Currently heating and cooling in buildings is responsible for over 30% of the primary energy consumption in the United Kingdom with a similar amount in China. We analyze heat pumps and district thermal energy network for efficient buildings. Their advantages are examined (i.e., flexibility in choosing heat sources, reduction of fuel consumption and increased environmental quality, enhanced community energy management, reduced costs for end users) together with their drawbacks, when they are intended as means for efficient building heating and cooling.

A literature review observed a range of operating conditions and challenges associated with the efficient operation of district heating and cooling networks, comparing primarily the UK’s and China’s experiences, but also acknowledging the areas of expertise of European, the United States, and Japan. It was noted that the efficiency of cooling networks is still in its infancy but heating networks could benefit from lower distribution temperatures to reduce thermal losses. Such temperatures are suitable for space heating methods provided by, for example, underfloor heating, enhanced area hydronic radiators, or fan-assisted hydronic radiators. However, to use existing higher temperature hydronic radiator systems (typically at a temperatures of >70°C) a modified heat pump was proposed, tested, and evaluated in an administrative building. The results appears to be very successful.

District heating is a proven energy-efficient mechanism for delivering space heating. They can also be adaptable for space cooling applications with either parallel heating and cooling circuits or in regions of well-defined seasons, on flow and return circuit with a defined change-over period from heating to cooling. Renewable energy sources can provide either heating or cooling through, for example, biomass boilers, photovoltaics, solar thermal, etc. However, for lower loss district heating systems, lower distribution temperatures are required. Advanced heat pumps can efficiently bridge the gap between lower temperature distribution systems and buildings with higher temperature hydronic heating systems

This chapter presents a case for district heating (and cooling). It demonstrates the benefits of reduced temperatures in district heating networks to reduce losses but also illustrates the need for temperature upgrading where building heating systems require higher temperatures. Thus, a novel heat pump was developed and successfully tested.

This chapter tests theoretically and empirically the existence of a stable relationship between energy consumption and CO2 emissions. Based on microeconomics and physics, a model has been specified and applied to annual data for twenty countries, which representing 61 percent of the world’s population in 2018, over the period 1995–2015. The data are from the International Energy Agency (2019) and econometric techniques including panel data and causality tests have been used. The results indicate that there is a causal relationship between energy consumption and CO2 emissions. In general, consumers cannot directly change emissions caused by production processes, but they can act on emissions caused by their own domestic energy consumption. Approximately three quarters of domestic energy consumption is due to heating and domestic hot water consumption. Taking into account the lower emissions and the lower economic cost of the initial investment, four potential energy systems have been selected for use in heating and domestic hot water. Their social returns have been assessed across nine of the twenty countries in the sample over a lifecycle of 25 years from 2018: France, Portugal, Ireland, Spain, Iceland, Germany, United Kingdom, Morocco and the United States. Cost-benefit analysis techniques have been used for this purpose and the results indicate that the use of thermal water, where applicable, is the most socially profitable system among the proposed systems, followed by natural gas. The least socially profitable systems are those using electricity.

Workarounds represent informal modifications to rules and procedures that individuals will engage into navigate around a process block in order to make their job easier. Although workarounds have been primarily studied from an individual-level perspective, this chapter argues that workarounds are a socially constructed, multilevel phenomenon, meaning that they are influenced by others (e.g., group norms and coworkers) and can result in the emergence of workaround climates. We find empirical support for the view that workarounds are shaped by a variety of social influences. Moreover, based on an inductive exploratory study, we suggest that workarounds are related to informal training and troubleshooting behaviors. We conclude by outlining several theory-based directions for understanding how workarounds spread throughout all levels of an organization as an incubator for future research.

This chapter presents the Smart Irrigation system using the Internet of Things (IoT). IoT Technology is a network of physical objects that are connected with sensors, software, etc. This chapter concludes the project based on the agriculture field that automates the irrigation process and on the agriculture field that automates the irrigation process and solves the challenge of water consumption in those areas. We have developed the system using different sensors like (1) Soil Moisture sensor, which measures the moisture present in the soil, (2) Humidity and Temperature Sensor (DHT11), which traces the temperature change. All these sensors are connected to the Node MCU ESP8266 microcontroller, which is also a Wi-Fi module. It uploads the data to the cloud and displays it in the form of readings detected by the Blynk Application. This sensor's reading values control the pump for emergency purposes, such as stopping the pump for irrigation. Thus, this project can automate the irrigation process by analyzing soil moisture and climatic conditions, covering essential aspects like less labor, power consumption, reliability, and cost.

This chapter investigates how we have come to know what we know, in the United States, about the terms “ability” and “disability” through the story of Helen Keller and her teacher Anne Sullivan Macy. What is the narrative of Helen Keller as told through children’s literature? How might the ways in which her life is presented contribute to stereotypes of what it means to be disabled? What, if any, are the ways in which authors of these books resist writing about her as someone who “overcame” her disabilities? How is Helen Keller’s relationship with her teacher, Anne Sullivan, portrayed and what might this representation contribute to the concepts of dependence and interdependence?

This project provides a sociological analysis of common themes through a content analysis of 20 children’s books on Helen Keller.

The theme of the widely circulating “story of the water pump moment” (when Keller realizes that hand movements signify language) depicts a one-sided relationship of Helen Keller and her teacher Anne Sullivan Macy. This informs the narrative representations of Anne Sullivan Macy as “miracle worker” and Helen Keller as “miracle child.” Another theme is the “complexities of resistance,” which shows how these narratives uphold the stereotype that Helen Keller needed to “overcome” her disabilities while also resisting this notion and showing how she also helped Anne Sullivan Macy.

This demonstrates how widely circulating stories such as those about Helen Keller shape what we know about what it means to be abled or disabled, challenges simplistic binary understandings of the disability experience, and points to the power of narratives to shape systems of beliefs.

To illuminate the underlying logic of western Kansas farmers’ decisions to irrigate at unsustainable rates and the state’s regulatory policies and practices that enable depletion of the Ogallala aquifer.

Ethnographic interviewing of 39 western Kansas farmers, state water management personnel, and archival research.

Farmers occupy an ambiguous position as petty capitalists who focus attention on their own farms with seasonal planning horizons, and they hold a view of “good stewardship” that melds economic and noneconomic considerations, and that provides a rationale for unsustainable irrigation practices. The state resolves the contradiction between the finite groundwater resource and ideological commitments to economic growth by devolving responsibility for water management to groundwater users.

While the small sample size is likely to be representative of the larger pool of irrigators, further research with other farmers representative of the region will be necessary to verify findings.

Depletion of the Ogallala aquifer contributes to farm consolidation and community decline, and the ecological costs will leave future farmers and remaining communities without the benefits of groundwater. Western Kansas will likely have to revert to a system of dryland farming.

The use of fossil fuels in developing countries places increasing economic, health, and environmental costs on the population. In decentralized and rural communities without existing grid systems, direct solar technologies provide the basis for electricity production, for water pumping and hot water, and for heating of houses. Examples and case studies for each of these direct solar technologies are presented which may be directly applicable or potentially modified for rural development in countries such as Uzbekistan and Turkmenistan, which have ample direct solar resources. Related design involving both daylighting and passive cooling are described as part of the incorporation of passive solar heating techniques.

This chapter will introduce three novel technologies demonstrated in Sino-Italian Green Energy Lab of Shanghai Jiao Tong University for the hot summer and cold winter climate zone.

Experimental and modeling works have been conducted on the application of these systems. A comprehensive review on the features of these novel technologies, their adaptability to local climate condition have been carried out, and some initial study results have been reported.

Solar PV direct-driven air conditioner with grid connection, home used small temperature difference heat pump, smart house energy information and control system are appropriate energy technologies with reduced CO₂ emission, which can be applied efficiently in the hot summer and cold winter climate zone. More useful data will be obtained in the future demonstration tests in Sino-Italian Green Energy Lab.

This work shows combining renewable energy technologies and information technologies is crucial to improve the energy efficiency and the comfortableness for indoor environment.

Three themes dominate Hunting Causes. The first is that cause is a plural concept. The methods and metaphysics of causation, Cartwright believes, are context dependent. Different causal accounts seem to be at odds with one another only because the same word means different things in different contexts. Every formal approach to causality uses a conceptual framework that is “thinner” than causal reality. She lists a bewildering variety of approaches to causation: probabilistic and Bayes-net accounts (of, for example, Patrick Suppes, Clive Granger, Wolfgang Spohn, Judea Pearl, and Clark Glymour), modularity accounts (Pearl, James Woodward, and Stephen LeRoy), invariance accounts (Woodward, David Hendry, and Kevin Hoover), natural experiments (Herbert Simon, James Hamilton, and Cartwright), causal process accounts (Wesley Salmon and Philip Dowe), efficacy accounts (Hoover), counterfactual accounts (David Lewis, Hendry, Paul Holland, and Donald Rubin), manipulationist accounts (Peter Menzies and Huw Price), and others. The lists of advocates of various accounts overlap. Nevertheless, she sometimes treats these accounts as if they were so different that it is not clear why they should be the subject of a single book. And she fails to explain what they have in common. If, as she apparently believes, they do not have a common essence, do they have a Wittgensteinian family resemblance? She fails to explore in any systematic way the complementarities among the different approaches – for example, between invariance accounts, Bayes-nets, and natural experiments – that frequently make their advocates allies rather than opponents.
