The climate of a city influences the ways in which its outdoor spaces are used. Especially public spaces intended for use by pedestrians and cyclists, such as parks, squares, residential and shopping streets, and foot- and cycle-paths will be used and enjoyed more frequently when they have a comfortable and healthy climate. Due to a predicted global temperature rise, the climate is likely to be more uncomfortable in the Netherlands, especially in summer, when an increase in heat stress is expected. As the phenomenon of urban heat islands (UHI) aggravates heat stresses, the effects will be more severe in urban environments. Since the spatial characteristics of a city influence its climate, urban design can be deployed to mitigate the combined effects of climate change and UHI’s. This paper explores these effects and tries to provide tools for urban design and strategies for implementation. Consequently, the applicability of the design tools is tested in a design for two existing Dutch neighbourhoods.

Singapore is a multi-racial island nation. The three main ethnic groups are Chinese, Malays, and Indians in respective descending numbers. Prior to the extensive provision of public housing, they lived in either of two forms of housing: timber houses with roofs of "atap"—a form of palm leaves, corrugated zinc plates or asbestos sheets, or rows of shophouses of more permanent materials, such as brick and mortar, and later concrete. The shophouses were found almost exclusively in the central area, while the former was found in ubiquitous semi-rural Chinese villages "kampongs"—the Malay word for village—or urban squatter.

Analysis of property sales in the vicinity of 1,294-acre Pennypack Park in Philadelphia indicates a statistically significant rise in land value with closeness to park, when allowance is made for effect of type of house, year of sale, and special characteristics such as location on corner of block. Location rent due to the park ranges from approximately $11,500 per acre 40 feet from the park to $1,000 at 2,500 feet. It accounts for 33 percent of land value at 40 feet, 9 percent at 1,000 feet, and 4.2 percent at 2,500 feet. Each acre of parkland may be said to generate a value of $2,600 in location rent.

This paper examines intermediate, semi-enclosed urban spaces and investigates the potential creation of environmental diversity when such spaces are integrated in urban design. More specifically, it focuses on the links between architectural characteristics of semi-enclosed spaces and their thermal performance. The paper identifies major types of semi-enclosed spaces and monitors their thermal performance in northern and southern Europe. The results showed that a wide range of thermal conditions, namely cooler conditions during summer and warmer conditions during winter can be experienced in both regions. Moreover, the thermal variation, which was identified, is linked with the spatial identity of each space and it is argued that the degree of enclosure as well as the orientation and the urban context are significant temperature determinants. Intermediate, semi-enclosed urban spaces should be regarded as important urban components that could increase the thermal and spatial diversity of the urban fabric and therefore contribute to a more fulfilling and comfortable environment.

The main objective of the present quasi-experi- mental study was to examine the influence of culture (Swedish vs Japanese) and environmental attitude (urban vs open-air person) on participants’ thermal, emotional and perceptual assessments of a square, within the PET (physiological equivalent temperature) comfortable inter- val of 18–23°C. It was predicted that persons living in different cultures with different environmental attitudes would psychologically evaluate a square differently despite similar thermal conditions. Consistent with this prediction, Japanese participants estimated the current weather as warmer than did Swedish participants and, consistent with this, they felt less thermally comfortable on the site, although participants in both countries perceived similar comfortable thermal outdoor conditions according to the PET index. Compared to the Japanese, the Swedes estimated both the current weather and the site as windier and colder, indicating a consistency in weather assessment on calm-windy and warm-cold scales in participants in both cultures. Furthermore, Swedish participants felt more glad and calm on the site and, in line with their character (more glad than gloomy), they estimated the square as more beautiful and pleasant than did Japanese participants. All this indicates that thermal, emotional and perceptual assessments of a physical place may be intertwined with psychological schema-based and socio-cultural processes, rather than fixed by general thermal indices developed in line with physiological heat balance models. In conse- quence, this implies that thermal comfort indices may not be applicable in different cultural/climate zones without modifications, and that they may not be appropriate if we do not take into account the psychological processes involved in environmental assessment.

What determines whether people consider an environment to be safe or unsafe? In two studies, we employed a multi-level model to examine how safety-related environmental characteristics and individual characteristics influence people's perception of the safety of night-time urban environments. Both studies support previous findings highlighting a key role for environmental appraisals of entrapment (perceived escape possibilities), prospect (perceived overview over a scene), and concealment (perceived environmental affordance of hiding places). More importantly, the studies provide a systematic investigation of person-environment interaction in the safety appraisal process. Our results reveal substantial individual variability in susceptibility to safety-related environmental characteristics (Study 1) and identify an interaction between individual characteristics and appraisals of environmental characteristics (Study 2). Additionally, while both studies replicate an effect of biological sex on safety appraisals, we show that this effect is mediated by trait anxiety, a psychological variable reflecting the propensity to experience anxiety.

Problems encountered in public open space provision in the urban context are investigated through a case study of the Chicago metropolitan region. Correlation and regression analyses are utilized in an attempt to explain local public open space acreage levels in terms of readily available data. Park district directors, chief municipal executives, forest preserve and conservation district directors are surveyed and interviewed in order to gain more qualitative insights. Governmental regulations in general and funding allocation practices for the region are examined for any effect on provision levels. Basic impediments to public open land provision are identified, and several solution strategies are suggested.

This article examines the effects of walkability on property values and investment returns. Walkability is the degree to which an area within walking distance of a property encourages walking for recreational or functional purposes. We use data from the National Council of Real Estate Investment Fiduciaries and Walk Score to examine the effects of walkability on the market value and investment returns of more than 4,200 office, apartment, retail and industrial properties from 2001 to 2008 in the United States. We found that, all else being equal, the benefits of greater walkability were capitalized into higher office, retail and apartment values. We found no effect on industrial properties. On a 100-point scale, a 10-point increase in walkability increased values by 1–9%, depending on property type. We also found that walkability was associated with lower cap rates and higher incomes, suggesting it has been favored in both the capital asset and building space markets. Walkability had no significant effect on historical total investment returns. All walkable property types have the potential to generate returns as good as or better than less walkable properties, as long as they are priced correctly. Developers should be willing to develop more walkable properties as long as any additional cost for more walkable locations and related development expenses do not exhaust the walkability premium.

Urban sociologists and criminologists have maintained housing’s importance in providing individuals with a sense of security within their neighborhood. Yet it remains unclear whether all types of housing provide this sense of safety in the same way. This article provides an analysis of the relationship between dwelling type and fear of crime. Data from the 2009 Canadian General Social Survey are analyzed. Results suggest that living in a multiunit dwelling has no statistically significant impact on fear of crime in the neighborhood; however, individuals living in high-rise and low-rise residences are less likely to be fearful of crime while at home in the evening. One possible explanation for these findings is the fortress effect: High-rise buildings isolate individuals in physical space, providing security in the home, and creating physical and social distance from the rest of the neighborhood. The implications of these findings are discussed.

Experience is conceptualised in both academic and policy circles as a more-or-less direct effect of the design of the built environment. Drawing on findings from a research project that investigated people’s everyday experiences of designed urban environments in two UK towns, this paper suggests at least two reasons why sensory encounters between individuals and built environments cannot in fact be under- stood entirely as a consequence of the design features of those environments. Drawing from empirical analysis based on surveys, ethnographic ‘walk-alongs’ and photo-elicitation interviews, we argue that distinct senses of place do depend on the sensory experiencing of built environments. However, that experiencing is significantly mediated in two ways. First, it is mediated by bodily mobility: in particular, the walking practices specific to a particular built environment. Secondly, sensory experiences are intimately intertwined with perceptual memories that mediate the present moment of experience in various ways: by multiplying, judging and dulling the sensory encounter. In conclusion, it is argued that work on sensory urban experiencing needs to address more fully the diversity and paradoxes produced by different forms of mobility through, and perceptual memories of, built environments.

Latino immigrant presence in urban neighborhoods has been linked with reduced neighborhood cohesion in social disorganization-based ethnic heterogeneity hypotheses and enhanced cohesion in immigration revitalization approaches. Using the 2000–2002 Los Angeles Family and Neighborhood Survey and the 1994–1995 Project on Human Development in Chicago Neighborhoods Community Survey, we explore the association between Latino immigrant concentration and both levels of, and agreement about, neighborhood collective efficacy. Findings from multilevel models with heteroskedastic variance indicate that Latino immigrant concentration exhibits a nonlinear association with collective efficacy. At low levels, increases in Latino immigrant concentration diminish collective efficacy, consistent with a heterogeneity hypothesis. The negative association between Latino immigrant concentration and collective efficacy declines in magnitude as immigrant concentration increases and, particularly in LA, becomes positive beyond a threshold, consistent with an immigration revitalization effect. We also find an inverse nonlinear pattern of association with the variance of collective efficacy. At low levels, increasing Latino immigrant concentration increases the variance of collective efficacy (reflecting more disagreement), but beyond a threshold, this association becomes negative (reflecting increasing agreement). This pattern is observed in both LA and Chicago. The prevalence of social interaction and reciprocated exchange within neighborhoods explains a modest proportion of the Latino immigrant concentration effect on mean levels of collective efficacy in Chicago, but does little to explain effects on the mean in LA or effects on the variance in either LA or Chicago. These findings offer insight into the complex role Latino immigrant presence plays in shaping neighborhood social climate.

Research has identified several factors that affect fear of crime in public space. However, the extent to which gender moderates the effectiveness of fear-reducing measures has received little attention. Using data from the Chicago Transit Authority Customer Satisfaction Survey of 2003, this study aims to understand whether train transit security practices and service attributes affect men and women differently. Findings indicate that, while the presence of video cameras has a lower effect on women's feelings of safety compared with men, frequent and on-time service matters more to male passengers. Additionally, experience with safety-related problems affects women significantly more than men. Conclusions discuss the implications of the study for theory and gender-specific policies to improve perceptions of transit safety.

Building on Whyte’s work on livable places, the present study developed a four-item scale to assess visitability and used it to test whether three attributes identified by Whyte—seating, food, and triangulation—increase visit- ability.The study used color slides of three plazas altered for the presence or absence of each attribute. Sixty participants (23 men and 37 women) rated slides of the plazas on each of four items on the Perceived Visitability Scale (PVS). The four items had high interitem reliability, and each item and their composite had high interobserver reliability.The visitability ratings showed that plazas with seats, food, or sculpture had higher scores than plazas without those elements; and the combination of seats and sculpture had higher scores than either element alone. Contradicting Whyte, there was no statistically significant effect of gender. Seats, sculpture, and the perceived compatibility of elements with one another may improve plaza visitability.

The paper explores the extent to which inhabitants of Abu Dhabi find ways circumvent official notions of order as it pertains to the use of open public spaces in the city. To that effect, the study focuses on informal modes of urbanity examining and mapping various forms of informal activities that still persist in the city. The study relies on field research carried out in Abu Dhabi's central area, content analysis of media reports, and interviews with officials and city residents. This will be contextualized and situated within the overall urban development Abu Dhabi. These contemporary modes of informal urbanism will be mapped through a survey of the city's public spaces. A series of vignettes offers a portrayal of the diverse ways in which residents have constructed an alternative order. The overall aim is to construct a 'narrative of informality'—a view from below offering a more substantive assessment of people's interaction with, and relation to, the built environment. The paper begins with a theoretical framework aiming at situating the study within the overall discourse known as 'informal urbanism' the study of the everyday which, while prevalent to various degrees within urban theory, has been receiving renewed emphasis. The overall value for mapping activities both at the level of urban theory and for the urban development of Dhabi is discussed in the conclusion.

Informal commerce, characterized by market and street trading activities, thrives in the central areas of many Latin American cities. Focusing on the neglected spatial dimension of informal commerce, the paper traces its considerable expansion in the historic centre of Quito in Ecuador since the early 1970s and examines the issues which have prompted municipal intervention. An early municipal response involves some attempts at redistribution of informal commerce, justified by essentially functional issues such as hygiene and congestion. However, the introduction of conservation policy and the way this policy evolved to embrace a broad concern for the urban environment is associated with the emergence of an aesthetic/cultural discourse in attitudes towards informal commerce. The authorities are increasingly motivated towards ‘selling’ a new image of the historic centre and encouraging new economies oriented towards the tourist and a relatively wealthy clientele. Moves to exclude informal commerce have concentrated on the most visible spaces, particularly those of the principal squares. Although informal trade hidden from view continues to thrive, only time and further research will show whether the re‐presentation of the historic centre and the promotion of new economies will finally effect the exclusion of informal commerce as a culmination of long‐term efforts to control its occupation of space.

The present study investigated the effects of public art on visual properties and affective appraisals of landscapes. Undergraduate and graduate students sequentially viewed landscapes with or without public art and rated each one for visual properties and affective appraisals. Study 1 revealed that the presence of public art reduced pleasantness of the natural scene, but did not reduce that of the urban scene. In Study 2 focusing on the urban landscapes, the t-tests showed that public art consistently yielded greater arousal and the visual properties related with arousal level (e.g., complexity), whereas for pleasantness and the visual properties related with pleasantness (e.g., legibility) the scores varied with the public artworks. Adopting the experimental design that systematically combined 4 landscapes with 2 pieces of public art, Study 3 revealed that the affective quality of public art had more influence on the landscapes than the compatibility between public art and the landscapes.

Despite the fact that virtual environments are increasingly deployed to study the relation between urban planning, physical and social disorder, and fear of crime, their ecological validity for this type of research has not been established. This study compares the effects of similar signs of public disorder (litter, warning signs, cameras, signs of vandalism and car burglary) in an urban neighborhood and in its virtual counterpart on the subjective perception of safety and livability of the neighborhood. Participants made a walking tour through either the real or the virtual neighborhood, which was either in an orderly (baseline) state or adorned with numerous signs of public disorder. During their tour they reported the signs of disorder they noticed and the degree to which each of these affected their emotional state and feelings of personal safety. After finishing their tour they appraised the perceived safety and livability of the environment. Both in the real and in the simulated urban neighborhood, signs of disorder evoked associations with social disorder. In all conditions, neglected greenery was spontaneously reported as a sign of disorder. Disorder did not inspire concern for personal safety in reality and in the virtual environment with a realistic soundscape. However, in the absence of sound disorder compromised perceived personal safety in the virtual environment. Signs of disorder were associated with negative emotions more frequently in the virtual environment than in its real-world counterpart, particularly in the absence of sound. Also, signs of disorder degraded the perceived livability of the virtual, but not of the real neighborhood. Hence, it appears that people focus more on details in a virtual environment than in reality. We conclude that both a correction for this focusing effect and realistic soundscapes are required to make virtual environments an appropriate medium for both etiological (e.g. the effects of signs of disorder on fear of crime) and intervention (e.g. CPTED) research.

This research examined the effect of concealment (environmental cues), presence or absence of people recreating (social cues), and gender on individuals’ fear of crime in a community park setting. Using a 7-point single- item indicator, 732 participants from two samples (540 park visitors and 192 college students) rated their estimates of fear of crime to 24 photographic representations of a community park. All three, two-factor interaction effects were significant in the park visitor sample, but in the student sample, only the Presence of People Recreating × Gender effect was significant. These results suggest that social and environmental cues may jointly affect fear experiences and that the presence of other people recreating in a park environment and the gender of an individual may influence fear of crime when recreating alone in a park setting. Implications include design and management techniques that promote safe park environments.

The existing literature on the social, personal, and health consequences of high density housing is unclear regarding the significance that can be attached to the physical features of housing. The present study, which is based on interview information collected in Hong Kong, is able to control for deprivations and stresses related to "poor housing," and it is also able to distinguish superficial from more severe measures of personal strain. High densities are seen to have very little effect on individuals and families, although there is a suggestion that congestion is a potentially significant stress.

Public monuments traditionally appear in high contrast to their landscapes, an effect that sets aesthetic, ideological and social distances. However, Manmale, counter-monuments, and counter-hegemonic monuments (eg the AIDS quilt, Rachael Whiteread’s House, Melbourne’s Another ViewWalking Trail, Tiananmen’s Goddess of Democracy, or Maya Lin’s Vietnam Memorial), challenge the norms of monuments in visuality, fixedness, and permanence, and suggest intricacies which mediate the interactivity of art, site and passers-by. In this paper, I consider three counter-hegemonic monuments in Vancouver, British Columbia – all installed in 1997/98 and all dealing with the issue of violence – sited within one neighbourhood. Via archival research, interviews, and extensive participant observations investigating how the monuments actually function in social memory rituals, I discovered that the characteristics of publicness in the landscapes that lay ‘beneath and before’ the monuments deeply affected their origins, designs, and current uses.
