CASBEE Family and tools

CASBEE is comprised of assessment tools tailored to different scales: construction (housing and buildings), urban (town development) and city management. These tools are collectively known as the CASBEE Family.

Tools for housing scale

1) CASBEE for New Detached Houses

This tool is used to assess the environmental performance of detached houses. The scoring criteria are simplified in anticipation of use by residents or small- and medium-sized building contractors.
CASBEE for New Detached Houses was developed in 2007. There are various stakeholders in the housing construction industry such as clients, architects, contractors, and builders. Therefore, "CASBEE for New Detached Houses" especially focuses on making its structure easy for users to understand. Among CASBEE tools, CASBEE for New Detached Houses was the first to introduce a new indicator of the five BEE ranks using the corresponding number of stars, in addition to the BEE chart. It includes 54 sub-criteria that have been modified from the other standards in Japan. These items for comprehensive assessment cover not only the house itself but also the outdoor space of the house, home appliances, information provided to the occupants from house suppliers, and the environmental strategies at the material production and construction stages.
