TRNSYS can be used for LEED certifications. 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>

On the one hand the programm eQuest is not quiet user

makes sense to use TRNSYS also for the LEED certifications.<o:p></o:p></span></p>
