We have successfully submitted about 12 projects to the USGBC and I know of at least two other companies who have also used TRNSYS for LEED EA credit 1 submittals. In my experiences, TRNSYS is an ideal tool for such projects if the proposed HVAC system cannot be modeled using more conventional software. For example, eQuest does not have a radiant floor model but TRNSYS does. TRNSYS is good for doing hybrid GHP (both ground bores and a cooling tower) I would not recommend using TRNSYS for a LEED project that did have a more conventional system (such as VAV) because TRNSYS's flexibility in system modeling means that you have to do a lot of work to model a complete system. Its worth it for complex HVAC systems and a lot of unnecessary work for simpler HVAC systems.<br>Kind regards,<br> David<br> <br><br>On 2/25/2011 01:54, Lars Knabben wrote: <o:p></o:p></p><p class=MsoNormal>Dear TRNSYS users,<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>for different LEED certifications we use at present eQuest for computation of EA Credit 1 („Optimize Energy performance “).
