Toward Future: Positive-Net Energy Building

Abstract

For positive net energy building (PNEB), the paper presents need, definition and its elements. The most important is that PNEB should provide the maximum thermal comfort with minimum of energy, primary energy, and exergy consumption, and minimum of CO2 emission throughout its life. Then, the paper presents the software for energy simulation and optimization of PNEB. After that, the paper describes the five examples connected to PNEB. The first example is a simulation of a residential PNEB, second the optimization of photovoltaics in a residential PNEB, third the description of an the building as power plant initiative, fourth the description of an office PNEB, fifth description of an archive PNEB and finally a description of a headquarter PNEB.
