At the time, Grocoff and his wife Kelly were in the process of painstakingly renovating
a circa-1901 Folk Victorian home in Ann Arbor's Old West Side Historic District in Michigan in hopes of achieving net-zero energy status (a home that produces more energy than its inhabitants consume.) So, refreshingly, this home improvement talking head was really
practicing what he was preaching.
Several months have passed, and I’ve featured a few remarkable net-zero energy homes including new designs
from Michelle Kaufmann, the Colorado home
of Jeff Hohensee, and this ark-shaped oddity
. Well, now it looks like congratulations are in order as Grocoff’s uber-efficient labor of love has just been deemed a net-zero energy home.
At around 110 years old, Grocoff’s home is now officially the oldest net-zero energy home in America, the first ever net-zero energy home in the state of Michigan, and the first net-zero energy restoration to take place in a designated historic district.
Grocoff’s “Mission Zero” goal was officially reached when the Ann Arbor Historic District green lit the installation of a full-roof solar array on the home. According to Grocoff, the rooftop solar array will help his family stamp out $77,400 in energy costs over a 20-year span while bringing in $27,000 in renewable energy credits from the local utility company.
Grocoff estimates that in addition to providing all of the homes electric needs, the rooftop solar array can provide enough juice to power an electric car
for 10,000 miles per year.
In addition to the electricity-producing solar panels, Grocoff went about adding insulation, low-e windows, energy-efficient appliances and lighting fixtures, a geothermal cooling and heating system, an energy-recovery ventilator, and more to his drafty old home.
And as you can see, “Mission Zero” doesn’t look a thing like many of the super-efficient homes that I regularly feature … it’s just a charming, thoughtfully renovated older home. Explains
We have restored the house to the original condition and maintained its historic elements, meeting the strict preservation standards of the National Trust for Historic Preservation. This is not a gut rehab or a pre-recession McMansion remodel of an old house, this is an affordable and practical restoration that we hope is an example for others to follow.
This is an All-American folk-Victorian home with the classic front porch in a Norman Rockwell neighborhood. You would never know it was “green” if you didn’t see the solar panels on the roof.

(wish I was!) and spott Grocoff (he's a member of the U.S. Green Building Council) be sure to give him a high-five, fist bump, or a hearty congratulations.
