Rahul Shaw is the owner and principal architect at Tight House Architecture and Interior Design, specializing in single-family home renovations, additions, and new builds that go beyond the ordinary.

Michael Ingui is an artist and architect, as well as the president and a partner at Ingui Architecture, and a co-founder of both the Passive House Accelerator and Source 2050.

In this episode, we talk about the next big hurdle that Passive House needs to get over (hint: it's marketing :), the critical importance of product availability if you don't want your contractor to use something other than what you specified, and the 3 things that will either let us scale Passive House the way we truly need to, or not.
