After solving the pipe, started the foundation and structure of the house.
At first we considered several alternatives esctructuras more sustainable than concrete. Among these alternatives include the biohormigón (s lightweight concrete with rice husks or sawdust and whose binder is lime), wood structure and freestanding walls. But the area in which housing is of high seismic risk is why we have opted for a traditional concrete structure, as is the construction system that offers more guarantees.
However, we have tried to do the foundation and structure as sustainable as possible, within the major limitation of having opted for the concrete. We have reduced the amount of concrete used, since some of the sides of the basement contact to the outside, walls can be multilayered as the rest of the house. As we discussed in the blog entry estrasystoles, the drain pipes are made of polypropylene, more environmentally friendly material than PVC. In addition, the vaults are ceramic structure, instead of concrete commonly used. The ceramic slabs are more expensive, but I think it's worth the expense because they have a better energy comortamiento, according to bioclimatización system of housing, and require less CO2 emissions during production.
