"Green Data Centre,
Eco-Friendly Data Centre Promises Windfall For HP Clients", 02 Feb 2009
"By 2011, the average UK data centre is expected to spend around ￡11m
($15.33m) a year on cooling IT systems, equipment and plant rooms."
"Wynyard is able to reduce the cost of cooling in its facility through
a number of design considerations:
* Eight 2.2m diameter fans in each of the four halls in the data centre
used to supply air and another eight used to exhaust air
* A mixing chamber in the facility recirculates air to maintain
conditions in the 5m-high pressurised plenum below the computer equipment
* 8100m2 of technical space at an average capacity of 2260 w/m2 to
a tier 3 standard
* Humidification and cooling coils in the data centre to tune the
outside air condition and remove contaminants
At an average of 9 pence (11.7￠) per kWH, this design will save Wynyard
approximately ￡1m ($1.4m) per hall, which will deliver HP and its clients
energy efficient computing space with a carbon footprint of less than half
of many of its competitors in the market."

"The air is forced up though the floor and runs over the front of server
racks before being exhausted." ここいらへんはビデオを見て下さい
"The system keeps the hall at a constant 24C (75.2F). When it is cold
outside, some of the exhausted heat is recirculated with the outside
air to maintain the right temperature."
"In Billingham, the outside temperature only rises above 24C for about
20 hours a year, , but the facility still needed traditional chillers
for those occasions,"
""It's an ideal climate for this type of solution," Julian said.
"We're moving large volumes of air at a low speed."" (これ大切)
"Installing chillers in addition to building the natural air cooling
added about 6% to the cost of building the data center, Julian said.
The extra cost should be recouped in as few as two years due to the
"Running at a full load, HP has calculated that the Wynyard facility
has a 1.2 PUE, meaning "
"Julian said each of the four data halls actually have a 1.16 PUE on
their own, but that increases slightly to take into account electricity
consumption in other areas, such as the 20,000-square foot office
"Assuming HP pays between 10 and 11 pence per kilowatt hour, using
outside air over chillers should save HP up to $4.16 million in power
annually, Julian said."
"The facility is also harvesting rainwater. In the winter, In the winter,
the outside humidity can drop, and the data center should be kept
between 40% to 60% humidity,"
"Rainwater, which is filtered, is stored in 80,000-liter tanks. If
the outside air is too dry, the filtered water is sprayed in a fine
mist to bring the humidity up before the air passes into the data
"Inside the data hall, HP has opted to put in light-colored server
racks," ... "HP found data halls required 40% less lighting if the
cabinets were not painted black." (これは意外)

"a design choice that can save energy, since the white surfaces
reflect more light. This helps illuminate the serve room, allowing
HP to use less intense lighting. Another energy-saving measure
is the temperature in the contained cold aisle, which is
maintained at 24 degrees C (75.2F)."
