What our users have to say

Incorporating One Click LCA as a tool in the building design stage has helped us evaluate, prioritize and optimize our efforts in reducing the lifetime environmental impacts of the projects we design. With One Click LCA uploading, managing, and evaluating data has become very fast and easy through its automated process which links materials with relevant LCA data from the software’s abundant product database. One Click LCA provides the detailed information we need to implement design solutions which are substantially reducing the environmental impacts of our projects.
