Carbon Assessment |
USGBC will provide the project team with a 10-year projected carbon assessment for the project. The assessment will use data from the following:
-
EAp1: Estimated Energy Use and Operational Carbon Projection
-
EAp5: Fundamental Refrigerant Management
-
MRp2: Quantify and Assess Embodied Carbon
-
LTc2: Transportation Demand Management (optional)
REQUIREMENTS EXPLAINED
This prerequisite requires a 10-year carbon assessment of all emissions within the project boundary but does not require any additional data to be entered beyond what is already required by the three related prerequisites and the optional credit, if pursued.
Until recently, most projects only considered GHG emissions from operational energy use, if emissions were considered at all. However, as it has become increasingly clear that emissions from construction (“embodied carbon”) and refrigerants can also be quite considerable, LEED v5 has introduced prerequisites to assess carbon emissions from all three sources. This unifying prerequisite enables project teams to compare their sources of emissions and see which are more or less significant. The integrative process prerequisite gathers data from the three related prerequisites ( EAp1: Estimated Energy Use and Operational Carbon Projection, EAp5: Fundamental Refrigerant Management, MRp2: Quantify and Assess Embodied Carbon ), and optionally from LTc2: Transportation Demand Management, if that credit has been pursued, and provides project teams with a report and visualization so that they can see how their different
