    How will we build Our Future Home? What are the designs and materials of the "top, sides, and bottom" for our future structures?

    I see walls and roofs getting lighter and moving to a post and beam system. Less structure means more insulation. Also more adaptability and potentially more durable. Commercial buildings already use these techniques we can learn a lot from in residential.

    All homes in the desert should be a least partially underground. It is the coolest place to be!

    I like the post and beam idea. it is one of the oldest structural formats for built structures. I would hope that we could move away from either wood or metal as primary structural members, however. 

    There are structural components availble made from recycled plastic that have been used to buil bridges and railroads. 

    Such  composite materials were used to build a bridge at Ft. Bragg NC that supported loads (Abrams tank) of 70 tons.

    I have an e-mail in Axion requesting info on products that might apply to post and beam residential construction.

    Buildings with Underground components ordinarily require waterproofing systems.  Such systems are readily available but they are not always 'green friendly'.

    I'll see what I can find.

    Including gray water systems automatically in every new-build to water landscaping would be a good water saver in the future.  Although Arizona has water now, supply may not be as great in the future.

    This would be super cool, a few ways!!! It would be much more energy efficient since you are using the earth as natural insulation but it would also be super neat to live underground!! =)

    With regard to Axion recycled Structural Composite Plastics, I had e-mail back from marketing guy who says that, while their products are readily usable in exterior residential applicattions - shade structures, bridges, deckings-, they do not currently have structural products available that would meet the shear/expansion/contraction co-efficients involved in residential structral wall installations. there could also be connection/attachment issues with other structural components or substrates.

    there is another residential structural application similar to post and beam that uses 16" wide I-joists that has  been used in passivehaus construction.  i will see what i can find out about that structural application.

    Going underground has its benefits, but there are costs associated with that which may not make it the most sustainable option. And look at the typical home in most of the country, the basement is the utility space. This is because it is difficult to get windows/daylight into them. Most houses with basements have them unfinished and they become a storage area for things that will eventually become part of a yard sale. And basement walls have a lot of earth to resist against, so are going to be concrete which has its own eco-issues. Generally speaking, there may be better ways to reap the benefits of the coolness of the earth without digging a basement into it.
