Energy Center Launches Back-of-the-Envelope Calculator

Energy Center of Wisconsin

When it comes to building energy consumption, nearly everything affects everything. It's very difficult to get a feel for energy efficiency among the complicated interactions.

Our Back-of-the-Envelope calculator is a learning tool that allows anyone to interact with a building as an energy system. You can see real-time energy connections between building components, isolate the effects of changing a single energy parameter, or produce concept-level energy and CO2 emissions estimates.

You might be pondering these questions:

• What happens to cooling costs if I double my roof insulation?
• Does lighting efficiency also affect heating energy?
• Does it cost a lot to keep my building open longer?
• What if my building was made of glass?
• How much CO2 will this building produce annually?
