[Bldg-sim] Fresh air calculation for naturally ventilated building

[Chris Yates]

Sadaf,

I did this on a LEED platinum project a while back. I recall that we had 
to invoke a couple of clauses in ASHRAE 62.1 to allow us to use thermal 
modelling with CO2 as the metric (at the time 62.1 only had a very basic 
natural ventilation rule of thumb such as minimum distance between 
occupants and openings). IES was used for the analysis, but you could 
use any thermal modelling program that incorporates network air flow 
(e.g. E+, TAS, IDA).

Without being able to get access to the latest 62.1 I can't help further 
- sorry.

You might have trouble meeting ASHRAE 55, depending on your climate.

Hope this helps.

Chris
