EZ Sim is the next step in energy accounting. It uses actual utility bills to reveal the patterns of use in commercial buildings.

• Diagnoses energy patterns and consumption
• Calibrates savings estimates to agree with actual energy usage
• Estimates energy end-uses within the facility
• Verifies vendor claims for energy products and services
• Generates performance targets to compare against actual energy bills

EZ Sim is a quick spreadsheet tool that is equivalent to a sophisticated engineering analysis. It's designed for resource conservation managers and facility operators. You don't have to be an engineer to use it.

EZ Sim uses actual energy bills and available information to reveal the patterns of energy use in a building. So, the cost to operate EZ Sim is almost nothing.

EZ Sim lets you use utility bills to calibrate a simulation of a commercial building in an interactive graphic window. Once it matches the building's utility bills, the simulation model can provide reliable estimates of potential conservation savings. So, you have assurance that the savings estimates are realistic.

With EZ Sim, the calibration process reveals how energy is used within the facility to help diagnose why there is excessive consumption or poorly functioning building components.

Best of all, EZ Sim can be used to predict what future utility bills should be and can help you set performance targets to determine if your installation is on track. This is the simplest form of building commissioning -- and at very little cost.
