[esp-r] Re: dailight factors+cfd

[Jon Hand]

Ventilation studies in ESP-r almost always start with a flow network.  It is computationally
efficient (so you can do assessments looking at literally every minute of the year) you can
control flow paths (e.g. adjust windows & turn on extract fans).  There are also several
example models, a chapter in the Cookbook that discusses it and a couple of video tutorials
that show the process of planning and creating a flow network.

You can learn a lot via flow networks.  Later if you want additional resolution then
you might explore CFD.

Subject: [esp-r]  dailight factors+cfd

Dear All, I can now use radiance desktop via ESP-r and create and view images. I need to find daylight factors, does anyone know how? I would also need to do some ventilation study and I was thinking of using the cfd facility within esp-r.  I would need to do some tests with and without trees, is there a parameter such as porosity within esp-r which I can use to better define the trees that at the moment are just blocks of solid obstruction? Let me know,

kind regards
Arianna
