Green Star FAQs
Is a Hazardous Materials Survey still required when all contaminated structures were demolished?
No.
Under Green Star Buildings, projects that can demonstrate that all contaminated structures or buildings were demolished and fully removed do not need to conduct a Hazardous Materials Survey when targeting the Banned or Highly Toxic Materials Minimum Expectation Criteria. The intent of the criteria is to ensure occupants are not exposed to banned/toxic materials where existing building elements are retained. Projects that do not have existing buildings on the site at the time of purchase or are not retaining any existing buildings on the site are exempt from the Banned or Highly Toxic Materials criterion.
Equally with the same intent, under Design & As Built, the credit pathway 24.2B Hazardous Materials may only be targeted where existing buildings or structures are retained. Where all existing buildings and structures are demolished and none are retained, the 24.2B Hazardous Materials cannot be targeted.
