  * The structure scale expresses the structural type of the main building and the number of floors above and below ground. The structural categories are as follows.

SRC: Steel-framed reinforced concrete
RC: Reinforced concrete
S: Steel framed

BEE (Building Environmental Efficiency) Calculated from the CASBEE evaluation Q (elements relating to the environmental quality/performance of the structure) and L (elements relating to the external environmental load of the structure). BEE = Q/L
CASBEE overall evaluation Depending on the BEE score, structures are given one of five rankings, C, B-, B+, A, and S. B+: 1.0 - 1.5, A: 1.5 - 3.0, S: 3.0 or more
LCCO2 reduction performance Shows the LCCO2 reduction performance of the buildings compared to a standard model of the same building type and scale on the green buildings check sheet.
Environmental friendliness Shows the level of consideration for each environmental item based on the green buildings policy (rated on a scale of 0 - 10, with a perfect score being 10 out of 10 for each item).
Standard model: Standard building based on the Guidelines for Energy Conserving Architecture (1980).The structure scale expresses the structural type of the main building and the number of floors above and
