Q&As

Q
1 Are the new standards applied to properties that have already been notified?
A

1 Since the evaluation will be based on the standards at the time of notification, there is no need to apply the new standards for notification of changes. It does not prevent notification of changes based on the evaluation under the new standard.

Q
2 Is CASBEE Yokohama [Detached House] also revised?
A

2 CASBEE Yokohama [Detached House] is not included in this revision of standards. In the future, when revising the standards for CASBEE Yokohama [Detached House], it will be announced separately on the website.

Q
3 Do you revise the standards for non-specific buildings (less than 2000m2) in the same way?
A

3 We will also revise the standards for non-specific buildings.
