INTEGRATED ENVIRONMENTAL SOLUTIONS LIMITED

Their core work

IES develops the Virtual Environment (VE) — an integrated building performance simulation platform used across the construction and energy sectors to model energy use, comfort, daylighting, and carbon emissions in buildings. In H2020 projects, they contribute their simulation and digital twin software as a core technology component, enabling partners to design, validate, and optimize building renovation and energy management strategies. Their role spans from BIM-integrated retrofit design tools to real-time building energy management systems, making them a key software provider for Europe's building decarbonisation efforts.

What they specialise in

How they've shifted over time

In the early period (2015–2018), IES focused squarely on BIM-based renovation tools for residential buildings — keywords like "collaborative design," "energy simulations," "retrofit design," and "small contractors" dominated, reflecting work on making energy modelling accessible for the renovation supply chain. From 2019 onward, the focus shifted toward digital twins, real-time building management, demand response, and decarbonisation at district and city scale. There is also a notable broadening beyond buildings into industrial energy, nature-based urban solutions, and even sustainable aviation (STARGATE), suggesting IES is extending its simulation platform to wider environmental domains.

IES is evolving from a building-level energy simulation provider toward a digital twin platform for district-scale and cross-sector decarbonisation — expect future work at the intersection of buildings, energy grids, and urban planning.

How they like to work

IES operates predominantly as a technology provider rather than a consortium leader — 9 of 18 participations are as a third party (supplying their VE software to other consortia) and 7 as a regular participant, with only 3 coordinator roles. Their 283 unique partners across 28 countries indicate they are a widely trusted, frequently invited software partner rather than a repeat-cluster player. Working with IES means gaining access to a mature commercial simulation platform and a team experienced in integrating their tools into diverse project workflows.

IES has collaborated with 283 unique partners across 28 countries, making them one of the most broadly networked building energy SMEs in H2020. Their reach spans all major EU member states with no single geographic cluster, reflecting demand for their software tools across European renovation and energy projects.

What sets them apart

IES owns the Virtual Environment (VE) platform — one of the few commercially proven, integrated building performance simulation tools in Europe. Unlike academic partners who bring research models, IES brings production-ready software that can be deployed in real renovation and energy management workflows. This makes them an ideal partner when a consortium needs credible, market-ready simulation and digital twin capability rather than a prototype.

Highlights from their portfolio

• NewTREND
  Highest-funded project (€632K) where IES coordinated development of integrated retrofit design methodology — their flagship coordinator role.
• StepUP
  Most recent coordinator role (2019–2024) focused on deep renovation uptake, signalling IES's ambition to lead market transformation beyond just tool provision.
• TwinERGY
  Represents IES's pivot to digital twins and prosumer energy communities — a forward-looking direction combining their building simulation expertise with grid flexibility.
