We address the data and communication gap in the small residential construction sector – by far the most prevalent, yet inefficient, types of buildings. Our flagship product, StepWin, and our Ai-powered technologies such as the Rapid Building Energy Simulation Tool (R-BEST) supply our customers with a new generation of building designs capable of maintaining a high level of occupant comfort without an increase in construction costs. We serve a wide variety of clients ranging from governments of all sizes to homebuilders seeking the most fruitful investment. The City of Kelowna, the City of Kamloops, and the City of New Westminster are among our clients.
