What Our Clients Say

Initially it was assumed that it simply wasn’t possible to achieve a six star Green Star rating in the tropics. However, the modelling from IES was so robust that we were able to refine our strategy to pick up additional innovation credits, enabling us to gain six star world-leadership status from Green Star and generate $450,000 a year in energy savings.

Carl N Gray
MGF Consultants

We chose IES because we were looking for a partner that was capable of developing a solution that was credible. We can already attribute over £500k of business to the connection with the VE. I cannot praise IES enough for their professionalism and for the help they’ve given us.

Richard Green
Daikin UK

What started out as a relatively simple project became a major engineering challenge, requiring an understanding of the complexity of seven constantly changing environments. Working with IES was like having a second engineer on-hand to help create solutions to highly complex problems.

Mark Gellaitry
Blackwood Partnership Consulting Engineers

IES and their VE software proved themselves over a long period during the concept and definition stages of the services design. Their knowledge of software allowed the level of definition to be easily altered as more information became available culminating in detailed energy, environmental and daylighting models of each major facility.
