Calculate and Optimize Building Carbon Footprint Easily
Calculate Building Carbon Footprint from all life-cycle stages and operational emissions. Submit results to get green building certification credits.

What is Building Carbon Footprint?
Building carbon footprint (CO2) is the total amount of greenhouse gases produced throughout the life-cycle of a building. It includes emissions from energy use (operational carbon) and materials (i.e. embodied carbon, capital carbon).
Calculating and optimizing your building carbon footprint makes for better investments in construction projects, helps win new clients and is demanded by regulators and certification schemes.
From Building Carbon Footprint to Life Cycle Assessment
Life-Cycle Assessment (LCA ) acts the industry standard methodology in quantifying the CO2 footprint of a building.
By automating LCA calculations, you can get instant access to your Building Carbon Footprint performance.
