How It Works

Model Ease works by calculating both energy savings and penalties for your project using a wealth of weather data for your location. Model Ease uses hourly bin weather data to estimate project impact for each hour in an annual simulation, providing you with detailed monthly energy savings/penalty calculations.


Take the example of a chilled water supply outdoor reset project. In this project, the user defines a control strategy that modulates the chilled water supply temperature higher when the outdoor air gets cooler in order to reduce refrigeration energy. This strategy may have a similar control strategy shown below:

After thousands of bin weather calculations, the software produces easily discernable annual savings broken down by month. The calculations show

  • Fuel Savings/Penalties
  • Electricity Savings/Penalties
  • Total (Combined Fuel & Electricity) MMBtu Savings
  • Total Cost Avoidance
  • Simple Payback
