Hi Friends, Please download the excel from the link www.dropbox.com/scl/fi/9rggqlumyzb6qpan0812g/Stair-Pressurization-calculation.xlsx?rlkey=c85ip74i9rh2sy8j9mv056rx6&st=o15etws5&dl=0
When I submit the report in qatar civil defense, I have considered only the door, windows leakage with number of doors open. Since the stair walls are fire rated, water leakage proof I have not considered even walls also. But in UAE Calculation, I additionally add walls only.
i have one question 52.8 m is the total height of stair case and we mentioned height in inches 173.2 as per 4.4 m is that we are calculating only 1 floor in height only not full height of stair case
Hii.. In sl.no.14, i multiplied with number of floors 12 nos. So full height considered. Hope u got the answer for why I considered 4.4m related inches 173.2 for your old question.
@cygnusenglishspeaking9505 most of the counties have local codes like qatar has qatar civil defense, UAE has UAE fire and life safety side. Similarly india has NBC. but main reference for all these files are NFPA. Local codes have additional requirements based on country requirements
Hi it was a great session, the fan selection was 17305 cfm will it feed to every floors of same cfm to maintain the desired pascal. If not than what will be the desired cfm requirement for each floor for the desired pressure.
Suppose staircase have three door at a floor in that case will we consider the 3 door open at fire origin,exit ,either floor of fire origin that means 9 door at a time.
Inside staircase each floor level only one exit door will come. I don't know which project u found 3 doors in one floor. Your question probably wrong 3 doors in one floor how it will come in staircase
Hi Friends,

good and well explained and thanks for your support to all of us
sir why have you not considered the leakage through floor and ceiling ? any specific reason? please suggest
Hii thank u for your comment

Nice explanation, Easy to understand... Really great videos easy to understand
Thank u for your comment ❤
Please give your mail id if u need excel also
brother well explained in a detailed way. Thank you for posting videos with practical design methods. please send the excel to me
I sent to u dear

In india which guidelines should we consider NFPA OR NBC ??
@cygnusenglishspeaking9505 most of the counties have local codes like qatar has qatar civil defense, UAE has UAE fire and life safety side. Similarly india has NBC. but main reference for all these files are NFPA. Local codes have additional requirements based on country requirements
Nice explanation. thanks lot
Thank u dear for your comment
can you explain how the 17.9 value came ??
17.9 is the constant value in the formula
Hi it was a great session, the fan selection was 17305 cfm will it feed to every floors of same cfm to maintain the desired pascal. If not than what will be the desired cfm requirement for each floor for the desired pressure.
We will provide the equal flow to each level.
i.e 17305/no.of floors with vcd at each landing in case of multi injection is it like this? @@mepworld3385
Good explanation brother
Thank u brother
Suppose staircase have three door at a floor in that case will we consider the 3 door open at fire origin,exit ,either floor of fire origin that means 9 door at a time.
Need some clear explanation of your question. U mean 3 exit doors in one staircase/floor.
3 doors are there in the lobby or staircase?
Inside staircase each floor level only one exit door will come. I don't know which project u found 3 doors in one floor. Your question probably wrong 3 doors in one floor how it will come in staircase
I hope u are talking about lobby area.
Lobby has other Pressurization that is not related to staircase Pressurization
Hello sir
Please send this excel sheet of staircase and lift well pressurisation
@liazhar0 sure I wil provide. Please write your mail id here or u can send a mail to nagarajan62392@gmail.com

Thanks for your support sir and if you have smoke extraction video please upload with sheet
@@liazhar0 sure I will post in the future
❤❤
Thank u
Kindly share the link of excel sheer
@@engr.muhammadshahid yes sure. Can u share the mail id here
Sir I didn't not received it yet. Sir I need it urgently.
@@engr.muhammadshahid I told u to post your mail id here
@@mepworld3385 I send it here but it disappears even its posted. What could be the problem.
