Smart Thermostats In New Office Buildings--Carbon Dioxide Concerns
Posted on 5/19/23 at 9:20 am
Posted on 5/19/23 at 9:20 am
I moved into a new office building just two weeks ago. This morning I noticed for the first time the individual rooms are equipped with SMART THERMOSTATS which measure temperature, humidity, and CO2 levels.
The carbon dioxide level right now where I'm stationed is an unnerving 584 ppm! That seems unacceptably high.
Is anyone here familiar with the new CO2 indicators, and can provide input into what is a tolerable concentration of that gas?

That’s normal for CO2

I wouldn't be concerned until it was over 1,000 ppm.

Modern technology can measure CO2 levels inside and when they get high introduce more outside air into the building via the air conditioning system.

You should stop everyone from breathing

This is very concerning and will cause untold intra-office catastrophes in the future. I estimate that you have about 10 years to act before reaching the point of no return.

Too bad it doesn’t measure farts as well.

Look bro. I'll level with you. If you buy enough of my carbon credits, I'll move 100 ppm to outside the building so you can breathe easy. I'll need you to wear a rebreather and a diaper though (for the methane.)

Obtuse 1 is correct. Between 1000 and 2000 ppm people may begin to feel drowsy. 421 ppm is what the avg is outside. So I wouldn’t worry about 500 plus .

If the thermostat level bothers you get a paper bag and breathe into that. Then you won't be breathing any of that nasty room CO2.

its a energy saving feature.
you are required to have so many air changes (fresh air pumped into the building and old air exhausted) per hour based on max occupancy. Outside air is expensive to cool and dehumidify. On a Variable Air Volume (VAV) system like most newer offices there is a minimum CFM setting that is the OA requirement. but if no one is in the office then why spend money on air changes. CO2 is an alternate means under ASHRAE standards to set OA requirements.

At those levels you can expect a water cooler temp rise of .8 deg C over the next 15 years. If left unchecked your drinking water will be tepid in less than 9 decades.

That would include measurements of methane, H2S, and *gasp* smelly organosulfur compounds, in addition to nitrogen and CO2.
Will consult a chemical engineer to design such a device-- someone could make a fortune

That's worrisome enough. It was so much better back in the '50s when it was ~ 250 ppm and the climate worldwide was normal.

Lol, this has to be a weird troll. Seems pretty low for inside a building.

I'd rather see the methane PPM in a Chipotle.
