Audited planning profile
This shared daily profile applies a 3× editable baseline across 1 model period to the household gas change model.
Use the absolute difference for budgeting and the percentage difference for comparing impact. Define a consistent allocation rule so shared usage is not counted twice. Use a typical day and separately test peak or exceptional days.
Emission factors, lifecycle boundaries, grid mix, water stress and local waste treatment differ by source and location.
Use a dated, regional factor from an official inventory or recognized lifecycle dataset and state the boundary.
