What our customers say about our solutions


"For us, IESVE is our all in one tool for doing loads, energy, daylighting, etc. Doing loads analysis is simple to run especially with the parametric tool in the VE. This tool allows us to test ideas and get results quickly efficiently, and the results are accurate. We now use the VE for all of our projects. On a recent office project, using the VE, we were able to improve glazing, reduce mechanical system size, and save the owner money all through the results of our analysis."

"IES actively listens to and responds to the needs of its customers. Our mainstream design teams have given much deeper commitment to the use of the VE – the VE is not just for our one-of-a-kind high performance “jewel box” projects. We are taking advantage of the much more user-friendly load reports on our everyday work. The graphics and visualization tools built into the VE are making it much easier for our teams to understand and optimize system performance and sizing."
