Utilizing building ventilation systems to capture atmospheric CO2 and generate three-way benefits - reducing emissions, environmental benefits, and reducing CO2 exposure for the residents. Over half of the world’s population is currently urban, with predictions that this number will likely grow by 1.56 billion over the next two decades. As a result, we will see new megalopolises emerge, and an exponential increase in the construction of new buildings and CO2 emissions. This surge in the number of people living and working in buildings will only reinforce the challenge of guaranteeing the best air quality levels possible. A high concentration of CO2 has been proven to make people feel dizzy, tired, and sleepy. A Harvard study shows that for each 400-ppm increase in indoor CO2 concentration, our cognitive function score becomes 20% lower. Ours is the most affordable technology for increasing overall employee wellbeing by preventing their productivity from decreasing by 20%. If buildings can be used as CO2 capturing machines the lifetime emission can be offset. One single system for building ventilation of 3m3/s can capture 20 tons of CO2 per year. In a single building, one might have, for example, 20 ventilation units. So, per building, it is 400 tons of CO2 captured per year. When the system is used with renewable electricity (5kWh energy required per kilo CO2 captured) (20g/kWh) the emission is 100g when 1000g is captured. By transforming buildings into carbon sinks, net-zero targets can become achievable. Buildings become an active protector of environments and contribute to global negative CO2 emissions. Soletair Power captures carbon utilizing buildings' ventilation systems, which achieves up to a 50% reduction in emissions, supports employee wellbeing, and increases productivity. Soletair Power’s modular solution operates with a plug-and-play approach, enabling any company to install and use Direct Air Capture. The captured carbon can be reused as a non-fossil-based resource in a wide array of applications, effectively rewinding the impact of CO2.
