Long Wave Radiation Exchange For Urban Scale Modelling Within A Co-Simulation Environment, Clayton Miller, Daren Thomas, Jérôme Kämpf, Arno Schlueter
Long Wave Radiation Exchange For Urban Scale Modelling Within A Co-Simulation Environment, Clayton Miller, Daren Thomas, Jérôme Kämpf, Arno Schlueter
Research Collection College of Integrative Studies
This paper describes the implementation of long wave radiation (LWR) exchange as part of a co-simulation process of an urban scale simulation program, CitySim, and a building scale program, EnergyPlus. This coupling process was achieved through the use of functional mockup units (FMU) to exchange various weather, load, and environmental information between the two simulation engines. LWR is an important factor to exchange between the programs as CitySim has more advanced capabilities for radiation exchange calculations from a set of urban buildings and EnergyPlus has a more advanced building heating and cooling load calculation engine. The LWR exchange between surfaces …
Energy For Development: The Concept, Holmes J., Terry Van Gevelt
Energy For Development: The Concept, Holmes J., Terry Van Gevelt
Research Collection College of Integrative Studies
Worldwide, 1.3 billion people remain without access to electricity and 2.7 billion are still cooking on harmful and inefficient stoves1 . Many live in remote rural village communities, and until they have access to energy services, little progress can be made to develop and improve their lives2 . As United Nations Secretary-General Ban Ki-moon has stated, “energy is the golden thread that connects economic growth, increased social equity, and an environment that allows the planet to thrive”3 . Improving the lives of rural communities by developing smart villages is a concept analogous to the more familiar smart cities. The vision …
Where Does Bicycling For Health Happen? Analysing Volunteered Geographic Information Through Place And Plexus, Greg P. Griffin, Junfeng Jiao
Where Does Bicycling For Health Happen? Analysing Volunteered Geographic Information Through Place And Plexus, Greg P. Griffin, Junfeng Jiao
Research Collection College of Integrative Studies
Research on the role of bicycling for health through physical activity has been limited by the lack of information on where bicyclists ride. New big data sources available through smartphone-based applications provide a rich source to provide bicycle volume data more comparable to the scale of information available for automotive and public transit modes. In the case of smartphone apps for fitness tracking, results of this data can be used similar to the growing application of global positioning systems for automotive travel surveying. The authors evaluate data from Travis County, Texas for the purpose of determining where bicyclists ride, primarily …

The synchronized last mile logistics concept seeks to address, through coordinated collaboration, several challenges that hinder reliability, cost efficiency, effective resource planning, scheduling and utilization; and increasingly, sustainability objectives. Subsequently, the meeting of service level and contractual commitments are competitively impacted with any loss of efficiency. These challenges, against a backdrop of Singapore, can essentially be addressed in selected industry sectors through a better understanding of logistics structures; innovative supply chain designs and coordination of services, operations and processes coupled with concerted policies and supply chain strategies.
Forensically Discovering Simulation Feedback Knowledge From A Campus Energy Information System, Clayton Miller, Arno Schlueter
Forensically Discovering Simulation Feedback Knowledge From A Campus Energy Information System, Clayton Miller, Arno Schlueter
Research Collection College of Integrative Studies
Simulation model calibration has been long identified as a key means of reconciling the consumption and efficiency characteristics of buildings. A key step in this process is the creation of the actual diversity factor profiles for occupancy and various energy end uses such as lighting, plug-loads, and HVAC. Creation of these model inputs is conventionally a tedious process of site surveys, interviews or temporary sensor installation. Sometimes measured energy data can be used to create these schedules, however there are many challenges, especially when the sensor network available is large or unorganized. This paper describes a process applying a series …

Crowdsourcing Bicycle Volumes: Exploring The Role Of Volunteered Geographic Information And Established Monitoring Methods, Greg P. Griffin, Junfeng Jiao
Research Collection College of Integrative Studies
The recent interest in performance measures and new bicycle infrastructure development has triggered rapid advancements in monitoring methods for active transportation, but comprehensive monitoring programs for the bicycle mode are far from ubiquitous. This study evaluates the use of GPS survey data and a new crowdsourced volume dataset that may offer promise to extend the reach of limited counting programs. The authors integrated count data from 5 separate trail locations in Austin, Texas, with a previous survey using the CycleTracks smartphone app, and a new data product derived from a larger-scale use of the Strava fitness app. New crowdsourced methods …
Transnational Mobilities And The Making Of Creative Cities, Lily Kong
Transnational Mobilities And The Making Of Creative Cities, Lily Kong
Research Collection School of Social Sciences
This review essay on the literature on creative cities pays particular attention to the ways in which transnational mobilities contribute significantly to the making of such cities. The paper reviews critically both the literature and phenomena of creative cities and their transnational flows by framing the discussion around the mobility of ideas (creative economy/creative city discourse), the mobility of people (the migration of the creative class), the mobility of technology (the travel of the creative cluster and architectural iconism phenomena), the mobility of finances (capital and investment flows), and the mobility of images (transnational artistic collaborations and products).
From Cultural Industries To Creative Industries And Back? Towards Clarifying Theory And Rethinking Policy, Lily Kong
Research Collection School of Social Sciences
In this paper, I draw attention to the complexities and confusions in the shift in discourse and praxis from "culture industry" to "cultural industries" and then "creative industries." I examine how this "creative turn" is fraught with challenges, highlighting seven issues in particular: (i) the difficulties in defining and scoping the creative industries; (ii) the challenges in measuring the economic benefits creative industries bring; (iii) the risk that creative industries neglect genuine creativity/culture; (iv) the utopianization of "creative labour"; (v) the risk of valorizing and promoting external expertise over local small- and medium-scale enterprises in the building of "creative industries"; …

Multiscale Co-Simulation Of Energyplus And Citysim Models Derived From A Building Information Model, Daren Thomas, Clayton Miller, Jérôme Kämpf, Arno Schlueter
Research Collection College of Integrative Studies
We present an approach for rapidly assessing the performance of early design stage building information models (BIM) from both the building and urban systems scale. This effort builds upon two previously developed tools, the Design Performance Viewer (DPV) and the CitySim urban simulation engine. It couples them to produce a more informed model. The DPV is a plugin for Autodesk Revit Architecture that creates a model for the EnergyPlus building performance engine based on information contained in the BIM. We combine the two simulation engines using the Functional Mock-up Interface (FMI) co-simulation framework to improve the accuracy of both simulations. …

The Singapore housing market is unusual in its high homeownership rate, the dominance of HDB housing, and the extensive intervention of the government in regulating housing supply and demand in both the HDB and private housing sectors. Recent rapid population increases in a low interest rate and high global liquidity environment has resulted in accelerated house prices increases in Singapore. Earlier this year, the government launched “Our Singapore Conversation” of which discussion on housing policies constitutes one major component. This “conversation” comes in the wake of several consecutive rounds of measures to stabilize housing prices using various instruments. This paper …

Research Collection College of Integrative Studies
Building retrofit analysis in Switzerland traditionally relies on expert heuristics and best practices. These processes are not often supplemented by data or model-driven techniques that would enhance the accuracy and ability to quantify the impact of innovative technologies. We present a process of calibrated building energy model (BEM) analysis of a case study using a building information model (BIM) and measured data from a custom wireless sensor network. The case study is a mixed-use office and residential historically listed building in Zürich, Switzerland. A BIM model was first developed in Autodesk Revit and then extracted to an EnergyPlus model through …

Research Collection School Of Computing and Information Systems
Sensing social media for trends and events has become possible as increasing number of users rely on social media to share information. In the event of a major disaster or social event, one can therefore study the event quickly by gathering and analyzing social media data. One can also design appropriate responses such as allocating resources to the affected areas, sharing event related information, and managing public anxiety. Past research on social event studies using social media often focused on one type of data analysis (e.g., hashtag clusters, diffusion of events, influential users, etc.) on a single social media data …

Introduction: Religion And Place: Landscape, Politics, And Piety, Elizabeth Olson, Peter Hopkins, Lily Kong
Research Collection School of Social Sciences
In 2010, a 14-year-old boy was brutally murdered in a suburb outside of Rio de Janeiro when a group of skinheads observed him at a party and suspected that he might be gay (McLoughlin 2011). This scale of horrific homophobia is not uncommon in Brazil, where rates of violence against gays, lesbians, and transgendered people are reported to be amongst the highest in the world. A study conducted with the support of Grupo Gay da Bahia offers the conservative estimate of 260 gays killed in the country in 2010, indicating that rates doubled in only 5 years. The statistic sits …

Automation Of Common Building Energy Simulation Workflows Using Python, Clayton Miller, Christian Hersberger, Marcus Jones
Research Collection College of Integrative Studies
A valuable skillset for building industry professionals is proficiency in high-level, scripting languages that can automate and perform many common repetitive or technically intensive tasks. This application-focused paper emphasizes the use of the Python programming language in various workflows common to the building performance modeling and simulation process. Python is an open, powerful, and easy-to-learn scripting language with an emphasis on programmer productivity. While the highlighted applications themselves are notably ordinary amongst building simulation practitioners, the novelty of this discussion is in the speed and usefulness of new Python libraries and data analysis techniques. Four short examples are illustrated: simulation …
Do Singaporeans Spend Too Much On Housing?, Sock Yong Phang
Do Singaporeans Spend Too Much On Housing?, Sock Yong Phang
Research Collection School Of Economics
According to a 2011 IMF study, Singapore's level of government intervention in housing finance is the highest in the developed world (Slide 3). This level of intervention in housing finance has correspondingly produced the highest level of homeownership amongst advanced countries. This housing outcome is the result of our very unique HDB-CPF housing framework – an institutional framework that was established in the 1960s during the formative period of our country?s history (Slides 4 and 5). Singapore was, at that particular point in time, faced with a situation of chronic housing shortage, low homeownership rates and an underdeveloped housing mortgage …

Ambitions Of A Global City: Arts, Culture And Creative Economy In 'Post-Crisis' Singapore, Lily Kong
Ambitions Of A Global City: Arts, Culture And Creative Economy In 'Post-Crisis' Singapore, Lily Kong
Research Collection School of Social Sciences
This paper chronicles some of the key policies pertaining to the arts and culture in post-independent Singapore. A brief summary is first provided of the early (1960s and 1970s) cultural policy focusing on the harnessing of arts and culture for nation-building purposes, followed by the subsequent (1980s) recognition that the arts and culture had tourist dollar potential. The paper then expands on the cultural/creative economy policy of the 2000s, in which arts, heritage, media and design are recognized for their economic value (beyond their role in tourism to include their export value and their importance in attracting global workers). The …
Improbable Art: The Creative Economy And Sustainable Cluster Development In A Hong Kong Industrial District, Lily Kong
Research Collection School of Social Sciences
A noted Singapore-based cultural geographer and specialist on Asia analyzes the emergence and functioning of a unique artistic cluster in Hong Kong's Fotan light industrial district. The objective of the research is to understand how artistic work in the cluster, despite some challenges, has thus far proven sustainable in cultural, social, and economic terms. The findings of this case study permit further clarification of several dimensions of an emerging theory of cultural/creative clusters, which should be considered as distinct from business and industrial clusters. Selective comparisons between the Fotan cluster and the Moganshan Lu cluster in Shanghai demonstrate that cultural/creative …

This paper reviews the literature on cultural and creative spaces, and examines its merits and shortcomings in helping to explain how culture and creativity in the city are supported. Alternative ways of conceptualising cultural and creative spaces which emphasise the importance of networks and multi-scalar relationships and non-economic considerations will be examined.
Singapore’S Chinatown: Nation Building And Heritage Tourism In A Multiracial City, Brenda S. A. Yeoh, Lily Kong
Singapore’S Chinatown: Nation Building And Heritage Tourism In A Multiracial City, Brenda S. A. Yeoh, Lily Kong
Research Collection School of Social Sciences
This paper focuses on the pivotal role played by the state in refashioning the Chinatown landscape as part of both nation-building and heritage tourism projects, and the ensuing cultural politics. After a brief history of the creation of Singapore’s Chinatown, the paper discusses, first, Chinatown’s place in Singapore’s post-independence nation-building project and, second, the reconfiguration of the Chinatown landscape as a tourism asset. The final section reflects on the changing politics of place as Chinatown gains legitimacy in state discourses on heritage, tourism and multiculturalism, as well as in the popular imagination as an ethnic precinct par excellence.
Rethinking The Rural-Urban Divide In China’S New Stratification Order, Qian Forrest Zhang
Rethinking The Rural-Urban Divide In China’S New Stratification Order, Qian Forrest Zhang
Research Collection School of Social Sciences
I use a Marxist framework centred on the mode of production to conceptually analyze the changing stratification structure in today’s China with a focus on the changing nature of rural-urban inequality. As the state-managed tributary mode of production, once dominant under socialism, is being gradually eclipsed by the reviving petty-commodity mode of production and the newly emerged capitalist mode of production, both of which are market-based and enable the transfer of surplus from labour to capital, a new set of mechanisms are creating and sustaining rural-urban inequality in China. Rural-urban inequality – although still significant in its magnitude – is …
From Precarious Labor To Precarious Economy? Planning For Precarity In Singapore's Creative Economy, Lily Kong
From Precarious Labor To Precarious Economy? Planning For Precarity In Singapore's Creative Economy, Lily Kong
Research Collection School of Social Sciences
The important place of the oftentimes "hidden" independent worker, or freelancer, has been acknowledged in developed countries where the creative economy has grown. These creative workers do not belong to the traditional employment set-up organized around firms. Instead, they move from portfolio to portfolio, assignment to assignment, interspersing corporation-based jobs with periods of self employment. Their work offers freedom, independence and creative space, but has also been characterized as precarious, because the securities of old working patterns no longer hold. While governments in many countries and cities have become attracted to the potential of the creative economy, those that have …

Introduction: Contested Landscapes, Asian Cities, Lily Kong, Lisa Law
Research Collection School of Social Sciences
A decade and a half after Cosgrove and Jackson (1987) wrote their seminal piece on ‘new’ cultural geography, the discipline of geography has experienced a ‘cultural’ turn. Economic geography, for instance, has been infleected through perspectives that take on board cultural retheorisations (see Thrift and Olds, 1996; Thrift, 2000). Within urban studies, the acknowledgement of culture’s powers is not new (see, for example, Agnew et al., 1984). Yet, geographers scrutinising urban landscapes have moved the field, using some of the retheorised perspectives that Cosgrove and Jackson (1987) encapsulated. Of most pertinence to this volume is the retheorised notion of culture …

Modeling Of The Single Coil, Twin Fan Air-Conditioning System In Energyplus, Clayton Miller, Chandra Sekhar
Research Collection College of Integrative Studies
This paper outlines the conceptual development of a building energy simulation model for the Single Coil, Twin Fan Air Conditioning (SCTF) system in the whole building simulation program EnergyPlus. The SCTF system is a unitary, multi-zone system which conditions the outdoor ventilation and recirculated return air in two separate streams through a single compartmented cooling coil and supplies these unmixed streams via two variable speed fans and a dual duct arrangement to zonal mixing boxes. The main challenges addressed in EnergyPlus include the existing inability to concurrently simulate unmixed air streams within a centralized VAV system, supply and control outdoor …
Urban-Biased Policies And The Increasing Rural-Urban Expenditure Gap In Vietnam In The 1990s, Eric Fesselmeyer, Kien T. Le
Urban-Biased Policies And The Increasing Rural-Urban Expenditure Gap In Vietnam In The 1990s, Eric Fesselmeyer, Kien T. Le
Research Collection College of Integrative Studies
There was a significant and widening rural-urban gap during the economic boom in Vietnam in the 1990s. Using an econometric decomposition, we find that differences in individual characteristics such as education, ethnicity and age are the primary explanation for this widening gap, whereas differences in the returns to these characteristics are the primary explanation for the increase in the gap at higher percentiles. We then argue that government investment policies and the manipulation of price incentives were important factors behind the gap. In particular, we argue that government policies created some benefit to urban dwellers at the expense of rural …

Making Sustainable Creative/Cultural Space In Shanghai And Singapore, Lily Kong
Research Collection School of Social Sciences
Shanghai and Singapore are two economically vibrant Asian cities that have recently adopted creative/cultural economy strategies. In this article I examine new spatial expressions of cultural and economic interests in the two cities: state-vaunted cultural edifices and organically evolved cultural spaces. I discuss the simultaneous precariousness and sustainability of these spaces, focusing on Shanghai's Grand Theatre and Moganshan Lu and on Singapore's Esplanade-Theatres by the Bay and Wessex Estate. Their cultural sustainability is understood as their ability to support the development of indigenous content and local idioms in artistic work. Their social sustainability is examined in terms of the social …
Cultural Icons And Urban Development In Asia: Economic Imperative, National Identity, And Global City Status, Lily Kong
Research Collection School of Social Sciences
Global cities are characterized by the multiplicity of flows that they are implicated in - flows of people, goods, services, ideas, and images. Yet, global cities do not derive their status only on the basis that they are networked nodes. They also require particular forms of cultural capital. Cities with global aspirations have thus increasingly recognized the need to accumulate cultural capital, for which one means is to create new urban spaces, in particular, new cultural urban spaces (e.g. grand theatres, museums, libraries). These often monumental structures are intended to support a vibrant cultural life, in order to attract and …
