Passive House buildings go hand-in-hand with on-site generation and electrification, but what happens when you have code-required emergency power backup? The Kenzi tackled the wicked problem of designing, pricing, and permitting the first all-electric building above four floors in the City of Boston. We will dive into the nitty gritty of design, funding, and procurement, reveal our strategy for Boston Fire Department concerns, and discuss what code language we leaned on to pull it all together. The session will share why the owner and design team felt this seemingly insurmountable task was necessary to achieve on this age-restricted affordable housing project in Roxbury, MA.
