Whilst piling the sandbags and during the last months we had to review several times all the pipings for water connection, the gray water drains and all the electricity installation to define where to set the electric sockets, switches and lights. All these details are important to prepare the walls for an easy set up of the electric and hydraulic system.
I designed the house to only have water on the ground level and on the west side of the the house. This simplifies tremendously the piping and reduces material cost as well as improves the pressure in the hydraulic system. We identified the places where the pipes have to run through the wall and there we inserted a schedule 40 PVC pipe to provide a spare opening and simply pass through the regular piping lateran.
For the electrical installation the wood pieces of the eco beams provided perfect support to screw the electrical cases for sockets and switches. The flex tube for the electrical wire can be accommodated in gentle turns along the sandbags. The plaster then will cover the complete wire, tube and cases.
Regarding the electrical installation i still feel completely insecure about the outcome. I purchased the solar panels and the batteries to supply the off-grid hack-shack.
To save energy we will use LED lights. LED lights run on a low voltage DC. So I designed two electrical circuits. The first being 120 VAC to provide “regular” domestic electricity through common sockets powering all appliances. The second circuit will run 24VDC and will power the illumination circuit.
With this design we can separate the illumination circuit and supply the lights directly from the batteries and only the appliances will use converted electricity provided by the power inverter.
Nevertheless there are almost no lamps, switches and proximity sensors for 24V out there in the market and I have the feeling that I will end up producing the lamps by myself. I sneaky feeling is overcoming me that I will require help in this aspect to not produce another fuck-up… Let’s trust that the universe has the solution ready for me and I just haven’t seen it yet!
