Net Zero Energy Building: An Energy Conservation Solution

The world energydemandsandCO2emissionsare and have been growing rapidly since ?n? number of years, it is estimated that they could increase by 65% and 70% respectively in the next 25years [1], with this in mind, the buildings sector is still responsible for around 40% of the energy use at a global scale, which contributes with about 36% of CO2 emissions [1]. For this reason, the NZEBs are crucial and are attained by applying energy conservation and efficiency measures and with the help of incorporating renewable energy systems. [2] Most applicable and widely used renewable energy supply at building scale are those utilizing non ? programmable renewable sources (NPRS), large scale NZEBs discussion into existing power grids, originally thought of and designed to deal only with unidirectional power flows, can impact the grids operation and stability. Globally the building sector accounts for more electricity use than any other sector, 42 per cent. With increasing urbanization, the number and size of buildings in urban areas will increase resulting in an increased demand for electricity and other forms of energy commonly used in buildings. [3] In the building sector there is a high degree of regulation for maintaining quality of the structure.
