| Summary: | CASBEE (Comprehensive Assessment System for Building Environmental
Efficiency) is an environmental labeling method for buildings, based on assessment of the
environmental performance of buildings. In CASBEE, BEE (Building Environmental Efficiency)
was developed as a new indicator for assessment following the concept of eco-efficiency. With
the increasing BEE value, the total environmental performance of buildings is labeled from the
highest performance. The framework of basic and extended CASBEE tools as a structured
assessment system is called the “CASBEE family”. CASBEE consists of a set of four basic
assessment tools, namely “CASBEE for Pre-design” (CASBEE-PD), “CASBEE for New
Construction” (CASBEE-NC), “CASBEE for Existing Building” (CASBEE-EB) and “CASBEE for
Renovation” (CASBEE-RN). These correspond to the individual stages of the building's
lifecycle. There are also needs for detailed assessment targeting specific environmental
aspects. “CASBEE-HI,” as an extended tool, assesses efforts made in buildings to alleviate the
heat island effect. A new tool called “CASBEE for Urban Development” (CASBEE-UD) is
developed for assessment of a group of buildings. In Japan, approximately 500,000 detached
houses are constructed every year. In order to improve the quality of houses, “CASBEE for
Home” was introduced in 2007. Some local authorities introduced CASBEE into their building
administration as assessment methods for their sustainable building reporting systems. This
requires building owners to submit a planning document assessing the environmental
performance of their buildings to the authorities. In April 2004, the city of Nagoya introduced
“CASBEE Nagoya”. Introduction of CASBEE followed in the city of Osaka, Yokohama, Kyoto,
and other municipals. These local systems require some modification in CASBEE to reflect
their local characteristics, such as climate and prioritized policies. |
