Very good Explanation, thank you very much sir. GOD bless you.

[jasirhayder]

thank you so much, this is very helpful specially for all those who are new in field

[AsadIslam-benj]

Very well described the staircase pressurization system with details, it's really helpful.

[aymanbinafeef]

Thank you I'm watching you from Saudi Arabia +1

[rajeshmohan]

You presented very rare calculation sheet. Practically not even in one percent of buildings this kind of calculation is done.

[jersonirinco]

thanks for the free resources❤ and for that, a new sub & a like. keep it up bro!

[joegalford]

Thank you for this video. I appreciate the information.

[SyedAqueel]

Great video, I would like to ask whether volume damper is required for air balancing on each floor landing or no need for Air Balancing???

Hi. It was a concise explanation for the stairwell pressurization calculation's. Can you share to me the excel table shown? Thanks in advance and would appreciate it much.

[ganeshkamble]

Nice explanation. Thanks alot.
Can you please explain on below.

1. Here in this example there is only 1 no. door on each floor but you have considered A1 and A2 which means 2 nos. of doors. This is just for example only or we have to consider A1 and A2 always for 1 door per floor. If not then can we put A2 as Zero.

2. You have considered A1 and A2 in parallel. This is also for example or we have to consider it this way in case of single door.

As per my understanding, doors in series means one door besides other door and parallel means 2 doors in front of each other. Can you please explain as I am new to this.

Great job. That was useful
Thank you.

Thanks you for your video and explanation. Which flow that we use to select fan? Relief Air requirement or Stair Pressurization Air flow?

[aymanabdelhalim]

Thank you for the informative video, I have a question for a case there is a pressurized smoke stop lobby before the staircase. How would the pressure difference be calculated assuming that the pressure difference bet. the smoke stop lobby and the corridor is 25 Pa

[anuraganil]

Can you please explain more about pressure relief damper and how it will operate at fire conditions?

[patrickochan]

Thanks, can you please share the excel sheet?

[gounka]

Thank you. Good video. Do you have the calculator in the feet measuring system? We have a project where the engineer put a static pressure sensor in 1/3 of the stairwell height for a 9-floor building. Should it be a differential pressure transmitter? How should we choose the correct model number?

[ganeshkamble]

How do we get the door closing force. Do we have to ask this to the door supplier or just consider 25N as standard.

[thepurposeofmyexistence]

Dear sir nice video, but when does we require to install stair case pressurization system and smoke extraction system, I mean is there minimum area requirements or minimum ht of building or no of floor given in nfpa

[ganeshkamble]

How do you calculate the pressure difference between the Indoor space and staircase space. Or is there any standard for that.

[mohamedshibin]

Is it required to add additional pascal while doing ESP for pressurization fan?
