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.

Four major crops rice, maize, wheat and tomato were examined in the Kano River Irrigation Project. The project was divided into 3 sections; the head, middle and tail ends. One hundred farmers were randomly selected from each sections making a total of 300 hundred farmers. Net farm income, and profitability index were used to assess the profitability of the enterprises. It was concluded Rice, maize, and wheat were profitable while tomato was unprofitable that year attributable to market glut and perishability of the crop. It was recommended that storage facilities be provided by both private and government agencies to curtail the losses incurred by the farmers.

This paper presents a comparative study of two experimental systems, stabilization ponds without macrophytes and macrophytic ponds, to purify wastewater under arid climate of Marrakesh. Organic load (COD, TSS), bacterial load (SF, CF) and parasitical load (helminth eggs) are significantly reduced in both systems. Even though water loss was more important at the macrophytic ponds (evapotranspiration reaches 60% of influent flow), this system shows generally the best efficiency in purifying wastewater. In summer time, TSS and COD depletion is better on macrophytic ponds (TSS: 95%, COD: 87%). The stabilization ponds are more efficient to reduce nutrients: NH4+: 72%. PO4: 63% at the same period. Fecal streptococci and fecal coliforms are reduced more in stabilization ponds (CF: 99.4%, SF: 99.7%) than macrophytic ponds (CF: 96.2%, SF: 94.7%). No helminth eggs were found in the effluent from either system. The two systems ensure optimal removal of parasites allowing the eventual reuse of the treated effluents for agricultural purposes.

Conventional olfactometric techniques have been used to evaluate odours from sewage treatment and sludge storage facilities primarily in terms of odour concentration relative to their detection thresholds. However, such data conveys limited information that would be useful for determining the causes of most odours or the most appropriate remediation measures to be taken. Thispaper discusses some recent work undertaken to characterise the olfactometric profiles of different odours. Standard descriptive terms were used to characterise odours at normalised, moderately strong concentrations. These were used directly for the calculation of hedonic tone. They were also collated into a small number of generic odour groups and plotted to allow visual comparisons of different odour profile fingerprints. Such odour characterisations have proved to be very useful and may easily be incorporated into normal olfactometric evaluations.
