Re: [TRNSYS-users] TRNSYS for LEED

Lars,
 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.
Kind regards,
 David

Dear TRNSYS users,

 

for different LEED certifications we use at present eQuest for computation of EA Credit 1 („Optimize Energy performance “). On the one hand the programm eQuest is not quiet user friendly, on the other hand we use TRNSYS for DGNB (German sustainable building council) certifications, from there it makes sense to use TRNSYS also for the LEED certifications.

Well, is it allowed to use TNRSYS for LEED certifications and does any guidance exist for this approach?
