TEGNOS Moving in a New Direction!
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.

Although the subject of our research is changing, we will
continue to provide an objective approach to the issues we
address, just as we did for the construction industry. As before,
we will remain focused research, education, and advocacy that
can be used to can be used to increase understanding of
critical topics. In view of our new research  focus, TEGNOS has
adopted a new motto:
“Bridging Boundaries," which succinctly
captures how we hope to build bridges of understanding and
shared purpose for all residents of our unique bi-national

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.
