We have disignated smoking rooms in the building. Now we are planning to carry out negative pressure defferetial test for thes rooms. There are 2 questions.
1. Even if the spaces are devided by slab to slab wall, do we need to measure the difference between spaces?
2. As they are located in same place per floor, smoking rooms have other smoking rooms as their vertical adjaceny rooms. In this case we believe there is no need to have negative pressure or defference between these rooms. Are we on the right track?
Thank you.

Shoko, you do need to "verify" the pressure differential, even with slab to slab partitions.I think you could probably get away with skipping the measurement between smoking rooms, but it's probably necessary to note that approach in your narrative, as it's not the standard approach.

Tristan, thank you for your reply.
We have problem to measure differential pressure between two spaces, when they are not connected by door way. It requires long tube to connect two places if we use differential-pressure measuring instrument. Do you think we can measure "gauge pressure" or "absolute pressure" separately and compare them?
I believe we have to close the door when we implement measurement. With instrument’s tube, the door cannot be shut properly.

Shoko, that sounds like the approach you need to take here. I would think you'd need very accurate instruments.
