No… No its not
No, not at all… wow…
Geo-exchange
Chilled Water
Basically anything that is on in large buildings use water
No, it would be stupid to pull in 100% OA instead of recirculating.
Why the hell not! They’re Yahoo!, they can do ANYTHING!
Lol.
The climate was definitely a major factor in them coming here LZ. Every news conference they had talked about it.
They even ditched their plan to buy into the whole carbon credits scheme.
Damn it.
Well… If they are heating/cooling air, I will just assume it came from outside then. Thats where I get my air.

With its Lockport design, Yahoo is joining Google on the cutting-edge of energy efficiency by running a data center without chillers, which provide refrigerated water for cooling systems and are among the most energy-intensive components of a data center.
Plans filed today with the town of Lockport indicate that the Yahoo Computing Coops will be metal prefabricated structures measuring 120 feet by 60 feet. The company plans to use five of these structures in its Lockport complex. Each of the coops will have louvers built into the side of the building to allow cold air to enter the computing area. The complex is being laid out to take advantage of prevailing wind direction, which would blow directly into the louver system.
Sure sounds like outside air to me.
NO SNAP. THE NYSPEED DATA CENTER KNOW IT ALLS MIGHT NOT KNOW IT ALL :mamoru: :ohnoes:
EDIT:
And yes, it does raise questions about what they’re going to do on those rare 90+ degree WNY days, but I’m guessing when they’re building a 150 million dollar data center they took that into consideration and don’t need the geniuses of NYSpeed to help them with their HVAC plan.
well, I think there is confusion.
They are not necessarily going to pull the cold air from outside. It just makes it EASIER for the hvac to cool the place, when the building is already in cooler climates.
Cooling down the inside of a datacenter in Florida or somewhere else warm would cost an arm and a leg.
edit: just read what jays posted, disregard me
Exactly…I’m sure they are pulling air from outside in addition to their cooling systems.
You pull air in from the outside…condition it to adjust for the proper humidity and take containments out…
:gay3:
I’m curious what their entire setup is like…
hot aisle/cold aisle, sealed hot aisle, raised floors, in rack cooling…
Me too. I really want to see pictures of how this outside air cooling system works. I’m picturing these louvers that look like the back window of an 80’s Camaro with the prevailing wind blowing through and snow drifting around a rack of servers but obviously it’s a little more high tech than that.
Most DCs try to keep a constant humidity rate which makes this interesting…
If they use blades or some other form of dense computing it would also make this a lot harder.
See below :picard, they also use natural ventilation to keep plenum space cool (or attic space). Code states you can not use natural ventilation to condition any occupied space though. It is done for IAQ. Large difference. Design criteria for a server room is 65°DB/64°WB and an OA amount of .05 cfm/sq ft. The outside air will not be touching the servers directly, they could be touching heat exchangers though if the systems are water cooled.
EDIT: just read more of this thread, ugh…
:lol:
I don’t think some people understand the BTU cooling capacity that is needed…
Just pulling in outside air won’t work.
And I think a lot of people think they know what cutting edge is because they designed some low end office building or ran the Sabres website. 
wait wait wait
we can’t just open the windows and let the air flow free? fuck
lol
Yea what do I know…
Holy fuck there is a lot of retard in this thread.
Stick to being arm-chair mechanics and not arm-chair HVAC designers.
Please stop… especially while you are ahead
Thats good news for Western New York, 150million dollar project and 75 tech jobs that should pay good. :tup: Good luck to all you applicants.
