Ozone-depleting compounds
. Eliminate the use of ozone-depleting
compounds where alternative environmentally preferable prod-
ucts are available, consistent with either the Montreal Protocol and
Title VI of the Clean Air Act Amendments of 1990, or equivalent
overall air quality benefits that take into account life cycle impacts.
8.3.2 Design Considerations and Enforcement
During the design stage of buildings projects that require and use energy
extensively, the designers should follow all known techniques, options and
codes to end up with an energy-efficient design.
Rating systems are groups of requirements for projects that want to
achieve LEED certification. Each group is geared toward the unique needs of
a project or building type.
LEED is flexible enough to apply to all project types including healthcare
facilities, schools, homes and even entire neighbourhoods. The rating system
selection guidance will help you determine which specific rating system is
right for your project.
Projects earn points to satisfy green building requirements.
Within each of the LEED credit categories, projects must satisfy prerequi-
sites and earn points. The number of points the project earns determines its
level of LEED certification. The main credit categories are as follows.
1.
Sustainable site credits
encourage strategies that minimise the impact
on ecosystems and water resources.
2.
Water efficiency credits
promote smarter use of water, inside and out,
to reduce potable water consumption.
3.
Energy and atmosphere credits
promote better building energy perfor-
mance through innovative strategies.
4.
Materials and resources credits
encourage using sustainable building
materials and reducing waste.
5.
IEQ credits
promote better indoor air quality and access to daylight
and views.
Additional LEED for Neighbourhood Development credit categories are
1. Smart location and linkage credits promote walkable neighbour-
hoods with efficient transportation options and open space.
2. Neighbourhood pattern and design credits emphasise compact,
walkable, vibrant, mixed-use neighbourhoods with good connec-
tions to nearby communities.
3. Green infrastructure and buildings credits reduce the environmen-
tal consequences of the construction and operation of buildings and
infrastructure.
