I'm guessing `insolation` turns you into a clean energy source. Can't imagine it's good for the immediate surroundings though.
Still better than immolation.
Did I miss the amortization of the CO2 emitted during the change?
To preface, I am not trying to nitpick here. I am generally curious. Is this a correct usage of amortization? https://www.merriam-webster.com/dictionary/amortization
One thing to point out is that yes, saving CO2 is grand, but this doesn't sell just how much more _comfortable_ decent insulation makes things. I live in a '30s UK semi detached. It had an air brick , a blocked up fire place and blown double glazing in each room. (barring two that were replaced) We had to re-render the place, as it was starting to fall off at the front, and the back was scarred from unfinished renova…
My parents also have a door to the attic for storage and heat leaks up through the un-insulated edge of the pull-down stairs door.
On YouTube Matt Risinger is a great resource for home repair and information. He tends to like expensive products but overall he explains main concepts well.

Remember that these figures include indirect emissions such as the ones made by the government on your behalf to maintain, for example, carbon expensive infrastructure. The roads are a big part of that in the US. American suburban car dependency needs to die.
The biggest energy expenditure and as a result CO2 emission source per person is food. You like having peaches in February in Michigan? You like having meat 7 days a week? Guess what: all the industrial agriculture and transportation of that meat from a thousand miles away nets you an energy expenditure of about 10kW 24/7. In theory the biggest lifestyle change you can make to save CO2 is to go vegan and buy local fo…
Do you have a source for this claim?
All I have read until now points to a majority of individual emissions associated with vehicle emissions and Energy usage for Heating/Cooling houses/offices. I am all for a vegetarian lifestyle for animal welfare sake but I feel this focus on Agricultural emissions is misleading or at least misreported.

Nah, insolation is fine, so long as you keep it below 1362 W/m2 or so.
If insulated well and air sealed a home would lose very little energy. But also you'd need a good air handling system to move and refresh the air.

Having insulation on the outside of your structure, and especially outside of your air/vapour barrier, is ideally where you want it (behind whatever cladding you're using):

It would have been interesting to also estimate how much CO2 would be reduced if instead of a glass roof they used a normal properly insulated roof. So we can see what is the CO2 cost of a stylish glass roof. Note: I suggest using underfloor heating, it should be more efficient with a glass roof, because there is less hot air to raise to the top of the house.
Why would there be less hot air if you set the same indoor temperature? Hot air will rise no matter what.

The interesting part of underfloor heating is that it is not the hot air that warms the room. It is the radiation from the floor. Smth like 10w/C/m2. And the heat profile in the room looks much better. For example https://www.researchgate.net/figure/An-example-of-vertical-t...
Unless you're losing heat through the floor I doubt that temperature difference between the floor and ceiling is accurate with a radiator system, perhaps if you measure it 30 minutes after you turn on the heat, but throughout the day the temperature should be mostly consistent throughout the room unless you're losing heat through the floor.
