Green Building – Sustainable Construction:

The architectural design can allow that the building gets a better energy and environmental performance::

- Architecture environmentally efficient, maximizing passive characteristics with good orientation, sunshine, shading, interior atrium, etc., allows better natural lighting and vetilation and requires less mechanical equipment for HVAC and lighting.

- Good mechanical equipment for HVAC and lighting, improves energy demand and efficiency.

- Adding sustainable architectural desgin to efficent mechanical equipment, means large energy savings and reduction of emmissions. A building with sustainable architecture and construction, through its entire life cycle shoud:

- Have an efficient energy consumption: consuming less without reducing quality, self-generation, co-generation, and using alternative energy sources,

- Reduce potable water consumption: rationalize, treat, recirculate,

- Minimize the use of non-renewable materials:

Reduce + Reuse + Recycle,

- Improve the interior environmental quality,

· Avoid environmental loadings or impact to the eco-systems.

In summary, more quality of life with less economic and material consumption. To achieve that is necessary to organize multidisciplinary teams from the earliest stages of the project development. Examples implemented in Chile demonstrate that it is possible.
