Energy Center Launches Back-of-the-Envelope Calculator

Craig DiLouie May 19, 2010

Energy consumption in buildings is a complicated set of interactions among building components. When it comes to understanding energy efficiency opportunities, it’s useful to see how changing one component affects the whole. Energy engineers at the Energy Center of Wisconsin developed the Back-of-the-Envelope Calculator to provide greater initial insight into the energy usage and environmental impacts of a proposed commercial building project. The calculator is available for free download and lets you see real-time energy connections among building components, isolate the effects of a change to a single energy parameter or produce concept-level energy estimates. Not only can you see real-time energy connections, but you can calculate total CO2 emissions for a building from both electricity and gas consumption. The recently upgraded Back-of-the-Envelope Calculator is more versatile as well. It can now be used to analyze multiple-story buildings, instead of just a single-story building.
