With your own Soletair Power HVAC-integrated CO₂ capture system installed in the building, you can earn more LEED
Turning buildings into carbon sinks
With six systems already deployed, we’re aiming to scale up carbon capture with our distributed Direct Air Capture systems across the globe. Our modular Building HVAC-integrated CO2 Capture Units capture CO2 from the air, reduce carbon emissions onsite, save on energy costs, earn LEED & WELL points, and ease ESG compliance with emission legislations like LL97, 45Q & EPBD.
Our modules add no extra noise and capture CO2 even at ambient airflow rates, making them ideal for integrating within urban infrastructures like buildings, shopping malls, or data centers.

We help decarbonize real estate
A carbon sink is a reservoir that stores carbon dioxide permanently after capturing it from the atmosphere.
Direct air capture (DAC) is a technology that uses chemical materials to capture carbon dioxide from the atmosphere. When air is moved over these materials, they selectively capture the CO2, allowing the other components of air to pass through.
One of the biggest benefits of direct air capture is siting flexibility. DAC does not require arable land, which can minimize impacts on food production or other land uses. DAC is needed alongside plantations because planting a trillion extra trees will remove only a quarter of the CO2 currently in the air (Ref: BBC). DAC also has a limited land and water footprint and can be installed in places close to suitable CO2 storages, thus eliminating the need for CO2 transport.
High concentration of CO2 in the air indoors has a direct influence on how people think (Ref: Harvard University). The standard indoor CO2 level is expected to stay between 450 and 600 ppm, which is slightly above the normal levels in outdoor air (414 ppm). From 1,000 ppm, room occupiers start to feel dissatisfied and with every 400 ppm increase in CO2 concentration, our cognitive function score drops by 20%. CO2 undercuts our ability to perform in thought works at full potential.
In addition to offsetting a building’s CO2 emissions, HVAC-DAC integration can reduce HVAC’s operational costs, and supply better air indoors. This also brings in the potential to create a localized supply of alternative energy sources.
For a standard ventilation unit handling 3.3 m3/s, our Building-HVAC-Integrated CO2 Capture Unit can capture 47 kilograms of carbon dioxide per day per module. On average, there are six modules per building. So it’s around 300 kg/day or 90 tonnes/year from each average commercial building.
