What exactly is a high performance home?

What exactly is a high-performance home? Chris Laumer-Giddens of Atlanta, GA-based Architecture & Design firm LG Squared talks about high performance and off-grid homes and what it takes to make a home more efficient, no matter how old (or new) it is. We also talk about the term "high performance" and the different meanings as it relates to home construction, home technology, materials, surfaces, and more. Chris also shares details of the "Leakiest house ever tested" project, a 1920's era home that's being renovated with the hopes of achieving Passive House Certification.
