(but I take the bet that, like all wind brewers of your kind, you will never do anything concrete and will continue to talk about the forums about your genius misunderstood by the mass of ignoramuses that we are)
Another judgment and more moved! Indeed, concerning my achievements, excuse the little and tell me if you have made the tenth:
Starting from an old private and professional Walloon habitat of 1967m² (250), I made sure that it reached full BEPOS status since 2012: I gave it access (a first at least in Belgium) to full status. BEPOS: water including drinking water, electricity (heating via a geothermal heat pump, lighting, cooking, etc.). Among other innovations: recovery of shower waste water to supply three toilets.
Better than Passive and even Q-Zen, we as a couple have achieved BEPOS status (positive energy building) since 2012, for our old habitat (56 years old to date): no more consumption expenditure for water including drinking water, electricity, heating and even electric mobility.
The EPB score reaches the first level (A): 48 kWh/year per m² in electricity produced on site (12000 kWh for 250m²). He is also busy all day (private & professional). The orientation of the habitat is also optimal: in a circle and facing south, which benefits the main occupied rooms.
Electricity is produced on site by a photovoltaic tracker, heating is provided by a heat pump (horizontal geothermal energy) and water exclusively by harvesting filtered rainwater that is also made drinkable.
NB We have insulated the building in an economical and deliberately targeted way (double glazing, ceilings, thermal bridges, pipes, over-insulation of the boiler and the buffer tank of the heat pump, etc.)
All this, despite the fact that in 2010 the Walloon Region (Energy Window) and other experts firmly assured us that it was impossible to achieve what we were finally able to create two years later !
We thus erase each year the total gray footprint of at least 3 people (for two occupants)!
Our habitat has been selected by the ASBL APERe (Belgian Association for the Promotion of Renewable Energies, renamed Energie Commune and subsidized by the public authorities) "as an initiative with a promising future and creating sustainable energy" as part of their campaign of continuing education "Tomorrow is today".
The program ONPP (We are not pigeons – RTBF TV) devoted a report to it: (cf. https://www.rtbf.be/article/se-chauffer ... d=10152406)

NB Here are some opensource tips (continuous updates), some of which are new, which have allowed us to save (on all energy levels) several thousand euros per month, and without depriving us! (see https://www.retrouversonnord.be/autarcie.htm#DoIt)
For the rest, it's a life in strict voluntary simplicity, almost zero waste, advanced recycling, biodiversity (more than 140 flowering shrubs of different species planted:. https://www.retrouversonnord.be/fleursRSN.htm), care for fauna and flora, permaculture (which already allows 80% self-sufficiency in vegetables), no travel for long journeys. Three years ago we created a Walipini-type greenhouse (underground), which allows us to have certain vegetables out of season and without heating.
We recently planted a PAULOWNIA (ultra-fast growing tree) which produces 4 times more oxygen and absorbs 10 times more CO2.
I also made with my own hands a buried greenhouse (Walipini type) which allows me to have vegetables in low season
SO EXCUSE A LITTLE!
