Systems

Describe the building’s HVAC and domestic hot water systems, and its schedules for monthly data.

For: AnalyzerWhere: Home › Systems card

Steps

  1. On Home, click the baseline’s Systems card. The window is named System Setup, or System & Schedule Setup for monthly data.
  2. On HVAC & DHW Systems, describe the predominant system under Primary HVAC with Heating/Cooling Capability, Air Distribution System, Zone Terminal Type, System Configuration, Heating System and Hot Water Loop. If part of the building has a different system, describe it under Secondary HVAC. Then complete Chilled Water Plant and Domestic Hot Water System. Options that don’t apply are grayed out automatically.
  3. For monthly data, complete Lighting & HVAC Schedules (required) and, if you can, Optional Inputs.
  4. Click Save Settings.

On a calibrated baseline, saving a change to the HVAC systems or schedules sends the baseline back to preparation. It leaves the Benchmark and Energy Audit lists until you check inputs and run the calibration again. A change to the domestic hot water system alone updates the model without a new calibration.
