Hello,
We have a speed skating oval project. Should the energy used for ice rink modeled as process load? We think this will be the major energy consumption. Can we consider the energy saving of this load? If it can be, how to model the baseline chiller?
Thanks!

Yes it is a process load.
You can claim savings through an exceptional calculation. Under this method you must justify the baseline as standard industry practice for an new facility in your area.
If the chiller used is the same type as can be used for space conditioning you can use the efficiency in Table 6.8.1 for the baseline.

Thank you Marcus!
The window wall ratio also need to adjust to 40% maximum?
And the energy used for ice rink will be affected by building envelope which are not same for baseline and proposed case. So this process load won't be the same for two models.

Yes.
The process load must be the same but that does not mean that the energy use must be the same. In most cases it is the same but in some situations other interactive strategies produce savings and that is OK. So you model it identically and make sure to thoroughly explain any savings to the reviewer.
