HRV Server rooms

[AbsoluteWDJ]

Has anyone out there an example of how they would size heat recovery ventilation within a server room. I like the idea of these systems and will promote them because they supply free cooling in winter and can raise the r/h within the space. The sales reps that i've spoken to in the past work on 10 l/s per person, so I have a couple of questions in relation to this.
1. How would you size HRV with no people occupying the space?
2. Do you allow a certain % of extra cooling duty to allow for a high ambient (say 30c) with HRV in operation?

1 Air changes per hr
2 Add no more than 10% if in full HE mode

The problem with these numbers is that the ahu can end up being very large. just quote a VAM1000 every time ;-)
