These applications currently are LEED for New Construction (and major renova-
tions), for Existing Buildings (operations and maintenance), for Core and Shell
development, for Schools, for Retail, for Healthcare, for Commercial Interiors, for
Neighborhood Development and for Homes.
In general and similar to other sustainability scoring systems all the different
LEED standards are targeting subjects such as site sustainability, water use manage-
ment, energy and atmosphere, material election, and indoor air quality.
In LEED 2009 for new construction and major renovations achieving a maxi-
mum total of 110 points is possible, which a minimum of 40 points is required for
certifi cation. Also a minimum of 50, 60, and 80 points are respectively required for
a silver, gold and platinum level of certifi cation.
In site sustainability section means of improving the building by controlling
effects of functions such as construction activity pollution, public transportation,
storm water quantity and quality control, heat island effect and light pollution reduc-
tion are discussed. Advocating use of low emitting and fuel-effi cient vehicle, lower-
ing the number of parking space capacity to force public transition, and use of
maximum open spaces are discussed here as well. In this section 1 prerequisite and
a total of 26 credit points are possible to be achieved.
Subjects of discussions in water effi ciency section are means of reduction of water
use, innovative wastewater technologies, and process water use reduction. In this sec-
tion one prerequisite and a total of ten credit points are available for achieving.
In energy and atmosphere section attention is focused on commissioning of the
building, minimum energy performance, refrigerant management, on-site renew-
able energy and measurement and verifi cation of the consumed energy. In this sec-
tion 3 prerequisites and a total of 35 credit points are available for achieving.
In material selection section directions for using proper material for construction
is discussed. Storage and collection of recyclables, construction waste management,
recycled contents, regional materials, rapidly renewable materials and certifi ed
wood are subjects of discussion in this section. In this section 1 prerequisite and a
total of 14 credit points are available for achieving.
Finally indoor environment quality section is concerned with subjects such as
minimum indoor air quality, construction indoor air quality management during
construction and before occupancy, low emitting materials, occupant comfort
design, controllability and verifi cation, lighting controllability, and daylight. In this
section 2 prerequisites and a total of 15 credit points are available for achieving.
There are also two additional sections of innovation and design process and
regional priority for a total of ten extra bonus points.

CASBEE
Comprehensive Assessment System for Built Environment Effi ciency (CASBEE) is
a measure to promote sustainability that is developed for the state of Japan in 2001.
