Passive House Podcast co-host Zack Semke interviews Shannon Pendleton, principal of Sanderson Sustainable Design and co-host of Passive House Accelerator Construction Tech. Shannon shares about her practice and how the Passive House approach has shaped it, the recent history of green building community building in Philadelphia, and the potential for an open-source approach to sharing building models (aka "digital twins") to help accelerate the transition to Passive House and high performance building.
