The major differences from just ordinary air-conditioning were that it was thrillingly more expensive, and involved a huge amount of sophisticated measuring and regulating equipment which was far better at knowing, moment by moment, what kind of air people wanted to breathe than mere people did.

What does 'did' stand for here?
Thanks.
Is it possible to substitute 'were' for 'did' without changing the meaning?
"[...] equipment which was far better at knowing, moment by moment, what kind of air people wanted to breathe than mere people were."
Thanks.
I think it's much better this way.

NOT A TEACHER
(1) Wow! May I just express my admiration and envy at your grasp of English grammar?
(2) Your post reminded me of something that I had read in the famous Fowler brothers'
1906 classic entitled The King's English (page 340 in the third edition):
"Do cannot represent be."
TheParser is right to note the Fowlers’ aversion to ‘do for be’ (continued in HW’s Modern English Usage, 1926 sub ‘do’ at 3b), but I think we all agree that this is a worthy rule-proving exception.
The only point I would make – and here I am not sure if I am agreeing or disagreeing with birdeen’s call – is that I think ‘did’ is, in this context, better than ‘were’. Both because of the sharpness of the repeated ‘d’ and because ‘did’ has a more active affect than the languid ‘were’ (which thanks to its half-rhyme with ‘mere’ would be even more lulling), I find that ‘did’ produces a nicely crisp ending to the deliberately convoluted sentence. (You could, I suppose, argue for ‘were’ on the ground that the sentence trickling away into near silence would leave a deliberate blankness in the reader’s mind, in which s/he could goggle at the inanity of it all, but I am not convinced.)
