Subsystems:
1. Elevators
2. Transformer Stations
3. Communication Networks
4. Air ducts
5. Sewage-treatment plants
6. The multi-level base structure
7. The facilities for manufacturing
And it requires analysis of how these can contribute to the fundamental functions (systems) of the city:
Fundamental Needs:
1. Air
2. Food
3. Water
4. Shelter
5. Movement
6. Communication
7. Work (effort, cost, convenience)
8. Leisure
By plotting a table regarding the relevance of subsystems
of a Compact City to general city functions, on a scale of 1-5, we have come
up with the subsystems and their importance / effect on different aspects.

The above table ranks subsystems with numbers from zero to five
and helps in a qualitative way to indicate the relevance of various subsystems
to the general functions. For example, as far as the goal of interior climate
control is concerned, elevators ranked 0 (low) but air conditioning ranks 5
(high). However, for transportation the elevator is ranked very important (5),
but cost is not the overriding factor in making decisions about vertical transport
since the elevator is one of the lifelines of the city, so in terms of its relevance
to the low cost of the city, it was assigned a low rank. The three-dimensional
structural design and shape for a Compact City can greatly affect transportation,
cost, climate, and labour savings by eliminating delays. Organizing time so
as to avoid congestion due to peak loads can contribute to the available of
transportation, save labour costs, and reduce dramatically the cost of facilities.
The secondary power sources are highly relevant to reducing delays because vertical
transport can be called upon for emergency evacuation. Evaluations similar to
those stated, but on a more detailed quantitative basis can be used as part
of a total-system model to develop the best of various alternative plans and
a detailed schedule of the quantity and timing of activities necessary to build
the city.
