  • Dynamic information of new events and online content (new scripts, reports, etc.).

New Daylight Simulation Enhancements

  • Spatial Daylight Autonomy (sDA) & Annual Sunlight Exposure (ASE) graphics improvements and shown on working plane of 3D model viewer.
  • Contoured working planes.
  • Global processing capability to entire model for sDA and ASE
  • Rule-based daylight-sensor locations (e.g. by orientation) for daylight-harvesting.

Faster Simulation Speeds

ApacheSim is now up to 85% faster using the new parallel simulation mode.

  • Simulations can be divided by:
    • Number of cores (automatic)
    • Number of months (user choice)
  • Partial results sets can be viewed in VistaPro

Note: This feature is keyed seperately. Please contact

New VRF (Variable Refrigerant Flow) Capabilities


Detailed VRF capabilities in ApacheHVAC include:

  • Air source VRF with heat recovery
  • Water source VRF with heat recovery
  • Fully integrated with detailed HVAC modeling (e.g. for ASHRAE 90.1 etc.)
  • Complete with performance curve data sets
  • Auto-sizable prototype systems available
