Zero Net Energy and the Changing Shape of
Architecture
Finegold Alexander + Associates Inc.Nexus Green Roundtable February 16, 2011
“A Zero Net Energy building is one
that is optimally efficient and,
over the course of a year,
generates energy onsite,
using clean renewable resources,
in a quantity equal to or greater than
the total amount of energy consumed onsite.”

“You build with stone, wood, cement;
You make houses, places:
That’s construction.(..)
Then suddenly you catch my heart,
I’m happy and I say: that’s beautiful.
That’s architecture.”
