What our customers are saying

"We’ve added IES to our specification as our preferred modelling software because of the success we’ve had with it. The support we’ve had from IES in the package we’ve got is great and we’ve just invested in some more training as well."

Perth & Kinross Council

"IESVE is a great tool for complex simulations when energy performance, HVAC operation and daylight calculations are the main questions. When a combination of different options is being assessed IESVE is able to make detailed calculations to test assumptions before honing in with detailed HVAC performance simulation."
