Surprised there are people against this. Why punish the athletes? If anything it just brings more negative attention to Russia than if they weren’t allowed to compete at all.

“The USA is a third world country”

I think people forget the standard of living is just higher here. Someone in lower middle class/ poverty in the US generally has a better quality of living than most other countries. Not comparing apples to oranges until you look at something like this.

Im also not sure things like cost of living are included in this comparison

I think you are confused...people are electrifying but generally not for heat. Here is a good reference for heating power sources and pros/cons and why electric heat is less efficient. This is generally accepted among the HVAC industry and is not anything controversial.

Basically it boils down to gas burning hotter than an electric coil and getting more efficient heat transfer due to a higher temperature difference between the air you are trying to heat and the heat source.

I also don't think its controversial to suggest that there is variability in solar panel efficiency in different regions. I provided a link below that shows the difference. Someplace like Arizona where there is more direct sunlight for longer periods in the day will have a higher efficiency than Iceland where theres 5hrs of daylight in the winter and its overcast often.

The cost benefit analysis for someone in NY who uses more heat and has lower efficiency with their solar panels is completely different from someone who lives in Florida where there is a low heat load and plenty of sunlight.

Again, I am not sure what I am saying that is so controversial or shifting goal posts.

Thank you...this sounds like a construction manager that has a vague understanding of HVAC

To one point though servers are more consistent with their heat output and cooling is sized appropriately and generally runs consistently. An airport has more diversity and can rapidly swing from a large load to almost none. A larger volume of air can manage that more consistently.

But yes, mostly the other things

I live in NY and can assure you that electric heat is a rarity.

I am not saying its not physically possible...but its not nearly as cost effective. The calculation isn't the same. You require more solar panels to get the same amount of power due to less efficiency.

Also electric heat is 60% less efficient when producing heat (which is why its so rare). So you need to produce significantly more energy to get the same heating output. Its not a cost for 1kw solar to cost for 1kw gas comparison....its 3:1.

Someplace where there is little heating required and lots of sun will have a drastically different number than somewhere where its cold/dark.

It depends on what you are doing with it...powering lights and some electronics in Florida? Sure. Heating a house in NY in February? Not so much

These studies ignore too many variables

Yes that was my point. The original comment I replied to stated that you couldn’t use chilled water to locally control a gate’s temperature. But you can

You can have a localized HVAC system that uses chilled water…?

You are correct with your idea of more air = more consistent air temperature / smaller temperature swings….but your explanation is a little off

There are other reasons beyond HVAC such as sound, lighting, room for large signage, and just overall aesthetics.
