Flixo Course – Model Thermal Bridges for High Performance Buildings
Monday Dec 17– Tuesday, Dec 18, 2018
“Great course! The Flixo training provided by Rolf and Chris gave me and other staff at NK Architects the hands-on base to prepare meaningful Thermal Bridge analyses. By integrating guided use of Flixo software with the standards required for Passive House certification, I am prepared to perform a key analysis function for high-performance building design.”
- Joe Giampietro, NK Architects
"We are extremely satisfied. It is incredible how much easier and more practical Flixo is than the software we previously used. Absolutely fantastic.”
- Florian Speier, Zola European Windows
2-day course, participants will explore thermal bridge modeling using Flixo to
be able to understand the impact of design details on the energy performance of
High Performance Buildings/ Passive House Buildings. We will first cover the concepts and
protocols for thermal bridge modeling. Then, participants will have the
opportunity to model several common thermal bridge types using Flixo, with
guidance from the instructors. By the
end of the course, participants will have completed at least two thermal bridge
models. All participants should arrive with the 30-day free Flixo Trial
software (version 8) pre-loaded on their computer. For
first time users/purchasers of Flixo, you are eligible to include a 1-yr Flixo
Energy Plus license & usb dongle to your registration (a $444 value) for
limited to first 20 registered.

Rolf is a Research Fellow for the Center for Sustainable Building Research at the University of Minnesota as well as a CPHC. He learned how to model and calculate thermal bridge heat loss while studying Passive House enclosures for his Masters of Science thesis in Norway. As part of the thesis, he developed a comparison of typical thermal bridge details for 8 different Passive House enclosure types. Since 2011 Rolf has provided thermal bridge modeling for a variety of commercial and residential projects including certified Passive Houses.
Chris is a CPHD & Trainer with Regenerative Design LLC and a Certifier with CertiPHIers Cooperative. He has provided design support and energy modeling services since 2008. Through CertiPHIers, Chris has certified Passive House projects in the US and Canada. In addition to his work with CertiPHIers, Chris teaches sustainable design, energy modeling, and renewable energy. He holds a MS in Architecture from the University of Minnesota.
