Hello,

following situation: We have a CS project, where we will have a new construction part and a building renovation. In the existing part the windows will be salvaged, get new heat-insulating glass (instead of single glazing) and will be reused. Are these "upgraded" windows eligible for MRc3 as we do not have the chance to take them into account for MRc1?

I am not sure if I can calculate with these windows in MRc3 as on the one hand we do not have a different purpose or location, but on the other hand the Reference Guide (p. 365) states: "Other reused materials found on-site. Components that are retained and continue to serve their original function, such as door hardware, are eligible for this credit.".

Could anyone help? Thanks!
