In this 16 hour course, you will model thermal bridges using Flixo and understand the impact of design details on the energy performance of high-performance buildings/ Passive House buildings. We cover the concepts and protocols for thermal bridge modelling. Then, you will model several common thermal bridges using Flixo with guidance.
This course includes a four-month “training” Flixo Energy license (a value of $165 USD) for students who have not previously purchased Flixo Energy. Students who already have the Flixo software may be eligible for a discount and should reach out at info@passivehousecanada.com for further information.
Information about flixo can be found here.
