Appendix: Models and Tools
ETA’s divisions support the development and use of a wide range of tools, models, software, and
data resources designed to inform and assist policymakers, support innovation in industry, and
advance the impact of research in laboratories and academia. These models and tools support
advanced research across many sectors, including buildings, industry, transportation, and power
utilities, and are key instruments for helping ETA accomplish its Strategic Initiative goals.
Energy Usage and Performance
Benchmarking and Energy Saving Tool for LowCarbon Cities (BEST Cities): Provides analysis of local
energy and carbon performance and recommends
strategies to achieve energy savings and citywide carbon
emissions reductions.
Bottom-Up Energy Analysis System (BUENAS):
Estimates global energy-efficiency potential for
residential, commercial, and industrial equipment.
Building Energy Data Exchange Specification (BEDES):
A dictionary of terms, definitions, and field formats that
help facilitate the exchange of information on building
characteristics and energy use.
Building Performance Database (BPD): Allows
empirical analysis and peer comparison of the energy
performance of commercial and residential buildings.
Includes energy use and characteristics on more than
1 million buildings in the United States.
Commercial Building Analysis Tool for EnergyEfficient Retrofits (COMBAT): Analyzes commercialbuilding retrofit energy savings and investment costeffectiveness.

Commercial Building Energy Saver (CBES): A web
application providing detailed whole building energy
retrofit analysis using EnergyPlus™ modeling, smart
meter analytics, benchmarking, and a comprehensive
energy conservation measures database.
City Building, Energy, and Sustainability (CityBES):
A web-based data and computing platform to support
city and district scale building energy efficiency,
decarbonization, and climate resilience.
Eco and Low-Carbon Indicator Tool for Evaluating
Cities (ELITE Cities): Evaluates the performance of
Chinese cities by comparing them against benchmark
performance goals. The tool measures progress on
33 key indicators selected to represent priority issues
within eight primary categories. Future projects will
continue to better reflect the needs of city energy
planners and provide benchmark data, policy analysis,
and action plans for sustainability.
Energy Efficiency Assessment and Greenhouse Gas
Emission Reduction Tool (EAGER): A suite of tools that
provide information on the energy-savings potential
and cost of energy-efficiency technologies for various
industries, including steel, pulp and paper, and textiles.
Energy Performance Improvement (EnPI) Lite:
Estimates energy savings relative to relevant variables
like production levels and weather.
EnergyPlus: A new-generation building energy
simulation program based on DOE-2 and BLAST, with
numerous added capabilities.
GenOpt®: An optimization program for the minimization
of a cost function that is evaluated by an external
simulation program, such as EnergyPlus, TRNSYS,
SPARK, IDA-ICE, or DOE-2.
Green Resources and Energy Appraising Tool
(GREAT): Analyzes a city’s greenhouse gas inventory,
providing scenario generation of future energy and
emissions and evaluation of the impacts of different
policies.
Home Energy Score: Provides homeowners, buyers,
and renters directly comparable and credible
information about a home’s energy use. The Home
Energy Score Report estimates home energy use and
associated costs, and provides energy solutions to costeffectively improve the home’s efficiency.
Home Energy Saver: Designed for the general public,
Home Energy Saver allows people to rate their home’s
energy use. It provides suggestions for energy savings
based on information input by the user. It includes
blogs, videos, and case studies.
Industry Sector Energy Efficiency Modeling (ISEEM):
Provides an industry sector energy supply–demand
planning model, including commodity and carbon
trading as viable alternatives to emission reduction.
Laboratory Benchmarking Tool: A benchmarking
database tool that allows laboratory owners to compare
their facility’s performance to similar facilities and help
identify potential energy-saving opportunities.
Manufacturing Structure and Energy Research
(MASTER): Helps users understand how different factors
(production growth, industry structural change, and
energy intensity change) influence industrial energy use
trends over time.
Modelica “Buildings” Library: A free, open-source
library for modeling of building energy and control
systems using the equation-based, object-oriented
Modelica language.
National Impact Analysis (NIA): Assesses aggregate
impacts of potential efficiency standards for appliances
and commercial equipment.
Policy Analysis Modeling System (PAMS): Provides
robust techno-economic analysis to support energy
efficiency standards and labeling programs.
Prototype Energy Models for Laboratories, Data
Centers and Tall Buildings: New prototype building
models in OpenStudio OSM or EnergyPlus IDF forms for
modeling energy efficient design and technologies for
laboratories, data centers, and tall buildings.
