April 20 noon-5 pm: We’ve made some good progress on Spring Green’s first net-zero energy home. Take a tour, snap some pictures, ask questions. You’ll see the skeleton structure and what double-stud walls and raised-heel roof trusses look like. Admire the views through the recently-installed windows and ask about their energy-efficiency backstory. Have a look at the still-to-be-trimmed-out galvalume standing seam roof. Find us one block north of the High School at 770 North Westmor Street. Bring the kids, stay for s’mores. For more information call or text Amber at 608-935-9020.
