Urban policies and sustainable energy management


ABSTRACT: This paper describes the results of the first year of the SoURCE Sustainable Urban Cells research project. The projects main objective, focused on sustainable management of urban areas from an interdisciplinary and holistic approach, is to experience the sustainable reshaping of the city considering a minimum core of the larger citys model, conventionally called the urban cell. The methodological approach aims to evaluate and improve the energy flows from nature to city, from city to itself and from city to nature. The method seeks to provide a standard procedure to evaluate the performance and optimization of the urban cell energy balance through innovation technology either with the use of renewable resources or in the final consumptions. The methodology was tested in a case study of a single urban cell. Since any urban cell will have a different energy balance due to local characteristics and functions, an urban cell can be added to a close one (generating a urban cells grid) in order to ensure a better energy balance from the addition of more than one urban cell. The project foresees the elaboration of tools and strategies for citizen information, training them about energy sustainability, with special emphasis on young people.

COMMENT: This research belongs to a project named Source which is aim to get better sustainable management in Italy and Sweden. The writers introduce a method based on a minimum core called “urban cell” of the city to calculate and assess the balance between potential use of renewable energy source and energy consumptions. The writers also take it into a case study and get some results and conclusions. In my opinion, the method can be optimized for the simulation of energy use, because it provides a possibility to calculate the Ep and Ec. The models of urban area are currently idealized, so this method can be well fit for energy simulation of urban areas. As a primary idea, I will try to take it into practical use and get data which may be valuable for my research. It’s may be an easy way to get something that I want to analysis.

タイトル:商業床面積からみた都市活動に関する研究:大阪市メッシュデータによる分析
日本建築学会近畿支部研究報告集. 計画系 (43), 481-484, 2003-05-26

概要:
この論文では土地利用の変化を調べるために、商業延べ床面積の推移を分析している。具体的には、1969,1985,1993,2001年の店舗延べ床面積メッシュデータを考察している。そして、1993年から2001年の店舗延べ床面積増加率をY軸に1985年から1993年の増加率をX軸にとり、散布図を描き、Y軸・X軸それぞれにおいて2割以上の増加・減少を境界線とする9つのグループに分けることで、メッシュごとの類型化を行っている。

感想:
卒業研究で、商業延べ床面積を比較することで土地利用の変容を捉えようとしているので、この研究は参考になることが多かったです。今後の研究活動に活かせればいいと思っています。

Why retailers cluster: an agent model of location choice on supply chains
Environment and Planning B: Planning and Design 2011, volume 38, pages 82-94
Arthur Huang, David Levinson
http://nexus.umn.edu/papers/RetailPaper.pdf


Abstract:
This paper investigates the emergence of retail clusters on supply chains comprised of suppliers, retailers, and consumers. An agent-based model is employed to study retail location choice in a market of homogeneous goods and a market of complementary goods. On a circle comprised of discrete locales, retailers play a noncooperative game by choosing locales to maximize profits which are impacted by their distance to consumers and to suppliers. Our findings disclose that in a market of homogeneous products symmetric distributions of retail clusters arise out of competition between individual retailers; average cluster density and cluster size change dynamically as retailers enter the market. In a market of two complementary goods, multiple equilibria of retail distributions are found to be common; a single cluster of retailers has the highest probability to emerge. Overall, our results show that retail clusters emerge from the balance between retailers' proximity to their customers, their competitors, their complements, and their suppliers.

タイトル:企業誘致型地域経済振興策の勘所
http://ci.nii.ac.jp/naid/110007554251

概要:
この論文では、混迷きわまる日本経済において地域の産業振興策の課題について論じています。そして、企業誘致における鉄則として、資金面でのサポートと広大な土地の必要性を示しています。具体例として、九州と東北の自動車産業を取り上げていますが、失敗例として三重県の例を取り上げ、企業の転出防止には継続した魅力づくりへの努力が必要であるとしています。

感想:
自分の研究では、企業誘致のプロセスが関係してくるので、企業誘致の鉄則や誘致後の取り組みの必要性が分かり、非常に有益な論文でした。今後の研究に活かしていきたいと思います。

Agent-based modeling of the diffusion of environmental innovations — An empirical approach 
Technological Forecasting & Social Change 76 (2009) 497–511

Nina Schwarz, Andreas Ernst

In this paper, an agent-based model was developed to simulate the acceptance of 3 categories of water-use related technologies for domestic households in Southern Germany. Based on empirical survey and the concept of Sinus-Milieus, they divided agents to 5 lifestyle group, and then give the agents different behaviors and decision making principles based on their lifestyle. 

The result shows that water-saving innovations are likely to diffuse further in Southern Germany, and the information campaigns have a large influence on the diffusion of water-saving innovations.

Study on Development and Application of MAS for Impact Analysis of Large-scale Shopping Center Development
Journal of the City Planning Institute of Japan No. 41-3, October, 2006

http://webserv.ce.t.kanazawa-u.ac.jp/kawakami/UPL/ronnbunn/pdf/cpiy2006v41-3p271-276.pdf

The purpose of this study is to explore MAS to simulate the potential impact of city center generation.
In this paper, the policies specially refer to the development regulations concerning the location sites and upper limitation of large-scale shopping centers, which attract much attention of local government since their closing in city centers and shifting to out-of-center location are commonly recognized as one of the major reasons for the decline of city Centers. The MAS model is called Shopsim-MAS which is designed to simulate interactions between individuals that affected by the development regulations and to investigate their global effects on city centers’ commercial environment.
