Origin of vertical gardens

A vertical garden consists of upholstering walls and roofs with plants that grow without need of soil. One of the objectives of its use is to optimize space in cities.

Its origin was neither accidental nor the result of the work of individuals or companies. Many civilizations and countries have used it for its multiple benefits throughout history, we can find examples in Tokyo, America, or Europe.

It should be noted that one of its precursors today is Patrick Blanc, who has developed and innovated on this subject, becoming one of the reference points today.

Evolution of vertical gardens

Nowadays, this type of decoration is part of the culture surpassing mere fashion, so France is the first country in the world to adopt such legislation, and others are expected to copy.” It is mandatory that some European capitals such as Copenhagen already have.

With this legislation, is to the effect that the roofs on the buildings with plants and shrubs, help to absorb rainwater and reduce runoff, preserve the waterproofing, will provide green space to urban areas that will facilitate the reduction of the effect of urban “heat island”, due to the absorption of heat during the day and stored in large concrete and brick, whose nature ceramic conducive, and release it slowly at all times.

Health benefits:.

  • The vegetation traps dust and generates oxygen.
  • A 4-storey building with a front carrying this system filters 40 tons of harmful gases and 15 kg of heavy metals per year.
  • (Darlington, 2001) It improves the performance and reduces discomfort of people who have vegetation in their workplace.
  • The plant insulator reduces noise pollution by up to 10 decibels.

This has only just begun. Is it a trend or is it a culture that is engulfing in today’s society? Internalism is nothing more than a culture, a way of understanding spaces and new uses, new ways of making the usual simpler, more comfortable and more attractive.
