Marc (architect) sends a detailed discussion of possible certifications. Linda and I want to make this house a resource for others to imagine how they might pursue net zero.  To that end, we need to establish its credibility. Marc suggests: LEED, GreenStar, Living Buidling Challenge, and then setting up the house for tours by architects and builders, like the Homes by Architects, MN Renewable Energy Tours, etc.  Amen!
