Announcing The “Building Performance Interactive” Miniseries

Passive House Accelerator is launching Building Performance Interactive, an 8-part monthly virtual miniseries, on October 28 at 2 pm BST (9 am ET).

About Building Performance Interactive

The program was developed as part of a collaboration with the Accelerator and Hugh Whiriskey of Partel, who saw a need for more interactive programming to share lessons learned and best practices from the explosion of Passive House projects happening close to our original markets. “It started with a strong determination to support the transformation of the low-carbon building sector towards nZEB and Passive House through a new perspective, based on a collaborative approach,” Whiriskey said.

Format of BPI – virtual miniseries

Building Performance Interactive (BPI) – Design it. Shape it. Build it.  will be virtual and free to attend, focused on inclusivity, collaboration, and the elevation of high-performance building as its guiding principles. Episodes will provide a platform for audiences in continental Europe, Ireland, and the United Kingdom to learn about Passive House design principles, nZEB (nearly zero energy building) techniques, and other high-performance building methodologies that can help ensure compliance with the increasingly rigorous standards and policy goals of governments throughout the UK, Ireland, and Europe.

Each episode will be 60 minutes comprising of live learning sessions featuring informative video and technical presentations, case studies, roundtable, and opportunities for Q&A discussion.


Hugh Whiriskey will serve as one of the three co-hosts of the series, along with Mike Jacob and Ben Adam-Smith. Whiriskey is the Founder and Technical Director of Partel, with a strong background in low-energy construction, sustainable design, building physics, and technical product training.  Jacob is a Reading-based chartered construction manager and co-founder of KISS House, a custom-built home provider.
