I see. So you determine the global PMV from an average (absolute or you sum positive and negative?) of the hourly PMV of design weeks (either summer or winter), right? So you get two average PMV: one for winter and the other for summer and then, the "worst" value between the two is the one put in BREEAM tool.
What I do: I assess zone by zone the PMV hourly during occupied hours. If 5% of the occupied hours are outside Category B (method A described in the Annex H of the norm ISO 7730:2005) then that zone is not compliant, and compliant if it is below 5%. Then I calculate an average PMV of the absolute value of the hourly PMV of the occupied hours. At the end if 95% of the spaces are compliant then the building is compliant and I determine the average PMV and PPD corresponding.
