Mutualistic relationships versus hyper-efficiencies in the sustainable building and city

The quest for sustainability in the design and development of buildings and cities has expressed itself predominantly as a pursuit of ever-greater efficiency. Urban systems have been developed to achieve energy and resource savings in an attempt to eliminate their environmentally negative impacts. The end goal would seem to be to make buildings and cities virtually invisible within the context of the natural environment and to extract humanity from that which is natural. This approach could be termed as a hyper-efficiency sustainability model. In this approach, the impacts of human beings and their functional systems are seen as contaminants that need reduction or removal. Although driven by a desire to preserve the Earth’s natural systems, such an approach ultimately creates greater division between humanity and nature and may not bring sustainability. As an alternative to a hyper-efficiency model of sustainability, a model should be pursued that focuses more on developing an integrative relationship between civilization and environment akin to mutualism in biology. Such an approach, which could be termed as a mutualistic sustainability model, incorporates natural systems and elements into the structures and functions of buildings and cities, with the goal of achieving cooperative and positive interaction between humanity and nature. Such integration can create opportunities to support living organisms and biological systems in an ecologically contributive manner, while fulfilling human infrastructural needs. It offers a more positive alternative to efficiency based strategies and has the potential to establish a healthier and more productive relationship between humanity and the Earth’s natural systems. This paper elaborates on these two distinct approaches to sustainability and presents an examination of recent green building projects and green infrastructure projects. It analyses specific strategies and methods to contrast and compare manifestations of both approaches, providing valuable lessons and insights for designing sustainable buildings and cities.     

Ergonomics and sustainability in the design of everyday use products

The relationship between Ergonomics and Design is a key element in the sustainability project, as well as in many other areas of experimental design. In the Design for Sustainability field, Ergonomics is a strategic factor for design culture innovation, providing designers with the necessary knowledge and skills regarding human characteristics and capabilities, as well as user needs and desires during use and interaction with products in work activities and everyday life. Ergonomics is also a strategic innovative factor in design development and manufacturing processes. In fact, ergonomics provides a methodological approach in user-product interaction evaluation processes through the use of participatory design and survey methods, user trials, direct observation, savings and resource conservation, etc.On the other hand, design offers solutions able to interpret user needs and expectations, at the same time suggesting new behaviors and lifestyles.In Design for Sustainability, the ergonomic and user-centered approach contributes greatly to lifestyles and innovative use of products--making it possible to understand and interpret real people needs and expectations in their everyday actions and behavior.New consumption patterns, new awareness of lifestyles, energy source consumption, purchasing methods and consumption style etc. can be supported by design innovation, responding to expressed and unexpressed user needs. With this in mind, the ergonomic approach represents the starting point for design choices and at the same time, a tool for assessing their appropriateness and effectiveness.     

Ergonomics and design for sustainability in healthcare: ambient assisted living and the social-environmental impact of patients lifestyle

This work presents considerations on Ergonomics and Design for Sustainability in the healthcare field based on research experiences of the Technology and Design for Healthcare (TeDH) research group of INDACO (Industrial design, communication, arts and fashion) department of Politecnico di Milano. In order to develop a multidisciplinary approach to design able to answer to specific user needs such as elderly in an environmental sustainable way (1) this paper shows the results we achieved concerning ergonomics and environmental impact in product development (2), the extension of this approach to interior and home design and the advantage of the application of Information Communication Technologies (ICT). ICT can help people with special needs to make their everyday life easier and more safe, at the same time, ICT can make social-environmental impact of everyday behavior evident and can be applied to manage sustainability. The specific theme is thus to integrate ergonomics and sustainability competences in the development of Ambient Assisted Living through a Product- Service System approach. The concept of product service system has the potential to improve product performances and services, establish new relations and networks with different actors in order to satisfy user needs and apply a systems approach considering environmental, social and economic factors in the users' environment.     

Vertical greening systems, a process tree for green façades and living walls

This study shows that greening the building envelope with vertical greening systems such as climbing plants or living wall systems provides ecological and environmental benefits. Contemporary architecture in fact is increasingly focusing on vertical greening systems as a means to restore the environmental integrity of urban areas, biodiversity and sustainability. Applying green façades, which is an established feature of contemporary urban design, can offer multiple environmental benefits on both new and existing buildings and can be a sustainable approach in terms of energy saving considering materials used, nutrients and water needed and efficient preservation of edifices. To provide a full perspective and a viable case study on vertical greening systems a process tree is developed throughout this research. Elaborating the process tree has proved to be a useful methodology to analyse main parameters as climate and building characteristics, avoid damages and maintenance problems caused by inappropriate design, and compare different elements such as technologies, materials, durability, dimensions, and plant species employed.     

The human component of sustainability: a study for assessing "human performances" of energy efficient construction blocks

This paper presents an applied research aimed at understanding the relevance and the applicability of human related criteria in sustainability assessment of construction materials. Under a theoretical perspective, human factors consideration is strongly encouraged by building sustainability assessment methods, but the practice demonstrates that current models for building sustainability assessment neglect ergonomic issues, especially those ones concerning the construction phase. The study starts from the observation that new construction techniques for high energy efficient external walls are characterized by elements generally heavier and bigger than traditional materials. In this case, high sustainability performances connected with energy saving could be reached only consuming high, and then not very much sustainable, human efforts during setting-up operations. The paper illustrates a practical approach for encompassing human factors in sustainability assessment of four block types for energy efficient external walls. Research steps, from block selections to bricklaying task analysis, human factors indicators and metrics formulation, data gathering and final assessment are going to be presented. Finally, open issues and further possible generalizations from the particular case study will be discussed.     

An Integrated Approach to Managing Change

Complex systems often involve a huge number of variables whose interdependence must be taken into account. This makes the adoption of an integrated approach essential for the proper management of a wide range of aspects related to human life, from social matters to the environment. In particular, this paper takes into consideration three different experiences in which the use of an integrated approach represented the most effective response for managing the evolving realities we took into consideration. We focused on the issue of land management, with particular attention to the problem of monoculture in Brazil. Then we analyzed the attempted cooperation between the States of the Aral Sea area for efficient water management of the basin and, finally, we dealt with the matter of energy efficiency and how the production of home integrated systems could lead to a better rationalization of energy consumption in the near future.      

Frames,organisations, and practices as social components of energy

The paper examines three social dimensions of energy. The first one is cognitive; energy is a way of knowing, a macro-concept which works as a frame. Moreover, energy is conceived as a social product; its physical aspects are inextricably bound up with human interactions and meaning attributions. The second dimension is energy organisation. Energy is an instrument used by human beings in order to achieve a goal. In that sense, energy can be assimilated to a technology: that is, a set of knowledges, tools, and actions assembled according to certain rules and traditions. Of energy as organisation it is interesting to consider how it becomes an institution. Its third dimension is practical: it guides our behaviour. This meaning sums up the other two. Energy consumption makes it possible to understand different lifestyles, different logics of action, different habits or customs. It is intrinsic to the most common practices. Worries about consumption or resources depletion are included in some practices of which energy is one of the most important components. The paper concludes with a comment on the energy crisis as a test for the illustrated multidimensional scheme.     

Same time,same place: analyzing temporal and spatial trends in urban metabolism using proximate counties in the North Carolina Triangle

Urban ecosystems’ demands for energy and materials are rapidly growing, as is the burden of wastes produced in utilizing these resources. Current consumption patterns are considered unsustainable, as they degrade resource stocks and ecosystem services that support human populations. While an urban metabolism approach is useful in analyzing resource flow dynamics that affect sustainability, challenges regarding data resolution and temporal and spatial consistency have been persistent issues in both time-series and comparative cross-sectional analyses. We envisioned that addressing these issues would allow a deeper examination of changes in metabolic trends and more robust comparison between urban ecosystems. To minimize inconsistencies, we conducted a time-series and cross-sectional metabolism analysis of three proximate urban ecosystems over a common time period. Our study compared the metabolism of Durham, Orange, and Wake Counties in North Carolina, USA using the highest available data resolution from 1985 to 2005. We found that high resolution temporal data made it possible to identify specific metabolic trends and suggest connections to changes in infrastructure, policy, and weather patterns using additional data resources. Analyzing proximate urban ecosystems over a common time period allowed us to identify the metabolic effects of policy, weather patterns, infrastructure, and waste management programs. In evaluating these outcomes, we demonstrate how urban metabolism analyses could be a valuable tool for management and planning related to resource and energy flows.     

A broader consideration of human factor to enhance sustainable building design

The link between ergonomic/human factor and sustainability seems to be clearly evidenced mainly in relation to social dimension of sustainability, in order to contribute to assure corporate social responsibility and global value creation. But the will to establish an equilibrated connection among used resources in human activities, supported by the sustainability perspective, evidences that the contribution of ergonomics/human factors can be effectively enlarged to other aspects, especially in relation to building design. In fact a sustainable building is meant to be a building that contributes, through its characteristics and attribute, to a sustainable development by assuring, in the same time, a decrease of resources use and environmental impact and an increase of health, safety and comfort of the occupants. The purpose of this paper is to analyze in a broader sense the contribution of ergonomic/human factor to design of sustainable building, focusing how ergonomics principles, methodology and techniques can improve building design, enhancing its sustainability performance during all phases of building lifecycle.     

The role of corporate social responsibility in strong sustainability

The aim of this paper is to analyze to what extent corporate social responsibility (CSR) contributes to strong sustainability, i.e. to what extent the use of natural resources and the environment is possible, given the current level of economic activity. We therefore examine responsibilities that corporations should take in order to fulfil the requirements of strong sustainability. Based on current CSR practices and theory as well as on businesses motivations regarding environmental and social investments, we will introduce the role of corporations in influencing consumption patterns. Furthermore, we will attempt to answer to what extent responsible corporate behaviour is determined by the current economic system.     

Analysis of strategic plans to assess planning for sustainability of comprehensive community initiatives

In order to achieve the intended impact on a community, comprehensive community initiatives must sustain programs once they have been implemented. However, planning for sustainability is challenging and is rarely incorporated in the planning process of an initiative. The current study examined 19 5-year plans developed during the planning phase of the Comprehensive Strategy for Serious, Violent and Chronic Juvenile Offenders. Quantitative and qualitative methods were employed to assess the extent to which the construct of sustainability was incorporated. The plan analysis was supplemented with results from other components of the complex evaluation design implemented as part of the process evaluation of Comprehensive Strategy. Results suggested that sustainability was not accounted for during the planning phase of this initiative. The implications of these findings, including the importance of planning for sustainability in order to achieve sustainability, are discussed.     

Ergonomics and education as a strategy for sustainable development in business

It is part of the vocabulary of organizations, and the agendas discussed the subject of "Sustainability", but there are few companies that implement practices or even know the means of implementing sustainable practices. The objective of this paper is to discuss an approach to education for sustainable development (ESD) based on the concepts and practice of ergonomics, as a consequence of this approach allows the implementation of integration initiatives focused on sustainability, such as eg. energy efficiency and consumer awareness thus allowing a means of reducing costs and operating expenses, increased competitiveness and significant contributions to corporate sustainability. There is also the inclusion of sustainability in corporate strategic planning, and their implications in the different spheres of the market.     

A MACROECONOMIC ANALYSIS OF ENERGY SUBSIDIES IN A SMALL OPEN ECONOMY

We construct a dynamic model of a small open economy to analyze the effects of large energy subsidies. The model includes domestic energy production and consumption, trade in energy at world market prices, as well as private and public sector production. The model is calibrated to Egypt and used to study reforms such as reductions in energy subsidies with corresponding reductions in various tax instruments or increases in infrastructure investment. We calculate the new steady states, transition paths to the new steady state, and the size of the associated welfare losses or gains. Our main results for a 15% cut in energy subsidies are: (1) Steady state gross domestic product drops in most of our experiments as less energy is used in production. (2) Steady state consumption rises in most of our experiments. (3) Welfare can rise by as much as 0.6% in consumption equivalent terms. (4) The largest gains in terms of output and of welfare can be obtained when savings from energy subsidy cuts are used to fund additional infrastructure investment.

Patterns of practice: a reflection on the development of quantitative/mixed methodologies capturing everyday life related to water consumption in the UK

There is a growing body of research arguing the relevance of practice approaches to understand resource consumption, and to highlight alternative pathways to sustainability. These practice approaches offer an alternative conceptualisation of demand and have been demonstrated largely by qualitative research, particularly in the work on water and energy consumption in the home. However, these historical narratives and qualitative research have not, to date, lead to the development of quantitative or mixed methodologies that could potentially reflect the diversity of performances of practice across populations in a more systematic way. This paper reflects, critically, on one such attempt to scale a practice-based perspective into a quantitative survey on water consumption and practice in homes in the south and South-East of England. The use of quantitative and mixed methodology has substantial potential – from translating practice-based research to policy; developing indictors to track patterns of practices as they change over time; and the exploration of methodologies that reflect the bundling and coordination of practices associated with water use inside and outside the home. The benefits and utility of such a methodological approach are highlighted as cautions and future research directions.     

Process evaluation of integrated West Nile virus surveillance in northern Italy: an example of a One Health approach in public health policy

West Nile virus (WNV) is endemic in the Po valley area in northern Italy. Regional health authorities have implemented integrated WNV surveillance following a One Health approach, based on collaboration between human, animal and environmental health institutions. We evaluated this integrated WNV surveillance system in Emilia-Romagna, Lombardy and Piedmont regions by means of a process evaluation. We examined the system’s implementation fidelity, dose delivered and received, reach, and we identified strengths and weaknesses in the system. Qualitative and semi-quantitative data were obtained from three regional focus groups. Data were discussed in a follow up focus group, where participants suggested recommendations for improving the surveillance system.Inter-institutional and interdisciplinary integration and the creation of a 'community of practice' were identified as key elements for effective surveillance. We identified differences in the degree of interdisciplinary integration in the three regions, likely due to different epidemiological situations and years of experience in surveillance implementation. Greater collaboration and sharing of information, public engagement and economic assessments of the integrated surveillance approach would facilitate its social recognition and guarantee its sustainability through dedicated funding. We demonstrate that a transdisciplinary research approach based on process evaluation has value for designing and fine-tuning integrated health surveillance systems.     

Understanding the Sustainability of Insurgency Conflict in Thailand

Abstract

This article seeks to model the insurgency conflict in the three southern border provinces of the Kingdom of Thailand: Pattani, Yala, and Narathiwat. In so doing, it will explore the sustainability of the conflict by representing it in terms of a conflict life cycle that is responsive to complexity and change. The cycle arises from the cybernetic viable systems theory of ‘living systems’, and is able to foster a better understanding of what is happening empirically on the social level in these provinces, in respect to a situation characterized as one of incessant conflicts. This conflict model that arises suggests that there is an interconnection between the agents involved, and their individual and interactive dynamics. The conflict involves five types of politically related behaviours that occur between two interactive agents: the state (engaged in searching for and making arrests of insurgents) and the insurgents (engaged in violent acts of shooting, bombing, and arson). These agents are studied to the end of being able to determine the precise interactive nature of the political conflict in which they are engaged. In carrying out this investigation both quantitative and qualitative approaches were used. The research was carried out in three stages. In the first stage, time series techniques were used to determine inferentially whether the conflict is both rational and involves interactive behaviours. Stage two adopts the Weibull distribution technique to assess the political conflict. In the third stage, a statistical analysis is conducted of the conflict situation in political terms. Finally, it is explained how the model and the methods used in this article may be used to deal with intractable conflict in other social environments, incidentally tracking the likelihood of conflicts being sustainable. Other agencies could utilize this approach in examining other political conflicts so as to be better able to prepare suitable approaches for coping with intractable conflicts to the end of fostering sustainable peace processes.     

Ten years of experience from interactive ergonomics projects

This paper highlights experiences from ergonomics projects, applying an interactive research approach. The aim of this paper is to summarise experiences from seven interactive ergonomics projects with the aim to improve ergonomics and organizational performance jointly. Results from these seven projects were analysed with a model for assessing sustainable change, including the factors active ownership, professional management, competent project leadership, and involved participants. All factors were found giving support to impact and sustainability of the change projects. However, the role of the researcher is difficult and demanding.     

Urban ecosystems and sustainable urban development—analysing and assessing interacting systems in the Stockholm region

In order to build competence for sustainability analysis and assessment of urban systems, it is seen as essential to build on models representing urban form, landuse and transportation, urban metabolism, as well as ecological processes. This type of analysis of interacting sub-systems requires an advanced model integration platform, yet open for learning and for further development. Moreover, since the aim is to increase urban experience with ecosystem management in the wide sense, the platform needs to be open and easily available, with high visualisation capacity. For this purpose, the LEAM model was applied to the Stockholm Region and two potential future scenarios were developed, resulting from alternative policies. The scenarios differed widely and the dense urban development of Scenario Compact could be visualised, destroying much of the Greenstructure of Stockholm, while Scenario Urban Nature steered the development more to outer suburbs and some sprawl. For demonstration of the need for further development of biodiversity assessment models, a network model tied to a prioritised ecological profile was applied and altered by the scenarios. It could be shown that the Greenstructure did not support this profile very well. Thus, there is a need for dynamic models for negotiations, finding alternative solutions and interacting with other models. The LEAM Stockholm case study is planned to be further developed, to interact with more advanced transport and land use models, as well as analysing energy systems and urban water issues. This will enable integrated sustainability analysis and assessment of complex urban systems, for integration in the planning process in Stockholm as well as for comparative sustainability studies between different cities, with the goal to build more sustainable urban systems and to increase urban experiences in ecosystem management.     

Ecologically unequal exchange: A theory of global environmental injustice

In this article, we review the theory of ecologically unequal exchange and its relevance for global environmental injustice. According to this theory, global political–economic factors, especially the structure of international trade, shape the unequal distribution of environmental harms and human development; wealthier and more powerful Global North nations have disproportionate access to both natural resources and sink capacity for waste in Global South nations. We discuss how the theory has roots in multiple perspectives on development, world‐systems analysis, environmental sociology, and ecological economics. We detail research that tests hypotheses derived from ecological unequal exchange theory on several environmental harms, including deforestation, greenhouse gas emissions, biodiversity loss, and water pollution as well as related human well‐being outcomes. We also discuss research on social forces that counter the harmful impacts of ecologically unequal exchange, including institutions, organizations, and environmental justice movements. We suggest that ecologically unequal exchange theory provides an important global political–economic approach for research in environmental sociology and other environmental social sciences as well as for sustainability studies more broadly.     

Where Do We Stand? Testing the Foundation of a Shared Site Intergenerational Program

Abstract

Shared site intergenerational care programs provide ongoing services simultaneously to old and young community members at a single facility, thereby, meeting the care needs of multiple generations. However, they face the challenge of sustainability common to all community-based programs. We employed the results management model to identify program elements that may enhance or inhibit sustainability of intergenerational programming at a shared site facility involving a child development lab school and adult day services program. The 4-step results management approach is a strengths-based model that supports community capacity and achievement of community and program goals. The current paper describes the first step in the results management approach, mapping the terrain, which involves gathering evidence of community needs and strengths. Focus groups were conducted with eleven staff members from both programs after a 4-month intergenerational program. The focus groups targeted the needs and strengths related to intergenerational programming. Respondents identified strengths that enhanced staff members' and clients' capacity for collaboration. These included affective and developmental benefits for both generations and strong partnerships between staff members. Respondents also identified factors that limited collaboration, such as the need for greater authority support and cross-training opportunities. Findings from our study have been used by program administrators to continue using the results management approach to further build intergenerational community and expand the scope of evaluating intergenerational shared site programs. Other intergenerational programs may utilize the results management model to enhance intergenerational programming and increase program sustainability.
