Abstract

Purpose

Given the distinct and unique climates in these countries, research conducted in other parts of the world may not be directly applicable. Therefore, it is crucial to conduct research tailored to the specific climatic conditions of Australia and New Zealand to ensure accuracy and relevance.

Design/methodology/approach

Given population growth, urban expansions and predicted climate change, researchers should provide a deeper understanding of microclimatic conditions and outdoor thermal comfort in Australia and New Zealand. The study’s objectives can be classified into three categories: (1) to analyze previous research works on urban microclimate and outdoor thermal comfort in Australia and New Zealand; (2) to highlight the gaps in urban microclimate studies and (3) to provide a summary of recommendations for the neglected but critical aspects of urban microclimate.

Findings

The findings of this study indicate that, despite the various climate challenges in these countries, there has been limited investigation. According to the selected papers, Melbourne has the highest number of microclimatic studies among various cities. It is a significant area for past researchers to examine people’s thermal perceptions in residential areas during the summer through field measurements and surveys. An obvious gap in previous research is investigating the impacts of various urban contexts on microclimatic conditions through software simulations over the course of a year and considering the predicted future climate changes in these countries.

Originality/value

This paper aims to review existing studies in these countries, provide a foundation for future research, identify research gaps and highlight areas requiring further investigation.

Abstract

Purpose

The preservation of historic urban centres prevents anarchic development of the city and ensures a harmonious evolution of the urban form. It also improves the quality of life in the context of climate and environmental change. Morphological and geometric indicators of the urban fabric are key parameters in the formation of external microclimates. They provide a positive effect on the thermal comfort of pedestrians. The objective of this work is to study the impact of the site morphology on the external microclimate and to understand the relationship between the subjective perception and the objective quantification of the thermal environment. The result of this study has allowed us to propose solutions for the creation of a microclimate favourable to the appropriation of outdoor spaces. The authors finally propose guidelines for the design and rehabilitation of the historic site based on the establishment of links between the site's configuration, microclimatic conditions and users' perceptions.

Design/methodology/approach

Part of this study included the analysis of the microclimate of the historic “Bab El Hadid” district of the City of Tlemcen, by developing a questionnaire survey and a numerical simulation validated by measurements of the microclimate the authors made on site. To complete this task, the authors applied the Envi-met 4.1 model during the coldest month of the winter and the hottest month of the summer. Urban parameters are represented at different measurement points characterised by a variability of the sky view factor (SVF).

Findings

The results presented in terms of average expected the predicted mean vote (PMV) voting, solar access and air temperature. They show that thermal conditions are directly related to the SVF, the height/width ratio (H/L) of streets as well as the orientation of urban canyons. The points located in the streets facing North–South, present an acceptable performance. Streets shaded by trees with a canyon aspect ratio of between 1.18 and 1.70 reduce heat stress in outdoor spaces. The PMV models discussed provide information on the most appropriate locations for pedestrians. The authors have proposed urban orientations that could limit unfavourable conditions in outdoor spaces. They are useful for architects and urban planners in the design and rehabilitation of historic centres.

Originality/value

In Tlemcen, the microclimate is not taken into account in the design and rehabilitation of urban fabrics. For this specific purpose, the authors want to stress in the research the importance of safeguarding urban heritage through the renewal of the old city and the bioclimatic rehabilitation of its urban spaces.

Abstract

Purpose

The purpose of this paper is to move beyond the stage of analysis of exclusively physical microclimatic phenomena and extending ourselves to the study of the impact of the microclimate environment on the user behavior in public spaces. This paper will open up new opportunities for the development of urban open spaces and facilitate the decision-making for urban decision-makers, city managers and planners to make the right urban planning decision.

Design/methodology/approach

The methodology for identifying the links between microclimatic quality of urban routes and behaviors was developed on the basis of the results obtained from field surveys carried out in nine public urban areas of the city of Biskra, three urban space are located in a traditional urban fabric (the medina) and the other five in new urban areas, in the two climatic seasons (winter, summer) of 2019. For this exploratory research, two types of instruments were used to collect data from environmental and human monitoring.

Findings

Improving microclimatic conditions in urban spaces can allow people to spend more time outside, with the possibility of increasing their social cohesion. The overall objective of this research is to better understand the impact of microclimatic characteristics on pedestrian behavior of nine selected public urban spaces in the city of Biskra, Algeria. To characterize this impact, the authors developed an approach based on crossing data of field surveys, including structured interviews with a questionnaire and observations of human activities (video recordings), as well as microclimate monitoring, conducted during the two climatic seasons (winter, summer) 2019. The analysis of the results allowed to verify the impact of the two climatic seasons (winter, summer) on the variation in the density of occupancy of the different urban areas studied and the duration of the user stations. The authors also illustrated that the number of individuals higher in the traditional urban spaces of the city of Biskra or the conditions of climate comfort are more comfortable than the urban spaces in the new urban areas of the city of Biskra during the summer, which is the season most problematic.

Originality/value

In recent years, there has been a proliferation of scientific studies on the subject of control of microclimatic characteristics and, in particular, on the consideration of the thermal comfort of persons by qualitative analysis, prediction and representation of the perception of external environments. Improving microclimatic conditions in urban spaces can allow people to spend more time outside, with the possibility of increasing their social cohesion. This study highlights the importance of climate-conscious urban design and design flexibility. Urban environments can be modified in summer and winter to provide a better outdoor thermal environment for users. In addition, this study also shows the importance of harmony between microclimate and urban design. Such harmony can be achieved by including requirements for a climate-conscious urban design in the planning regulations for cities in arid zones.

Abstract

Purpose

Due to the predicted global temperature rise and local expansion and densification of cities, Urban Heat Islands (UHI) are likely to increase in the Netherlands. As spatial characteristics of a city influence its climate, urban design could be deployed to mitigate the combined effects of climate change and UHIs. Although cities are already experiencing problems during warm-weather periods, no clear spatial means or strategies are available for urban designers to alleviate heat stress. The paper aims to discuss these issues.

Design/methodology/approach

There is a lack of knowledge on cooling effects that can be achieved through urban design in Dutch neighbourhoods. In this paper, the cooling effects of various design measures are compared on the level of urban blocks and neighbourhoods, with a focus on a 1960s neighbourhood in Amsterdam-West. The cooling effects are simulated by means of the microclimate model ENVI-met, here the effects on air temperature and physiological equivalent temperature will be evaluated.

Findings

The use of green, and a higher roof albedo in particular, seem to perform well as cooling measures. Combinations of cooling measures do not necessarily result in better performance and might even counteract other cooling effects. However, combinations of measures that lead to an increase in the environmental temperature show the largest heating.

Research limitations/implications

Effects of green roofs and facades are beyond the scope of this study, though future suggestions for this research will be included.

Originality/value

The results add to the body of knowledge in the area of climate design enabling policy makers and designers to estimate the effect of simulated measures in comparable neighbourhoods and thus improve thermal comfort in outdoor spaces.

Abstract

Purpose

The article aims to describe the approach adopted within the framework of a multi-destination development project, the goal of which is to promote innovative technologies and methods to evaluate the environmental quality of an urban district under construction.

Design/methodology/approach

The approach lies in the integration of methodologies usually applied on an urban scale (microclimate well-being and air quality, study of air quality), and/or to the individual building (acoustic comfort evaluation), never before adopted for assessment of plots or districts, especially in the dynamic evaluation of the variables identified, all objectively measurable. This method of analysis has been tested on an area of about 255,000 m2, located in the former historic district of the Fiera di Milano, where a series of typical urban functions (residential, commercial and trade) are inserted within a large public park.

Findings

The success of the work is represented by indicators (air quality, acoustic performance and microclimate) that relate to the finished district and that can be compared with average values in the same city. The system may constitute a protocol capable of bringing benefits to local authorities.

Research limitations/implications

The limit is the need of data that support the dynamic simulation (external factors as vehicular traffic, general neighbourhood activity, pollutant emissions) corresponding to the different seasons. These data are not always available by the municipalities.

Practical implications

This type of assessment could be requested of developers/builders for complex projects, resulting in changes to the initial plan if the assessment identifies critical issues related to the design choices (orientation of buildings, quality and presence of green areas, traffic emissions inside the urban district, etc.), with the ultimate goal of creating neighbourhoods with better environmental conditions.

Originality/value

The research produces solutions addressed to the Italian situation, but it identifies systems and methods used in other countries.

Abstract

Purpose

First, the contributions of spatial characteristics to microclimate were analyzed. And the results from mobile measurements were compared to those from fixed measurements to examine accuracy of mobile method. Air temperature and physiologically equivalent temperature (PET) profiles were plotted to explore the impacts of the spatial characteristics of that urban square and local street.

Design/methodology/approach

This research investigates the effects of urban canyons and landscape on air temperature and outdoor thermal comfort in an open square in Seoul, Korea, a city of diverse thermal environments. Mobile field measurements were carried out to obtain local meteorological data based on higher spatial resolution.

Findings

On a day in October under clear sky, air temperature and PET differences of up to 1.77 °C and 9.6 °C were observed at 2 p.m. and 3 p.m., respectively. These were mainly from the impact of shading effects caused by surrounding obstacles. The current layout and volume of vegetation in the square seemed not effective for reducing air temperature and improving thermal comfort, which needs further study.

Originality/value

The authors tested a way to investigate time delay when using mobile measurements by correcting measured local data using adjacent meteorological observatory data. The findings of and limitations on mobile station-based field measurement and analysis are discussed herein.

Abstract

Purpose

This paper critically analysed 195 articles with the objectives of providing a clear understanding of the current City Information Modelling (CIM) implementations, identifying the main challenges hampering the uptake of CIM and providing recommendations for the future development of CIM.

Design/methodology/approach

This paper adopts the PRISMA method in order to perform the systematic literature review.

Findings

The results identified nine domains of CIM implementation including (1) natural disaster management, (2) urban building energy modelling, (3) urban facility management, (4) urban infrastructure management, (5) land administration systems, (6) improvement of urban microclimates, (7) development of digital twin and smart cities, (8) improvement of social engagement and (9) urban landscaping design. Further, eight challenges were identified that hinder the widespread employment of CIM including (1) reluctance towards CIM application, (2) data quality, (3) computing resources and storage inefficiency, (4) data integration between BIM and GIS and interoperability, (5) establishing a standardised workflow for CIM implementation, (6) synergy between all parties involved, (7) cybersecurity and intellectual property and (8) data management.

Originality/value

This is the first paper of its kind that provides a holistic understanding of the current implementation of CIM. The outcomes will benefit multiple target groups. First, urban planners and designers will be supplied with a status-quo understanding of CIM implementations. Second, this research introduces possibilities of CIM deployment for the governance of cities; hence the outcomes can be useful for policymakers. Lastly, the scientific community can use the findings of this study as a reference point to gain a comprehensive understanding of the field and contribute to the future development of CIM.

Abstract

How are our cities confronting the challenges posed by a warming climate, the loss of biodiversity, and the increasing urban heat island effect? ― This chapter discusses the opportunities and benefits of applying the concepts of renaturalization and rewilding of cities. It introduces nature-based solutions (NBS) in urban planning that are integrated with the aim to enhance urban resilience and to slow down the biodiversity decline, which can be applied in two areas: through the conception of new green neighborhoods and through the regeneration and regreening of existing but neglected parts of the city, such as postindustrial brownfields or economically weak districts.

Contact to nature is essential for human existence, urban well-being, and a good quality of life. Green spaces in cities – big or small – all contribute to health and well-being. However, many cities do not offer residents easy access to green space within the city. Improving better access and extending gardens and parks will deliver a large number of benefits, such as ecosystem services, better water management for enhanced urban flood control, and slowing down the biodiversity loss, with the potential to restore damaged ecosystems. Furthermore, additional green space and NBS help to keep cities cool during heat waves and improve the urban microclimate.

In this context, NBS and regreening can generate significant benefits for citizens, improve urban health and well-being, and offer an opportunity to effectively deploy nature to resolve major societal challenges ― such as social inclusion, food security, and disaster risk reduction. However, it is essential that the design of NBS is fully integrated with other complementary planning interventions and seeks synergies across all sectors.

Abstract

Purpose

Although conformable devices are commonly designed to couple with the human body for personalized and localized medicine, their applications are expanding rapidly. This paper aims to delineate this expansion and predict greater implications in diverse fields.

Design/methodology/approach

Today’s device technologies continue to face fundamental obstacles preventing their seamless integration with target objects to effectively access, evaluate and alter self-specific physical patterns, while still providing physical comfort and enabling continuous data collection. Due to their extreme mechanical compliance, conformable devices permit the query of signals occurring at interfaces so as to decode and encode biological, chemical and mechanical patterns with high resolution, precision and accuracy. These unique and versatile capabilities allow for a marked change in the approach to tackling scientific questions, with the ability to address societal challenges at large.

Findings

Here, this study highlights the current state of these devices in a wide range of fields, such as interactive teaching, textiles, robotics, buildings and infrastructure, agriculture, climate and space, and further forecasts essential features of these devices in the near future.

Originality/value

This study justifies conformable devices’ growing utility through a novel quantitative analysis methodology that indexes peer-reviewed journal articles based on specific keywords, whereby this study tracks keyword frequency over time across specific fields in conjunction with conformability-like topics. The resulting trends’ trajectories provide the foundation for this study’s future projections. This study concludes with a perspective on the possible challenges concomitant with a ubiquitous presence of these technologies, including manufacturing, wireless communication, storage, compression, privacy and sharing of data, environmental sustainability, avoidance of inequality and bias and collaboration between stakeholders at all levels of impact.

Abstract

Purpose

This study aims to compare the local climate characteristics of Angkor Wat, Borobudur and Prambanan parks and determine effective strategies for mitigating thermal conditions that could suit Borobudur and Angkor Wat.

Design/methodology/approach

The study employed local climate zone (LCZ) indicators and ten-year historical climate data to identify similarities and differences in local climate characteristics. Satellite imagery processing was used to create maps of LCZ indicators. Meanwhile, microclimate models were used to analyze sky view factors and wind permeability.

Findings

The study found that the three tropical large-scale archaeological parks have low albedo, a medium vegetation index and high impervious surface index. However, various morphological characteristics, aerodynamic properties and differences in temple stone area and altitude enlarge the air temperature range.

Practical implications

Based on the similarities and differences in local climate, the study formulated mitigation strategies to preserve the sustainability of ancient temples and reduce visitors' heat stress.

Originality/value

The local climate characterization of tropical archaeological parks adds to the number of LCZs. Knowledge of the local climate characteristics of tropical archaeological parks can be the basis for improving thermal conditions.
