Even the most basic LSS should have means forfiltering, sanitizing and purifying air and waterthat is secure and reliable guaranteeing supply.Food suitable for the occupants (eg infant, non-allergenic etc) should be readily available fromstores for more than the minimal survival periodincluding means of sanitation of the food andassocitaed food preparation, utensils and eatingenvironment.

Life Support Systems have an energy system of some type, even if only the energy stored in compressed gas. Power is used to operate LSS equipment such as climate control, lights, communications, refrigeration, recycling etc. Energy can be stored as fuel, heat, cold or electricity. For sustainability, energy should be harvested from local renewable sources that are adequate (100%), non-polluting, reliable and available whenever required.
Life Support Systems, whether within protectivestructures or less secure as a distributed systemshould provide the basic essentials to sustain life
