Our project recently been awarded, and we are now ask by owner, how to get prepare for re certification process. one interesting topic that we bring onto the table is IEQc2.1 (occupant survey). based on our experienced in conducting occupant surveys process, we took almost 5 months to complete the whole process from end to end. Our building have 81 difference tenants, and average daily occupant coming to work into our office tower is 11,000 people. as if we to conduct the survey according to ASHRAE 55 -2004 recommendation (once every 6 months). If were to follow the recommendation, we anticipated to use up great amount of human resources yet create some discomfort level to the tenants. Has anyone encounter this issue before during re certification preparation with building owner?
I'd contact GBCI and get a clear answer as previously this need only be repeated every TWO years (unless of course you had major faults highlighted in the survey that required operational or physical changes to the building). In any case with that amount of people I'd take the 'average' number option rather than trying to do the whole 11,000.
