Quickly and easily undertake operational modelling using real-building data

IES-ERGON makes enhanced operational modelling a reality 

Unlocking the value of operational data it allows you to easily upload, understand and prepare any real building data onto one cloud platform ready for simulation and comparison in IESVE. With significant enhancements now included, the 2018 version of IES-ERGON is at the cutting-edge of digital engineering solutions for Existing Buildings.


Taking the effort out of creating operational and calibrated energy models, IES-ERGON enables VE Engineers to quickly and easily upload data from building/energy management systems, meters and sensors, alongside real weather data. Users can then create year-specific operational profiles for use in the Virtual Environment and make direct comparisons of metered and simulated data, enabling model calibration. It can handle any time-series operational data down to 1 minute, and automatically irons out discrepancies in time steps, while helping fill missing data gaps.
