back when I was able to work, part of my work requirements was designing Self-Sufficient / Zero Energy Homes both Newly built and Existing homes ( and Commercial / Public Bldgs )
I had to frequently stay on top of the industry/field by continuously taking refresher courses, obtaining certifications and attending Seminars....
My closest to a Zero-energy built home from the ground up was a 5800 sq ft 2 story home with a 3 car garage and over the garage gameroom.... with just (2) 2 ton split system heatpumps ( 18.9 SEER rating each ) , Closed Cell Foam, tankless water heaters..among other things we used (window design, roof material, etc...... I designed a home that was able to only cost the home owner $37 to $52 dollars amonth for total utility cost ( electricity/water consumption )..... this home had 2 Adults and 3 kids in the single digit yrs of age, located at Atlantic Beach, Jax, FL.. granted this was not zero energy, which is the holy grail that we strive for but we push ourselves to get as close to 0 energy as we can.....
My mentor, who helped in the pioneering of FSEC ( Florida Solar Energy Center- University of Central Florida ), and is a National Proctor for the ACCA.....designed/built a renovated home here in NC that was around 2200 sq ft and the monthly energy cost was around $28 to $29 a month
here is a video that might interest some of you who are interested:
