What is the LEED System?
Scores are tallied for different aspects of
efficiency and design in appropriate
categories. For instance, LEED assesses in
detail 1. Site Planning 2. Water Management 3.
Energy Management 4. Material Use 5. Indoor
Environmental Air Quality 6. Innovation
Design Process
LEADERSHIP in ENERGY and ENVIRONMENTAL DESIGN A
leading-edge system for certifying DESIGN,
CONSTRUCTION, OPERATIONS of the greenest
buildings in the world

Category 1 Sustainable Sites

• Reduce stormwater runoff to local water system.
• Improve the quality of stormwater runoff.
• Encourage carpooling and alternative
  transportation methods by providing preferred
  parking for carpoolers, installing bike racks and
  showers, and looking for opportunities to bring
  public transportation to the building.

8
Category 2 Water Efficiency

• Install low flow sinks, showers and water
  closets.
• Landscape with plants and grasses that are native
  to the local area so that irrigation can be
  minimized.

9
Category 3 Energy and Atmosphere

• Perform building commissioning.
• Reduce the buildings energy use by upgrading the
  mechanical systems.
• Use less harmful refrigerants in the HVAC system.

10
Category 4 Material Use

• Build with materials that have a high content of
  recycled material.
• Procure building materials from the local region.
• Reduce construction waste by recycling.

11
Category 5 Indoor Environment

• Use low VOC-emitting finish materials.
• Provide temperature and lighting controls to meet
  individual needs.
• Provide daylight and views to building occupants.

Green Buildings worldwide are certified with a
voluntary, consensus-based rating system. USGBC
has four levels of LEED.
