humid environment

My husband and I are planning to move to our ranch in East Texas. Our dream is to build a green self-sustainable home and utilize solar for electricity, rain water catchment for watering our garden, as well as using our own well for drinking water. However, one issue we are contending with is the high humidity factor in East Texas. We have discussed several options, 1. building a timber framed home with SIP panels, which utilizes far less wood than a traditional wood home, 2. a straw bale home, which is very well insulated, 3. as well as building separate attached buildings that enable you to cool/heat only as needed.

We've seen several TV shows on building green homes, but haven't seen one built particularly in a hot, humid type of environment. Please let us know if you have any suggestions.

Thank you!
