Hello my first post, 

I'm wondering if there is anyone about who could advise on the calculations involved in determining flow networks for natural ventilation. I'm studying a distance learning masters in sustainable design and there is something for this assignment I'm just not getting. 

I've been through 

A Guide to Energy Efficient Ventilation, Martin W Liddament – AVIC

Air Infiltration Calculation Techniques - An Applications Guide, Martin W. Liddament – AVIC

2009 ASHRAE® Handbook Fundamentals

Ventilation for Acceptable Indoor Air Quality, ASHRAEE standard 62.1

And several other presentations, book and publications.

and in part of this I found a couple of Discussions here that have helped but not fully covered what I need. 


If anyone can help I'll go into more detail but the basic layout is below. Obviously I don't want to solution calculated for me as that would be cheating but just people to bounce off would be nice.

Pascals for stack has been discussed to death here

Wind is pretty easy to find & if need be I would recommend googleing Bernoulli's principle on wind

Unfortunately just looking at the diagram without some context it is hard to know what you need help with

https://www.linkedin.com/groups/6942179/6942179-6030115404729307139           'm not sure this is what your exactly looking for Daniel but it should direct you to the right area.

I asked this question to Colin Genge really one of best minds regarding this in the business. Anyone can theorize but measuring is why most of us are here. If your going to measure one thing against another do it the same way every time. This escapes some in our industry...Anyway take the time to read what he wrote on set-up and join his group. Best of luck and share what you come up with.
