The recently upgraded Back-of-the-Envelope Calculator is more versatile as well. Not only can you see real-time energy connections, but you can calculate total CO 2 emissions for a building from both electricity and gas consumption. 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. When it comes to understanding energy efficiency opportunities, it’s useful to see how changing one component affects the whole.Įnergy 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.
Free tool shows energy interactions in buildingsĮnergy consumption in buildings is a complicated set of interactions among building components.
