1982 – ENERCALC, LLC (formerly ENERCALC Engineering Software) was formed by Michael D. Brooks, a California registered Civil and Structural engineer.
The initial software offering was a simple set of fill-in-the-blank engineering calculation templates using the Lotus 1-2-3 spreadsheet. Over the next 10 years the Structural Engineering Library grew into an extensive system providing calculation ability for common engineering design tasks.
1994 – 1996 – The software was rewritten to be independent of Lotus 1-2-3.
1996 – 1997 – A complete rewrite was completed for 32-bit Windows operating systems.
2003 – 2007 – The entire system was completely rewritten again to lay a foundation for the next decade of ENERCALC software offerings. The powerful, flexible design, such as the project file data model, built during this period allow great flexibility and continues to serve SEL in the 2020s. In 2007, we added internet-based license management and concurrent active use licensing – both were unusual for software at that time.
2015 – ENERCALC Cloud made its first appearance and quickly grew to several hundred users.
2018 – Additional substantial improvements followed, such as the introduction of 3D sketches.
2019 – We started the migration to subscription licensing and significantly improved our 14 year old internet license manager, bringing it up to the current technical standards of this time. This allowed us to offer an extra seat to users at no extra charge – in part so they could avoid deactivating before leaving for home, if they planned to get ahead of their work at home that evening.
2021 – We made significant changes to the software and simplified our licensing, allowing all SEL users to use the installed software and our cloud software for one low price. We merged RetainPro into SEL, adding 7 new modules for existing and new SEL users. We added ENERCALC 3D to SEL, providing powerful 3D FEM capabilities to SEL that were previously available only via our cloud platform. New FEM-based modules for Base Plate and Footing were added, with sophisticated – yet simple mesh capabilities. We added (optional, free) AWS-hosted project file storage for the installed software, which was previously available only to cloud users, allowing cloud and installed users to easily share files without Dropbox, OneDrive, etc.
2022 – We added support for IBC 2021 and invested heavily in internal code quality, performance, and efficiency – preparing SEL for its next steps. A change in ENERCALC ownership allowed Mr. Brooks to begin a well-deserved retirement after 40 years of service to ENERCALC users. All of the long-term ENERCALCers remained on staff to support engineers. In addition, we added additional developers, administrative, and infrastructure staff.
2023 – We’re going back on the road again. It’s been a while, other than appearances at Autodesk University 2021 and 2022. This year, please visit with us at NASCC – The Steel Conference in Charlotte NC in April and in November at NCSEA in Anaheim CA.
We continue to push the software to do more, while doing it faster – while keeping it accurate and simple to use.
ENERCALC, LLC is headquartered in Missoula, Montana. We have staff in 3 countries, including each mainland US timezone.
