A New Start-Page

Upon opening IESVE 2018 Software you will be welcomed with a new start page. Features include:

  • Pinned Weather data of your most common location settings
  • New Project creation: Prototype model import options, including ASHRAE 209 prototype models
  • Dynamic information of new events and online content (new scripts, reports, etc.)

Both new and experienced users will use the new start page as a launching point into their IESVE model.

Simulation Speed Enhancements

Simulations are now ~10 times faster by utilizing the new parallel simulation mode feature. Simulations can be divided by:

  •     Number of cores available
  •     Number of months (user choice)

Once the divided simulations are complete, they are automatically joined back together into one simulation result set.

Note: This feature is keyed separately. Please contact sales@iesve.com

Space Data Integration with System Parameters UI in ApacheHVAC

  • For ApacheHVAC Methodology, ventilation requirements and other Room-level  parameters set in Room Data and Room Thermal Templates passed to ApacheHVAC
  • Room values, such as ventilation, are summed for Zones in HVAC
  • Color-coded values can be edited or refreshed in ApacheHVAC.
  • Temp and humidity edited in ApacheHVAC feedback to Room Data.
  • Coordinated with PRM Navigator

Additional HVAC Enhancements

  • Optimal Start control for airside systems

  • Chilled water loop Supply Water Temperature reset per coil flow
  •  Improvements to System Parameters user interface
  •  Independent design-day scheduling and diversity settings for internal gains for Room/Zone Loads vs. System Loads vs. full dynamic Simulation
  •  New prototypes in the HVAC system library, including:
    • VAV systems with side-stream exhausted space (e.g., WC) drawing transfer air from the Principal space on the same layer (e.g., corridor)
    • Ventilation air separately delivered to Zone in a DOAS
    •  Air-source and water-source VRF systems with DOAS for ventilation
