Shut-off modules for conserwing power and oxygenLet's just say we started-up the base...we don't need at the beginning of the game some of the modules like: mining, farming, garage etc.. At the start - we are low on air and it's possible we will be low on power too. Her's an easy solution used in submarines: shut-down the sections of the base you don't need at the time.
Let's just say that each section needs 1kW of energy (for heat, ventilation, light etc.). By seeling-off 3 modules during dust-storm, we get 3.000 Wat''s of power, that can be used to support the basic modules, like Life Support Module.
But that's not all...each section is (for instance) 50 cubic meters of air. By sealing (depreasurizing) 3 out of 6 modules, we save oxygen and the air get's recycled quicker (the proces of creating air for the base is 50% quicker).
Sealing-off modules is easy...just close the hatch that the module have, depreasurize, and cut-off power. Inside, there will be very cold and with no air.
This idea doesn't even require that each module had a preasure/electric panel, becouse all modules get their air/power from the LSS module by vents or cables. Inside LSS there could be an air/power distribution panel, by which player can decide, which modules doesn't get's heated, and get's no fresh air. That section needs to be closed by airlocks off course.
