TOWARD FUTURE: POSITIVE NET-ENERGY BUILDINGS

Abstract

For a positive net building (PNEB), the paper presents its need, and tools to achieve its design. The PNEB should provide the maximum thermal comfort with a minimum of energy, primary energy, and exergy consumption, .and reduction of the use of energy resources, maximizing energy security, as well as the minimum impact on the environment. This very useful knowledge is also needed for identifying energy efficiency, as well as for dictating the right energy management strategies of a country. Then, the paper presents the software for a energy simulation and optimization of PNEB. After that, the paper describes the three examples connected to the PNEB. The first example is a simulation of a residential PNEB in Serbian conditions, second the optimization of photovoltaics panels area at Serbian zero-net energy building, third the description of an the building and optimizing energy performances, by placing the solar collector in the optimum position.
