UK-Dwellings + JPA-SAP

A unique 3D graphical interface to JPA SAP 2012 (9.92) that links directly to SketchUp and Revit.


iSAP is a low cost SAP solution developed by IES in conjunction with JPA|TL. Linking JPA’s easy to use SAP design tool with IES’s 3D graphical user interface, this unique proposition saves users time and money.

As IES has also created integrated plug-ins to SketchUp™ and Autodesk® Revit®, users can uniquely undertake these compliance calculations directly from a SketchUp or Revit model if desired.

iSAP is a bundle consisting of the following software:

  • IES ModelIT
    IES UK Dwellings
    JPA SAP 2009/2012

UK Dwellings replaces IES’s Part L1 module and existing users are eligible for upgrade offers.

The nature of IES’s software also allows users to easily add other UK compliance and performance analysis, so you can compare and contrast how meeting compliance criteria actually affects the building’s performance.
