Argonne’s Energy Efficiency Decision Support Calculator is a simple tool that small business owners can use to quickly analyze the high-level economic impact of investments in energy efficient products, retrofits or capital improvements. This tool requires minimal input data and is accessible to anyone, regardless of their experience with energy issues. It is intended to complement many of the more involved, technology specific calculators that are referenced in Argonne’s “Resources for Informed Small Business Energy Efficiency Decision Making.”

Hourly, whole-building energy analysis program calculating energy performance and life-cycle cost of operation. Can be used to analyze energy efficiency of given designs or efficiency of new technologies. Other uses include utility demand-side management and rebate programs, development and implementation of energy efficiency standards and compliance certification, and training new corps of energy-efficiency conscious building professionals in architecture and engineering schools.
Software environment that supports the integration of multiple building models and databases used by analysis and visualization tools, through a single, object-based representation of building components and systems. BDA (Building Design Advisor) acts as a data manager and process controller, allowing building designers to benefit from the capabilities of multiple analysis and visualization tools throughout the building design process. BDA is implemented as a Windows-based application. The current version includes links to a simplified Daylighting Computation Module (DCM), a simplified Electric lighting Computation Module (ECM), and the DOE-2.1E Building Energy Simulation software.
Berkeley Lab WINDOW is a publicly available computer program for calculating total window thermal performance indices (i.e. U-values, solar heat gain coefficients, shading coefficients, and visible transmittances). Berkeley Lab WINDOW provides a versatile heat transfer analysis method consistent with the updated rating procedure developed by the National Fenestration Rating Council (NFRC) that is consistent with the ISO 15099 standard. The program can be used to design and develop new products, to assist educators in teaching heat transfer through windows, and to help public officials in developing building energy codes.
THERM is a state-of-the-art computer program developed at Lawrence Berkeley National Laboratory (LBNL) for use by building component manufacturers, engineers, educators, students, architects, and others interested in heat transfer. Using THERM, you can model two-dimensional heat-transfer effects in building components such as windows, walls, foundations, roofs, and doors; appliances; and other products where thermal bridges are of concern. THERM's heat-transfer analysis allows you to evaluate a product's energy efficiency and local temperature patterns, which may relate directly to problems with condensation, moisture damage, and structural integrity.
OpenStudio is a cross-platform (Windows, Mac, and Linux) collection of software tools to support whole building energy modeling using EnergyPlus and advanced daylight analysis using Radiance. OpenStudio is an open source project to facilitate community development, extension, and private sector adoption.
OpenStudio Plug-in for Google SketchUp is an extension to Google’s popular 3D modeling tool that adds EnergyPlus context to the SketchUp program. The Plug-in allows users to quickly create geometry for EnergyPlus using the built-in functionality of Google SketchUp including existing drawing tools, integration with Google Earth, Building Maker, and Photo Match.
Open studio ResultsViewer displays EnergyPlus output in formats that are more useful than those available directly from the EnergyPlus engine.
OpenStudio RunManager is a tool for managing simulations spread across multiple computers or supercomputer cores. It currently supports EnergyPlus.
Work with the buildings industry to develop and maintain data, methods, and tools to understand and improve the sustainability of buildings at a fundamental level and continue to develop and support the U.S. Life Cycle Inventory (LCI) Database, which provides the starting point for LCA.
