XeroHome uses advanced building energy simulation tools to estimate how much energy a home will use with various combinations of energy upgrades. It then recommends the combination that works best to achieve Net-Zero Energy. However, in some homes, it may not be possible to achieve Net-Zero Energy. In those cases, XeroHome will recommend energy upgrades that get the home closest to the Net-Zero Energy goal. XeroHome’s energy modeling calculations are also based on best available data about a home from public records, and any input received from the homeowner. The calculations are hence only as accurate as the data available. 

For these reasons, no guarantees, either expressed or implied are made about a home achieving Net-Zero Energy status with the recommended energy upgrade plan. Please refer to our terms of use for further details.
