The constructing envelope was constructed multi-layered, each layer shielding towards electricity loss and terrible infiltration of air or water. The team used a soy-based open mobile SPF inside the outdoors walls, but closed cellular SPF in the roof and floor. For the outer walls, the SPF turned into protected with wall sheathing, a liquid applied membrane, and then inch thick polystyrene rigid insulation for added protection against "thermal bridging". Over top of the polystyrene are "thermo-treated wooden" siding panels which purposely shed rainwater into collection equipment' via vent strips. Due to the unique venting strips in the wood siding, a further layer of 'furring' changed into had to create a ventilated cavity.
