Thailand's Future Green Energy for Sustainable Urban Development
- Authors: Pawinee Iamtrakul, Suapphong Kritsanawonghong
  Pages: 7 - 18
  Abstract: Due to energy efficiency action plan to reduce the energy intensity, the recommendation for utilization of renewable energy integration plays an important role among several choices of renewable energy, especially solar, biomass and wind energy and development the cogeneration system. However, different available sources of distributed energy resources both combined heat and power (CHP) system or renewable energy system have its own potential of implementation through urban development. Thus, this paper reviewed the situation and demonstrated the potential of the implementation of different energy options under constrains and limitations. Furthermore, environmental issues among local people were considered towards the implementation process under public resistance along with rules and regulations in obtaining permission and trend of investment. As such, the finding could be strategically important to the sustainable development of the country with the possibility to allow private sector to participate in the generation business could be in order to promote the competition of power industry.

The Simulation of Cooling Effectiveness of Trees to Improve Outdoor
Thermal Environment on Different Climate-Sensitive Urban Forms During a
Summer of Bangkok
- Authors: Manat Srivanit, Kazunori Hokao
  Pages: 19 - 28
  Abstract: This study aim to delineate an urban planning metric for greenery called the green plot ratio (GPR), is based on a common biological parameter called the leaf area density (LAD), which is defined as the portion of the single-side leaf area per unit volume of tree canopy. The study will investigate the effectiveness of GRP for urban greenery to maximize cooling benefits and potentially improve the daytime heat effect. Four climate-sensitive areas for tree planting with different Bangkok’s urban morphologies are evaluated through an urban micro-climate simulation performed by the ENVI-met model. Simulation results indicated that the cooling effect of GPRs is highly associated with urban form. Maximum air temperature reduction (a 1.2 ◦C reduction at the pedestrian level) is the most profound for the very high-density urban form on summer diurnal range of tropical climate, whereas the average air temperature vary linearly is reduced during the peak heat of day by 0.02°C–0.12 °C by increasing GPRs. These findings will help urban planners offer better guidelines for planting and establishing urban trees to mitigate extreme heat in the hot-humid tropical environment.

Environment and Comfort of a Condominium in Bangkok
- Authors: Parinee Srisuwan, Shoichi Kojima
  Pages: 29 - 42
  Abstract: Urbanization, social change, and the development of housing for foreign expatriates coupled with the extension of a mass transit system, the condominium market in Bangkok have grown rapidly. It has led to an increase in energy consumption in the residential sector since an air conditioning system plays a vital role in maintaining indoor thermal comfort. In this study, the combination of passive design strategies with the active system was proposed regarding the field measurement and the simulation results using EnergyPlus version 8.4. An initial design modification, based on the three-tier design approaches to achieve sustainable building was carried out in order to improve indoor thermal comfort and reduce cooling energy consumption for a high-rise condominium unit in a hot-humid climate of Bangkok.

An Application of Importance-Performance Analysis (IPA) for Evaluating
City Bus Service Quality in Cambodia
- Authors: Sonita Sum, Thanapong Champahom, Vatanavongs Ratanavaraha, Sajjakaj Jomnonkwao
  Pages: 55 - 66
  Abstract: The purpose of this paper is to evaluate the service quality of city bus in Cambodia. In this research, Importance-Performance Analysis (IPA) was applied with the focus on assessing the city bus service quality from the users’ viewpoints. In order to evaluate the service quality, the twenty-four items were grouped into five different factors concerning Bus Services, Bus Stop Facilities, Driver Attitude, Vehicle, and Bus Capacity with the use of five-point Likert scale. On a five-point Likert scale, face to face survey was performed to grasp the users’ expectations and perceptions on the service quality, resulting from 500 respondents. The IPA, a strategic tool, is composed of four quadrants namely: (1) Concentrate Here; (2) Keep up the Good Work; (3) Low Priority: and (4) Possible Overkill, resulting to identify the attributes of service which need to be improved immediately and the ones which are not essential currently, the ones which are overestimated, and the criterions that are satisfactory. Finally, the graphical results play a critical role for the government authorities/agencies to find out the focus areas for an improvement of city bus service quality.

Takakura Composting Method (TCM) as An Appropriate Environmental
Technology for Urban Waste Management
- Authors: Fritz Akhmad Nuzir, Shiko Hayashi, Koji Takakura
  Pages: 67 - 82
  Abstract: The term of "Appropriate Technology (AT)", introduced by Schumacher which refers to all kind of technologies including environmental technology, has been since developed into a global discourse on technology advancement and its impacts of implemThe term of "Appropriate Technology (AT)", introduced by Schumacher which refers to all kind of technologies including environmental technology, has been since developed into a global discourse on technology advancement and its impacts of implementation on human civilisation as seen from various perspectives. The technology could also relate to the basic, fundamental yet innovative technology. Using this perpective, Takakura Composting Method (TCM) always prioritise to be integrated with the local context to have more efficient and effective implementation of its method. This study aims to understand the implementation of TCM on the case study in Hai Phong, Viet Nam, which is a sister city of Kitakyushu which would provide an important base for formulation of a development model for further appropriate and sustainable implementation. This study firstly examined relevant references and extracted the most important socio-economic and cultural key-factors of AT such as: financial mechanisms and cost affordability; technological adaptability and independence; social and cultural acceptability; local needs, demands, and resources; community participation and involvement; commitment from local government; environment consciousness; and continuity and long-term impact. This was followed by a descriptive analysis based each key-factor within the on-going implementation of TCM in Hai Phong. Finally authors concluded that TCM mainly reflects all key factors within its implementation. However, the absence of proper waste separation and compost users, and the issue of how to use the existing facility appropriately in order to optimise the production are the main challenges for self-dependance and the continuity of TCM development in Hai Phong.entation on human civilisation as seen from various perspectives.

The New Urban Crisis – A Review
- Authors: Federico Puggioni
  Pages: 97 - 101
  Abstract: Many socio-economical shifts occurred after 2002, year of the publication of Richard Florida’s “The Flight of the Creative Class”: crucial years that shaped the actual geo-political balance and the global economy. While, in the full 9/11 and dot-com’s crash aftermaths, Florida’s topics have been seen as beacons from scholars, economists, and tech-enthusiast, and an enlighten part of the society saw in his words a road towards a brighter future, the turbo-capitalism increased its wealth, spreading around inequalities and contradictions that leaded the Western world to the dramatic 2008’s financial crisis. What consequences all these events had on the urban scenario, today' Was the creative class a part of it, and in which way' Fifteen year after, with another best-seller, Florida tries to answer these unsolved questions, giving new keys (and a new toolbox) to read, identify, understand and solve a (so called) “New Urban Crisis”.

Nakhon-Nayok Province, Thailand
- Authors: Pongpun Juntakut, Yaowaret Jantakat
  Pages: 83 - 96
  Abstract: Abstract Groundwater has become an essential resource over the past few decades due to climate change, which highly increases the demand for using freshwater. The groundwater quantity and quality are then a significant criterion in matching water demand and supply. The objective of the study is to integrate the application of Geographic Information System (GIS) and Program R with the Water Quality Index (WQI) for the evaluation of groundwater quantity and quality in Nakhon-Nayok province, Thailand. The result of the study shows that the most community in western study area (Amphoe Ban Na) has WQI on average and below average levels. As a result, the urbanization can clearly impact on groundwater quantity and quality in the study area. Appropriate methods for monitoring and improving groundwater quantity and quality in affected areas should be suggested, especially in urban areas. In addition, this study indicates that the application of GIS and Program R with the WQI can be an effective tool and help more efficiently for groundwater management.
