as a renewable energy solution. To illustrate this potential, the biochromic enclosures installed on all commercial buildings across the United States can yield an impressive 1.4 gigatons (Gt) of biomass, which can be utilized as both a sustainable food source and an energy resource.


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.
