advocating construction of superior buildings while maintaining simplicity and
applicability of the buildings in Japan and Asia.
CASBEE is composed of four assessment tools, CASBEE for predesign, for new
construction, for existing buildings, and for renovation which along with the other
tools for special purposes are called CASBEE Family.
CASBEE for predesign (underdevelopment) assists professionals who are
involved in planning stage of building to understand issues such as environment
impacts of the project. It also helps them to evaluate the environmental performance
of the project at the predesign stage.
CASBEE for new construction helps architects and engineers to improve the
building energy effi ciency by implementing the recommended strategies in this tool
during its design process.
CASBEE for renovation introduces the building managers to methods of provid-
ing building operation monitoring and commissioning for the existing buildings.
The other CASBEE tools which are designed for specifi c purposes are CASBEE
for detached houses, for temporary construction, brief versions, local government
versions, for heat island effect, for urban development, and for cities.
CASBEE system has been developed based on assessment of two distinct cate-
gories of (1) positive impact of the building system inside the boundary of the build-
ing site, and (2) negative effects of the building system outside the building site
boundary. To evaluate the positive impacts inside the building system boundary,
CASBEE focuses on quality of the building performance, quality of indoor environ-
ment, quality of service and quality of the outdoor environment at the building site.
On the other hand to evaluate the negative effects of the building system outside of
the building system boundary, CASBEE assesses the environmental load, energy
consumption, use of material and resources and outdoor environment outside the
building system boundary.
CASBEE system uses these two overall assessments to defi ne the indicator of
Building Environmental Effi ciency (BEE) based on the ratio of the assessment of
total “Q” to assessment of total “L,” or ratio of the quality of the building to the
environmental effects of the building.
CASBEE ranks the buildings based on one of the following categories of excel-
lent (S), very good (A), good (B+), rather poor (B−), and poor (C).
The indicator BEE for a poor building is anything below 0.5, for a rather poor
building is anything between 0.5 and 1, for a good building is anything between 1
and 1.5, for a very good building is anything between 1.5 and 3, and for an excellent
building anything above 3.

Other Sustainability Scoring Tools
As it was briefl y mentioned earlier in this topic in different countries some other
sustainability scoring tools have been developed which are custom made for the
countries of interest. Some of these systems and the countries that using these tools
are Green Globe for Canada, Green Star for Australia, HK-Beam for Hong Kong,
