November 1, 2018. For over 10 years, TEGNOS Research has focused on the construction industry, with a special emphasis on energy efficiency, sustainability, and resiliency. However, after our
permanent move to Southern Arizona just a few miles from the Mexican state of Sonora, we have become increasingly focused on this unique region commonly known as “The Borderlands.” As a result,
our current research is targeted toward important environmental, cultural and economic issues that impact those who live in the border regions of the United States and Mexico.

For past clients, we will continue to make available much of the building envelope research we have published in the past. Many of the papers previously published, including articles addressing
equivalent uniform annual cost, net Carbon reduction, and building resilience remain relevant and in-demand. For more information regarding our library of building envelope articles, please visit our
Research Archives.
