I don't have very detailed info for you, but I know the towers used a large basement chiller plant which used water from the Hudson. I've got some blue-prints which show where the chiller plant was located. This space was largely destroyed during the collapse of the towers.

Thanks for that but it's saying video unavailable?

They should have stuck with the cooling solution of the river water for the new tower instead of just the public areas it's a massive saving on electric not having to cool that water so much.

Fixed the video link.

I'm not really sure why they chose to scale back the central chiller plant in the new complex. They did rebuild one that utilized the Hudson river, but it only cools the underground spaces, such as the 9/11 Museum, PATH, and Westfield mall. I'd imagine they chose to have the buildings handle their own cooling needs for a few reasons, namely underground space is limited and the designs / plans for the new towers was not finalized, and therefore it would have been difficult to design the plant which was needed sooner for the museum. Also, the river gets pretty warm in the summer, so mechanical cooling is required. I think in the end, they chose to downside the chiller plant and rely more heavily on "energy efficient" mechanical cooling.

Here's some information on the new plant. (pdf). Here's another.

I found more info on the original chiller plant for you. The original plant consisted of 7, 7000 ton centrifuges, and 2, 2500 ton units. After the 1993 bombing, a second plant was added which houses 5, 2500 ton units for a total capacity of 64,000 tons. The new plant only has a capacity of 20,000 tons. Check pages 8-13 (pdf).

Video still not working maybe it's cos I am in the U.K.?

I know why they scaled it back - it's because the more water they suck through the more fish and eggs can be damaged and stick against the filters.

Read an article on it.

So the environmentalists got their hands in the pie? Makes sense. Sorry the video won't play. It's titled "WTC: Operations-Control Center/Refrigeration Plan/Elevators/Power Supply/Window Washing" uploaded by WTCClips and is 11:01 long. Maybe you can find it on google.

Thumbs up Help - looking for image

Hi everyone,
I'm seeking a particular image of the WTC towers. I'll do my best do describe it -

The photo is of a person, a woman maybe, in an indoor swimming pool. The pool appears to be inside a skyscraper. The sun is setting and you can see the WTC towers off in the distance, but they are quite a prominent feature.

I'm desperate to find this photograph and I'm pretty sure I've seen it somewhere in one of skyscraper pages threads.

Any thoughts?

Thanks! =)

^^^^My guess is the image you seek is in this actual thread. I recall a section where the twin towers were featured in movies over the years. There are numerous still photos there.

For those aficionados of the twin towers, Les Robertson's book comes out in April. The table of contents lists a 58 page section devoted to the WTC.
