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.

In Onyx we have developed another tool in order to allow customers calculate buildings impact on the environment and its capacity to generate energy according to its placement, orientation, elevation, etc. You can try it here and check out how much you could be saving!
