IESVE 2019

IESVE 2019 offers a common theme of reduced simulation times, new metrics and new ‘easy-to-use’ workflows.

What's New?

Take a tour of all the latest features in IESVE 2019 below. New to the software? Visit our Virtual Environment page to discover more about our solutions for building energy modeling, HVAC loads sizing, building energy compliance and more.

New Schematic Geometry Wizard

The new schematic geometry wizard offers a quick simplified approach to geometry and model creation.

  • Select a building footprint shape and enter building dimensions, glazing percentage by orientation and number of floors to create a quick schematic design model. 
  • Useful for early-phase analysis E.g. plant equipment sizing estimates, energy/carbon estimates.
  • Compliance with ASHRAE Standard 209 and LEED Integrative Process.
IESVE Glazing Library

New Glazing Database

Easy import of pre-configured glazing assemblies.

  • Target ranges of U-value and SHGC.
  • Manufacturer-specific library of popular glazing assemblies E.g. Vitro/Solarban, Guardian/Sunguard, Viracon/VE, etc. 
  • Includes manufacturer examples of dynamic shades and translucent shades (new solar algorithm).  
  • Library includes compliance glazing assemblies for ASHRAE 90.1, IECC and Title 24.

Daylighting Enhancements

  • New Glare Metric:  Daylight Glare Probability
    • Click here for more details. 
  • RadianceIES material properties integrated within Apache interface for loads and energy modeling. 
  • Faster Daylight Simulations:
    • Sky resolution options to improve simulation speed for all climate-based daylight simulations.
    • Use your GPU for faster daylight & glare simulations via integration with Accelerad. Email to get access to this feature.

HVAC System Design Wizard

New wizard-based approach for HVAC System(s) design.

  • Automatically creates multiple detailed ApacheHVAC systems, assigns zones and plant-based equipment. 
  • Global editing of waterside plant/equipment for multiple AHUs.
  • Automated sequencing of actions, including room loads, system sizing, energy simulation and report generation. 
  • Can be launched in ‘Compliance-mode’ which automatically creates the HVAC-systems for ASHRAE/IECC/NECB baseline models.
  • Creates HVAC equipment schedule.

Energy Model Output Report

A single-page energy simulation output report can be launched from VistaPro, which includes an overview of building energy model performance.

  • Annual site energy, source energy and CO2 emissions breakdown.
  • Performance graphics include:
    • Site energy dashboard by month.
    • Energy Use Intensity (EUI) breakdown.
    • Sankey diagram of fuels-to-energy end-uses.
  • Breakdown of fuel cost, along with peak demands, date & time.
  • Design-guidance graphics for a ‘top 3’ contributors of peak energy sources, and onsite power generation contribution.



Florida Energy Code Compliance

As part of IES’ ongoing commitment to providing energy code-compliance solutions in North America, IESVE Software is now certified by the Florida Building Commission for the 2017 Florida Energy Code.

  • Certified by the Florida Building Commission. 
  • Compliance achieved through the ASHRAE 90.1-2013 ECB Navigator.
  • Florida-specific budget building is automatically created, per FBC requirements. 
  • Florida specific compliance reports are generated.
  • IES training courses certified for continued education (CEU/PDH’s) by Florida Board of Professional Engineers.

AIA DDx API Connection

A new AIA 2030 Challenge Navigator to upload detailed energy model data & results to the AIA 2030 DDx site. 

Engineers & energy modelers have options to upload detailed energy model data & results to the AIA 2030 DDx site, with the same functionality integrated into various ASHRAE & IECC Navigators.
