Green summer Olympics ==> no AC

https://www.reuters.com/sports/trust-science-paris-mayor-tells-air-conditioning-fans-2024-03-14/
Temperatures are expected to soar again in the European summer, after setting records in 2023, but there will be no air conditioning in the athletes’ rooms at Paris 2024, which has pledged to host the “greenest ever” Games. Instead, buildings in the athletes’ village have been designed with a cooling system drawing water from underground, and facades orientated so they get little direct sun.

“This village was designed to avoid the need for air conditioning, even in very, very high temperatures, in order to maintain comfortable temperatures,” Hidalgo told Reuters on Wednesday…

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”. Australia’s Chef de Mission Anna Meares said they were “looking at portable air conditioners to offer the athletes should they choose to if it gets hot, if it’s uncomfortable”.

If they want to construct energy efficient buildings for the athletes’ village, then fine. I don’t have a problem with that. Efficiency is good. But the virtue signalling nonsense about hosting the “greenest ever” Olympics is a little silly.

France already has some of the cleanest electricity in Europe, and would continue to have that clean electricity even if they did install air conditioners in the athlete’s rooms. The only way the Olympics could be “greener” would be if they hosted the games in Stockholm or Oslo, because Sweden and Norway also have very clean electricity on a routine basis.

The Olympics will take place in late July and early August. In the month of August 2023, the following was France’s electricity generation mix-
Nuclear: 69%
Hydro: 9%
Wind: 8%
Solar: 7%
Biomass: 1%
Total clean electricity: ~95%

Fossil fuels and other dirty sources: ~5%
The large majority of the dirty fuels burned for electricity was natural gas, which is considered the cleanest of fossil fuels.

I think Mayor Hidalgo should reside in the Olympic Village for the duration of the events. Including sleeping there.

The absurdity is that instead of building the village properly, and installing efficient air conditioning, the teams are going to use horribly inefficient portable units that will be running 24/7 just to keep ahead of the heat. Meanwhile, they could have installed proper very efficient heat pump units up front.

It can also be noted that air conditioning is not as widespread in Europe as it is in the US.

From the link:
Unlike the U.S., European countries don’t rely on air conditioning to cope with high temperatures. Fewer than 10% of households in Europe owned air conditioners as of 2016, according to the International Energy Agency.

Do you know that for sure? In late July (when the Olympics are on) daily high temperatures average in the high 70s.

But in the event of a heatwave of 100 F temperatures the buildings are designed to remain in the mid 70s.

We Americans have (especially those who live in hot portions of the country it must be said) have trained ourselves to be complete pansies. If the indoor temperature isn’t within a degree or two of our desired target, we view it as impossibly uncomfortable.

On one hand, it seems like a triumph because these buildings don’t need AC at all. But on the other hand, in a worst case scenario the indoor temperature might theoretically be 75 instead of 72 like we like, so the Olympics are ruined.

Excerpt from the article -

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”.

Australia’s Chef de Mission Anna Meares said they were “looking at portable air conditioners to offer the athletes should they choose to if it gets hot, if it’s uncomfortable”.

The Canadian Olympic Committee told Reuters it had “implemented a number of heat mitigation strategies in Paris to complement the measures put in place by the Paris 2024 Organising Committee, including air conditioning units in some athlete rooms in case of extreme heat”.
