CO2 Unchanged

Postby alhashem90 » Mon Aug 19, 2019 9:02 pm

Hi,
I have placed CO2 of 400PPM in background concentration with other pollutants.
But in Leonardo all pollutants had different dispersion across my model while CO2 looked constant with the same 400PPM across the whole model !!
I have tried to search it or read about physical reasons, but I did not reach an explanation of why it would be stable even when placing different vegetation across the model.
Thanks

Tim

Hi,

It should definitely change within the model if you the model area features plants. Could you attach some screenshots?

Best regards,
Tim

HI Tim,
I have attached pictures for the Basic case with no greens at all, living wall with percentage of 50% of all facades and 50% trees of all areas.
The living wall did not change CO2 at all, while the 50% trees have slightly decreased the CO2 emission in some areas at human level which is not logical as well to find around 15mg/m3 decrease only out of 763mg/m3 !?
Similar findings happened for Particulate matters (PPM) as well but I did not attach pictures, so is there an explanation for it as well?
Thanks

Hi,

I'd say the CO² reduction caused by the trees looks fine.
Greening on facades do not yet reduce CO² amount as far as I can see that.

Best regards,
Tim

The living wall plant are a system of itself and - so far- do not interact with the CO2
