Sustainable SitesChoosing a building's site and managing that site during construction are important considerations for a
projects sustainability. The Sustainable Sites category discourages development on previously
undeveloped land; minimizes a building's impact on ecosystems and waterways; encourages regionally
appropriate landscaping; rewards smart transportation choices; controls stormwater runoff; and reduces
erosion, light pollution, heat island effect and construction-related pollution.
Water Efficiency
Buildings are major users of our potable water supply. The goal of the Water Efficiency credit category is
to encourage smarter use of water, inside and out. Water reduction is typically achieved through more
efficient appliances, fixtures and fittings inside and water-wise landscaping outside.
Energy & Atmosphere
According to the U.S. Department of Energy, buildings use 39% of the energy and 74% of the electricity
produced each year in the United States. The Energy & Atmosphere category encourages a wide variety
of energy strategies: commissioning; energy use monitoring; efficient design and construction; efficient
appliances, systems and lighting; the use of renewable and clean sources of energy, generated on-site
or off-site; and other innovative strategies.
Materials & Resources
During both the construction and operations phases, buildings generate a lot of waste and use a lot ofmaterials and resources. This credit category encourages the selection of sustainably grown, harvested,
produced and transported products and materials. It promotes the reduction of waste as well as reuse
and recycling, and it takes into account the reduction of waste at a products source.
Indoor Environmental Quality
The U.S. Environmental Protection Agency estimates that Americans spend about 90% of their day
indoors, where the air quality can be significantly worse than outside. The Indoor Environmental Quality
credit category promotes strategies that can improve indoor air as well as providing access to natural
daylight and views and improving acoustics.

LEED MEASURES

Locations & Linkages
The LEED for Homes rating system recognizes that much of a home's impact on the environment comesfrom where it is located and how it f its into its community. The Locations & Linkages credits encourage
homes being built away from environmentally sensitive places and instead being built in infill, previously
developed and other preferable sites. It rewards homes that are built near already-existing infrastructure,
community resources and transit, and it encourages access to open space for walking, physical activity and
time spent outdoors.
Awareness & Education
The LEED for Homes rating system acknowledges that a green home is only truly green if the people who
live in it use the green features to maximum effect. The Awareness & Education credits encourage homebuilders and real estate professionals to provide homeowners, tenants and building managers with the
education and tools they need to understand what makes their home green and how to make the most of
those features.
Innovation in Design
The Innovation in Design credit category provides bonus points for projects that use new and innovative
technologies and strategies to improve a buildings performance well beyond what is required by other
LEED credits or in green building considerations that are not specifically addressed elsewhere in LEED.
This credit category also rewards projects for including a LEED Accredited Professional on the team to
ensure a holistic, integrated approach to the design and construction phase.
Regional Priority
USGBCs regional councils, chapters and affiliates have identified the environmental concerns that are
locally most important for every region of the country, and six LEED credits that address those local
priorities were selected for each region. A project that earns a regional priority credit will earn one bonus
point in addition to any points awarded for that credit. Up to four extra points can be earned in this way. See
the Regional Priority Credits for your state
