Policy Analysis Modeling System (PAMS) provides robust techno-economic analysis to support energy efficiency standards and labeling programs. PAMS is an Excel workbook designed to give first-order policy impacts projections with a minimum of preparatory research on the part of local policymakers. The tool can be used out of the box to estimate costs and benefits of different S L policies for over 150 countries. Advanced users can improve the accuracy of estimates by customizing the tool with any country-specific data that are available.
