Hi there, I'm new here. Not sure if this make sense here. But for sure, you will tell if it's not.
I'm Portuguese, I've 47 years old, 3 children, and spent the last 3,5 years of my life on a project I've called Casa Automatica.
The project started by being just an home control system, where I've tried to combined some security features, water control and home network, in a package, using and sharing an internet connection. The system is presented here http://casaautomatica.net.
In the final stage of it's development, I've realized that water (greywaters) would be a great cooling system (evaporation).
I agree with Andrew McAfee. So, for a number of reasons irrelevant for this post, I've decided to developed a housing solution, target for the country side, that:
* could be reinstalled several times
* cheap and when buying it, when using it, and on equipment
* for all (with or without reduced mobility)
The results are presented here. Basically, in terms energy consumption on acclimatization:
I found that air boxes are always relevant but, can even be more important when they are controllable. The house is transportable and that's good (after it's been installed is easy to sell, it can travel if you change your mind about the location, easy to produce). But this also means it has very little contact with the grown. As you all know, this means the summer is a challenge. A challenge that can be overcome by causing evaporation on the roof and by using and controlling a double façade that has no contact with the internal wall.
This means the house design is has to be a box (for now). In my mind that's fine, as long as it achieves the main goals.
The thermal results presented are good but can be greatly improved. They will be better next time, as the computer assumes control over internal air flow.
Let me share a design and a picture to make this post more attractive :)
Please comment, there are very few people (just 1, among my friends) that understand what I've being doing in the last 3,5 years :)
