More than 30 international research and pilot seasonal thermal energy stores (TESs) were realized within the past 30 years. Experiences with operation of these systems show that TES are technically feasible and work well. Seasonal storage of solar thermal energy or of waste heat from heat and power cogeneration plants can significantly contribute to substitute fossil fuels in future energy systems. However, performance with respect to thermal losses and lifetime has to be enhanced, while construction costs have to be further reduced. This paper gives an overview about the state-of-the-art of seasonal thermal energy storage with the focus on tank and pit TES construction. Aspects of TES modeling are given. Based on modeled and measured data, the influence of construction type, system configuration, and boundary conditions on thermal losses of large-scale TES is identified. The focus is on large-scale applications with tank and pit thermal energy stores and on recent investigations on suitable materials and constructions. Furthermore, experiences with the operation of these systems with respect to storage performance are discussed.

No physical optimum solar chimney power plant exists when only regarding the dimensions of such a plant. However, if construction costs are introduced, thermoeconomically optimal plant configurations may be established. This paper investigates the thermoeconomic optimization of a large-scale solar chimney power plant. Initially, relevant dimensions are selected, which are to be optimized. An approximated cost model is then developed, giving the capacity for finding optimum plant dimensions for different cost structures. Multiple computer simulations are performed and results are compared to the approximated cost of each specific plant. Thermoeconomically optimal plant configurations are obtained.

AbstractIn this chapter we discuss China’s evolving policies toward Chinese nationals abroad, with particular attention to the expanding area of social protection. Our analysis shows that China’s policy-making activities concerning diaspora have been largely driven by a focus on economic agenda rather than social welfare. This chapter presents a detailed picture of China’s social protection provision towards its diaspora and shows how its policy-making is guided by priorities which vary from one field to another. We trace how “overseas Chinese affairs work” has developed through expanding policy infrastructure, encouraging China’s diaspora to participate in national economy and trade, science and technology developments, and large-scale crisis response, yet has seen limited developments in the area of day-to-day social protection of Chinese nationals abroad.

<p><b>Designers are encountering greater issues with residential projects, which are increasing in complexity, scale, and performance requirements. Despite significant advancements in technology and the AEC industry, large-scale residential developments are still designed and built at scale as if they were singular projects. Variable and increased construction time, cost, and material waste at scale are all issues with existing design and construction methodologies for construction at scale. Prefabrication and generative design tools have the potential to significantly reduce these issues.</b></p> <p>This paper investigates how collaborative, human-generative design tools can optimise building performance and make prefabricated housing at scale feasible, whilst still encouraging design variance. In this context, collaborative human-generative tools refer to a partially algorithmic design tool that facilitates an open-box approach to design. Using a mixture of research-based design and design-based research, a new tool (PARAMTR) was created to improve feasibility whilst reducing time, complexity, and cost of designing and building residential projects using prefabrication at scale. </p> <p>The research demonstrates eight unique designs produced using the new human-generative tool. Despite their individuality, these designs have 8-10 times fewer unique components when compared to existing residential projects. Designs produced using PARAMTR could reduce construction/design time by up to 50%, reduce construction costs by up to 26% and share no design commonality, enabling unique designs across an entire development. This research paper could therefore fundamentally change how the AEC industry builds at scale, using algorithms and human-generative design tools.</p>

This paper examines whether Amartya Sen’s entitlements and capabilities concepts can be transferred in their application from low-income countries to high-income countries, specifically Cumbria, Northern England. Originally used to understand the causes of famine, these concepts have previously been used in several different geographical contexts to broadly understand poverty and inequality but almost entirely in low-income countries. This paper applies these concepts to a United Kingdom context in an attempt to understand the causes of poverty and inequality among people experiencing “livelihood crisis.” The research uses data from two nongovernmental social welfare projects to examine the causes of crisis and the remedial effects of the intervention. Our findings indicate that these concepts can help to explain how people find themselves in crisis in Cumbria. On a broader level, they can also be used to explain poverty, inequality, and disadvantage in communities in the United Kingdom. The authors put forward that entitlements and capabilities provide a useful framework to advance the policy and political debate on the causes of poverty by providing a straightforward language and broad application. Entitlement and capabilities can also assist social welfare programs in framing their aims and objectives and through improved understanding about the causes of inequality, will be better able to support people out of disadvantage by strengthening entitlements and building capabilities, without the necessity of large-scale investment.

This chapter outlines the developments against which one can understand the emergence of Soviet city-building—painting a picture of successive formations of government from Petrine absolutism to Soviet total planning. In the Soviet period, the city emerges precisely as that space in which large-scale readjustments of the population's distribution and way of life can be governmentally managed. The chapter then traces the articulation and subsequent redeployment of two critical instruments of government—budgets and infrastructures. Initially developed in the state-building and modernizing projects of the Russian absolutist state, these instruments were turned—first in the late tsarist period, then in the Soviet period—to various subsequent tasks of development and social welfare, and embedded in the mechanisms of Soviet planning. Their present significance lies, in part, in the fact that they were identified as critical targets of neoliberal reform after Soviet breakup, and will thus be crucial for assessing the postsocialist fate of Soviet social modernity.

New recast of the EPBD requires that that Member States shall establish a long-term strategy facilitating the cost-effective transformation of existing buildings into nearly-zero energy buildings. Lack of fund and lack of awareness is often considered to be the main barrier for the renovation. Experiences with renovation grant scheme in Estonia showed that large scale renovation scheme is a challenge to the construction industry and increased demand creates new problems like labour shortage and increased construction costs. Current renovation rate of apartment buildings in Estonia is approximately 200 buildings (~1%) per year. Demand is higher but current renovation technologies makes it difficult to significantly increase the renovation rate. Achieving the deep renovation goals with current technologies would require expansion of the whole construction sector (designers, contactors, material industry), which is difficult to achieve. Therefore, innovation and new technologies are needed. The prefabrication would be one solution to allow automation of the renovation process and renovate the existing housing stock within a reasonable time period.

During the past generation, social welfare has risen to a position of almost prime importance in the work of government. “Social services” have rivalled “defense services” as objects of public expenditure. “Social security” has complemented “national security” as an objective of public policy. Graduate schools of social work have taken their place alongside law schools, schools of education, and military and naval academies as important training-places for public service. It is perhaps time that we now inquire in what ways political science has been, or may yet be, affected by so phenomenal a change. If, as we are often assured, atomic fission means a revolution in our political thinking, the large-scale pursuit of social welfare might at least be expected to call for an equally vast, even though more gradual, evolution in our attitudes.As an organized body of professed political scientists, how have we reacted to this change? We have, by and large, welcomed the extension of governmental activity. As teachers, we have helped habituate a new generation to such expressions as “the service state,” “positive government,” and “the new belief in the common man.” As scholars, we have followed with interest and approval the successive steps by which jurists have brought these activities within the framework of the written constitution of a federal state. As theorists, we have given to personal insecurity an honored place in the new psychopathological chapter in our evolving political philosophy. As citizens, we have played our part in planning and administering social welfare policies.

Extensive destruction and damage to communities in the aftermath of large-scale disasters such as hurricanes, floods, and earthquakes can cause substantial disorder in social and economic activity. The ensuing repercussions to social and economic systems lead to considerable uncertainty in continuing existing construction projects and implementing new reconstruction is problematic for accurately determining construction costs and making appropriate investment decisions. A large-scale disaster magnifies the importance of empirically examining variations in construction costs. Therefore, the overarching objective of this research is to analyze submitted unit price bids for superpave asphaltic concrete line items for highway projects let in the state of Louisiana after hurricanes Katrina and Rita. We employ two-way analysis of variance and a cumulative sum (CUSUM) control chart to monitor and detect changes in submitted unit price bids for hurricane- and non-hurricane-impacted areas. The results of the CUSUM control chart indicate that unit price bids for asphalt line items in the impacted areas significantly increased immediately after Hurricane Katrina and Rita hit the Gulf of Mexico, and those in the non-hurricane-impacted areas significantly increased six months after the hurricane. The findings of this research enable transportation agencies to more closely estimate the cost of rebuilding highway projects and make more-informed investment decisions for highway recovery programs in the aftermath of large-scale disasters.

Meeting popular expectations for social welfare delivery is one of the pillars upon which the current Russian regime bases its legitimacy. At the same time, the authorities try to transfer responsibility and costs to citizens and transfer service delivery to commercial actors. This article addresses the relationship between welfare reform and political stability in Russia. The discussion is based upon case studies of three large-scale reforms of pension, education and housing policies in 2014–2019. The reforms are analyzed in the light of mechanisms often referred to as “neo-liberal”: public budgets are relieved by making citizens pay more out of their own pockets, and tasks that used to be public are transferred to non-state actors or people’s self-organizing. The article identifies how the population reacts to the introduction of such mechanisms. It discusses the extent to which core reform mechanisms are challenged and original reforms modified in response to resistance.
