The major concept of the House is to be transportable and easy to build all over the world.
The prototype of The B&W House was therefore conceived as a modular plan made up of nine squares, For transport and assembly purposes, the house has been divided Into three mobile units.
The foundation of the prototype is quick and protocolary. It is an active system suitable for every type of ground.
It consists in steel plates with guides. On top of them, the hydraulic jacks of the trucks work as support of the House and enable the leveling between the three units and to be the appropriate according with the ground slope.
The structure of the House is built in tubular steel, and thus the hydraulic system and installations of the house can be placed inside them.
Each unit of the three in which is divided the prototype, has got standard dimensions to be transported in highway without special permissions.
In fact, for design purposes we had first to doUblecheck the permitted dimensions of the truck to comply with both the European and the American regulations.
The conclusions said that we had to work within these dimensions in feet: 44.8 long x 8.4 wide x 13.3 high.
For the contest week in Washington D.C., the B&W House has been shipped in a roll-in roll-on boat from Antwerpen (Belgium) to the port of Baltimore (United States).
The modular units of The B&W House are assembled in such a way that the process can be executed in one day (excluding the installations) and is done by following these steps:
- First, we prepare the guides and place the steel foundation plates onto the ground (these can be adapted to every ground surface).
- The middle truck enters the plot and parks into position. We proceed then by positioning the other two trucks 6 inches
-15 cm- adjacent to the central truck.
- Hydraulic jacks under the platforms extend out until they reach the ground and lift the trucks slightly off the ground. - The next step is to take out the wheels and the tractor units.
- TeamSPAINīs Decathletes push then the side trucks towards the central one without needing forklifts or cranes. After that, the three units are bolted to each other.
- After that, we bring the units down using the hydraulic jacks and lower them so that they are resting 1.5 feet -45cm- above the ground.
- Next, we prepare the roof by lifting the solar roof structure with four electric protection screws located at the corners of the house, but hidden inside the structure.
- After that, the structural pyramid containing the skylight is locked into place at the top of the house.
- The roof will be brought down and released onto the vertex of the pyramid: the ball-and-socket joint.
- From there, we unfold the wings to complete the solar roof so that it measures 29.5x29.5 square feet -9x9 square meters-.
The movement of the roof is controlled electrically by the home automation system through the four cables located at the corners of the roof. The chosen assembly and transport systems of the House offer security, speed of construction and economic advantages. These aspects are some of the most appealing elements of The B&W House prototype.
Apart from the basic assembly process, the various Installations have to be connected and checked.
Once the three units are bolted and before the house is brought down to its final level above ground, we proceed to execute these following steps:
- First, we connect the plumbing and HVAC pipes under the platform, and adjust the electrical connection of the solar tracking system of the roof.
- After that, we place all deposits under the platform and adjust their pipes in the technical room of the house
- Then we link the flexible air conditioning ducts together under the grids along the greenhouse, and the water hoses for the evacuated tubes.
- We also adjust the pressure pump to the plumbing system.
And in parallel with the previous actions:
We connect the water hoses of the thermal panels and set up the electrical connection of each photovoltaic roof (roof and facade panels).
And we connect the electrical systems between the three units (both power and home automation).
Once everything Is connected, we start the pressure tunning and we finaIly check the systems performance .
