Hardware & Software Requirements

Hardware and Software Requirements to run ENERCALC SEL

Any typical computer manufactured since 2007 should be more than adequate to run ENERCALC SEL. Of course, the more powerful your computer is, the better ENERCALC SEL will perform.

In general, the requirements are:

  • 820 MB of hard disk storage upon initial install. Including update installers that you will download as the software is updated each month, figure 1.3 MB total. 
  • 65 to 85 meg (not gig) of RAM to run the program
  • Windows 10, Windows 11, or newer versions of Windows. Note: Windows Home editions are not supported due to feature limitations of that edition.
  • ENERCALC Cloud users can use Windows, Mac, Linux, & mobile HTML5 devices
  • 64 Bit Windows is required for our installed software (Our installed software has both 32 and 64 bit components)
  • 1682×933 minimum screen resolution at 100% (normal) scaling
  • Internet connection to get updates
  • No other software is required.


Hardware and Software Requirements to run ENERCALC for Revit

Any computer that can capably run Autodesk Revit will be fine for running ENERCALC SEL + ENERCALC EFR + Autodesk Revit. You must have a full license for Autodesk Revit. Add-ins such as ENERCALC for Revit are not allowed to run on Revit LT. 

Of course, the more RAM and better CPU and GPU you have, the better this powerful trio of software will perform.


Installation and Licensing Details

ENERCALC has a simultaneous active seat license model. This means that you have the flexibility to install the software on any computer where you might like to use it.

Our license manager grants licenses on a seat-by-seat basis, allowing simultaneous use up to the number of seats you’ve licensed. This does not require uninstall / reinstall sequences that tend to consume user and IT staff time.

Installed seats and cloud seats are equivalent to the license manager. For example, if you have purchased a 10 seat subscription, you can have 8 active users using our installed software while 2 other users are logged in and using the software on our cloud platform.

Our internet-based license manager (also called “activation”) uses standard HTTPS API calls to validate license use. 

An example: If you have a 2 seat license, have activated the software on 2 computers at the office, and will be working at home for the weekend, you can click “Internet Deactivate” on one of the office computers and then click “Internet Activate” on your computer at home. Only a brief moment of Internet connectivity is needed for activation/ deactivation. If you forgot to deactivate the office computer before leaving there is no problem….we have a method of handling that common occurrence that does not require contacting our technical support team. You can handle it yourself quite easily from within the ENERCALC software.
