Basic Parameters Screen

The document provides a detailed technical walkthrough of the Settings menu in LEAP, covering the Scope & Scale, Years, Calculations, Costs, Optimization, IBC, Internet, Mapping, Folders, and Scripts tabs. It explains how users can enable specific analysis modules—such as energy demand, transformation, and environmental effects—and configure critical parameters like base years, discount rates, and optimization solvers. The guide also details the integration of the Impact Benefit Calculator (IBC) for health and climate impact modeling and the use of GIS shape files for geographical mapping of results.

• The Scope & Scale tab allows users to enable or disable various analysis modules, including energy demand, transformation and resources, land-use change, costs, and energy/non-energy effects. Specific optional analyses include 'Affordability Analysis' for low-income or rural households and 'Calculate Useful Energy for All Demands' for Sankey Diagrams.
• LEAP's temporal settings include the Base Year (first year of data), End Year (final year calculated), and First Scenario Year. The 'First Depletion Year' is used to track when resource reserves are depleted by primary fuel consumption.
• The Costs tab enables social cost-benefit analysis with two boundary options: 'Full system costing', which covers the entire area, and 'Restricted costing boundary', which limits costs to a specific module to avoid difficulties in capturing upstream costs like coal mining or oil refining.
• Optimization settings allow for the inclusion of emission constraints and the selection of solvers. Supported solvers include GLPK, Cbc, HIGHS, CPLEX, GUROBI, MOSEK, and XPress.
• The Impact Benefit Calculator (IBC) module calculates health impacts, such as premature mortality from indoor and ambient air pollution, and crop damage from ozone. It can utilize relative risk functions from the Global Burden of Disease (2010, 2015, and 2019) and integrate ECLIPSE scenarios from IIASA for 'Rest of World Emissions'.
• Geographical mapping is supported through the use of standard GIS shape files. The 64-bit version of LEAP can create and display maps with up to 300 x 300 cells, while the 32-bit version is limited to 50 by 50 cells.
