Conclusion If Solar roof capacity is fully used, it would meet 8.2% of the university s electricity consumption. 262 acres of solar PV land space is required to meet all the university s electricity needs. Leveraging solar roof is valuable in decreasing GHG emissions. If fully capitalized, the maximum GHG from purchased electricity reduced by solar roof is 15%. Solar PV does not greatly impact the %GP in the grid for the university when it replaces purchased electricity since the grid in NYUP is low carbon intensity. However, it is valuable when it replaces electricity generated from cogeneration as cogenerated electricity is produced with natural gas. Further study is recommended to analyze the GHG from cogeneration, economics of the solar incorporation, 13
