By Suzanne Wallace on Tuesday 2 July 2019

We’re delighted to announce that IESVE 2019 is now available via our download centre.

IESVE 2019 offers a common theme of reduced simulation times, new metrics and new ‘easy-to-use’ workflows. Here’s some of the key features of the new release:


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

  • Enter building orientation & footprint (building type, shape, storeys etc.) and an entire model is prepared for you in one click


SunCast and ApacheSim have been enhanced to enable solar tracking through non-connected zones and translucent shades.

  • Translucent surfaces, such as glass brise soleil, can now be modelled
  • Algorithm can track the path of the sun through non-connected zones – previously only possible through connected zones
  • Meshes or lattice shading devices can now be modelled with a single transparent surface drastically reduced computation and modelling times


HVAC Systems can now be streamlined in 5 easy steps or less!

  • Simple and initiative UI for system creation, assignment and calculations
  • Zoning, airside and waterside can be selected from list
  • Full HVAC systems including proposed and baseline models plus ASHRAE loads calculations, sizing and reports created within minutes

Note: CIBSE Loads calculations to follow


Daylighting simulation times reduced!

  • RadianceIES simulations can now be carried out quicker via Accelerad – up to 20 times quicker!
    • Accelerad uses the power of the GPU to provide faster static and dynamic simulations.
    • The more powerful the GPU the faster your simulation will be.
    • Email support@iesve.com to get access to this feature.
  • Sky resolution enhancements can speed up your simulation by 25%!
  • Daylight Glare Probability Metric – developed in line with customer feedback
