The new cabin brings substantial advances in sustainable technology. Heat for all cabins is now generated by an external wood-gasification boiler and transmitted via underground hot water pipes. The cabin itself uses both a radiating retention tank and in-floor radiative heating. A new photovoltaic system was installed that generates more than 10 times the original electrical capacity and maintains a net output onto the grid. Furthermore, enhanced fire alarms and water suppression systems were installed in all residential cabins to prevent catastrophic fires.
