I use TRNSYS all the time. It is very powerful and flexible, but complicated to use.
I have modeled solar thermal, geoexchange, custom heat recovery, cogen, and other complex plants. It's also great for creating custom control algorithms.
It does have several drawbacks so I would not say it is the best tool for every job.
Modeling buildings in TRNSYS is possible, but it gets very cumbersome after 20 zones or so.
I mostly use it for modeling complex systems in conjunction with eQuest models for whole buildings.
