Bottom-Up Energy Analysis System - Methodology and Results

BUENAS is an end-use energy demand projection model developed by Lawrence Berkeley National Laboratory (LBNL) in the United States of America with support from the Collaborative Labeling and Appliance Standards Program (CLASP), the International Copper Association (ICA), and the United States Department of Energy (USDOE). As the name suggests, BUENAS is a tool to model energy demand by various types of energy consuming equipment and aggregate the results to the end use, sector or national level. BUENAS is designed as a policy analysis tool which creates scenarios differentiated by the level of actions taken – generally toward higher energy efficiency. Impacts of policy actions towards market transformation are calculated by comparing energy demand in the “business as usual” case to a specific policy case. BUENAS shares elements with a variety of models, including models of energy savings supporting the USDOE’s appliance standards program. The characteristics that distinguish BUENAS are that it covers multiple countries, models energy demand at the technology level, and projects efficiency improvement based on specific targets known to be achievable.
