Arcosanti is a prototype city being built based on the visionary architect Paolo Soleri’s principles of Arcology which integrates architecture with ecology. Arcology proposes a compact three-dimensional urban form to provide a lean alternative to the unsustainable urban sprawl city form found in most of America. In its reduction of dependence on the automobile, reliance on pedestrian transportation, proximity to nature and proposal to have agriculture integrated into the city, Arcology is a vision of Green Urbanism. The design of Arcosanti incorporates Biophilic principles that preserve the biodiverse natural landscape, has a compact organic form, and functions with a circular metabolism that is analogous to nature when complete. Arcosanti, located in central Arizona, was begun in 1970 as an urban laboratory, and has been constructed by over 7,000 workshop volunteers over the past 45 years. Following Soleri's death in 2013, the Cosanti Foundation has established a Strategic Planning Steering Committee to help guide the continued development of Arcosanti as a prototype Arcology. The Strategic Plan will provide a framework for future organization and development. This article examines how the concept of Arcology and the development of the Arcosanti prototype encompasses principles of Green Urbanism and sustainable development.

The world’s urban population is rapidly growing, now exceeding its rural population, and is expected to reach 70% of the world’s total by 2050. Research in environmental psychology increasingly supports the Biophilia Hypothesis which holds that our connection with Nature is innate. Thus, how do we maintain a human connection to Nature in an increasingly urbanising world? This paper is based on current research work and explores the boundary between built and natural environments, specifically how visual connectivity to Nature affects how people use social spaces, compared to spatial connectivity. Case study work is being undertaken at Arcosanti urban laboratory in the Arizona desert. Arcosanti construction began in 1970 to test Paolo Soleri’s Arcology Theory which proposes, in opposition to sprawling cities, a new form of urban setting which is compact with tightly restricted horizontal growth, leaving the surrounding natural environment as undeveloped “wilderness”. Through development of a Space/Nature Syntax methodology applied within a uniquely compact urban form, this research attempts to understand how designing to maintain the instinctive bond with Nature can affect social interaction and inform future design choices within built environments. This paper describes the development of, and basis for, the Space/Nature Syntax methodology, presents initial findings achieved through its recent application at Arcosanti, and outlines future work. Initial analysis indicates that visual connectivity to Nature is a significant influence on certain types of social interactions when compared to spatial connectivity, although more research is needed to verify the level of significance.

This paper reviews the prospect of a radical redefinition of the relationship between society, technology, and Nature as posited within Paolo Soleri’s Arcology theory, and anticipates a transformative social order and environmental setting in support of sustainability as demonstrated within the urban laboratory Arcosanti. It locates the roots of Soleri's ecological architecture within a rejection of urban sprawl emerging from his early apprenticship with Frank Lloyd Wright at Taliesin West in Arizona, and argues that his own theoretical model, in presenting a fusion of architecture and ecology, prefigures a utopia of transcendence and offers a more rational planned response to the challenges of our age, while offering environmental movements a vision of what a sustainable urban future might look like. The paper argues that the positive utopian tendencies in Soleri’s work should be reaffirmed and, at the same time, it underlines an urgent need for multi-aspect and multi-disciplinary research, and postgraduate education, to be undertaken at Arcosanti, to test the parameters of micro- and macro-structures within alternative models of ecological design. In concluding the paper gives acknowledgement to the ongoing work of the Cosanti Foundation’s Board of Directors and its new Strategic Plan Steering Committee, and their commitment to attract renewed levels of financial and human resource in support of the urban laboratory’s unfinished business.

Sustainability has been an important topic in many disciplines over two decades, and its urgency is rising. At the same time, a conceptual understanding of sustainability remains rather vague, posing a challenge for research in this area. Nevertheless the term ‘sustainability’ is increasingly used in the context of ecological, economic, and social studies. In green economics it is often used interchangeably with the term ‘sustainable development’, defined by the World commission on environment and development in 1987 as, “development which meets he needs of the present without compromising the ability of future generations to meet their own needs.” this underlines sustainability’s ethical dimension where a normative view implies treating sustainability as a form of intergenerational equity and fairness. The question of intergenerational equity constitutes a growing concern, and our obligation to future generations requires us to look beyond short-term public policy preoccupations to anticipate building a better future for all.

A multitude of diverse attributes is required for effective urban performance at various scales ranging from the immediate context of public buildings to central urban spaces, and from urban corridors to residential neighbourhoods. Following their earlier works (GRIERSON, 2014; MUNRO and GRIERSON, 2016; SALAMA, 2011; SALAMA and WIEDMANN, 2013; and SALAMA et al., 2016) the guest editors frame these qualities under a cycle of three main symbiotic pillars: the imagined, the measured, and the experienced, which contribute to the development of insights that elucidate various parameters for exploring urban performance. These three pillars stem from the Lefebvrian arguments and his theory on the production of space, which postulates a triadic relationship of three different but related types of spaces: the conceived (Imagined), the perceived (measured) and the lived (experienced).

There is an urgent need to develop a systematic tool for urban design in the cities of the Klang Valley, Malaysia. Sustainable Development Goal 11 (SDG11) proposes ideas to make cities and human settlements inclusive, safe, resilient and sustainable. This paper approaches this goal through land use, integrated into an effective connectivity network. It offers a scientific and systematic approach. The research employs Space Syntax of the University College London as a tool for urban analysis and the principles of Sustainable Street Networks developed by the Congress of New Urbanism to respond to connectivity issues.

The paper employs empirical research through case studies. A systematic literature review is conducted on the diversified applications of the Space Syntax correlations, which steered the fundamental analysis of the elements of deconstruction to structure and land use. Space Syntax and Sustainable Street Network characteristics were the essential research methods. It is important to note that these data a new finding on the Syntactic Maps of the two case study cities.

The paper summarises a set of results on (1) international comparison of spatial intelligence, (2) patterns from the Eastern cases and (3) theoretical guidelines for spatial intelligence through the Syntax by offering key characteristics of the New Urbanism principles, which could be considered, while revitalising the cities in the Klang Valley, Malaysia.

The findings are specific and applicable to the oriental contexts. However, such results have been further compared to the Western context.

The study develops a toolkit for urban planners and designers and architects in Klang Valley, Malaysia.

The research has focused and will add value for SDG11: Sustainable Cities and Communities. Theoretically, the paper offers insights to urban design readers.

It is important to note that the data itself is a new finding on Syntactic Maps of the two case study cities. The investigated setting is unique, and the first attempt in generating a Space Syntax map to the cities of Klang Valley, and the findings, therefore, offer a new set of knowledge-base to the city planners, urban designers, researchers and architects.

Proximity to nature is essential to a child’s development. Well-designed educational environments are crucial to supporting this proximity, particularly in the early years of schooling. The purpose of this paper is to measure children’s experiences of nature within three primary school spaces at various locations in Glasgow, Scotland. The methodology for measuring children’s visual and non-visual sensory experiences is developed to evaluate the connection between naturalness values and spatial environmental qualities across varying “Child–Nature–Distance” ranges.

The approach associates children’s multiple layers of sensory modalities with particular attributes of the spatial environment within primary schools to determine the level of naturalness that children experience, in both internal and external spaces.

The study finds that children’s experiences are significantly influenced by factors relating to urban setting, built environment master planning, architectural features and interior design.

Apart from primary school architecture for children, this methodology could be fully developed to the comprehensive human–nature relationship under the impacts of physical features and societal of other diversified environments in a future study. However, the offering reasonable primary school architecture for a proper children’s multi-sensorial experience with natural environment cannot thoroughly established with a quantitative aspect by the present study only. More qualitative research is recommended to examine the process of altering from “cause” to “perceived” nature of users’ cognitions, attitudes and behaviours within the exposure proximity to nature.

The methodology for measuring visual and non-visual sensorial experiences of nature, and its application to children’s learning and leisure spaces within primary school architecture could offer a tool for assessing current schools, and evaluating future design proposals for new schools.

The authors argue that the applicationof this method can support design decision making for refurbishing schools at the micro level, and in planning urban development involving proposals for new schools at the macro level.
