Gas by volume
Nitrogen (N2) 780,840 ppmv (78.084%)
Oxygen (O2) 209,460 ppmv (20.946%)
Argon (Ar) 9,340 ppmv (0.9340%)
Carbon Dioxide (CO2) is only 381 ppmv (0.0381%)
However, water vapour (H2O) (also a green house gas) varies between 1% and 4% *MUCH* more than CO2 - so why are we all so worried about CO2 causing global warming????
EDIT
Isn't it interesting how many people believe that CO2 is the third most common gas and are stating its volume at 1% - over 25 times its real value. It's amazing what a bit of negative publicity can do, isn't it? Poor old CO2! :-)

There are only two main gases in the air, oxygen and nitrogen.... You could class carbon dioxide but that is only 1%..... However, interestingly enough, even though there is only about 1% carbon dioxide in the air you can go anywhere you want in the world and you'll always get a reading of about 5%.... Why? Because wherever you've stood for more than a few seconds, (unless it's very windy), you own exhalation will have bumped up the percentage of the surrounding area by an average of 4%.... Useless info there huh :-)

Off the top of my head the three top gases in the air are
Nitrogen ~78%
Oxygen ~20%
Argon ~1%
carbon dioxide is relatively low amonts about 0.03%
but particulates take up larger percentages

It is really more a question of how well the new system is designed as well as to how well it will perform. Any heating system is done correctly will heat well. To me the other question is related to which will be the cheapest to operate. The housing association probably will want the system that is the cheapest to install rather than the one that is the more efficient in terms of operating costs. So the questions should revolve around what is the basis for the system design in terms of assumed temperatures, amount of insulation and amount of air infiltrations as well as the annual operating costs since I assume you get to pay that cost.

78% Nitrogen; 21% Oxygen and trace amounts of other gases and also water vapour.

Nitrgen (75%) oxygen, about 24 percent, Carbon dioxide, about 1 percent, the other gases-such as methane (farts) and xenon-are in miniscule amounts..

Nitrogen, Oxygen and Carbon Dioxide in that order.
