* LEED (Leadership in Energy & Environmental Design) is an environmental assessment system developed by the U.S. Green Building Council (a nonprofit organization). LEED has been emerging as a global standard. There are four certification levels (Certified, Silver, Gold, and Platinum) based on the total points earned for seven assessment items (site, water, energy, material, air quality, new technology, and local characteristics).
* CASBEE (Comprehensive Assessment System for Built Environment Efficiency) is the most highly-recognized system in Japan for comprehensive assessment of environmental performance of buildings. This certification system evaluates buildings whose environmental quality and performance (e.g. interior comfort, consideration to landscape) are high with less environmental impact (load) achieved by energy/resource conservation and recycling.
(Applications have been made to LEED and CASBEE as of November 2015.)
