Are Insulated Concrete Forms and Gigacrete panels good?

I want to build a house to passive house standards and keep it to a relatively small budget by potentially doing some of the build myself. I stumbled upon the history of ICFs and Gigacrete while researching building materials, but haven't seen a lot of passive houses built with these type of insulating materials. Is there a reason why? Insulating concrete forms would seem to be a pretty efficient method of building houses, and can be air tight without a lot of additional work, dont have thermal bridges, and they tend to have a hard time catching fire (important where I live). I'm looking for an educated opinion because I am such a construction rookie - but ICF as a construction system has got me interested.

I'm also planning to build a house, not necessarily up to passive house standards, but as green as economically possible. For the exterior wall I'm giving strong consideration to using Nexcem ICF wall forms. You may find technical details online about this pioneer of ICF blocks and ICF construction and videos of a builder describing how he used Nexcem ICF wall forms in construction. Note, Nexcem was recently known as Durisol, so you may find additional information online under that brand - or if you're interested in the definitive history of ICFs blocks & ICF Construction including Durisol, that's here..
