Reuters – March 14, 2024: There will be no air conditioning in the athletes’ rooms at Paris 2024, which has pledged to host the “greenest ever” Games. … Paris mayor Anne Hidalgo told those nations planning on installing air conditioning at the athletes’ village to “trust the science” instead… With climate scientists warning that global warming has produced more extreme weather patterns in much of the world, organisers of Paris 2024 have said they want to halve the carbon footprint compared with the Rio 2016 and London 2012 Summer Games. “I think we have to trust science on two counts. The first is what scientists are telling us about the fact that we are on the brink of a precipice. Everyone, including the athletes, must be aware of this,” said Hidalgo. “And secondly, we have to trust the scientists when they help us to construct buildings in a sober way that allows us to make do without air conditioning.” ..
Yet, the Olympic Committees from Australia, Brazil, Canada and Norway are among those who believe it will not be enough.
“Our clear wish is that there should be air-conditioning in all rooms,” the Norwegian Committee told Reuters, with Brazil saying “the heat forecast” made it “necessary to invest in renting air-conditioning units for the entire delegation”.

Allow only AC in very limited circumstances: “It will be on a case-by-case basis, and for health and safety of the athletes,” Michaud said, adding that ventilators vaporizing water droplets could be installed instead of traditional air conditioning units.

Modeling suggests that room temperatures during a heat wave would be 82°F (!)
My goodness, can you imagine competing as a world class athelete and then coming back to recuperate in your room that’s baking > 80°F
Insane risk for heat exhaustion.https://t.co/w7QhVbufiJ

The Paris Olympics is going underground to find a way to keep athletes cool at the 2024 Games without air conditioners.
Organizers are planning to use a water-cooling system under the Athletes Village — much like the one that has helped the Louvre Museum cope with the sweltering heat that broke records last year — to keep temperatures in check for the Olympians and Paralympians who stay there.
The decision is part of the organizing committee’s goal to cut the carbon footprint of the Paris Games by half and stage the most sustainable Olympics to date by installing a special technology to use natural sources to keep everyone cool even during a potential heat wave.
“I want the Paris Games to be exemplary from an environmental point of view,” said Paris Mayor Anne Hidalgo, who has resolved to tackle climate change with an ambitious action plan that aims to drastically reduce greenhouse gas emissions and make the City of Lights carbon neutral by 2050.
Compared to a conventional project, the carbon impact will be reduced by 45% for the Athletes Village during the construction phase and over the entire Olympic cycle, she said.
For two months between July and September 2024, the Athletes Village north of Paris will host 15,600 athletes and sports officials during the Olympics and 9,000 athletes and their supporting teams during the Paralympics. After the games, the 50-hectare (125-acre) site next to the River Seine in the popular district of Seine-Saint-Denis will become a zero-carbon, eco-friendly residential and commercial neighborhood with 6,000 new inhabitants — the first ones moving in as soon as 2025.
In anticipation of hot weather, organizers have been studying heatwaves block by block in the Athletes Village. They have simulated conditions in the parts of the accommodation most exposed to the sun and have tested the effectiveness of the cooling system with an objective to keep the indoor temperature between 23 and 26 degrees Celsius (73 and 79 degrees Fahrenheit).
The geothermal energy system will ensure that the temperature in the athlete apartments in the Seine-Saint-Denis suburb does not rise above 26 degrees Celsius (79 degrees Fahrenheit) at night, including during a potential a heat wave, said Laurent Michaud, the director of the Olympic and Paralympic Villages.
He said organizers have conducted tests in rooms that are located on the highest floors of the residences and are facing south and exposed to direct sun on two sides. They also considered directions of winds in the region and the water temperature in the Seine. They have worked closely with France’s national weather agency to develop temperature forecasts.
“Despite outdoor temperatures reaching 41 degrees Celsius (106 degrees Fahrenheit), we had temperatures at 28 degrees (82 degrees Fahrenheit) in most of these rooms,” Michaud told The Associated Press, detailing the results of a heatwave simulation. “In other rooms, we clearly had lower temperatures.”
In addition to the underfloor cooling, the insulation built into the buildings will enable residents to keep the cold obtained during the night throughout the day, Michaud said. To keep the coolness inside, the athletes will have to follow some basic rules, he added, including making sure the window blinds are shut during the day.
Laurent Monnet, who is in charge of the green transition at Saint-Denis City Hall, Paris’ northern suburb where the main Olympic Village will be located, said all rooms should be 6 degrees Celsius (11 degrees Fahrenheit) cooler than the outside temperature, without an AC unit. Although some Olympic hopefuls have already expressed concern about the lack of air conditioning, Monnet said athletes should adapt and help contribute to fight against climate change.
“We need athletes to set an example when they use the buildings,” Monnet said. “We can build the most virtuous village we want, it is also the use that will be made of it that will weigh on our carbon footprint.”
Eliud Kipchoge, a two-time Olympic champion and marathon world record holder, endorsed the Paris sustainability plan. The Kenyan is one the sport’s most vocal proponents of environmental justice and has repeatedly sounded the alarm on climate change and the impact of global warming.
“It’s a good thought, because we all need to reduce our carbon,” Kipchoge said in an interview with the AP.
He called on fellow athletes to help combat climate change by reducing their carbon impact during competition, training and their lives in general because “we are all going to go through the same scenario.”
Paris organizers have been in touch with national Olympic committees and said they will have the option of setting up their own AC units in specific cases and on condition that the devices comply with the organizing committee’s technical criteria.
Most national Olympic officials have responded to the plans to keep their athletes cool during the Paris Games with a wait-and-see attitude. Some Olympic officials are not excluding bringing their own air conditioners to France — or paying for one on the spot — depending on the weather at the time.
The Australian Olympic Committee said it will keep an eye on the weather patterns in Paris over the coming year to ensure “the optimal high-performance environment for our athletes, including heat and humidity mitigation that may be required.”
Michaud, the director of the Olympic Village, said organizers want to be kind to the environment, but not endanger the health of athletes. Some athletes, especially in Paralympic events, have difficulty regulating their body’s core temperature and if they reside in rooms in which it proves impossible to keep at 26 degrees Celsius (79 degrees Fahrenheit) at night, national delegations will be able to install a portable AC system.
“It will be on a case-by-case basis, and for health and safety of the athletes,” Michaud said, adding that ventilators vaporizing water droplets could be installed instead of traditional air conditioning units.
Hidalgo, the Paris mayor, is adamantly against turning next year’s event into the bring-your-own-air-conditioning Olympics — health exceptions aside.
“I can assure you that we will not change course and that there will be no changes to the construction program of the village regarding air conditioning,” Hidalgo said.
Regarding the option of organizers providing national teams with an additional cooling mechanism, she said: “I am not in favor of it. We must be consistent with our objectives.”
Copying a third world sh!t hole is progressive?
The mayor could reduce the CO2 by holding her breath…
What are the odds of the members of the French government going without air-conditioning this coming summer?
While citizens’ cars are made illegal at an increasing rate, during the Conseil des ministres, the cars of the members of government are during their diesel engines just to keep the air conditioning running!
(They admitted they need to make some effort though.)
Crickets about crickets on the athletes’ dining hall menu.
Gosh, no air-con in a temperate region. Oh the humanity!
It’s not Mexico or New Mexico. Just make sure the windows open.
Zero upvotes for making a big virtue signal out of not installing something that’s not needed.
Of course now I’ve posted that I remember that here, across “La Manche” as the French might call it, the Met Office puts out heatwave alerts when the temperature is forecast to exceed room temperature.
Heat is only measured at airports, in France too.
And outside Pharmacists which was why people were able send photos of the true outside temps in Spain and Greece that were 10C lower than the temperature that the Met office/BBC/WEF were trying to get away with.
I had some Parisian telling me last summer that his flat was unbearable without a fan and because of the >40°C temp.
I didn’t care enough to explain her that with a T>bodyT, a fan would have made it worse not better.
And air conditioning is not really common in europe anyways.
Why not tell what Europeans do use – particularly in the Veneto, Trentino, Lombardia, Piedmont etc etc?
Have a look at Southern France…
Not in private homes, but elsewhere quite commonplace.
Historically, there was way too much aircon in French public building. Many civil servant complained about the cold places!
Nowadays, not so much.
But it changed very recently.
Historical significance… that is the main reason there is not much air-con in Paris.
That and the French being very strange people who think the breeze from an air-conditioner can cause health issues….. The dreaded “Courant d’air”
Also the very strange froggies are scared of the equally dreaded “Choc Thermic”.. the change in temperature as you go from hot outside into an air-conditioned room.
The French are very strange people…. with a macaroon as their president.
legionnaires disease.
and yes the sudden temp from idiotically cold aircon to outside really can make people crook/keel over. lawn bowlers in aus tend to do that in summer. cold clubhouse stinking hot lawns
BS
Even in Poland temperatures exceed 40C
Most Spanish homes have air conditioning
Etc, etc, etc
You clearly know zero about European homes
Redge let me fix that for you
You clearly know zero about
European homes… anything“Gosh, no air-con in a temperate region. Oh the humanity! It’s not Mexico or New Mexico. Just make sure the windows open.”
I live in southern BC (Canada), and the temperature in my area in Jul/Aug is usually in the 30C (86F) to 40C (104F) range.
Having lived here for 20 years, both with and without AC, I can unequivocally state that if the temp inside is 28C during the day, that means the walls are 28C, not just the air. Opening the windows at night doesn’t cool the walls, and it doesn’t cool the air enough either. Also, the average humidity in Paris in July and August is 70%, which makes 28C (82F) feel like 30C (86F). Trust me when I say, it’s too hot to sleep.
On an average how many days annually was an individual in southern BC unable to sleep because of the heat prior to 1960? How many consecutive days could such a situation endure? When it finally cooled off were most of the people nodding off at work and driving off the road with closed eyes?
Why not ask about the 1930s dust bowl times, when there were no ACs and people just had to deal with it?
Yes, prior to the 60s almost everyone had NO AC for their homes.
Of course then, EVERYONE in a town had similar sleeping experiences and a shared suffering.
NOW leftists want people to return to the pre 1960s suffering.
So actually, what was your point?
Men were men and women were women back then – and the gays did their thing
Thanks, Drake. Your response to GC is bang-on.
When the third-worlders decide to start running the show in BC all they’ll need to do is pinch off the lines to your AC. As I remember over the hill in Alberta few had AC and everybody got along just fine. You’re a wimp.
We don’t need third-worlders to run the show in BC to have bad government – we already have it with the provincial NDP.
You go ahead and try to sleep in 40+C weather without AC. I prefer to use my head: close the heat-blocking curtains during the day, and use the tech available to make sleeping comfortably possible at night.
Leftist, leftists and more leftists! It’s pretty likely that even the leftists make use of air conditioners, especially in their automobiles. Wouldn’t do to just open a window a crack and let the breeze go through the hoopie. It’s obvious that the mayorette is making a political statement so the best reaction would be to ignore it, especially in that affects a few pampered athletes on a free trip that could lead to ephemeral fame and fortune and no one else. The excitement here in leftophobia land over this idiotic policy is very amusing.
You can be the first to go without any post-1960s technology. Start with medicine, transportation, the internet … and of course A/C.
Luxuries become necessities in the land of sissies.
When you became a Luddite did you have to register with the county clerk?
The current order of importance is this: !. Comfort 2. Convenience 3. Amusement 4. Safety. Everything else is below 19 on the list. No wonder the west gets its butt kicked every time it gets into a hassle with the primitives. The Anglos are so worried about running out of anti-perspirant that they forget to clean their rifles and charge their drone batteries. They are obsessed with maintaining an artificial personal environment that stays the same at all times. That’s one of the ideals that’s led to existential climate anxiety, the same amount of rain should fall every year, the same amount of snow, temperatures must be the same at a given time in a given location every year or we’ll be uncomfortable. Get a life.
agree I havent ever had aircon, a fan is the most. obviously better in thick stone walled old home over present weatherboard with only roof insulation. but while uncomfortable its not the end of the world its a few days here n there and night open the place up and water outside to induce cooling
No electricity for you!
My my what a smarmy jerk you are who doesn’t have empathy for others who are weaker, older or just sick gets overcome by heat.
It is YOU who needs to have empathy surgically attached to your shrunken heart.
Ever been to Paris? It gets very warm because – well… it’s a city and cities even in temperate zones get hot. I spent a week there in Summer attending a congress. The hotel I was allocated had no air-con and was like a bake house.
Please do some research before posting. Thousands of people died in France in the last heat wave because they did not have air conditioning.
(A) I don’t need to do any research. I used to live in France. And (B) why single out AC, of all the interventions that could prolong a dying person’s life? Medical professionals, families, and even the dying themselves routinely prefer not to intervene for the sake of delaying the inevitable. I strongly disbelieve that healthy people died of the heat in Paris.
AC in nursing homes and hospitals is not the same as AC in an atheletes’ village. Olympians are rudely healthy.
All that said, I have no beef with AC. If it was on in my Parisian hotel room I wouldn’t rush to turn it off. It’s nice enough. Making a big fuss of not installing it is pure virtue signalling and deserves to be derided.
Yes.. NOT installing it IS pure virtue-seeking and should be mocked and ridiculed.
Apologies in advance, but you just got really unlucky …
I happen to be based in a “banlieue sud” of Paris, and updated the attached graph last autumn following the “Indian summer” in the first half of September.
NB : These are temperatures in the shade. Going out in “42°C temperatures” in direct sunlight, as I did briefly in July 2019 crossing roads on the way to the supermartket, was a very uncomfortable experience !
The “thousands of people died” heatwave was in 2003 (the black line from August 3rd to 13th.
“Thousands” died because it was the most severe heatwave in living memory … 1947 was a long time ago … and happened just after many Parisians had left their elderly relatives in Paris while they went on holiday for 3 (or 4 …) weeks.
_ _ _ _ _ _
“The last” heat wave was in 2020, from the 6th to the 12th of August, and was subject to the (by then) boringly monotonous “Alerte canicule ! ! !” messages that are now broadcast on French TV every time temperatures go above 25°C, along with exhortations to “check on your elderly neighbours”.
Note that in August of 2020, however, a few tens (/ hundreds ?) of “heat related deaths” would have been completely overwhelmed by COVID numbers.
Since 2003 whenever temperatures go above 35°C every evening TV news program starts with reporting from old people’s homes … “EHPADs” in France … with cameras closely filming residents “happily” accepting glasses of water from the “attentive” carers.
People, and countries, adapt to extreme events … go figure !
Considering that the “death count” from either CoViD OR heat waves is highly suspect – that proves very little. Quite a few were probably neither.
old? frail? and didnt know how to use windows doors and breezes? of course living in anthills doesnt help
Short memory. They had multiple deaths a few years ago in a heatwave when a few of their nuke plants were shut down
I was in Paris probably 25 years ago, and on three days in a row where it reached above 35ºC
The Paris record is 41.9ºC..
Obviously they are trying desperately to cause heat stroke deaths among the athletes…
They will blame it on “climate” rather than stupidity.
Olympic athletes could face a tough opponent: Brutal Paris heat (nbcnews.com)
What do you mean here? I thought climate change was making temperate regions a lot hotter, and aren’t the alarmists constantly warning about an increasing number of heat waves that will affect western Europe unless it renounces fossil fuels? Let’s see how all the tourists react if the hotels, restaurants and other venues decide to deprive them of A/C. Maybe there was no A/C during the last time Paris hosted the Games, but that was in 1924. This is the 21st Century.
Does climate change mean that heatwaves will be more common and more intense or does it not?
Easy for someone who’s not competing at the edge of human ability to say A/C isn’t needed.
I certainly trust Eliud Kipchoge’s knowledge of climate change. After all he did graduate from secondary school in Kenya.
I have a good friend whose daughter is on the US National Swim Team. I am sure they will be thrilled to read this.
Hidalgo is much like our own Khan
[in]Seine
The mayor of Paris is listening to climate scientists who say the Earth is “on the brink of a prescipice,” and athletes should make sacrifices.
Of course, if the Earth really was on the brink of a precipice, the Olympic Games should’t be held at all. But it isn’t so they are held, but athletes must suffer while somebody tries for a gold medal in virtue signalling.
“while somebody tries for a gold medal in virtue signalling”
Yes, as if this gesture will have any effect at all on the Earth’s climate or the current situation. The mayor is just virtue signalling and probably thinks she is setting a good example.
The mayor should “trust, but verify” when it comes to alarmist climate scientists and their dire claims of CO2 doom. If she did, she wouldn’t be shutting off the airconditioning.
Western leftist politicians have a serious lack of critical thinking. Maybe that is part of being a leftist and they can’t help themselves. If they were critical thinkers, they wouldn’t be leftists.
Meanwhile, the French and Parisian governments keep their ACs on full blast.
Your last sentence describes the reason for most of our problems…right there with the observation that some ideas are so ludicrous that only an intellectual would believe them.
Perhaps the question should be
How much $$ does the mayor expect to save by not paying for AC electricity?
No, it’s how much $$ go into the pockets of her cronies for the alternative method – and how much gets stuffed into her brassiere as her cut.
Have Her Honor explain the tipping point caused by a 1°K (+) to the current approximately 288°K (+) average global temperature.
Where are all the trolls who repeatedly declare that there are no “responsible” climate scientists who are predicting an eminent climate disaster?
It of course depends on WHICH climate scientists she is listening to.
If it were up to me, I’d go with Lindzen, Happer, Curry, Spence, Christie et al, and stay cool after a day of competition.
There are no climate scientists (IPCC). Climatologists, yes, computer nerds, yes.
Yes…all those flights bringing athletes and assorted hangers on.
Maybe they could do a sort of remote zoom race? Syncronised timing from home countries?
Maybe a sailing ship themed transportation company will start up to take all the athletes and tourists to Paris in a sustainable fissile free way.
Notice that the temperatures forecast for individual rooms, etc. are based on models of outside temperatures and humidity and the efficiency of their rooms and air handling systems; no scale tests.
Trust a woman to make such a stupid decision about what a sufficiently cool temperature is. But why is everyone else going along with it?
She’s the boss
If it were my wife determining the settings the air would blow cold then hot, cold then hot, as her wonky metabolism wobbles about. Me, I’m just cold all the time.
If she was that concerned about climate change and the earth being on the precipice why in the world did they host the games? I mean, the Olympics or earth’s destruction…hmmmm.
Not even if all of France abides by those rules. And it does not.
Is there any limit to the depth of stupidity these people can reach?
Apparently not.
Being an international example of graft and corruption at the highest levels it’s no surprise that something like this should occur as an adjunct to the Olympic scam. The games were held at the French city twice before air conditioning even existed but nobody seems to have remembered that fact. Of course those were in the days when Arctic sea ice extended nearly to Calais.
It might be more impressive if Mayor Hidalgo banned the use of electric lights, which consume far more electricity that produces CO2 and raises the local temperature to unendurable levels. After all, the earliest Olympians competed without electricity at all and no international television coverage until Tokyo in 1964.
Ultimately, the issues says more about human society than anything else, that the developed world insists that living in a small temperature envelope is necessary for life to continue. Of course even now humans live in places like interior Alaska, temperature dropping as low as -50F and lower to 130F in Death Valley. Forbidding AC in Paris is, of course, virtual signifying in high heels and fishnet stockings but just the same the climate of Paris is among the most congenial in the world at any time. That’s one of the reasons people have lived there for many centuries even before the invention of AC.
41C (106F) at 70% humidity (average in Jul/Aug in Paris) is NOT “congenial.” It’s stinking HOT. It feels like 77C (171F).
And if the indoor temp is 28C (82.4F), it feels like 30.7C (87.2F).
.
106F and 70 percent humidity is some serious weather!
I didn’t know Paris got that hot. That sounds more like Oklahoma weather.
I usually stay inside under the airconditioner when it is that hot and humid. That’s probably a heat index of about 115F with that high humidity.
High humidity can sneak up on you and tire you out quicker than low humidity, if you are outside working in it. Your body can’t cool itself as efficiently under high humidity conditions.
BWAHAHAHAHAHAHAHA!!!
your stupidity is on display here since the two previous SUMMER Olympic games held in France was in 1900 and 1924 when AC didn’t exist to be used affordably in buildings as that didn’t come along for a few more decades after 1924.
I recall the original Greek Olympics, 3000 years ago, we had no AC and thought nothing of it, of course we just jumped in the ocean to cool off.
I didn’t see you there, which end of the Stadium were you ??
FOI Request to UK Energy and Net Zero department:
Hi, Kindly let me have all of the information that the energy department holds which proves beyond reasonable doubt that the UK being Net Zero will influence the UK’s local temperature weather and climate?
Whatever?
It is still early in the week, but this may be the silliest idea we hear this week.
So no heating for the winter olympics is the next logical step. Will anyone turn up to compete?
I think she means carbon dioxide?
Something tells me that Mayor Hidalgo will not be suffering if the weather is warm.
Anyone who says carbon when they mean carbon dioxide is lazy or has an agenda or is lying.
Or has no clue what they are talking about.
Bingo
“It’s what everybody else says…”
That’s good enough for Anne.
As the society matron said after Nixon’s election: “How is that possible? Nobody I know voted for him.”
Unless they are talking about Red Chinese coal plant soot on the Arctic ice cap. Then they are being correct.
Underfloor cooling! What moron came up with that Idea.
I suppose the competitors can sleep on the floor.
Maybe the athletes can literally go underground to keep cool by sleeping in the Metro (subway). There would be a slight risk of being urinated on by vagrants who live there (most Paris subway stations have the odor of urine).
Long-term averages for temperatures in Paris in July and August: Daily Max 76 F / 24.4 C; Daily Min 58 F / 14.4 C. On average, the athletes can keep cool by simply opening their windows at night, closing them in the morning.
But if there is a heat wave during Olympic week, let the athletes sleep in an air-conditioned hotel. An athlete who couldn’t sleep the night before his/her event due to heat and humidity is not likely to perform as well the next day. If Madame le Maire (mayor) is worried about the carbon footprint, what about the CO2 emitted by planes used to transport foreign athletes to Paris?
Denying air conditioning to Olympic athletes will favor athletes from tropical countries, who are more accustomed to the heat.
About as useful as water radiators on the ceiling.
“The first is what scientists are telling us about the fact that we are on the brink of a precipice”
statements like that require a reference one can check.
From the above article:
“He said organizers have conducted tests in rooms that are located on the highest floors of the residences and are facing south and exposed to direct sun on two sides. They also considered directions of winds in the region and the water temperature in the Seine. They have worked closely with France’s national weather agency to develop temperature forecasts.”
Excuse me, but weren’t those “tests” carried out with the rest of any such residence building being UNOCCUPIED?
The total heat production of an “average” person at rest per hour is 58.2 x 1.8 = 104.76 = 105 watts
(source: https://ergo.human.cornell.edu/studentdownloads/DEA3500notes/Thermal/thcondnotes.html )
I suspect the metabolism of top notch athletes probably pushes their at-rest average heat dissipation up to around 120 watts.
So, if we assume one of these newly-constructed, room AC-deficit, athlete residences is 10 stories high and has 20 rooms per floor with 2 athletes per room, that’s housing for about 400 athletes. Multiply that by 120 watts per person and you are looking at something like 48 kW of power being generated internal to the building just from human body metabolism!
Also, if the athletes follow the dictum of “making sure the window blinds are shut during the day”, what about the heat load from the indoor lighting then needed for residents to be in those rooms during daylight hours? I’m betting that the aforementioned room temperature measurements were also conducted with all building windows having closed blinds but also with NO room lights being on at the time.
And then add to the waste heat dissipation from indoor lighting (including that used in hallways 24/7) the extra waste heat load produced by building elevators as well as by television sets, portable computers, and other personal electronics being used/charged by athletes in those rooms. All in all, you’re very likely having to continuously remove something like 100 kW of heat from an “average” newly-constructed and occupied Olympic village residence building.
That’s not going to be accomplished
easilyjust using the 5 °C (9 °F) delta-T available between the temperature of the Siene river water and the warm residence buildings. For the months of July and August, the average water temperature of the Seine River in Paris is likely to about 21 °C (ref: https://seatemperature.info/paris-water-temperature.html ) and yet the intent is to use this “natural, geothermal” resource to maintain new building temperatures below 26 °C while considering the above factors? Really???48 kW of power is 4.1472 GJ of energy per day.
I wonder how many mol of air is in those buildings.\
Specific heat being what it is, there will be a temperature rise from all those bodies at rest.
1000 mol per m^3. Estimate each room as 6m x 6m x 3m = ~ 1000 m^3 and 200 rooms = 2E5 m^3 = 2E8 mol.
Air is 0.0289 kg per mol. 200 rooms (2E8 mol) = 5.78 E6 kg.
Specific heat is 1 kJ/kg-K.
4.147200 E6 kJ. equates to an overall temperature rise of just under 1 degree, assuming circulation, etc.
So it is probable that the rooms will be warmer than estimated.
With athletes not immediately going into a coma and using the added power mentioned, it is more likely to be a 3 degree rise above the Paris estimate.
And what will they do will all the CO2 (>> 2000 ppm) exhaled by the athletes. I really hope they provide decent ventilation given no open windows.
SN4, you posted “1000 mol per m^3.”
Per standard scientific definition, one mole of any gas at STP is equal to 22.4 liters. There are 1000 liters in one cubic meter.Therefore, there are only 1000/22.4 = 44.6 moles of gas per m^3.
This alone introduces an error factor of 22 too low in your calculations.
You also posted “Estimate each room as 6m x 6m x 3m = ~ 1000 m^3.” However, 6*6*3 = 108 = ~100, NOT ~1000. That’s a separate error of a factor of 10 too high in your calculations.
I stopped at this point.
I was both too quick and trusted Google. Sorry about that.
Also, I used 24 hours, but it should have been ~12. Funny how all the errors cancel out. 22 too low, 10 too high, 2 too high.
I should write a climate computer model. All the errors cancel giving the right answer.
Well, that is the IPCC approach anyway.
Giving it another go….
Given 200 athletes resting generate 48KW per hour. = 2.07E9 J in 12 hours
Given rooms are 6m x 6m x 3m and 20×10 rooms = 21,600 m^3 volume of air
1 mol is 22.4 liters = 44.64 mol / m^3
Calculates to 9.64E5 mol in building (200 rooms)
Mass of air is 0.0289 kg / mol
Calculates to 2.79E4 kg air in building
Specific heat capacity of air = 1 kJ/kg/K
Calculates to 74.4 degrees K (or C) above starting temperature assuming no heat removal by walls, air flow, other heat sinks and ignores electricity use.
The walls will sink a lot of this energy. Concrete, for example, has a heat capacity of 0.920. Drywall (gypsum) is between 13.5 and 17.5 but at temperatures much higher (140 C to 170 C) than expected
Without doing a full analysis of the structure, primarily due to the unknowns of the construction, it is a safe conclusion that the rooms will be warmer than estimated.
Also, this does not account for the CO2 respiration which affects the specific heat capacity of air.
It’s a safe bet that the athletes won’t be sleeping all the time they are in their rooms.
She and her entire administration deserve all the mockery they get. This is nearly as demented as Jacinda Ardern’s antics in New Zealand during Covid.Scratch a leftist, find a petty, irrational tyrant.
“Scratch a leftist, find a petty, irrational tyrant.”
Radical leftists have a burning desire to control other people’s lives. It’s based on fear. They fear a lack of control, so they want to control everything, in order for them to feel safe.
Imagine how afraid Trump makes them. He is threatening to take away all their leftwing control. Trump is going to dash their socialist “paradise”. And the leftists are beside themselves with panic. They are losing control.
If its so important to reduce the carbon footprint, why not cancel the games? Brink of a precipice and all that…

Maybe fill the place with Swamp Coolers.
An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. … This can cool air using much less energy than refrigeration.

Well, as someone who has lived with swamp coolers for 38 years, they work when the outside humidity is low. In that case you get about 30 degrees F drop in the air temperature that the cooler pushes out. And the air is humid, which is desirable for arid desert conditions – I don’t have to run a humidifier in the warm part of the year. When we get some subtropical moisture pushing into our area, say dewpoint >45F, it’s just miserable without AC. So, not at all applicable for Paris.
Swamp coolers (I called them water coolers, in my youth) don’t help much when the temperatures get over 100 degrees F.
I remember an especially hot day one time when I was a kid, where I stood right in front of the water cooler and all it was blowing was hot air. No relief.
I think we got an airconditioner not long after that. Now that was a pleasant experience! Quiet *and* cool, no matter how hot it got outside.
Can work if the humidity is low enough, generally in desert or near desert conditions.
Goblin Valley State Park in Utah uses them to cool the yurts that you can rent for overnight stays. They are powered by batteries charged by solar panels (no electrical supply to the park was available, at least when we visited). When we were there, and it was about 105 degrees F outside, the inside of the yurt was maybe about 85-90. Far better than outside, but hardly comfortable.
They might provide a decent temp reduction for Paris, though like others have said, humidity would probably make them less useful there. Plus, they require electricity too, so almost certainly verboten, just like regular A/C.
