The typical approach is to make the construction of the hole with something which has a high conductivity and low density and high solar transmission and to set an infiltration rate that reflects the likely level of air mixing. And the idea about a flow network to enhance the flow through an opening is a good idea. -Jon Hand ________________________________________ From: <a href="mailto:esp-r-bounces@lists.strath.ac.uk">esp-r-bounces@lists.strath.ac.uk</a> [<a href="mailto:esp-r-bounces@lists.strath.ac.uk">esp-r-bounces@lists.strath.ac.uk</a>] On Behalf Of Hall Monika [<a href="mailto:monika.hall@fhnw.ch">monika.hall@fhnw.ch</a>] Sent: 10 March 2010 12:40 To: Walsh, Cormac; <a href="mailto:esp-r@lists.strath.ac.uk">esp-r@lists.strath.ac.uk</a> Subject: [esp-r] Re: Open Holes in Surface Hi Cormac, you could calculate an open hole with an flow net work.
