Does anybody know why this form wants a breakdown of new construction, existing renovated, and existing unrenovated? We are working on a 20 year old building, and over 20 years I am sure that various tenants have come and gone, and that walls or ducts have changed over time. My question: how is USGBC using this information? I could guess at the square feet that have been renovated over time, but it seems irrelevent (?). Thank you, I could not find another thread on this.
