This project information includes energy usage and cost savings as well as details behind the type of energy being saved and project description. Reports from this tool facilitate the process of aggregating annual cost and GHG reductions each year. e.) emissions were reduced in direct (Scope 1) and indirect (Scope 2) emissions.
