Enercalc Cloud - A New Frontier

Try ENERCALC Cloud now and see for yourself!


Welcome to the end of Installations, Activations, Updating, Maintaining Multiple Computers, Shuffling Project files around.

You can use your ENERCALC Software licenses anywhere - From your Windows PC, your Mac, your Tablet, your iPad, a friend's Laptop, the Hotel's Business Center . . . . . . Anywhere.


ENERCALC now offers ENERCALC Cloud. Think of it as Structural Engineering Library in the CLOUD - all 40+ modules. These online implementations feature familiar graphical user interfaces and nearly the same capabilities as the installed software. Powerful, simple, fast and available whenever you need it!

In addition, ENERCALC Cloud offers a third application called ENERCALC 3D, a powerful 3D finite element analysis and design program.

The Amazon Web Services (AWS) computing infrastructure provides unparalleled capabilities, reliability, and ultra-high speed global availability. Their platform offers the infrastructure we needed to provide our advanced software deployment with 24/7 availability.

ENERCALC Cloud uses AWS data centers in Virginia, Ohio, Northern California, Tokyo Japan, Mumbai India, Sydney Australia, and Frankfurt Germany.



  • USE THE SOFTWARE IMMEDIATELY - Zero startup, zero configuration. No installation, configuration, or activation.
  • USE THE SOFTWARE YOU ALREADY KNOW - SEL in the cloud has nearly the same user interface and capabilities as the installed software. You are using THE SAME software as the installed version. You'll be productive immediately - with no re-training!
  • 64 BIT MULTIPROCESSOR SPEED - Our Cloud servers are all 64-bit multi-processor speed demons that provide extreme calculation performance.
  • YOUR PROJECT FILES ARE SAFE - Project files in the cloud are replicated to multiple AWS locations for safety and every file save makes a new backup. Plus, 24/7 global availability
  • NO UPDATES - The software you use is always up to date. New versions are instantly available...globally.
  • NO IT GUY REQUIRED - No IT management in your office is required. Give your IT contractor (and your budget) a break.

What is Cloud Computing? Cloud computing means that all of the program operation is on a server on the Internet. In our case, "on the internet" means on the secure, powerful Amazon Web Services (AWS) facilities also used by MLB, NFL, SEC, major banks and many more demanding enterprise-class customers. Capability already built into your device’s operating system interacts with the running application to provide the user interface. All of the operation is done remotely on our servers.

Easily move projects between Cloud and Installed software! You can EASILY move your current ENERCALC Project Files to our secure cloud storage on Amazon Web Services (AWS). They are stored via AWS S3 secure cloud storage, where every version you save is backed up locally and at a second AWS location. It's simple to export a project from the Cloud version back to your computer for use or backup.

Working on a project and want to finish at home? No worries! End your work session at the office and launch at home. Your data is in the same cloud location available to you anywhere! Laying by the pool in Kauai and need to revise a design? Just launch our application on your tablet!

MOBILITY: Your engineers can access your calculation project files wherever they are using Mac, Windows, Linux, Android (any HTML5 browser) devices anywhere.

REDUCE COST AND EFFORT: With ENERCALC SE, there is no software to install, no activation codes to keep track of or enter, no activation, no updates to install, no shuffling project files between computers, and you always have the latest software releases. Cloud computing simplifies all aspects of computing! And you still can print locally on your own printer.

EASY MIGRATION: Easily upload your project files via our secure upload connection. Your project files are moved into our secure AWS S3 storage and are replicated at a second AWS data center for even more safety. Starting up your Cloud usage is simple. The connection between our cloud servers and your device is fully encrypted using the industry best practice and technology standards.

See for yourself, give ENERCALC SE Cloud a test drive!
