Note this feature was made available in VE 2018 Feature Pack 2. 

New Schematic Geometry Wizard

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.

Solar Algorithm Enhancement

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 reducing computation and modelling times

HVAC Systems Wizard

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

  • Simple and intuitive 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
