Abstract: Indoor environment of VAV system was paid more increasing attention, besides the energy saving, zone temperature control of VAV system. In this paper, using in-site testing and analysis, some experiments were conducted on indoor environment of the typical office with self-regulating inlet VAV system. The results showed the temperature and relative humidity of the selected office were in the range of 22.8 °C~24.5°C and 27.0%~35.0%, respectively. The maximum volume of total supply airflow is 816 m³/h, while the minimum one is 557 m³/h. The concentration of carbon dioxide ranged from 0.0596% to 0.0873% (v/v). The calculated maximum value of temperature uniformity coefficient was 0.026 that indicated the distribution of indoor air is uniformity. So this VAV system used in the office building provided a good indoor environment to meet the satisfaction of the office staff.

Abstract: In this paper, a series of scientifically rational index system is set up to evaluate the effect of energy saving and loss decreasing in power distribution networks. The establishment of the index system is based on a variety of new technical measures. According to the feature of wide range and weak consistency, an evaluation in power distribution networks based on rank correlation analysis is proposed. In such a way, the procedure is clear, simple and highly exercisable. With the application of evaluation process described in this paper, present situation in power distribution networks in a region is evaluated, which justifies the validity of the method.

Abstract: CO₂/water displacement process in porous media under conditions of CO₂ geological storage was observed by using X-ray CT. The porous media was a packed bed filled with glass beads. The size of the glass beads in the packed bed is 0.2mm in diameter and the flow rates were adjusted by the fractional CO₂ flow rates from 1.2 to 3.6 ml/min. The porosity and CO₂ saturation were measured during the packed bed flooding experiments under conditions of two-phase of CO₂ and brine (P ~ 8.0 MPa and T = 40°C). The observation results show that the CO₂ displacement efficiency is strongly affected by the heterogeneity of the packed bed. However, it is the buoyancy that plays a key role on governing the CO₂ saturation distribution, which was observed from the experiments under variant of fractional flow rates. The results obtained from this study, especially the CO₂ saturation distribution, provided informations on further investigating the mechanism of the movement and immobilization of CO₂ plumes for CO₂ geological storage.

Abstract: China is launching a pilot carbon trading, but carbon trading must be based on the reasonable allocation of carbon emission rights. Current research mainly focused on the regional allocation of carbon emission rights(distributing total carbon emission rights to each area),but industry allocation research is need deeply study. Power industry is one of key industries of carbon emissions,so research about distributing power industry carbon emission rights to each power enterprise is very important. Based on principles of fairness, efficiency, feasibility and sustainability, a multiple attribute decision making model is constructed to slove the problem of power industry allocation. Finally, through comparing and analyzing the allocation results of different methods , find that the constructed model can balance the difference of each power enterprise better, and has stronger operability.

Abstract: Wheat washing can remove stone, dampen and clean. It works by the water solubility and flushing action to purify surface of wheat. For water consumption and pollution of traditional wheat washing machines have become increasingly prominent, the water-saving cleaning technology based on grading washing was studied. In this paper, principle on grading washing is first shown. In order to make full use of grading washing effect, a realization solution based on grading washing technology is designed. For verifying the effect on grading washing, comparative experiments were done. After wheat is sent into washing machines, primary-washing, secondary-washing and final-washing are completed. Compared with traditional wheat wet washing technology, the measurement value about cleaning effect is not reduced. With the water-cycling system, effective reuse for water is achieved. water-saving is about 2/3. The pollution to environment is reduced fundamentally, and the production cost of enterprises is significantly reduced.

Abstract: The human development would not be possible without energy. But the way electricity has been generated and fuels have been burnt causes serious impacts in environment. Our current society is concerned about these problems, and studies have been carried out to find renewable power sources and ways to use energy as efficient as possible. In this context, we will study the electrical generator park of Rio de Janeiro State, which is composed by hydroelectric plants, one wind farm, thermal plants and two conventional thermonuclear plants, having reached an installed capacity of 7.991 MW in 2012. In this same year, the electric generation in the state was 51.633 GWh, which accounted for 9,3% of national production, while the electricity consumption of 50.746 GWh represented 10,2% of the country's consumption. An increase in electricity consumption is expected for the next years due to the heating of the state economy, the large industrial investments and the great international events which will take place there. Therefore, the state will have to expand the capacity of its electric generating facilities, preferably in a sustainable and efficient way. This project aims to study how energy is used and generated in Rio de Janeiro State and begin to compile its energy inventory, so that, further studies can be conducted in order to make a comparative of these energy sources through the life cycle energy analysis seeking viable alternatives to the electricity demand in the state.

It also proposed the control strategy, which combined low-carbon development of industrial park with green infrastructure, to boost a sustainable development of low-carbon green industrial park.

Abstract: For discussing the shape, turning point and influencing factors of Environmental Kuznets Curve (EKC) for Chinese CO₂ emissions, by using data for 1960-2009, the dynamic relationship between income, other affecting factors and CO₂ emissions was studied utilizing the Auto Regressive Distributed Lag - Error Correction Model (ARDL-ECM) and boundary test methodology. The results suggest the existence of cointegration relationship among variables and presence of an inverted-U shape relationship in both short and long-run, thus supporting the EKC hypothesis. At present China has not surpassed the curve’s turning point. Energy intensity is key influencing factor for CO₂ emissions. Industry structure is positively correlated with CO₂ emissions. However, trade openness has little influence on it. The short-run environmental negative effect of urbanization and long-run positive effect of population density are both significant, the regression coefficient of energy consumption structure is positive in long-run but negative in short-run.

Abstract: Recent years the hospitality in China has undergone a rapid growth, yet "high input, high consumption, high pollution" characteristics of hospitality have become a burden for future development. The prerequisite for energy saving and emission reduction in hospitality is to establish an effective energy consumption assessment system, which is suitable for the hospitality industry. Though the analysis of the data collected from the hotels in the eastern China, the paper establishes the frame of Monitoring Reporting Verification (MRV) and a multi-dimension comprehensive energy consumption assessment system. Then, the paper assesses the energy consumption of various hotels by using the Monitoring Reporting Verification (MRV) and draws a few conclusions, which provide firm foundations for carbon trading in hospitality and benefit energy saving and emission reduction.
