In international references a net zero-energy building (NZEB) is defined as a residential or commercial building with greatly reduced energy needs through efficiency gains such that the balance of energy needs can be supplied with renewable technologies. According to this general term definition, the essence of the concept is that by using low-cost and locally available nonpolluting sources, they generate energy onsite, in a quantity equal or greater than the total amount of energy consumed onsite in the building. By using integrated design and building technologies, designer engineers are able to determine which energy efficiency strategies and what type of renewable onsite generation will contribute to higher energy performance to meet the requirements of the residential or commercial building considered. Therefore, it can be clearly established what kind of design and development strategies must be adopted in order to ensure an adequate energy balance, and as a result, comfortable and healthy home or workplace is possible to be created, with general characteristics that make NZEB buildings desirable and financially rewarding as well.
