There is a book called Serious Straw Bale which discusses strawbale homes in all climates. My biggest concern, because we live in a very moist climate, is moisture. In the winter the warm, moist air inside the house moves through the walls (plasters that can "breathe", like natural and earthen plasters as opposed to cement are essential) to the cool, dryer air outside (as warm air holds more moisture). As it cools as it passes through the walls, at some point it will hit the dew point and turn from water vapor to water. My concern is will this cause a major problem in the walls. I also think strawbale in moist climates is fairly new so we don't know much about the longevity, as opposed to 100 year old Nebraska homes that are still doing great. Right now there are some great Pacific North West "tester" strawbale buildings in which they monitor the moisture over years, so hopefully some really concrete information will be coming. That aside, I think having a good, high foundation, generous overhangs, and a good breathable plaster is the most important thing. Some other concerns are that it often can end up costing more than you think it will, some states are wonderful permit wise, some states can be difficult. Many people build a post and beam, strawbale infil home because it is easier to get permitted and you can build your roof first, so your bales won't get wet. If I lived in a dryer climate I would do strawbale in a heartbeat. Given where we are, we are debating the pros and cons of strawbale, cordwood and cob and trying to find what will work for us.
