CATEGORIES

The rating system is composed of prerequisites (mandatory) and credits (optional) divided into 9 categories:

IP - INTEGRATED PROCESS
Utilize integrative approaches and techniques for green design and construction.
LT - LOCATION AND TRANSPORTATION
Promote a compact development, through the choice of building location, and enhance alternative transportation.
SS - SUSTAINABLE SITES
Restore project site elements, integrate the site with local and region ecosystems, preserve the biodiversity.
WE - WATER EFFICIENCY
Water efciency, reduce potable water use, promote the use of nonpotable and alternative sources of water.
EA - ENERGY AND ATMOSPHERE
Energy use reduction, energy-efcient design strategies, promote renewable energy sources and reduce greenhouse gases emissions and fossil fuel uses.
MR - MATERIALS AND RESOURCES
Selection of resources and transparency in processes to improve the knowledge and the impact of building’s components on health and environment. Waste Management and Life Cycle Approach.
EQ - INDOOR ENVIRONMENTAL QUALITY
Indoor air quality, thermal and visual comfort and occupant’s satisfaction.
IN - INNOVATION
Recognize projects for innovative building features and sustainable building practices and strategies.
RP - REGIONAL PRIORITY
Applies to some environmental issues that are particular to a locale.
THE CONTRIBUTION OF SELECTED PRODUCTS, PROCESSES AND SERVICES IS FUNDAMENTAL FOR DEVELOPERS ADDRESSING PRINCIPLES AND SUSTAINABILITY INDICATORS FOR ORIENTING INVESTMENTS. PRODUCTS AND PROCESSES CONTRIBUTE TO THE OVERALL PERFORMANCE OF BUILDINGS AND TO QUALITY OF BUILDING INDUSTRY.

LEED®

The LEED rating  systems  aim  to promote a transformation of the construction industry through strategies designed to achieve seven goals:

• to reverse contribution to global climate change
• to enhance individual human health and well-being
• to protect and restore water resource
• to protect, enhance, and restore biodiversity and ecosystem services
• to promote sustainable and regenerative material resources cycles
• to build a greener economy
• to enhance social equity, environmental justice, community health, and quality of life


LEED defines a standard for measuring building sustainability, seeks to optimize the use of natural resources, promote  regenerative and restorative strategies, minimize the negative environmental and human health consequences of the building industry. The standard promotes an integrative design and an integration of the skills.

 


CERTIFICATION LEVELS

 

he rating  system  has 4  leveles of certification,  depending  on  the overall performance achieved:
