Zero Energy Buildings

The article analyzes energy supply alternatives for modernised public nearly zero energy buildings. The paper examines alternative energy production systems such as heat pumps (air-water and ground-water), solar collectors, adsorption cooling, biomass boiler, solar photovoltaic, wind turbines and combinations of these systems. The simulation of the analysed building energy demand for different energy production alternatives has been performed using TRNSYS modelling software. In order to determine an optimal energy supply variant, the estimated results of energy, environmental, and economic evaluation have been converted into non-dimensional variables (3E) using multi-criteria analysis.

Zero Energy Buildings

The paper is oriented on the design of energy concepts of zero energy buildings. In the first phase of concept is important the good architectural design in terms of energy. In the residential building for four flats I calculated the annual energy consumption by computer simulation in the current condition and in the proposed reconstruction. I demonstrate that the unbalanced architectural design of flats in a residential building causes also after reconstruction a significant difference in energy consumption. This means that when developing energy concept of zero energy building the first essential step is energy efficient architectural design, taking into an account the energy aspects. The next step is to the use of technological aspects: passive and active use of solar gains, effective ventilation systems with heat recovery and new generation of heat pumps. For the formation of zero energy buildings is essential application of described progressive trends in the development of energy concepts.

Zero Energy Buildings

In the current century, a suitable strategy is concerned for optimal consumption of energy, due to limited natural resources and fossil fuels for moving towards sustainable development and environmental protection. Given the rising cost of energy, environmental pollution and the end of fossil fuels, zero-energy buildings became a popular option in today's world. The purpose of this study is to investigate the factors affecting the design of zero-energy buildings, in order to reduce energy consumption and increase productivity, including plan form, climatic characteristics, materials, coverage etc. The present study collects the features of zero-energy building in Isfahan, which is based on the Emberger Climate View in the arid climate, by examining the books and related writings, field observations and using a descriptive method, in the form of qualitative studies. The results of the research showed that some actions are needed to save energy and, in general, less consumption of renewable energy by considering the climate and the use of natural conditions.
