   Congratulations! It's well deserved recognition. We read it regularly here at AFCO Systems and find it be substantive and informative. Best wishes for your continued success.

   Thank you Tony, I feel quite excited about being involved in a small part of the IT industry that is beginning to get it about energy efficiency. I call it the perfect storm between economic self interest and social responsibility. Feeling good about making or saving money is a real winning formula.

   If you have ideas about articles you would like to see or even your own post of point of view. Mail me through the form on the contacts screen (stops the robots spamming me).

   Best

   Steve,

   You ask questions on here and make the observations that some people wouldn't even dare to admit that they have in their heads. The Hot Aisle is informative, thought provoking and inspiring. This is a well deserved accolade, and only the first of many I'm certain of that!

   Congratulations! I look forward to reading about an even higher rank in the not to distant future.

   Best wishes
   Andy

   For energy efficiency as awarded by BREEAM or LEED where do these fit in with data centres PUE. What should a buyer use in selecting a data centre other than the usual requirements ?
   Is it possible to buy electricity for more than 3 years in advance ?

   David,

   BREEAM and LEED are building standards aimed at ordinary buildings rather than Data Centers that have specific technical requirements. So for example we might find that BREEAM specifies a particular density of insulation for building rooms whilst a data center might benefit from very poor thermal insulation. LEED is similar in that it is not specific for Data Centers and might give inappropriate advice and guidance for maximizing energy efficient by being able to dump heat rather than conserve it.

   PUE is specific to Data Centers and gives a reasonable approximation of the relative efficiency of the building assuming 100% utilization of the compute resource. A PUE of 2 means that each KW of plug load is matched by a wasted KW of cooling and power protection load. Often PUE is a range of values as for some data center designs, cooling load varies by time of day and season.

   Try http://www.thehotaisle.com/2008/05/15/how-effic... for a pretty good explanation (if I say so myself).

   Hope that helps.

   Now the most important need is energy sufficiency.. It is necessary in every product and development.. so we have to find out some good things in it.. I've just found a demo video regarding this.. Let me post in the next comment..
