The LEED V4 Guidebook said "For LEED, the project team must take into account the entire building structure and
enclosure, from design to demolition for an assumed 60-year service life."

My first question is, does this mean I have to include the calculated energy usage for 60 years of both the proposed and baseline building?

My second question is, do I have to complete every impact measures of the LCA even though I have saved 10% for the other three measures? (e.g. I have not calculated the impact of ODP and Formation of tropospheric ozone, but I have calculated and gained savings for the other impact measures)

Thanks so much in advance.
Best regards.
