CIA Goes Green, Or So They Tell Us

The Central Intelligence Agency's new facilities in northern Virginia are going LEED, with a 22,000 square foot green roof, 40% savings in water by using low-flush toilets and waterless urinals, 21% savings in energy use by using occupancy sensors and energy efficient equipment, while improving air quality with 60% more fresh air.

The first office building, which opened its doors in 2007, earned LEED Silver certification, while the visitor center and central plant each earned LEED Gold certification. Details on what they did below the fold.

I'm all for saving water, but a "waterless urinal" does not sound like a pleasant peeing experience.

I wonder what a totally green roof would do for visibility from the air or orbit? The area is surrounded by trees, I imagine a green roof would make the whole complex mostly invisible from orbit, and very difficult to see from the air, especially at night.

A very good, basic list of things that should be included in any retrofit or new project.

The 21% energy savings is not particularly impressive. They ought to be able to achieve 25-30% without much difficulty.

There should be able to be substantial reductions in electricity needed for lighting.

If they use air-to-air heat exchangers they could reuse much of the heat from space conditioning that would otherwise be wasted. That heat could be used in air conditioning, to preheat water for process or washing needs, or stored in a reservoir for night time or cold weather heating needs.

In general, the complex is a suburban office park. In the middle of a wooded area. I suppose they should get some credit for rehabbing and conserving the embodied energy. Oh, wait, you say 'new'. But it looks a great deal like the existing complex...


That's quite a bank of heat exchangers in the foreground! - dumping expensive to obtain heat into the atmosphere.

Doesn't look like too many skylights on the main roof.

Certainly can't see any solar collectors. The main roof looks ideal for photovoltaic panels and hot water heaters. But I suppose that's too granola for this year...

We have the new waterless urinals in my building and they work surprisingly well.

jump to top Jon says:

get used to waterless urnials. They make complete sense, and the days of using water to flush pee(mostly water) were wasteful and are numbered.

jump to top gbrungra says:

jon That could be cooling for a data center.

jump to top Tim Russell says:

What he said!

This thread isn't big enough for 2 Jons. Especially when discussing the splendors of waterless urinals...

jump to top jon says:

Spike - what does the water do for you in a urinal? I don't even flush when I use them...

jump to top Ross says:

"Doesn't look like too many skylights on the main roof."

This is the CIA headquarters...

don't look up.

jump to top Abe Lincoln says:

I'd hate to add to focus on the urinal, but I have to agree with spike, wouldn't all your urine splash all over you?!

jump to top Josh says:

do waterless urinal stink? or is better than those with one?

jump to top quickthinker [TypeKey Profile Page] says:

Waterless urinals work with a jelly like doughnut that contains the smell. If you've never seen a waterless urinal, you are either a lady or have never walked into bathrooms at airports and most buildings on the west coast.
