Hi all, Thank you guys for bringing this up. I'd like to ask a simple question about the occupancy assumption. Do we need to match the occupancy density to the assumed occupancy (usually peak or dense) by the HVAC designer, in the model? Often times HVAC designers assume more occupants for peak load. I understand that simulation needs to be close to reality as possible but if I will reduce the occupancy close to reality, savings may be reduced due to increase in the HVAC equipment capacity difference between the baseline & proposed because the baselines equipment will be auto-sized (1.15 ratio for cooling, 1.25 for heating). Have you experienced a comment from a reviewer picking on inconsistencies on assumed occupancy between other credit/prerequisites? Thanks, Bob 2011/9/29 Nick Caton
