Designing sustainable buildings calls for a detailed understanding of local
cultures and environments, quality standards, environmental regulations,
safety standards and building codes.  
There are many sustainability rating systems and certifications in the world
today. The most common systems will be listed below:
LEED – Leadership in Energy and Environmental Design
It is one of the most popular rating systems and green building certification
programs around the world. LEED was developed by nonprofit
organization Il.S. Green Building Council   ( USGBC). It is a voluntary,

owners, designers and real estate professionals to transform the
construction environment into a sustainable one. Green building practices
can considerably reduce or eliminate negative environmental impacts and
