Paragraph 3

=== **For centiries, glass has been used as an exclusive construction material, today the production of glass has been easier, which makes it more accessible, but still maintains its beauty. ** ===

===** In Caracas, glass has been used in many ways, from simple windows in houses to all-glass facades of buildings. Glass domestically is very useful because it allows a clear view through the windows and protects the house from the elements. The use of glass in buildings at the macro scale can be successful in some specific cases, it is not so when it comes to a tropical climate such as Caracas, which is why glass is usually not recommended to completely cover facades. The inappropriate use of glass in big buildings or skyscrapers would mean a temperature increment inside the building and naturally an increase in the use of air conditioning. This is why we must take into account climatic conditions in the region before deciding to use glass in a big measure. **=== ===** An example of the bad use of glass in Caracas city is el Cubo Negro. This building is completely cover ed with black glass, and it is so bad to the environment in 2 aspects, the energetic extra waste of the air conditioning and the damage to vegetation caused by the sun reflection. **===
