This fact sheet offers insight into how a net zero home can be both architecturally distinctive as well as be energy efficient and environmentally friendly.
Between 50% and 70% of the energy used in the average home is used for heating and cooling. Correcting air leakage and insufficient insulation can have a significant effect on your heating and cooling costs.
By sealing air leaks in your home, you can improve comfort, decrease drafts, and save energy. Attics, basements, and crawl spaces are the biggest sources of air leaks in the home.
The average duct system loses 12% or more of conditioned air due to leaks and poorly connected ducts. By properly sealing ducts, you can reduce energy loss and lower your energy costs.
An energy audit of your home can help you to identify areas where energy and money are being wasted.
If your current windows are double-pane and in good shape it is probably most cost effective to use retrofit measures such as caulking and weather stripping instead of replacing the windows.
