Mitigating Urban Heat: Developing a Climate Smart Toolkit for Liveable, Sustainable Precincts to Address Environmental Monitoring and Better Building Design
Urban heat islands (UHI) are a major contributor to increasing global warming, which are metropolitan areas that are significantly warmer than their surrounding rural areas. Land temperatures in densely developed city centres can be as much as 10 degrees Celsius higher than the surrounding forested landscape. Besides increased energy needs, UHI effects urge urban planners to reconsider the design and energy assessments of buildings in urban areas due to the storage and release of heat energy. Increasing temperatures also contribute to serious health issues, e.g., through the transmission of infectious diseases, which diminishes the liveability in UHI areas.
We propose to study the mechanisms of UHI and the impact of mitigation strategies on the built environment taking a data-centric approach. We will design a toolkit for the development process using the Northshore Hamilton precinct as our testbed . The toolkit, a Climate Smart Precinct in a Box, will be transferable across multiple precincts and adaptable to local conditions in each precinct. Our goal is to build a scalable model that leverages open source technology, the Internet of Things (IoT), smart sensing environments, data sharing models, and advanced analytics to address the issue of urban heat for more liveable and sustainable communities. To achieve this, we follow a methodology that is divided into two parts, technology and people, and has five components: data collection, data analysis, develop insights, design patterns, and impact.
Methodology to develop a Climate Smart Precinct in a Box
First, we plan to collect sensor data to measure different types of data such as temperature, solar radiation, humidity, and wind speed velocity, which will be realized through the implementation of LoRaWAN-enabled environmental monitoring systems provided by Meshed , an IoT technology provider. Second, we will integrate and analyse data using UrbanPulse, an IoT analytics platform provided by [ui!] . We will employ an open standards approach to design an advanced data visualisation interface. Third, we will develop actionable insights through workshops, focus groups, and interviews with key stakeholders. Fourth, we will leverage the insights in other locations and develop a policy informatics framework through an abstraction of the insights and a development of design patterns. This will help to reiterate the process and share design knowledge. Finally, we will be able to measure and evaluate the impact of the Climate Smart Precinct in a Box as it pertains to reducing UHI effects effectively and efficiently.
Abstract: Cities, like any complex adaptive systems, may become increasingly fragile if not properly managed. To date, the literature has focused primarily on the examination of cities within fragile countries. This has resulted in a dearth of studies that have looked at how developed (or even advanced) cities that operate in relatively stable countries and/or environments might allow unresolved issues to accumulate in the city: degrading its ability to function. Studying fragility in developed cities is a worthwhile undertaking given their economic, social, and political significance. This paper puts forth a conceptual framework to understand the nature of fragile cities in the developed world. Our framework frames fragility as a function of unresolved fractures of social compacts that degrades a city’s ability to function over time and stress exacerbates its effects. Drawing on over two dozen incidents from developed cities, we ground the framework and illustrate its value.

What Do Parents Value in a Child Care Provider? Evidence from Yelp Consumer Reviews - IZA Discussion Paper No. 11741. Click here to download.
This paper exploits novel data and empirical methods to examine parental preferences for
child care. Specifically, we analyze consumer reviews of child care businesses posted on the
website Yelp.com. A key advantage of Yelp is that it contains a large volume of unstructured
information about a broad set of child care programs located in demographically and
economically diverse communities. Thus our analysis relies on a combination of theoryand
data-driven methodologies to organize and classify the characteristics of child care
that are assessed by parents. We also use natural language processing techniques to
examine the affect and psychological tones expressed in the reviews. Our main results are
threefold. First, we find that consumers overall are highly satisfied with their child care
provider, although those in higher-income markets are substantially more satisfied than
their counterparts in lower-income markets. Second, the program characteristics most
commonly evaluated by consumers relate to safety, quality of the learning environment,
and child-teacher interactions. However, lower- and higher-income consumers evaluate
different characteristics in their reviews. The former is more likely to comment on a
program’s practical features, such as its pricing and accessibility, while the latter is more
likely to focus on the learning environment. Finally, we find that consumers in lowerincome
markets are more likely to display negative psychological tones such as anxiety and
anger in their reviews, particularly when discussing the nature of their interactions with
program managers and their child’s interactions with teachers.
