1.5 tons in 6 months. this period is important. otherwise number doesn't mean much to me.
The annual carbon budget of each person is about 3 tons per person.
Thats the amount planet's biosphere can process divided by number of peoplle.
We changed our roof and cut CO2 emissions

Re: We changed our roof and cut CO2 emissions
#12It 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.

No it’s not. That’s a very normal temperature for our bedroom in the winter time. It probably depends where you’re from, in colder climates people are used to it.
Actually my experience is the opposite. In colder climates such as Russia, Finland I have seen room temperatures to be quite mild, above 20C for sure. However, in Italy in winter it is quite cold inside. Needless to say that thermal insulation is awful in IT.
Agreed, not sure what jb1991 refers to as colder climates. Countries with colder climates normally have decent indoor temperatures during winter. In Norway for example, you would be considered crazy to have anything less than 21-22C indoors.

#14They may be saving energy, but 17.2°C average temperature indoors is freezing.
Average UK indoor temperature is about 17.5c-18c apparently so hardly freezing. A bit chillier than I like in my office.
Personally in winter I heat my house to 14c as a minimum, 20c in the living room and office. Reason being I only need warmth if I'm sat down and not moving, so any higher and I start to get too hot.

I work in temps as low as 5 C and as high as 34 C in this old Dutch house attic. It's not at all pleasant, but there's no upgrading this rented place. It's not worth it for the owner as they will never recover their costs by increased rent.
So I wear 3-4 layers, including fingerless gloves and a hat. It looks ridiculous, but nobody sees me. And in summer, well... I don't wear much or anything. I at least put on a shirt for video calls :P.
Frankly, it sucks; and this is my last year here before I go nomad full-time.

I sit all day in front of the computer in something like that. Just use 60 s to put on two sweaters and woolen underwear and you will save money/the world. It's really weird to heat the whole house just to heat yourself.

Could it be that the outdoors being so cold increases radiation losses so you need a higher air temperature to compensate?
Personally I find if it's especially cold outside, I need to put the thermostat up to compensate.

That's insulation but insolation can also help with saving energy ;)
I'm guessing `insolation` turns you into a clean energy source. Can't imagine it's good for the immediate surroundings though.
Nah, insolation is fine, so long as you keep it below 1362 W/m2 or so.

Buildings like this in Paris are often so tightly packed together that windows in walls barely provide any light. Replacing the roof with a more standard one would necessitate giving up any daylight and having lights on all the time.

> in colder climates people are used to it
It's the other way around. Indoor temperature varying with the outdoor temperature is one of those weird things you experience when going abroad from your colder climate, at least in Europe.
