The material is purely educational…there is no sales pitch attached, which is refreshing. You can purchase a number of booklets on various topics. The booklet most relevant to your needs right now would probably be the “Introduction to HVAC Systems” booklet, which is part of the Air Conditioning Clinic set. Here is a link to all of the booklets:<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><a href="http://www.trane.com/COMMERCIAL/DNA/View.aspx?i=446">http://www.trane.com/COMMERCIAL/DNA/View.aspx?i=446</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I hope this helps,<o:p></o:p></p><p class=MsoNormal>Christian<span style='color:#1F497D'><o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> bldg-sim-bounces@lists.onebuilding.org [mailto:bldg-sim-bounces@lists.onebuilding.org] <b>On Behalf Of </b>Anup Rathi<br><b>Sent:</b> Friday, July 19, 2013 12:50 AM<br><b>To:</b> equest-users@lists.onebuilding.org; bldg-sim@lists.onebuilding.org<br><b>Subject:</b> [Bldg-sim] Help with understanding different Baseline Systems and efficiency of one over the other<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-IN>Hello All,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-IN><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-IN>I am an Architect by training with my masters in Sustainable Buildings.
