Continue to use energy-intensive and polluting in manufacture materials is not environmentally viable. Maintaining or continuing dependence on long-distance material transport who will shape the building nor is it. Despite improvements in industrial production processes, perhaps eventually there is nothing more cost-effective, economically and environmentally, than buildings that include technology and local or regional materials with low impact, built by local labor. Advantages of the prefabricated some factors that advocates of this type of construction (of prefabricated houses) point as benefits are as follows: the building would become a continuous activity, at least in the production plant, which throughout the year waned components of future buildings. This would allow that workers in the construction sector, or a part of them, had a steady employment least subject to the variations of the rhythms of the sector.
Linked to this, we find that other promoters of the construction defend as an advantage: the fact that labor that would work in these assembly lines would not require specialized training. This is interesting to developers of housing in countries in which, for example, is usually built a large number of wooden houses, as in United States. This new construction system would dispense with a professional Carpenter and employ a worker not specialized in the Assembly line. Of course, this worker would receive a lower wage. Fast mounting, for both modular homes and buildings with part of its prefabricated components, it shortens the time of execution of the work, in some cases by half, although it is most spectacular in the case of houses fully built in factory.
After transport to the construction site, a prefabricated House can be mounted, closed and occupied in a matter of days. Saving of materials used in work, with elements prefabricated buildings or modular houses, possible construction or mounting in dry, i.e., you can dispense with the mortar. Reduction of construction waste, arriving the prefabricated components at work, reduce the amount of waste generated in the ground where the construction (packaging, breakage of parts) is performed stated that final products that enable energy savings can be created.
