Web-based residential building energy efficiency compliance software

August 2020
Gallery StepWin 1
Gallery StepWin 1


StepWin is an Ai-powered web-based software for home builders. Builders input general project information in StepWin as well as the type of building assemblies they are considering to build. StepWin looks at all possible assembly configurations (thousands to millions) and cherry-picks the best performing ones according to construction costs.

This product is a response to the environmental efficiency regulations popping up everywhere around the world and causing a revolution in the building industry. As a consequence, the residential builders are being pushed to make high-performance homes, but the existing physics-based energy modeling tools do not have the scale nor the thoroughness to assess all possibilities, making the current process costly and risky. StepWin is powered by our, first of its kind, proprietary Rapid Building Energy Simulation Tool (R-BEST) which is 1,000,000 times faster than the traditional physics-based simulation tools. It also incorporates construction costs into this process, which has been another key missing piece. With these technologies, StepWin can tell homebuilders where to invest their budget to maximize the value of their build for themselves and their customers.simulation tools.
