Building-above-land for protecting vegetation and environment

摘要

A change from building-on-land to building-above-land reserves land (12) for vegetation (16A, 16B, 16C) the earth's solar system, and natural environment. High columns (26A, 26C) are mainly for short vegetation (16B) to grow under buildings (18A, 18C, 18D, 18E). Low columns (26B) are mainly for tall and extra tall vegetation (16A, 16C) to grow over buildings (18B, 18C, 18D, 18E). High columns (26A, 26C) and low columns (26B) can support buildings (18C, 18D) together and reserve land (12) for different vegetation (16A, 16C, 16B). Columns (26A, 26B, 26C) can be developed into various supporting structures (52A, 52B, 52C, 52D) and supporting-greenhouses (54A, 54B, 54C) that can create indoor ecosystem, reduce cost for heating, increase arable land in barren areas, and keep conventional building styles, conveniences and privacy. Substitutes (26E, 26D, 34″, 54D) are also available to support roads (24A, 24B) and building (18F). Columns can support most architectural structures, keep natural environment in cities, and reduce pollution and global warming. Building-above-land can attract people to live near working places, shorten commuting distances, cut budgets, and align human activities with the design of Mother Nature. Building-above-land is financially acceptable.
