A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1][2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and ...
If renewable energy from off-site is imported to meet the balance, it can be called net zero operational carbon. In new building developments, maximum embodied carbon reductions should seek to achieve, for example by choosing to renovate existing buildings or through building material selection.

Furthermore, visual representations like the one above help us fully grasp the concept of Net Zero Energy Buildings Definition.
The term net zero refers to the balance between the amount of produced greenhouse gas and the amount removed from the atmosphere. The term Net Zero Energy Building (NZEB) are characterized as zero net energy consumption buildings i.e. the total sum of energy used annually by the buildings is approximately equal to the total sum of the renewable energy produced on site. Recently, the idea of ...

A zero energy building, also known as a net-zero energy building, is a type of building that is designed and constructed to produce as much energy as it consumes on an annual basis. Could also be called Net-Neutral in some vernacular. Energy Efficiency through Design
