For Option 2, demonstrating that 25% of the cost of the project materials meet REACh compliance, There is a requirement that only 30% of these material costs can be attributed to the structure or enclosure. Although in 2017 this was revised to ‘allow project teams to use include more than 30% if they document that their overall materials budget is more than 30% invested in the structure and enclosure.’ How is this documented and what is the new requirement?
Thank you in advance.
