Item is checked off for better humidity control of the supply air stream.

I noticed for Santa Clara you had only 5895 hours of free cooling. When using the green grid calculator this condition only happens when you check the "Allow Mixing of Supply and Return Air" , why did you select that option. It seems to penalize the outcomeDavid Inoreply@blogger.comtag:blogger.com,1999:blog-3405947399334057664.post-73461815878500116372013-03-21T14:35:52.875-04:002013-03-21T14:35:52.875-04:00Thank Dan.

I have one question: Is the kW you used to normalize the data the IT critical load or the entire facility load?Dan Mascolahttp://www.dchuddle.comnoreply@blogger.comtag:blogger.com,1999:blog-3405947399334057664.post-68062837238158040582013-03-18T16:10:19.655-04:002013-03-18T16:10:19.655-04:00Shane, how do you plan on protecting the equipment...Shane, how do you plan on protecting the equipment inside the data centre from a combination of humidity and gaseous particulates that you are going to create as a result of burning gas on site? Maybe that doesn't matter because the IT equipment is owned by the end customer and the failures will not be able to be specifically associated with the design of the data centre even though the evidence might suggest otherwise.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3405947399334057664.post-35130663739044866452013-03-13T09:15:06.073-04:002013-03-13T09:15:06.073-04:00Thanks for sharing Shane.
