Do you agree with this categorization needs made by Ching? Yes, because is very comprehensive and talks about the actual needs of architecture. Ching has studied very well these needs and by incorporating the city, the people and the structure of buildings in the same place.

Can you explain each of them? Needs of people: People have three basic needs. The first one are the ones physiological that are about providing adequate air, livable temperature, and the basic hygiene facts that make a space comfortable. The second one are the ones psychological, that take care of the sense of safety, privacy, and it most go with the personality of the ones who live inside to support their ego and self-esteem. And there the sociological needs that most provide spaces for the interaction with others. Needs of the building: The building itself also has five different needs. It must be able to protect all the contents inside and it should resist extremes weather conditions and earthquakes and fires. The weight of the building should let it stand up by itself including all the things that it contents. The insides of the building should be comfortable in order to keep appropriate living conditions in terms of humidity, air circulation and lighting. It also must allow a good entrance or exit of both materials and people. The distribution of the energy, information and different materials should be well balanced. Needs of context: The culture involves five categories of needs: the ones cultural that means that a building must be related with the other ones around it by the dominating culture, including historical, religious and political elements; the ones environmental that means that the building shouldn't be isolated of its surroundings and must consider the environmental impact that its hole presence means; the ones of communication that treat about the connections with electrical power sources, telephone lines and ways of transportation; the ones economical, these mean that it shouldn't be too expensive to deal with all the changing needs; and the ones of flexibility which mean that the building should be able to adapt to the changing needs of the people.

Are these needs similar for urban planners? I think that yes, because urban planner is who studies all of the real needs of the cities and the people. He searches harmony and stability in the city connecting the environment. Without the urbanism the cities wouldn't work correctly.
