Bottom-Up Energy Analysis System (BUENAS)

Bottom-Up Energy Analysis System (BUENAS)
The Bottom-Up Energy Analysis System (BUENAS) estimates global energy-efficiency potential for residential, commercial and industrial equipment.

Bottom-Up Energy Analysis System

The Bottom-Up Energy Analysis System (BUENAS) projects appliance energy demand and emissions through 2030 globally and by country. BUENAS provided input to IEA World Energy Outlook 2012 and was featured in IIASA Global Energy Assessment.

BUENAS projects appliance energy demand and emissions through 2030 globally and by country. The current version of BUENAS covers 13 major national economies that account for ~80% of global energy demand and covers 15 building and industrial appliances and equipment categories, for a total of~200 equipment and country combinations.

Energy Savings Potential by Appliance in 2030

An analysis across several economies. ECEEE Summer Study, France.

BUENAS simulates policy scenarios such as:

  • Best Practices — Identifies 'achievable' efficiency targets based on alignment of Minimum Energy Performance Standards (MEPS) across regions to model harmonization potential
  • Cost-Effective Potential — Models economic potential of high-efficiency appliance and equipment by integrating BUENAS and Global Energy Efficiency Cost (GEEC) Database developed at Berkeley Lab
  • Best-Available Technology — Characterize Most Aggressive efficiency scenario representing technical potential
