Realization of a zero energy housing validation complex through the use of renewable energy systems

The Zero Energy Housing Research aims to achieve ‘net zero source energy’, which means zero fossil energy for the building energy that is the 5th energy adopted by most countries around the world.

The Korea’s first zero energy validation complex, which is constructed at Hagye-dong, Nowon-gu, Seoul and will house 121 households, will realize ‘net zero site energy’, meaning that the consumption amount of the building energy, which is the 5th energy in households, equals the amount of energy produced from geothermal and solar sources. In addition, the complex is a site of net zero source energy because the amount of the renewable energy is greater than the fossil energy produced by the government.

‘Net zero energy cost’ is currently dependent on the renewable energy purchase policies of energy suppliers. It is difficult to predict the domestic selling and purchasing costs due to various variables and the cost difference may vary depending on the methods of settlement, which is why the net zero energy cost should be settled separately based on the period and amount of use.

When it comes to ‘net zero energy emission’, it is required to validate the amount of used energy and the amount of emitted carbon dioxide at individual stages, according to the life cycle of a building, including the stage up to the completion of a building, during the operation of the building and the stage of wasting the building, or it is also required to review the amount of carbon dioxide generated and reduced during the operation of the building. Considering this, all the answers to the results can be calculated at the final stage at which the entire design is completed and there will be no more design change during construction.
