Lucyna de Barbaro, Ph.D., and Ayres Freitas, Ph.D., are inviting GBA back to their Squirrel Hill Passive House Duplex for a second tour! This is a unique opportunity to see how this stringent energy building standard, with the goal of achieving building envelope air tightness of 0.6 air changes per hour at 50 Pascals, is being implemented. In addition, the project seeks National Green Building Standard ICC-700 Gold certification.

Join us on the tour, and you’ll get to sport one of GBA’s snazzy hard hats! For more information about the project, check out Lucyna de Barbaro’s Facebook page.

What is a Passive building? In short, it involves an extreme energy efficiency (targeting 60-70% energy use reduction) and performance verification that is proven through an air tightness test with rigorous passing standards. For more information, visit the Passive House Institute US (PHIUS) information page.


Lucyna de Barbaro, Ph.D., long-time environmentalist, activist, and member of Passive House Alliance US, served on the Board of Directors for the PHAUS Western PA Chapter (now PHWPA), and her husband, Ayres Freitas, Ph.D., is a Professor of Physics at the University of Pittsburgh. They are passionate advocates for improved building performance and experts on all things Passive House.

Members of Passive House Western Pennsylvania (PHWPA) may register for reduced price as Members of Partner Organization.

Please note: one half of the duplex is for sale and listed with Keller Williams Realty!
