U.S. OpenLabs - Software Tools
(Redirected from Gateway:U.S. National Labs/Computer Modeling Software)
What software and information is available to help screen and design clean energy projects or systems in my country?
There are a number of tools and models developed by the US National Labs which can be used to assist government officials, private sector, project developers and civil society in analyzing the optimal application of clean energy technologies. Many of the tools and models presented here are freely accessible and are adaptable to differing international circumstances, however, because many of the tools were developed for use in the U.S. this always an important consideration. Resources such as presentations, user manuals and other interactive media are available to allow for distance-based learning and application of these tools throughout the world.
Energy System Planning
- Energy and Power Evaluation Program (ENPEP-BALANCE): ENPEP-BALANCE is a software tool developed at Argonne National Laboratory that allows users to evaluate the entire energy system (supply and demand sides) and the environmental implications of different energy strategies.
- MARKet ALlocation (MARKAL): MARKAL is a computer-driven, dynamic optimization model that uses upwards of 10,000 equations and constraints to foster strategic energy planning developed at Brookhaven National Laboratory.
- Regional Energy Deployment System (ReEDS): Regional Energy Deployment System (ReEDS) is a multiregional, multitimeperiod, Geographic Information System (GIS), and linear programming model of capacity expansion in the electric sector of the United States.
- Stochastic Energy Deployment System: The Stochastic Energy Deployment System (SEDS) model is a capacity-expansion model of the U.S. energy market. The model uses five-year time periods from 2005 to 2050. SEDS can be operated either deterministically or stochastically.
Energy Efficiency Tools
- Advanced Process Engineering Co-Simulator (APECS): APECS, developed by the National Energy Technology Laboratory (NETL) and its R&D collaboration partners, is innovative enabling software that combines steady-state process simulation with computational fluid dynamics (CFD) models and reduced-order models (ROMs) for optimization of overall plant performance with respect to complex thermal and fluid flow phenomena. Built on the process industry CAPE-OPEN (CO) standard and the integrated access, workflow, and data services of the ANSYS® Engineering Knowledge ManagerTM (EKMTM), APECS enables the process and energy industries to address the challenge of designing complex next-generation plants with high efficiencies and near-zero emissions.

- Cool Roof Calculator: Cool Roof Calculator developed at the Oak Ridge National Laboratory is used to estimate and cooling and heating savings from using flat roofs and non-black surfaces.
- EnergyPlus: EnergyPlus is a software tool used to model heating, cooling, lighting, ventilating, and other energy flows as well as water in buildings.
- Policy Analysis Modeling System (PAMS): PAMS provides an easy-to-use software tool to help local policymakers assess the benefit of standards and labelling programs, and to identify the most attractive targets for appliances and efficiency levels.
- Cost of Renewable Energy Spreadsheet Tool
- RETFinance: RETFinance is used to calculate cost of energy of renewable electricity generation technologies such as biomass, geothermal, solar, and wind and was developed at NREL.
- Scenario Evaluation, Regionalization & Analysis (SERA): SERA (Scenario Evaluation, Regionalization & Analysis) is a geospatially and temporally oriented infrastructure analysis model that determines the optimal production and delivery scenarios for hydrogen, given resource availability and technology cost.
