Abstract
A net-zero energy building (NZEB) is a residential or commercial building with greatly reduced energy needs. In such a building, efficiency gains have been made such that the balance of energy needs can be supplied with renewable energy technologies. Past work has developed a common NZEB definition system, consisting of four well-documented definitions, to improve the understanding of whatnet-zero energy means. For this paper, we created a classification system for NZEBs based on the renewable sources a building uses.
