Specifically, I am trying to model the Vista EnerLogic low-e film (since it is eligible for tax incentives). I’ve used Optics5/Window5 to construct the glass type using the EnerLogic applied film (NFRC ID# 2545) and imported that into eQuest. When I test this retrofit in a sample building, the savings are not what I expect (~65 yr. payback, assuming $7 installed cost). I would expect to see a payback somewhere around 10-15 years. What bothers me is that in the model, the heating load increases, which would be expected for a typical window film, but this film claims to have savings in all seasons due to the ability to trap heat in the building. If anybody has had any success in modeling these window films and could provide me with step-by-step instructions or any guidance, it’d be greatly appreciated.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks!<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Book Antiqua","serif"'>Dan Raphael</span></b><span style='font-size:10.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Berlin Sans FB","sans-serif"'>Building Performance Analyst</span><span style='font-size:10.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p><p class=MsoNormal style='margin-top:3.0pt'><b><span style='font-size:10.0pt;font-family:"Book Antiqua","serif"'>Integrated <span style='color:red'>Design Solutions<o:p></o:p></span></span></b></p><p class=MsoNormal style='margin-bottom:3.0pt'><span style='font-size:9.0pt;font-family:"Berlin Sans FB","sans-serif"'>Architecture, Engineering, Interiors & Technology<b><span style='color:red'><o:p></o:p></span></b></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Berlin Sans FB","sans-serif"'>1441 W.
