It does provide thermal mass, but that’s less effective outside your insulation).

Professor David Sailor of Portland State University developed the Green Roof object for Energy Plus that uses a a finite difference algorithm and works well. The problem with </span>eQuest<span style='font-family:"Verdana","sans-serif";color:#336666'>/DOE2 is that it is based on a conduction transfer algorithm, and can not really emulate the effects of a Green Roof. If you need the easy to use inputs, I suggest Design Builder to generate the Energy Plus file. </span><o:p></o:p></p></div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p></div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Verdana","sans-serif";color:#336666'>Best of luck, and feel free to ask if you need more about EP/DB..</span><o:p></o:p></p></div></div></div><div><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>On Thu, Mar 1, 2012 at 6:04 AM, John Aulbach <<a href="mailto:jra_sac@yahoo.com" target="_blank">jra_sac@yahoo.com</a>> wrote:<o:p></o:p></p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>OK, my fellow Raiders of the Lost BTU..<br><br>What would be your advice for developing a green roof in eQuest?
