Daniel Hahne began his HVAC industry career in 1985 when he accepted his first position working as an estimator for the HVAC representative organization, Norman S. Wright Co. SW, Phoenix. After years of estimating, Dan’s profession transitioned into contractor sales before he accepted a position at a newly established representative company in 2000, Air Specialty Products (ASP), currently known as ThermAir Systems. At ASP he learned how to support and sell to design development projects for large commercial and institutional buildings.

​

In 2008, Dan lobbied for and became ASP’s Engineering Salesperson. Leading industry manufacturers provided the educational resources for him to learn about high-performance building and types of equipment available to increase mechanical system efficiency as he became a regional resource for projects designed with decoupled active and passive hydronic systems, thermally stratified environments and 100% outside air systems.

​

Gaining market share through his educational approach, Varitec approached Dan to join the firm as a corporate “educator”, a role he accepted and advanced in the Desert Southwest as Varitec’s Director of High-Performance HVAC Solutions. During the pandemic, Dan created a webinar series based on ASHRAE’s Position Document on Infectious Aerosols. These webinars drew significantly from ASHRAE’s Epidemic Task Force website and other industry resources to address the nature and behavior of infectious aerosols in occupied zones and what protocols and products are available to reduce the risk of infection.

​

In 2019, two professional engineers invited Dan to co-author two articles for Engineered Systems (ES) Magazine, “Debunking the Myths of Chilled Beams.” This unique opportunity allowed him to expand his educational platform nationally by co-authoring and authoring five more articles of various topics for ES Magazine.

​

Dan has been an active member of ASHRAE since 2009. During his membership years, he has served as Chair of Sustainability for ASHRAE’s Central Arizona Chapter, and was a featured speaker for his local chapter on Fan System Effect, Debunking the Myth of Chilled Beams and on Thermally Stratified Environments. He was also a voting member on ASHRAE’s Standard 200-2015 committee on Methods of Testing Chilled Beams and is currently a member of ASHRAE’s T1.7P Committee for ongoing commissioning.

In December of 2021, to more effectively advance MEP solutions for high-performance buildings, he joined the AIA-Arizona Chapter as an Allied member and became an AIA CES accredited provider to encourage architects to become more involved in dialog with their mechanical engineers. Dan currently has fourteen AIA CES accredited presentations on a variety of topics..

​

As a Bachelor of Fine Arts graduate of the Slade School of Art, University College London and holding a Master of Fine Arts Degree in Sculpture from Boston University and taught fine art courses part-time for the Maricopa County Community Colleges. Dan’s educational background is uncommon in the industry and gives him a uniquely creative perspective within the HVAC mechanical engineering realm.
