When modelling the Baseline where the building is existing (not a new build) what is the procedure for selecting the baseline constructions in the model. This building is outside the US. Do we need to refer to ASHRAE 90.1 baseline constructions and if so how do we know which ones to choose.

The Baseline constructions are defined in Table G3.1#5Baseline. For an existing building see G3.1#5Baseline(f).

Many thanks Marcus. I think you are referring to ASHRAE 90.1 2010. We are working to the 2007 ASHRAE. Does this change things ?

I was referring to 2007. Both versions are identical on this issue.

For an existing building do I still need to model all 4 baselines to pursue this credit.

Existing buildings do not need to be rotated so one model for the baseline is all that is required.
