For a Collocation instead of an Enterprise Data Center, where the developer has no control over the servers to be installed, how would the servers be modeled?

The issue of control does not matter. You will need to work with those who do have control to determine what is likely to be installed.

Marcus, thank you for your reply. The problem is that the Data Center developer is not aware of the server types because those will be determined by future clients who will make use of the facility. Should we make assumptions about the servers efficiency (i.e. from previous experience from an existing data center) which may be used by the clients?

You will need to include the energy use of the IT equipment in the models. So if you do not know what will be installed you will need to make assumptions.

Marcus, further to your reply above, do you think from your experience that out project team should submit a project CIR in an effort to clarify the issues about the unknown servers? Apparently, as process load makes up almost 75% of the total energy use in the DC, energy efficiency of servers is of major significance when claiming significant energy savings. And if making assumptions, what those should be based on? In other words, assumption may need a reference to either a "baseline scenario" for the proposed case (based on average local trends) or client commitments. The latter (client commitments) would be a solution since the clients pay for the energy they use so they have a strong interest in using high efficiency servers.

I think that you only need a CIR if you trying to claim any IT savings. If you are modeling the IT equipment identically in both models then you probably do not need one.
To claim savings it sounds like you will need a baseline and client commitments (lease requirements if it is a CS project).
There is a spreadsheet that you can use to calculate savings that establishes the baseline as well - http://www.usgbc.org/resources/minimum-energy-performance-data-center-ca...

Thank you Marcus. We reckon that in an effort to reduce energy demand due to process load we definitely need to make assumptions over our servers efficiencies. As a result, IT load will not be modeled identically in baseline and proposed buildings, otherwise there will only be minor reduction in energy use, which is not desired. The owner company runs another collocation DC and is regularly awarded for energy efficiency achieved, so it is of priority to achieve a considerable energy use reduction for this project, as well.
Apparently, this is a NC project (not CS).
