About IES

Leading global innovator of sustainable analysis technology

Home   /  

IES is a global climate tech company delivering innovative software solutions and consultancy services to decarbonise the built environment. Over the last 30 years, we have built a solid reputation as the leading global innovator in integrated performance-based analysis and we're now home to the largest building physics analytics team in the world.

Supporting resource-efficient, healthy and cost-effective built-environments, we simulate and analyse data to give those involved in the design, retrofit and operation of buildings the information needed to make smarter, more sustainable decisions with confidence.
 
Our unique software and technology is supported by expert consultancy. And our dedicated R&D department ensures our analytical tools and industry knowledge stays pioneering and innovative.

Our Mission

IES is on a mission to decarbonise the built environment. Through relentless innovation, collaboration, and advanced software solutions, we empower those involved in the design, retrofit and operation of buildings with the tools and consulting expertise they need to deliver high performing, sustainable buildings that are better for our planet, and the people that use them.

Our Values

IES staff working

From building physics specialists and software engineers to highly qualified consultants, we employ people who are committed to sustainability and invested in what we do.

We pride ourselves on our team of friendly, interesting and diverse people from across the globe. 

As a company, we are profoundly aware of the need to reduce our dependency on fossil fuels and conserve the Earth’s natural resources. Everything we do is focused on delivering technology that reduces the impact buildings and cities have on the environment. 

Because of this, the scope of our products and services covers new build developments, building operation, refurbishment of existing buildings, masterplanning, and integrated heat/cooling/power/renewable networks. It can be applied whether looking at a building in isolation, or as groups. 

Innovation is at the heart of what we do. The IES Virtual Environment (IESVE), when it was first launched was pioneering, and today we continue to invest in research and development to ensure we stay at the cutting edge.

Our dedicated R&D Division has a reputation for creating strong R&D proposals and delivering innovative commercial projects. We are always looking for better ways to do things so that we can provide our customers with the most sophisticated, cost effective and usable software.
