Zero Energy Home

A zero energy building (ZEB) is a term used to a building with an overall
energy usage of zero over a year. This is measured in relation to cost, energy, and CO2 emissions.

Zero Emissions, Big Savings

Energy Efficent home technologies remain unknown in developed countries but are gaining in importance and popularity. This is seen as a big step forward in finding solutions to ever bigger environmental issues and our addiction and dependence on fossil fuels. A home is deemed to have a zero energy rating when it produces a surplus of energy without inefficiency. With the U.S and the rest of the world using the term “zero energy home” both have different definitions.




Zero Cost

At the basic level ‘net zero energy’ is the price of energy. The cost of buying the energy is balanced by income from sales of electricity to the grid of electricity generated on-site. At this time it is unknown if it can be maintained over the next 10-20 years and is subject to fluctuations in energy prices.

The amount of energy used in a zero-energy home by a renewable energy sources cancel out the
amount of energy used by the Building and has significant Home Energy Savings

Net zero energy use

If a zero energy home buys energy from a renewable energy source that is based in a different location a zero energy home will still hold its rating as such. In the E.U a net zero energy building is defined as one with zero net energy emissions, or non- producing of CO2 emissions. Zero carbon building or zero emissions building is another definition .This means that fossil fuel emissions are off-set by the amount of renewable energy production.


The cost of fossil fuels will increase dramatically in the future as depletion becomes more apparent, so learning how to save energy in homes will become a necessity as we learn to use alternative forms of energy.
