Why do skyscrapers leave the lights on at night when no one is around?

[simms]

I noticed in my downtown core on a Friday night all the big banks leave their lights on in the building, on all 50-75ish floors.

Why not turn off the lights like in your house?

They also got lights on the top of buildings to avoid that aswell.

Sometimes people have to work late, spend the night at the office etc...

Because it looks cool? Duh!

 

[RichUK]

so they can boast on how much they spend on their electricity bill

 

[Shlong]

Aesthetics, a building in Hong Kong costs around $30,000 per night for the lighting. They were gonna turn it off earlier but the people & tourists loved it so much they decided to just leave it on.

If nobody's truly around, how do you know they leave their lights on?

 

[EyeMWing]

Because there are 3 shifts many places.

$30,000 / 6 cents per kwh / .1kw (per bulb) = 5 million bulbs. Somehow, I doubt there are THAT many 100watt lightbulbs in even the biggest skyscraper.

Um, it's this building: http://www.skyscraperpicture.com/thecenter.htm 9000 Neon Tubes. I've got the $30,000 a night figure from a skyscraper enthusiast show on the BBC.

Mental note: switch lights off before going to bed.

 

[blahblah99]

To brag that they got the highest building..

but won't lights actually attract pilots who wishes to ream buildings? Pilots know what the minimum altitudes are allowed per given area. They also have maps that show exactly where high altitude antennas and structures are so it's very unlikely a plane would hit a building under normal psychological flight conditions. heh.

A waste of breath, most use fluorescent tubing... figure out the number of floors, and amount of square feet , and then add about 2 fluorescent bulbs for every 16-20 square feet

EDIT: and I believe there are still bout 24 hours in the day? so that would make it 208,000 100 watt bulbs, if your cost per kwh and usage are correct?

So they spend $10.95m a year on lighting a building so people can go "ooooh" and "aaaah"

Well the reasoning was the lighting was what made the building famous. People liked it & the tenants in the building pay an even more premium because they're living in such a famous building. So they thought the money spent on the lighting they'll get a bigger return then what they would've with just regular advertising.

Guess you've never flown in a small plane under VFR.......Visual Flight Rules. Yes, they even fly at night wiht VFR instead of IFR.....Instrument Flight Rules. Many, many small plane pilots don't carry highly detailed maps that you describe. Heck, during the day, many have rather "crude" maps and fly following interstates and the like.
