Can you take credit for occupancy sensors that control HVAC systems? I am thinking probably not for system operation E.g setbacks, agree? But I am unsure for the ventilation. It seems a bit waffly trying to determine when the spaces are "occupied" as technically they are 24/7 but occupant will come and go during that time. Should the baseline be 24/7 for ventilation and the proposed as per expected design for ventilation taking account occupancy sensors...? Thanks
