VE Start-up Interface
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.

- Optimal Start control
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
- Variable flow condenser water loop
- 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
New Daylight Simulation Enhancements
