This is my first time here in the Korean winter and I'm very shocked at how little energy is used for heating in public places.

The most striking example is the subway. Most stations are extremely cold, with very limited heating. Even inside subway cars the only source of heat that I have found is the heat from the subway chairs, making the fight for the subway chairs all more meaningful if you have been freezing outside of the subway station.

There are other examples too, but they are more private businesses such as restaurants and jimjillbangs. These businesses force their staff to work in extremely cold indoor temperatures to save money on energy, and they always have a few layers of clothing to protect themselves from the cold.

I am assuming this is all normal and also seen with public schools as well? (Hagwons?) In general I find the practice of conserving energy very good, and during the summer months I'm sure they are also very careful not to overuse the air-con. I know there's a lot of energy wasted here, but out of many countries I've been to I'd have to say Korea is extremely energy conscious.

and you've experienced a heated subway stations where exactly? because i never have and i've been to many different subways around the world. in fact, i'd go as far as to say all the commerce that happens in many stations along with the sheer number of people heat up many of the stations to a reasonable temperature. ever had to wait for a train at 4am in a new york winter? i know i'd much rather be waiting in gangnam station.

and as for the train cabs, where else do you expect the heaters to be? unlike air con, it makes sense for the heaters to be under the seats. that's where they are in almost all subways trains (hint: almost all subway trains are either french or japanese in design and build, not korean)

and korea, energy conscious? i guess you haven't seen all the garish neon signs everywhere.

don't worry, if it's one thing korea is pretty awful at, it is temperature regulation and consistency. it's always a random chance that any building here will be comfortable coming in from a hot or cold climate. and most of the time it has nothing to do with energy conservation.

If they were so energy conscious, they would learn how to properly insulate buildings so heat doesn't continually escape.

Heated subway stations is a world that I want to live in.

The problem is building insulation is terrible.

BS. Only recently have I seen more business owners trying to be more responsible with energy conserving; only, because it was mandated by the Government.

And they have to conserve energy because Korea couldn't run its Nuclear Power industry effectively, thus, because of this extremely cold winter it continues to dangle just above the energy reserve limit.

Last winter in Myeong-dong a lot of the shops would have their heaters running full blast but leave their doors wide open.

Like the previous posters have mentioned, Korea still has a lot to learn about insulating buildings. If it hasn't, it should be included in the building code for the construction of all new buildings.

Or at least close the doors.

When I saw the title of this thread, I thought it was sarcastic. Korea has gotten better in the last year (two at most), but there are still a lot of shops that leave their doors wide open to the street while blasting the air conditioning/heat, and I still hear stories of public schools leaving the windows open in the winter while blasting the heat to "let the bad air out" Rolling Eyes And if you really want to talk about conserving resources, I think those umbrella condoms they use all over the country when entering a building are a huge waste.

Actually you are right, I hadn't really thought about it but most of the subways I have been too during the winter were all in China and Taiwan. The metro in Shanghai, Beijing, and Taipei all seem to have some central heating, although I'm not 100% sure about Taipei.

Interesting, I wasn't aware of this to be honest.

From my understanding Neon lights are pretty energy efficient

Couldn't agree more, the summers and winters always feel like I can't get enough cold air or enough hot air inside buildings. But whenever I was in private homes or offices the temperature was always perfect, I always thought it was simply because businesses and the government don't want to pay extra money on energy.

I feel this way too... but what should they use? What we usually use is Fiber glass, but I think in East Asia it's avoided because of how humid it is here, allowing for mold growth. I'm sure there's other ways they can insulate their homes, but fiber glass has always been the easiest and safest solution. I'm not sure if it applies here. Anyone with a bit of experience in insulation care to share some insight?

Never understood why they like to do this, such a waste.

Hmmm, yeah it really is a big waste. Those bags are not easy to recycle. Although I was talking more about energy consumption rather than consumable goods.

In my personal opinion, yes and no. I feel that for some reason I just didn't see this very much at all (remember this is my first winter in Korea!). Even when i was in 명동 most of the people standing outside giving flyers were being heated by the those little radiator heaters that consume 1/3 the energy of a normal heater (still a lot but much better than nothing).

I did see an open window when i was inside the Dongguk 동국(東國) university campus computer lab, but I wouldn't say the heater was on full blast. Just maybe at 23 or 24C. I think full blast would be upwards of 26 to 27C right?

Interesting to see the view points here, I feel that Korea is being very energy conservative, but if they are really wasting their energy than that really sucks. Maybe I'm the only one that felt that besides the jimjillbang's and personal rooms, I never really feel warm.
