As countries aim to reduce resource consumption and greenhouse gas (GHG) emissions, Whole Life Carbon Assessment (WLCA) has become a vital method for quantifying embodied and operational GHG emissions. However, few studies have conducted WLCA on an urban scale, often addressing operational or embodied GHG emissions in isolation without considering their cumulative impact. This study introduces a city-wide WLCA framework to assess the potential recyclable materials of urban building stock, using Singapore as a case study with 5915 public residential buildings. Upfront GHG emissions are calculated from material intensity and building information, while operational emissions are based on energy use …

Cities worldwide are adopting green building certification policies to meet sustainability and decarbonization targets in the building sector. However, the effectiveness of green certifications remains contested due to the difficulty of decomposing multiple influencing factors on building energy consumption. This study proposes an econometrics-based ex-post analysis framework to assess the effectiveness of green building certification policies in energy savings and identify driving factors by decomposing multiple influential factors. The proposed framework incorporates time-fixed effect models to examine factors driving the adoption of green building certifications, and causality analysis to quantify the effectiveness. Applying the framework to analyze a panel dataset …
Local Problems, Global Solutions? Making It Rain In Hong Kong C. 1890-1930, Fiona Williamson
Local Problems, Global Solutions? Making It Rain In Hong Kong C. 1890-1930, Fiona Williamson
Research Collection College of Integrative Studies
The late nineteenth to early twentieth century saw a small but dedicated rise in experimental rainmaking. The possibility that humanity might one day be able to control the weather – especially to alleviate drought – was very attractive to governments and private investors. The late nineteenth century was an era of scientific optimism and a number of rainmaking experiments across the world had brought the potential for weather control out of the realms of discourse and literature and further into tangible near-future science. There has been a small but thorough historiographical literature on this subject, focusing largely on American, British, …

The prediction of thermal and noise-based preferences in the urban context is valuable in characterizing interventions to mitigate the challenges of health, productivity, and satisfaction of urban dwellers. The growth of crowd-sourced data and data-driven techniques provides an opportunity to increase the understanding of which machine learning models are most accurate and applicable for this context. This paper outlines the results of a machine learning competition aiming to enhance the accuracy of predicting human comfort in the city context. The competition asks contestants to use contextual data to predict noise distraction and thermal preference in various indoor and outdoor spaces. …
Political Ecologies Of Storage For The 21st Century, Sayd Randle, Matthew Archer
Political Ecologies Of Storage For The 21st Century, Sayd Randle, Matthew Archer
Research Collection College of Integrative Studies
New resource storage arrangements are proliferating rapidly both in terms of physical infrastructures-for the storage of things like "clean" energy, nuclear waste, carbon dioxide, fresh water, and data-and as part of a set of discursive moves that reinforce a vision of a near future world in which problems of climate change mitigation and adaptation in particular (but also issues like energy security, water security, industry growth, etc.) are solved through eco-modernist techno-fixes. This Symposium sketches the contours of a framework we term political ecologies of storage. In doing so, we treat storage as both a potent imaginary and a concrete …
Gamification For Air Quality Education: A Systematic Literature Review, Abdollah Baghaei Daemei, Ruggiero Lovreglio, Zhenan Feng, Daniel Paes, Clayton Miller
Gamification For Air Quality Education: A Systematic Literature Review, Abdollah Baghaei Daemei, Ruggiero Lovreglio, Zhenan Feng, Daniel Paes, Clayton Miller
Research Collection College of Integrative Studies
Air quality is crucial to our health and well-being, as poor air quality can lead to serious health problems such as asthma, allergies, and other respiratory conditions. Educating people about air quality is key to improving awareness and taking action to reduce its negative effects. Gamification offers a creative and engaging way to deliver educational content by incorporating game elements into the learning experience. However, despite its potential, there has been no review of how gamification has been used for air quality education. Thus, this review aims to fill that gap by systematically examining how gamification is applied to air …

Hong Kong is a hyper-dense coastal city that has long learned to live with a potentially disastrous extreme weather event: tropical cyclones. This was largely a reactionary process, with investments in soft and hard infrastructure made in the aftermath of devastating tropical cyclones. While the experiences of devastating tropical cyclones remain strong in the collective memory of the city, Hong Kong's present-day resilience has led to complacency, especially among the general public. We suggest that Hong Kong may be caught in a resilience trap, where previous success in building resilience may be hindering the city's ability to adapt to the …
Urban Heat And Within-City Residential Sorting, Stefan Borsky, Eric Fesselmeyer, Lennart Vogelsand
Urban Heat And Within-City Residential Sorting, Stefan Borsky, Eric Fesselmeyer, Lennart Vogelsand
Research Collection College of Integrative Studies
This study presents new causal evidence on how urban heat contributes to sorting within a city. We estimate a discrete choice residential sorting model that includes census-tract fixed effects and controls for open space and green coverage to analyze how differences in urban heat at the census-tract level influence the location choices of New York City homeowners given their race, ethnicity, and income. Our results show clear patterns of residential sorting, with whites and high-income households outcompeting other racial/ethnic groups and low-income households for housing in cooler neighborhoods. Our counterfactual exercise, inspired by Cool Neighborhoods NYC, reveals that heat-mitigation policies …

Global climate science needs to address a fundamental challenge: the mismatch between the scales of anthropogenic processes driving change and the resulting climate impacts. While projected climate changes and impacts are global in extent, the drivers of this change, and the exposure to its impacts, are concentrated in densely populated urban areas. Despite occupying only 1–3% of the land, urban areas are home to most of the world’s population and responsible for ~70% of current greenhouse gas emissions [1]. By 2050, an additional 2.5 billion people are expected to live in urban areas, with up to 90% of this growth …
Impact Of Rainfall On Air Temperature, Humidity And Thermal Comfort In Tropical Urban Parks, Juan A. Acero, Philip Carl Kestel, Hieu T. Dang, Leslie K. Norford
Impact Of Rainfall On Air Temperature, Humidity And Thermal Comfort In Tropical Urban Parks, Juan A. Acero, Philip Carl Kestel, Hieu T. Dang, Leslie K. Norford
Research Collection College of Integrative Studies
Urban areas in hot and humid tropical regions are frequently exposed to uncomfortable thermal levels. A well-developed urban heat mitigation strategy is increasing vegetation infrastructure, even though the impact differs based on regional climate. In this study we have evaluated the impact of rainfall on air temperature, humidity and thermal comfort inside a large urban park in Singapore, based on measurement campaigns. A comparison between the park and an urban site is presented. Results show that rainfall significantly reduces air temperature and improves thermal comfort levels, not only right after the rain event but also in the after-event dry period. …

Evaluating Urban Fire Vulnerability And Accessibility To Fire Stations And Hospitals In Austin, Texas, Akhil Mandalapu, Kijin Seong, Junfeng Jiao
Research Collection College of Integrative Studies
Anthropogenic climate change has increased the frequency and intensity of fires. Despite their widespread consequences, current research has largely overlooked urban fires and their associated vulnerability. This study seeks to identify patterns of fire vulnerability, map out areas with high fire vulnerability and limited access to fire stations and hospitals, and ultimately determine the factors contributing to increased fire incidents. Principal Component Analysis was used to develop a fire vulnerability index comprising variables capturing health status and socio-environmental factors. Enhanced 2-step floating catchment area (E2SFCA) analysis was conducted to determine relative accessibility to resources such as hospitals and fire stations. …

Future urban planning requires context-specific integration of spatial design and microclimate especially for tropical cities with extreme weather conditions. Thus, we propose a Combined Spatial-Climatic Design approach to assess impact of urban densification on annual outdoor thermal comfort performance employing ENVI-met simulations for Singapore. We first consider building bylaws and residential site guidelines to develop eight urban-density site options for a target population range. We further classify annual weather data into seven weather-types and use them as boundary conditions for the simulations. Comparing such fifty-six combined spatial-climatic simulation outputs by analyzing Outdoor Thermal Comfort Autonomy, we report the influence of …
Multiethnic Elites And The Management Of Tropical Heat In Colonial Malaya, Circa 1870s-1930s, Claire Lowrie, Nicole Tarulevicz, Fiona Williamson, Charmaine H. Lam
Multiethnic Elites And The Management Of Tropical Heat In Colonial Malaya, Circa 1870s-1930s, Claire Lowrie, Nicole Tarulevicz, Fiona Williamson, Charmaine H. Lam
Research Collection College of Integrative Studies
This article considers the responses of multiethnic urban elites to living with tropical heat in colonial Malaya by analysing attitudes towards the meteorological study of temperature, commercial cold storage and hill stations. A transcolonial and transimperial approach is used to illustrate that interest in managing and monitoring temperature was slower to develop in Malaya compared with other tropical colonies. The article also considers how access to methods of ameliorating heat was shaped by colonial hierarchies based on ideas of race and class.
Atmosphere, Environment, Society: The Typhoon Vulnerability Nexus In Early Twentieth-Century Hong Kong, Fiona Williamson
Atmosphere, Environment, Society: The Typhoon Vulnerability Nexus In Early Twentieth-Century Hong Kong, Fiona Williamson
Research Collection College of Integrative Studies
By looking at how typhoon risk was managed in early twentieth-century colonial Hong Kong, this article argues that bringing a historical lens to the discussion of the human-climate-environment nexus is an essential part of studies of resilience and vulnerability. It interprets physical evidence of the strength of a natural event against human factors, including structural and social vulnerabilities and governance. Investigating two of the deadliest typhoons to have hit Hong Kong's shores (1906 and 1937), this article notes that social vulnerabilities played a major part in turning the typhoon of 1937 into a worse disaster than 1906, despite advances in …

Vulnerability To Climatic And Environmental Disaster And Change In The Indian Ocean World, Philip Gooding, Fiona Williamson, Julie Babin
Research Collection College of Integrative Studies
At the time of writing (Autumn 2022), extreme weather is devastating large swathes of the Indian Ocean World (IOW). In Pakistan, especially around the Indus River in Balochistan and Sindh, floods are causing severe distress. So far, more than 1,300 people have been killed, half a million more have been left homeless and there has been around $30 billion worth of damage to infrastructure. Nevertheless, even as the floods are projected to worsen during the second half of the south-west monsoon season, there are already fights on multiple spatial scales to shape the narratives about the root causes of the …

Green Stormwater Infrastructure: A Critical Review Of The Barriers And Solutions To Widespread Implementation, Bardia Heidari, Sarah Priscilla Randle, Dean Minchillo, Fouad H. Jaber
Research Collection College of Integrative Studies
Rapid urbanization, aging infrastructure, and climate change impacts have put a strain on existing stormwater drainage systems. One commonly acknowledged solution to relieve such stress is Green Stormwater Infrastructure (GSI). Interest in GSI technology has been growing. However, the level of implementation in many areas around the world lags behind the interest level. This study aims to critically review the body of literature from the last decade to determine the main barriers to wide adoption and the offered solutions to overcome them. Based on a review of 92 peer-reviewed journal articles published between 2012 and 2022, we classify barriers and …

Research Collection College of Integrative Studies
Virtual simulations of future extreme weather events may prove an effective vehicle for climate change risk communication. To test this, we created a 3D virtual simulation of a future tropical cyclone amplified by climate change. Using an experimental framework, we isolated the effect of our simulation on risk perceptions and individual mitigation behaviour for a representative sample (n = 1507) of the general public in Hong Kong. We find that exposure to our simulation is systematically associated with a relatively small decrease in risk perceptions and individual mitigation behaviour. We suggest that this is likely due to climate change scepticism, …
Heat And Colonial Weather Science In The Straits Settlements C. 1820-1900, Fiona Williamson
Heat And Colonial Weather Science In The Straits Settlements C. 1820-1900, Fiona Williamson
Research Collection College of Integrative Studies
Historical explorations of tropical heat in a colonial context have largely focussed on two interconnected spheres: colonial perceptions of place and body or, the implications of heat on different bodies in medical thought and practice. This paper seeks to move the discussion towards a history of colonial scientific thought about heat as component of weather and of escalating nature-induced hazards, studied in the observatory or meteorological department. A central theme is to think about heat in its relationship to nascent meso-scale atmospheric knowledge, meteorological theory and, as a by-product of urbanisation and land-use change. In so doing, it conceptualises the …

El Niño And The Human-Environment Nexus: Drought And Vulnerability In Singapore 1877-1911, Fiona Williamson
Research Collection College of Integrative Studies
This chapter brings a climatic perspective to the study of Singaporean history by exploring the impacts of the strong El Niño inspired droughts of 1877, 1902 and 1911. The narrative focuses on unpacking the nexus of nature-inspired versus human-induced vulnerability to drought within the contexts of colonial urbanisation and looks at the short-to medium-term impacts of the events on society. It also explores how such events inspired new questions about the climate and regional teleconnections, as a wealth of evidence became available due to the increasingly connected nature of scientific institutions, scientific literature, and communications systems across the Indian Ocean …

On Aqueducts And Anxiety: Water Infrastructure, Ruination, And A Region-Scaled Anthropocene Imaginary, Sayd Randle
Research Collection College of Integrative Studies
This paper explores popular expectations for and meanings of the U.S. West's environmental future, as articulated through recent artistic representations of the Los Angeles's expansive water provision network. Weaving together material from participant observation and readings of creative works, I show how infrastructural imagery is used to index anxieties about a future of water scarcity. Presenting familiar, currently functional water infrastructures as ruins-in-the-making, these artists use the physical stuff of water provision networks to advance critiques of longstanding modes of development and the material basis of urban-rural relations in the U.S. West. Doing so, these imagined ruins draw the global-scale …

Climate Change And Technology: Examining Opinion Formation Of Geoengineering, Christopher L. Cummings, Sonny Rosenthal
Research Collection College of Integrative Studies
The term “climate change” has evolved from what was originally a technical term employed by scientists into a symbolic referent involving complex social, political, and moral considerations that have spurred worldwide debate. As evidence of the anthropogenic influence on the Earth’s climate has grown over the past few decades, climate change has come to be viewed as a primary challenge to be confronted in the twenty-first century. Geoengineering, or climate engineering, is a set of large-scale technological interventions proposed to offset climatic changes. This study seeks to understand which factors contribute to, or alternatively, detract from public acceptance of geoengineering …
