Different from the state of large-scale energy use and concentrated energy conservation in urban areas, the state of energy use and energy conservation in rural areas has its own characteristics and typical problems. Rural areas have been concentrated on the multiple differences in economic, social, and construction characteristics such as mountain and peace dam topography, natural and artificial construction, developed and underdeveloped, rapid urban development, and relatively backward rural development. It has practical problems that need to be solved urgently, such as the “insufficient savings” in the construction of farmhouses and the “insufficient open source” of clean energy applications. The discussion will be conducted from three aspects: the planning and layout design of rural houses in Chongqing, the performance of the enclosure structure of rural houses in key seasons, and the application of renewable clean energy in rural houses. Then put forward is the energy-saving design path of Chongqing farmhouse. It aims to improve the indoor and outdoor thermal environment of farmhouses, saving heating energy consumption in winter and air-conditioning energy consumption in summer and effectively benefit users to use renewable energy such as biogas, straw, and solar energy. Finally, explore the adaptability between the design methods of farmhouses and the local characteristics of Chongqing’s rural areas. In the work of Chongqing Design Going to the Countryside, we create a contemporary farmhouse case that is not only energy-saving but also has good indoor and outdoor space quality. It also provides a reference for the energy-saving design of farmhouses in Chongqing and other regions in China.

Energy Conservation Measures

Efficient energy use is critical for the success of any industrial facility since reduced energy consumption through energy conservation/saving programs can benefit not only consumers and utilities, but society in general as well. In particular, reduced energy consumption generally leads to reduced emissions of greenhouse gases and other air pollutants into the environment. It also helps reduce the operational costs in the facility. There is a strong need to take some energy saving measures in every plant/ facility. Although these may be quite diverse, some of these measures include thermal insulation, use of more efficient equipment, heat recovery systems, high efficiency lighting, changing the fuel, reducing the cost of compressed air, and enhancing productivity. In this study, some certain energy conservation measures are considered for assessing a packaging film manufacturing facility in Gaziantep, Turkey. Taking advantage of dry and hot climates of the city, cooling compressor inlet air by evaporative cooling technique is also assessed. Our investigation shows that there is a huge room for energy conservation measures. The total savings potential are expected to be 869,350 YTL (about $725,000) representing about 16% of the total energy consumption. The payback periods for the identified measures are justified. We believe that the results are typical rather than exceptional for the industrial sector in Turkey.

Air Conditioning System

Electricity is one of the most important resources for the growth and sustainability of the population. This paper assesses the energy consumption and user satisfaction of a simulated air conditioning system controlled with two different optimization algorithms. The algorithms are a genetic algorithm (GA), implemented from the state of the art, and a non-dominated sorting genetic algorithm II (NSGA II) proposed in this paper; these algorithms control an air conditioning system considering user preferences. It is worth noting that we made several modifications to the objective function’s definition to make it more robust. The energy-saving optimization is essential to reduce CO2 emissions and economic costs; on the other hand, it is desirable for the user to feel comfortable, yet it will entail a higher energy consumption. Thus, we integrate user preferences with energy-saving on a single weighted function and a Pareto bi-objective problem to increase user satisfaction and decrease electrical energy consumption. To assess the experimentation, we constructed a simulator by training a backpropagation neural network with real data from a laboratory’s air conditioning system. According to the results, we conclude that NSGA II provides better results than the state of the art (GA) regarding user preferences and energy-saving.

Taking a typical rural building as an example, the paper compares various factors that affect the heat load of the building, studies related literature and the living habits of rural residents, and suggests that the calculated temperature of the heating room in rural residential buildings in cold areas in winter is 14~17?C. Analyze and compare the initial investment and the investment pay-back period after the thermal insulation measures are adopted for each envelope structure. With the dual goals of energy conservation and economy, it is recommended that rural households with different economic conditions adopt different thermal insulation measures to provide clean heating in rural areas in the cold north. Provide strong technical guidance for energy conservation and emission reduction.

Energy cost is significant in many of the manufacturing activities. The efficiency of energy use is quiet low as there are substantial visible and hidden losses. Visible losses can be easily identified and corrective action can be taken. However hidden and indirect losses form a sizeable portion of the losses. Identifying these losses is not easy and requires an integrated approach which includes thorough study of process, operations and their interactions with energy use. Industries across sectors have implemented lean management principles which target various wastes occurring in the plant. This paper discusses case studies which highlight the exploitation of lean tools as a means for unearthing hidden energy saving potential that often go unnoticed. In addition to the energy savings which results in improved profits and competitiveness, the approach also aids the industry to pursue a path of sustainable manufacturing.

The Queen’s Residence Energy Challenge (QREC) is an energy conservation initiative taking place in the residence halls at Queen’s University coordinated by the AMS Sustainability Office and the Sustainability Coordinator for Student Affairs . It is a two-part competition. Part one of the competition is an interresidence competition in which each residence hall will be competing to reduce their energy expenditures. Energy use will be compared to the corresponding time in the previous year, and the residence that reduces their energy use by the highest percentage will win the competition. This part of the project is being organized by members of the AMS Sustainability Office and the Sustainability Coordinator (Office of Student Affairs), and Residence Life staff and floor dons are helping execute it. The second part of the competition is an inter-university pledge drive, in which residents will be encouraged to sign a pledge stating that they will be participating in the QREC. Queen’s will be competing against the Universities of Waterloo and Guelph, and the school that has the highest percentage of residents participating will win a set of solar panels as a symbol of energy conservation and renewable energy. This part of the project is being coordinated by the Sierra Youth Coalition who has obtained funding from the Ontario Power Authority. The goals of the QREC are to reduce overall energy use in the residences, help students living in residence learn about their own energy consumption and ways to reduce it, and create a culture of sustainability at Queen’s. In this presentation I will go through the overall timeline of executing and planning the project, provide examples of ways to reduce energy consumption in residence, and provide results of both parts of the competition.

subsistence production (where in the colonial period mainly extra-economic factors such as forced cultivation or forced labour caused the integration of the peasantry in the market exchange). Socialist development was there-fore strongly identified with modernising through the rapid expansion of the state sector, that is, nationalisation and mechanisation on an ever-increasing scale. The peasantry would be gradually absorbed within this expanding sector, and hence, at first, the role of the peasantry was seen as essentially passive with its transformation mainly centring on social aspects. As such, the policy of communal villages became virtually a habitational concept (and was in actual fact the responsibility of the national directorate of housing): a question of social infrastructures (water supplies, schools, etc.) within a concept of communal life without concerning production and its transformation. This view conflicted heavily with the objective conditions in the rural areas characterised by a deep involvement of the peasantry in market relationships and their dependence on it either as suppliers of labour power or as cash crop producers. This contradiction became more obvious, when the balance of payments became a real constraint (in 1979) and, hence, the question of financing accumulation cropped up more strongly in practice. The peasantry as suppliers of cash crops, of food and of labour power to the state sectors occupied a crucial position in production and accumulation. However, the crucial question then becomes whether the peasantry only performs the role of supplying part of the accumulation fund or whether the peasantry itself is part and parcel of the process of transformation and hence that accumulation embraces as an integral part the transformation of peasant agriculture into more socialised forms of production. In other words, it poses the question whether the strategy is based on a primitive socialist accumulation on the basis of the peasantry (transferring the agrarian surplus to the develop-ment of the state sector), or whether accumulation includes the transformation of peasant agriculture. Clearly, the way this question is posed in practice will influence heavily the nature of the organisation of the exchange between the state sector and the peasantry. The proposition that the state sector can develop under its own steam (with or without the aid of external borrowing) cannot bypass this crucial question since, on the one hand, a considerable part of foreign exchange earnings and of the food supply to the towns depended on peasant production and, on the other, the very conditions of productivity and profitability in the agrarian state sector depended heavily on the organic link that existed.between labour supply and family agriculture. The monetary disequilibrium originating from the state sector has a severe impact on the organisation of the exchange between the state sector and the peasantry. First, the imbalance between the demand for and the supply of consumer commodities affected rural areas differently from urban areas. The reason was that in urban areas the rationing system guaranteed to each family a minimum quantity of basic consumer necessities at official prices. In the rural areas the principal form of rationing remained the queue! Hence, forced savings were distributed differently over urban and rural areas. Furthermore, the concentration of resources on the state sector also implied that the peasants'

End Use

To achieve the goal of reducing greenhouses gases, many countries have recognized the importance of energy conservation in the building sector, and such countries are considerably strengthening their building energy conservation policies by reinforcing design standards, encouraging remodeling, and requiring zero-energy construction. In order to effectively strengthen these policies, it is necessary to provide information concerning energy consumption in the building sector to ensure the technical and economic feasibility of policies in the marketplace, and to allow building users and policy makers to easily access and understand energy consumption characteristics. It is important to provide information that allows people to effectively understand the state of energy consumption by end-use (space heating, space cooling, domestic hot water, etc.) as part of the creation of a concrete plan for energy reduction that incorporates various service systems and is familiar to people. This is because providing such information plays an important role in establishing concrete policies and encouraging voluntary energy performance improvements by building occupants. South Korea operates the Korea Energy Statistics Information System (KESIS) and the information provided by this type of information system consists mainly of energy consumption by energy source (electricity, gas, etc.), and such systems remain inadequate for providing effective information on energy consumption and energy use intensity (EUI) by end-use (space heating, space cooling, domestic hot water, etc.) as part of the creation of a concrete plan for energy conservation. In order to accurately provide energy consumption information by end-use rather than limit the information to mainly consumption corresponding to energy sources, in this study, measurement systems were installed in 2014 ~ 2016 based on the overall sampling designs of previous studies for apartment units, classifications, measurement and data gathering methods for energy consumption by end-use. The annual statistical values for EUI by end-use were collected from the measurement data for 71 sample apartment units from May 2017 to April 2018. This data was calculated and analyzed using stratification variable levels for completion year, supplied area, and the heat source type.

The Impact

The continuing importance of energy conservation in the building sector has drawn major attention to energy audits of existing buildings in different climates. In this paper, the energy conservation potential of a residential building located in Iran’s cold climate was investigated through an analysis of its actual energy consumption and through computer simulation. The building base-load was determined using a linear regression method based on existing energy bills, and was used to validate the computer simulation of its energy usage. The impact of typical energy saving solutions was evaluated for three cost refurbishment scenarios: low, medium and high. The results show that the existing construction and envelope materials fail to meet the national standards of Iran, but insulating the envelope was found to be a more cost-effective measure than modifying the windows. The results also demonstrate that although the use of energy-saving solutions has a significant impact on energy consumption, even the most economic solutions investigated will have a payback period longer than one decade. Thus, with current energy prices the reviewed energy conservation strategies are not economically justified in Iran from the consumer perspective, as investment in the methods considered typical in other parts of the world will not show a return for at least a half-century.

Abstract Objectives As a recently arrived vulnerable population, food insecurity might be associated with types of residence and nutrition knowledge among Syrian refugees residing in the State of Florida. We assessed the relationship between food insecurity status, types of residence and nutrition knowledge among Syrian refugees in Florida. Methods In one-on-one sessions, the assessments of nutrition knowledge and food insecurity were completed in 80 households (n = 80, 43 in rural area, 37 in urban area). The outcome measures included demographics, types of residence, food insecurity status, the levels of food insecurity, and nutrition knowledge. Results Of the 80 households, 20% were food secure while 80% of households experienced food insecurity at different levels. Fisher's exact test showed significant differences between the levels of food insecurity in rural and urban areas, P = 0.02. The mean nutrition knowledge score (42.0 ± 13.6) indicated that Syrian refugees had fair nutrition knowledge. Fisher's exact test showed marginal differences between the levels of food insecurity in households with different nutrition knowledge, P = 0.08. The results of our multivariate logistic regression model showed that types of residence had an inverse significant effect on food security, which remained significant after controlling for nutrition knowledge. Syrian refugees in rural areas had 78.4 greater odds of being food insecure compared with urban areas, odds ratio = 0.216, 95% CI: 0.06–0.777, P = 0.02. Conclusions Food insecurity was experienced by 80% of our participants. It was estimated that Syrian refugees had fair nutrition knowledge. Geographical location, types of residence, is a determinant for food insecurity status; Syrian refugees residing in rural areas are more likely to be food insecure compared with urban areas. Greater nutrition knowledge might increase the likelihood of food security among Syrian refugee households. Increasing sample size may be recommended to support our findings.
