Passive Design Plugs into Solar on Green Roofs in Philly
October 28, 2025 @ 7:00 pm – 8:30 pm
Residential Solar is getting creative in Philadelphia. Join Ron Celentano as he hosts a virtual tour of four Passive House designed projects that incorporated Solar PV along with green (vegetative) roofs to achieve ultra-high energy efficiency, low environmental impact and ultra-low external energy consumption. Pennsylvania’s longest running and most deeply-embedded Solar-advocate will preface the virtual tour with an update on Solar PV installations and pending legislation in Pennsylvania. Let’s get aspirational in October!
