Data Center Energy Retrofits
The public examination will be held in Auditorium E204 in the Physicum building in Kumpula, Helsinki at 12 o'clock noon on December 12th, 2013. The Facebook event is updated with further details. A Google map is also available.
On p.x the text should read "Figure 2 in Pub. I [...]". Thanks to Markku Kojo for spotting this mistake. It is repeated on p.53, as the same text block is duplicated there.
On p.17 I claim that "HP's Wynyard DC site is located near Dublin, Ireland." while in reality Wynyard is located nearby the town of Billingham in Northeast England.
On p.34 the text should read "CAC alone could yield savings in the order of 0.5 MtCO2e yearly [...]".
On p.36 the installation costs are calculated as "64264 ∗ 469 + 9386 ∗ 2346 = 52180339". The equation is clearly wrong, as I've used more precise intermediate values for the CAC costs in the formula. The end result is right, however. Thanks to Teemu Kerola for spotting this mistake.
