Re: Empire State forever!
I am impressed the Empire State Building made the list. Did you know it took 1year and 45 days to construct. It s built with limestone, granite, steel and brick. Brick is very energy efficient and with steel beats the world of glass buildings on heating and cooling energy usage.

Re: Empire State forever!
I agree, Susan! I would have thought that such an iconic old skyscraper would never be green-able, that buiiding green means building new construction. I wonder how the Flatiron or the Chrysler buildings fare in the world of LEED certification, for that matter. I've always heard it's very costly to retrofit a building for, say, improvded earthquake-withstanding status, and that often building from scratch is prefereable. But I suppose one is akin to the building's muscles and bones and the other, its respiratory system.

a Green "Energy Hog"?
Hey Kim: How did the BofA building - by far the least interesting and most traditional of the group - attain that LEED certification but still draw fire for being an energy hog? Is it a per capita thing, whereby even if a building consumes a lot of resources, it's still certifiable because of the large number of people it houses?

Re: Empire State forever!
Agreed! I've always loved the Empire State building, and it's great to hear that it is energy efficient too. "They don't all have to be soaring towers of glass," indeed.

Empire State forever!
There's something incredibly heartening that the Empire State Building made your list, Kim. That such an elegant old lady can still be up with the times is encouraging. Probably the quality of construction of the Empire State would be hard to duplicate these days, so the idea that it can be as energy efficient as its shiny neighbors speaks well to the versatility of green building. They don't all have to be soaring towers of glass.

Glass
Yes Kim, thats it. The first ever 'Curtain Wall' system (ie glass walls that are hung off floor plates rather than being load bearing) was built in 1850s in Liverpool called The Oreil Chambers. And has eveolved to the glass boxes we have today. If these buildings manage the solar radiation its not a problem energy wise but if they rely on artificial cooling then it defeats the object of going green. Many great example in Germany use a twin skin of glass to control the solar gain inside the building. Its an interesting area where building design is catching up with other tech areas.

Ugly? Beautiful?
My selection was driven partly by trying to find an interesting mix, partly by where I could get to, and I feel I ended up with some ugly buildings and some beautiful ones. That BoA tower is a grim modern monolith.  The Solaire condo building fits its setting beautifully.

Re: Glass and Green
I certainly share the impression that the use of glass in facades is much greater now than it was in early NYC skyscrapers.  Am I right in thinking that changes in materials have made it possible to create more and bigger windows without weakening large structures?

Glass and Green
Its interesting the number of green buildings which use glass facades. Glass is quite energy intensive, and the sun it lets in is half the problem that Air Con has to fix, which is why its good to see the Empire State Building on the list. I predict it uses a fraction of the energy to cool than the others.
