Kristof Irwin is the Director of Building Science at Positive Energy, a specialty MEP engineering firm for custom residential architecture projects, and the Host of the Building Science Podcast, making this a fun "interview the host"-style chat.

In this episode, we talk about the growth Kristof has seen in the Passivhaus space since its early days in the US, the power of Systems Thinking, the role people's worldviews/paradigms play in maintaining the status quo, the need to shift people's paradigms when it comes to what a building can and should provide, and much more.
