Authors: Zhang Zhi Jun
Published: July 2014

A zero-energy building, also known as a zero net energy (ZNE) building, net-zero energy building (NZEB), or net zero building, is a building with zero net energy consumption and zero carbon emissions annually. Buildings that produce a surplus of energy over the year may be called “energy-plus buildings” and buildings that consume slightly more energy than they produce are called “near-zero energy buildings” or “ultra-low energy houses”. Traditional buildings consume 40% of the total fossil fuel energy in the US and European Union and are significant contributors of greenhouse gases. The zero net energy consumption principle is viewed as a means to reduce carbon emissions and reduce dependence on fossil fuels and although zero energy buildings remain uncommon even in developed countries, they are gaining importance and popularity.

Solving Discrete Dirichlet Problems on Spectral Finite Elements by Fast Domain Decomposition Algorithm
Authors: Korneev V.G.
Published: July 2014

A key component of DD (domain decomposition) solvers for $hp$ discretizations of elliptic equations is the solver for the internal stiffness matrices of $p$-elements. We consider the algorithm of the linear complexity for solving such problems on spectral $p$-elements, which, therefore, in the leading DD solver plays the role of the second stage DD solver. It is based on the first order finite element preconditioning of the Orszag type for the reference element stiffness matrices. Earlier, for spectral elements, only fast solvers obtained with the use of special preconditioners in factored form were known. The most intricate part of the algorithm is the inter-subdomain Schur complement preconditioning by inexact iterative solver employing two preconditioners -- preconditioner-solver and preconditioner-multiplicator. From general point of view, the solver developed in the paper, is the DD solver for the discretization on a strongly variable in size and shape deteriorating mesh with the number of subdomains growing with the growth of the number of degrees of freedom.

Authors: Zeng Lin , Shi Tie Mao , Hu Yuan Man
Published: July 2014

As the residential area is the basic functional unit in the city, its number is large and its construction project is huge; accordingly, the CO2 emission is also huge in the process of construction and use. On the basis of the LCP theory and method, the researchers in this paper propose a new approach used to calculate the carbon emissions in the urban residential area through comprehensively considering the CO2 emission and CO2 absorption of carbon sink-green space in the total life cycle of the urban community. In addition, taking the typical multi-story residential areas in Shenyang City as the sample, the researchers calculate the carbon emission and discuss the features of emission in the residential area as well as the method and potential of reducing the carbon emission. The calculation results show that, the carbon emissions in the process of operation an use account for the largest proportion for the total life cycle, up to 83.8%; the carbon emissions in the process of preparing the materials for construction account for 7.69%; the carbon emissions at the stage of building demolition account for 5.32%. The carbon emissions at the stage of construction are the smallest in amount, which can be basically negligible. According to the existing energy structure, construction specifications and technical level, 4.8% of the CO2 emissions in the residential area can be absorbed through the green space and that the carbon emissions in the residential area can be reduced through taking the energy conservation measures, using the renewable energy and increasing the area of carbon sinks.

Condition of Road Infrastructure Related with Regional Development
Authors: Bashkarev Andrey A. , Rajczyk Jarosław
Published: July 2014

Russia, as many other large countries, is a historically multinational state. In the conditions of administrative and territorial dissociation the social infrastructure of the remote regions, where transport systems are poorly developed, degrades. It is common especially for the northern regions with their severe climate. For example, various subjects of the Russian Federation are inhabited by over 180 national populations, one third of whom can be considered small ethnic groups. Total, they account for 500 thousand, or 0.3% of the whole Russian population. The fact that the 20th century industrialization almost didn't affect these remote ethnic regions was caused by poor road infrastructure. On the one hand, this contributed to the preservation of these ethnic group identity, but on the other hand, this led to the problems in realizing state social programs for such small ethnic groups. For the latest 50 years a number of small ethnic group population has significantly reduced. This is not caused only by the natural assimilation, but also by the ineffective implementation of the projects aimed at the development of road networks. The present article considers this problem referring to the situation with Finno-Ugric ethnic group Vespians in modern Russia. The article provides the proposal about complex development of social and transport infrastructure aimed at the preservation of this small ethnic group in the globalization conditions.

It was shown that almost all AOX were present in highly disperse state (less than 60 nm), 55...90% of iron and 55...80% of aluminium belonged to impurities with size over 60 nm. Changes of contaminants state and concentration were explained by influence of water treatment processes and corrosion of steel water distribution pipes.

The degradation of chlorpyrifos is investigated with the treatments of sonolysis, ozonolysis, and sonolytic ozonolysis at various frequencies. Results show that there exists frequency effect in sonolytic ozonolysis. In sonolytic ozonolysis, the maximum degradation rate is obtained at 495 kHz, and the degradation kinetics is fitted to the first-order kinetics model well. However, the most significant synergistic effect between ultrasonic and ozone is at 124 kHz. The kinetics parameters indicate that chlorpyrifos is much more labile to ultrasonic at 495 kHz, while ozone is much more soluble at 124 kHz. The hydrolysis and oxidation are deduced to contribute to the degradation reaction and the degradation pathway for chlorpyrifos degradation is proposed.

To compare the removal efficiency of 2-MIB by traditional water treatment, prechlorination, O3-BAC, MIEX pre adsorption and UV/H2O2 advanced oxidation process, the pilot-test of drinking water odor control technology were studied in this paper. The results showed that the traditional water treatment process had poor effect on removing 2-MIB, with about 10% removal rate, while the O3-BAC process was the best at removing 2-MIB, whose removal rate reached over 90%. And the 2-MIB removal rate of UV/H2O2 process was about 55% and that of prechlorination process was about 20%. However, the MIEX pretreatment process had almost no effect on removing 2-MIB.

This paper reports a design proposal of a sonochemical setup for pesticide wastewater degradation. Multi-parameters obtained by multi-sensors of the setup were utilized to control experimental variables and analyze degradation effect. Based on the setup and method designed, degradation experiments of deltamethrin were set up. In the work, treatments using ultrasonic, ozone, and the combination of them were carried out respectively, and parameters including ultrasonic frequency, pH, electrical conductivity, temperature as well as mass were taken into consideration. Results indicated that deltamethrin could be degraded efficiently under the irradiation of 589 kHz US/O3 combined and the degradation rate could reach 91%.

Secondary water supply equipment was designed based on the current water supply source and municipal pipe network. The combination between Water purification and pressure-superposed water supply could guarantee the drinking water security, fully exploit the municipal pipe network pressure, and effectively save the energy. Catalytic oxidation of ozone, complex adsorption, and microbial degradation collaborated to treat the micro-polluted water. Activated alumina was employed for the high fluoride water purification with HCl/NaOH deep regeneration. For the brackish water, membrane treatment was adopted. A collaborative technology of ozone oxidation, contact oxidation, and biological oxidation was used for the iron/manganese-rich water. The results showed that all the effluents could meet the requirement of "Sanitary standard for drinking water" (GB5749-2006) and "Water quality standards for fine drinking water" (CJ94-2005).
