Digital Twins - Improving Building Performance at Every Stage

At IES, we believe Digital Twins are the key to decarbonising the built environment. Our performance Digital Twin technology combines physics-based simulation, real-time data, machine learning and AI to create a dynamic virtual replica which is scalable from a single building to an entire campus, city or portfolio. Responding and behaving like its real-world counterpart to provide detailed insights across a range of building performance metrics and empowering informed decisions on how to reduce energy, lower costs and work towards net-zero goals.

Unlock the Benefits of Net-Zero Buildings

Buildings are complex, dynamic systems that constantly change throughout their lifetimes. Our tools understand this and integrate across the entire building lifecycle, from initial design or retrofit, through commissioning and ongoing operation, to ensure your building(s) stay on track towards zero-carbon goals.

  • Balance Energy, Carbon and Cost alongside Comfort, Health & Wellbeing
  • Bridge the Performance Gap between Design and Operation
  • Mitigate Energy & Climate Risks
  • Achieve Net-Zero Goals & Regulatory Compliance

Make Better Decisions

Digital technology is becoming a key enabler to understanding and improving how our buildings perform. Our digital twins translate data from various sources, including your BMS, utility bills, IoT sensors, and other metering infrastructure. Combining with simulated data to deliver actionable information that provides confidence in net-zero building investments and operational strategies

  • Optimise Building & System Operation
  • Develop long term Net-Zero Investment Plans
  • Minimise costs of Decarbonisation
  • Monitor progress towards Net-Zero Goals
