NEW July 2020: Construction Workforce Training for Building Performance Series

Construction workforce training series

Northern Colorado HBA, City of Fort Collins Utilities & Building Services and Xcel Energy present a series of FREE workforce training and education sessions. These sessions aim to provide tools and understanding of the impacts that evolving building code have on building performance.

We’ll explore topics each week, from July 10th-Aug 14th, ranging from how building science relates to code – in easily relatable examples, different code paths, building air tightness and ventilation, and what the future might look like with respect to Zero Energy Ready Homes (not as far a reach as you may think in Fort Collins and northern Colorado).

  • July 10th, 2020,  8-9:00 am – FREE Webinar series
  • The first in the series – The foundation: Basic Building Science - Review other session info in the registration link below
  • Presenter: Robby Schwarz - Principal, BuildTank Inc.
