[TRNSYS-users] LEED simulation - reference HVAC (appendix G ASHRAE 90.1)

[Jean Marais]

With Trnsys everything is possible. The drawback is the time it takes.
Reporting needs to be setup for a lot of outputs (hours load not met
amoungst others). One of the things I find very "rough" is that there is no
"auto-sizing". You'll need to manually "auto-size" all componants of the
system.
