“...sophisticated ventilation system...”

AKA: random tunnels
With digitally printed materials it may be possible to enhance ventilation without added energy and I find this an interesting area of study. Problem is the environmental cultists will use this and anything like it to mandate unproven, expensive, and unrealistic building methods.
During the warm 7 or so months out of the year that I'm trying to cool the house, I direct the cold air byproduct from the water heater into an air receiver. That air receiver is almost always drawing in air, even if it's at low speed (a property of the variable speed air handler). Because that cool air is distributed through the house, my variable speed heat pump HVAC can operate in low speed mode for a couple of hours longer in the day (no need to kick into higher gear to work hard to keep the house cool if the air is already somewhat cooled by the water heater). Last but not least, the water heater itself operates more efficiently by virtue of the fact that the air intake vent of the water heater is ducted to draw air in from the attic above it (air that's usually pretty warm).
So the free heat from the attic is used to make the water heater operate more efficiently, then the free cold air from the water heater is used to make the home HVAC operate more efficiently (when keeping the home cool). When winter comes I flip a couple of duct levers by the water heater and force the cold air byproduct from the water heater to blow up into the attic (away from our living quarters while I'm trying to keep the house warm).
It's embarrassing that I didn't think to do this as soon as I heard about hybrid water heaters.
They want us to eat bugs, so if we live in termite mounds, our food will be right there.
I doubt that. With the consumption of all that fiber, there's got to be a few cases of cheese being cut.
There is no such thing as climate friendly AC. This is a term the creeps and liars use to guilt you into using existing tech. If they succeed then the formerly climate friendly AC becomes regular AC and they begin inveighing THAT . Rinse repeat.
Used to call them ‘cooling towers’
It’ll have to be extraordinarily “efficient” to make any difference when it’s 115 degrees in AZ.
I’m sorry, but what works in Sweden isn’t going to cut in Houston in August.
University professors discover fire can be used for heat!
In the time before air conditioning building were designed with airflow in mind. See former AT&T building at 32 Avenue of Americas, central staircase with opening vents on top of building. Teddy Roosevelt mansion (IE: Sagamore Hill)in Oyster Bay, central staircase with skylight at top.
” Termite mounds have a sophisticated ventilation system “
No they don’t.
I built my first house in 1984. Had a full daylight basement and two sides were 12” concrete, capped block. I’d always thought that if I could have had the time and money to put a ventilation duct system that passed air through the inner cavities would be cooled significantly.
I say BS! I built a house in SE Michigan in the 70s, thinking the same. used Hot water baseboard heating which cannot be made for cooling. The theory was that it is very rare in Michigan that it stays uncomfortably hot all night. I had a well- planned attic fan powered ventilation system to pull in the cool night air. Thad did work, but the problem was that it also pulled in the night time humidity. The house got uncomfortably humid every night and very uncomfortable. You can't be comfortable on hot humid days with just ventilation.
