Measuring CO2 emission


#1

Hello guys,

Does Ladybug Tools measure for CO2 emissions? If no, what is the best tool to measure the effect of a construction material on air quality and CO2 emission?
Also, how powerful or accurate is Butterfly to perform air quality analysis?

If you want to define the indoor CO2 concentration monitored by one or more sensors, you can consider the ladybug tools in order to realize something like this:

You can find more details here below:

Thank you for the reply, and sorry for my late return to the post.
Which component did you use to monitor CO2 concentration and IAQ level?

I think @Francesco661 might have meant that you can visualize physical sensor measurements with the use of LBTs, at least that’s how I understand it.

To actually calculate CO2 concentrations with OF you’d need a set up that is currently not supported in BF.

Kind regards,
Theodore.

Thank you @TheodorosGalanos for the clarification: I confirm that you can use LBTs to visualize physical sensor measurement but you can not use them to calculate CO2 concentrations with OF.
About the following question:

Which component did you use to monitor CO2 concentration and IAQ level?

You have to read the paragraphs 2.2 and 3.3.

Thank you for your reply @Francesco661 and @TheodorosGalanos

@Francesco661 where can I find these paragraphs, or which document you mean?
Also, can I measure CO2 emission of indoor constructions (e.g. walls, floor. etc.) along with CO2 release from occupants?

Why would the building materials emit CO2? It is also quite easy to calculate CO2 levels in well mixed rooms, you need outside CO2 level, room volume, internal air flow, internal CO2 emissions and a time step, usually one minute.

@MaxTillberg, thanks for the reply. I meant other airborne pollutants such as VOCs and formaldehyde emitted by materials not really CO2.
Can indoor CO2 concentration be measured in Ladybug tools? That’s all I need for now.
