After that, I think that if you want to get daylight factors plotted as numbers, the menus are self-explaining. I don't know how to plot daylight factors as countour lines from ESP-r. But I did not look for a way to do it yet.

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?
