title: Does gender influence energy efficient decisions in low-income households in GMS countries?

description: This paper studies influence of gender in energy efficient decisions in low-income households through a household questionnaire survey analysis. The study focuses on a particular consumer group, Modern Energy CONsumers (MECON), defined as those who has access to electricity but still poor with an income range of 2-5$/person/day in the Greater Mekong Sub-region (GMS) countries, namely Cambodia, Myanmar, Laos, Thailand and Vietnam. The diversity of social structures, culture and policy regimes across GMS countries may have some gender influence in household energy decisions. Understanding influence of gender in household's energy decision will help designing strategies, targeting a particular gender, to increase uptake of energy efficient appliances in low-income households. The analysis show that in three of the four countries analyzed in this paper, those households where man takes energy decision have relatively high share of CFL lamps than that of the households where woman takes energy decisions. Analysis further shows that it was mostly men who has seen an energy label before. In contrast, analysis shows that energy labels influence mostly women in their energy decisions than that of men.

title: Daylighting through external vertical slats on east windowed fa?ade in a tropical climate

description: In the tropics, daylighting from a side window requires shading to intercept direct sunlight from the window whilst allowing penetration of daylight from sky. In this paper, daylighting from external vertical slats was investigated for which they are equipped on east-facing window of a room.  Full-scale experiments and simulations were conducted to characterize distribution of the interior daylight from the slat window under a real tropical climate. Performance of the slat window was evaluated in terms of the "Useful daylight illuminance" (UDI), interior daylight availability and light power density (LPD) of an integrated dimmable lighting system.  Using our tropical records of daylight illuminance, the simulation results show that altering properly the tilted angle of the vertical slats with the same configuration as that of the experimental room can improve the interior daylight illuminance and distribution and can save about 75% of electric energy from dimmable lighting.

title: New modern energy consumers in the Greater Mekong subregion

description: This study aims to examine a particular income group of energy consumer in the Greater Mekong Sub-region (GMS), which includes Cambodia, Lao PDR, Myanmar, Thailand, and Vietnam. This income group, referred as MECON, is defined as those who are those who connect to electricity grid with daily income of $2-5 (2005 PPP). This target group is important for the future energy demand in this region as they are likely to earn higher incomes, own more household appliances, and consume more energy in the near future. This paper discusses on the definition of MECON, and its application. The study, then, uses the method reviewed from literatures, and PovcalNet, World Bank's poverty analysis tool to test if the income range is usable to capture the target group.  The result shows the percentage headcount of MECON to national populations in this region, and its trend. The finding suggests that this target group tends to decline in Thailand which is opposite to other GMS countries. Also, MECON group will become more important to residential energy consumption in this region in the future.

title: Availability and market barriers to energy efficient technologies for household in Cambodia

description: The 2012 World Energy Outlook highlights the importance of energy efficiency (EE) in reducing greenhouse gas emissions in the coming decades. The objective of this study is to explore the available energy efficient technologies for using in households, with a focus on low income households and to assess market barriers to EE products. The study is conducted with household appliance retail shops in Phnom Penh City and Siem Reap province. The information on availability and market barriers to EE products is collected using questionnaire. 100 retailers in Phnom Penh City and 65 retailers in Siem Reap province are randomly selected for face to face interviews. Results of the study show that EE products for households are available in market in Cambodia with more than 80% of sampled retail shops selling EE products such as air conditioner, refrigerator, washing machine, iron, water boiler and water pumping The study also indicates that the key barrier indicated by retain shop is that customers don't care about environment, they care about the price of EE technology. Other key barriers are that customers and shop staff are lack of awareness and the information on EE products. Regarding to policy barrier, financial incentives to EE products and environmental policies and regulations are also key barrier.

title: Energy efficiency indicators comparison in Thailand, OECD and EU 28 countries

description: Some energy efficiency indicators for Thailand and OECD and EU 28 countries are analyzed in the period from 1990 to 2012. Both Thailand and mentioned regions have enacted and implement energy policies which have many common elements and which are by all means devoted to the increase of energy efficiency and wider use of renewable energy sources for the purpose of reducing GHG emissions and to achieve sustainable development. However, the results of the implementation of these policies are very different and point out to the great influence of economic, social and political factors. Energy efficiency depends on numerous mutually independent factors but the greatest problem is in the fact that most important factors cannot be affected by individual countries. This leads to the need to constantly control the implementation of the energy efficiency policy and to make adjustments to it. Very often, these changes are imposed by rough effects of external factors which are the consequence of globalization and the pressure of those who enforce this globalization. This paper offers some answers to possible reasons for the deviation of values and trends of energy indicators in the most developed regions in relation to Thailand.

title: THE IMPACT OF CLIMATE PARAMETERS ON THE SURFACE OF BUILDINGS? WALLS

description: The durability of surface layers of enclosures (outside walls of buildings) is highly influenced by stresses occurring in the plane of contact between finishing materials and that of the enclosure. Damage to external walls depends on a high moisture content, which in turn depends on high water absorption during driving rains. One example of such damage is damage due to direct water penetration in homogeneous walls. The other negative effects of a high moisture content are impaired heat insulation and accelerated degradation. This article investigates the external layer of walls and the durability of different paints. In case of bi-laminar system ?paint film - the wall being painted? two opposite processes take place: the water flow rate from the outside towards the wall, and the water vapor flow rate of the wall to the outside. The optimum selection of paint is necessary. An investigation of the durability of wall surface paints in a climatic chamber is instructive only after intermediate investigations and measurements of the substrates? physical and mechanical properties that aid in predetermining durability. The influence of moisture deformations upon degradation of coatings depends on the porosity of surface materials being coated, and on the origin and macrostructure of the coating.

title: Optimization of hydrogen production from a sorption-enhanced steam reforming process

description: The sorption-enhanced steam reforming is considered to be a suitable process for hydrogen production. By adding solid calcium oxide (CaO) to a reformer, carbon dioxide (CO2) is removed via a carbonation reaction and the yield of hydrogen is improved. The aim of this study is to find the optimal operating conditions of the sorption-enhanced steam reforming process using methanol as a hydrogen source. The fixed-bed reactor model in flowsheet simulator is applied to explain the sorption-enhanced steam reforming based on the kinetics of methanol steam reforming, methanol decomposition, water gas shift reaction and carbonation reaction. The sensitivity analyses of primary parameters of the sorptionenhanced steam reformer were performed and the obtained results were used for the optimization task with the aim to find its optimal operating conditions to maximize hydrogen yield with the presence of CO in the hydrogen product below 10 ppm. It was founded that the sorption-enhanced steam reformer should be run at the temperature of 347?C and steam-to-carbon feed ratio of 1.78. The maximum hydrogen yield of 3 mole hydrogen per mole methanol used is achieved and the CO content in the hydrogen product is less than 10 ppm. However, the net heat input required for the sorption-enhanced steam reforming process is about 52% higher than a conventional steam reforming process due to the combustion unit for CaO regeneration.

title: CONSTRUCTION DEFECTS IN RESIDENTIAL BUILDING PROJECTS: PILOT STUDY

description: A vast number of studies about construction defects have been published in different countries, confirming that construction defects are a global issue. This problem often adversely affects the budgets, timing, and quality of construction projects. The lack of understanding about which construction tasks are prone to defects make implementation more uncertain and increases the chances of defects. This study seeks to identify and understand the behavior and pattern of task actions that are more prone to defects through the anatomy process of a specific task. The first objective in this study was to identify, track, and record construction defects during the execution of a number of actions within a specified task. The second objective was quantifying which actions are more prone to construction defects and determining the reasons why. Fifteen case studies were conducted on residential buildings, which included 45 items focusing on the column sub-task. Initial results suggest that some actions within specific sub-tasks are more susceptible to defects. This research aims to improve the understanding of construction defects and solutions, enhance cost controls, reduce time overruns, and improve execution quality.

title: PERMEABILITY OF TUNNEL LINING WITH AIR/WATER BUBBLES ON CONCRETE SURFACE

description: Air and water bubbles are likely to remain on concrete sidewalls in tunnel linings, because the sidewalls are generally constructed with a greater slope than a right angle. The bubbles negatively influence the aesthetic of the concrete lining. In addition, concrete with a lot of large bubbles may decrease durability, such as air permeability. Although most tunnel lining is constructed as plain concrete without reinforcement, the low permeability may affect the maintenance and long-term durability of the tunnel. The study aims to examine the effect of bubble distributions on the permeability of concrete lining. Concrete specimens including various bubble distributions are prepared by using variable angle-forms in a laboratory test. Furthermore, the bubble distribution (area ratio) and the permeability are examined in two actual tunnels. This paper presents a relationship between bubble distribution and air permeability based on these tests. The results show that the relationship is a logarithmic curve of the bubble rate and gas permeability.

title: SEGMENT CRACKS AND ALIGNMENT ISSUES FOR TUNNELING CONSTRUCTION

description: This study describes the causes of shield tunnel segment cracks and alignment issues during shield tunnelling. The study was conducted in Down Town Line 3 (DTL3) contracts 926 and 927 twin tunnel projects in Singapore. It is revealed that these issues arose when Tunnel Boring Machine (TBM) shoving on curve alignment though TBM is designed with articulation, which allows the machines to handle tight curves with ease. The study focused on how construction methodology affects the quality of tunnelling in terms of alignment and segment cracks. It was found that the clearance between the tail shield and tunnel lining was not maintained during mining. As a result, the tail shield exerts stress on the segments and causes cracks. In addition, the tunnel alignment deviated from pre-designed alignment, which directly affects the safety and durability of the shield tunnel. This study concludes that a proper selection of ring type ?right lead? or ?left lead? and the appropriate key selection, along with the skill of the workers, significantly solve segment cracks and alignment issues.

title: SODIUM SILICATE ACTIVATED SLAG-FLY ASH CEMENT

description: This research examines an alternative binder, Alkali Activated Cement (AAC), examining the fresh and hardened mechanical properties of twelve AAC mortar mixes with varying mixture proportions of blast-furnace slag, fly ash, sodium silicate (the alkali activator), and additional water. In addition to the Slag-Fly Ash mortars, nine mixtures with blast-furnace slag, silica fume, aluminum hydrate, sodium silicate, and water were tested. For all mortars, the compressive strength was exponentially related to the water/activator-solids ratio. Mortar strengths at 28 days ranged from 5 MPa to 20 MPa. Increasing the slag to binder-solids ratio from 0.1 to 0.2 increased the strength with water to binder ratios from 0.2 to 0.4. However, rapid or almost instantaneous setting times were observed for a slag to binder-solids ratio of 0.2. The research concluded that using a carefully chosen mix design can prevent quick setting while still achieving high strength and acceptable workability. It is suggested the CaO to binder-solids ratio remain below 0.07; a sodium silicate to binder solids ratio of around 0.25 is optimal; a water to binder-solids ratio should be around 0.3. When replacing fly ash, a Si/Al ratio above 2 is recommended. This research concluded that other solids (Silica Fume and Aluminum Hydrate) could replace Slag and/or Fly Ash if the overall chemical balance of the system is maintained.

title: A tool for Thailand's green industry enhancement: case study on sustainability indicators at national level for mining industry

description: According to concept of sustainable development, the mining activities should be done to maximize the needs of current generation by supplying equitable distribution without decreasing the ability for future generations to achieve their own needs. In addition, adopting Green Industry concept is considered to be one alternative to strengthen the sustainability of mining industry in Thailand.  However, to achieve that goal, the impact assessment tools for mining industries at national level in Thailand should be promoted. Hence, this study aims to provide a tool for sustainability indicators and link them with corporation among diverse stakeholders in the future. The sustainability indicators were grouped into 3 categories regarding key elements of sustainable development.  For the linkage between indicator and corporation, the directions are divided into 2 major aspects by key elements and group of stakeholders. The results show that both indicator development and cooperation among organization should be commonly promoted to execute sustainable development in mining industry.

title: Comparison of short term and long term SOC stock change in rice field rotated with energy crop

description: This study focused on investigation of soil organic carbon change in short term and long term from abandoned rice field reclaimed by energy crop rotated with rice. The field experiment was designed in abandoned rice field from Aug 2009 to Jan 2013 at King Mongkut's University of Technology Thonburi, Ratchaburi campus, Thailand. The four crop rotation systems designed to fallow land- rice (RF), rice-rice (RR), corn-rice (RC), and sweet sorghum-rice (RS). The SOC stock at 0-15 cm of soil depth was estimated by equivalent soil mass method (ESM). The site mode of DNDC model (version 9.3) used to estimate the long term SOC stock change. In short term of field experiment, the SOC stocks changed from the initial soil through the land use change, tillage and crop rotation practices. The SOC stock from 1st to 2nd crop in RR was significant 33% increasing and from 2nd to 3rd crop in RF, RC and RS was significant increased 38%, 37% and 42%, respectively. Long term simulation, SOC stock in RR, RC and RS was higher 42%, 33% and 25% than fallow-rice crop system, respectively. The energy crop rotation in rice field able to maintain soil carbon storage in long term.

title: Fire Behavior at Kuan-Kreng Peat Forest, Nakorn Sri Thammarat Province

description: Kuan-Kreng swamp forest located in southern Thailand and covers an area of 24,000 ha. About 2,100 ha burned in 2012. These fires lead to the changes in ecosystem structures   and functions. Thus, fire management is very important. Unfortunately, peat fire information for Thailand has never been systematically investigated. This research aims to learn about forest fire and fuel characteristics in Kuan-Kreng swamp forest. Twelve plots of 30x30 m which consisted of  4 plots in lowland Malaleuca's stand, 4 plots in upland stand and 4 plots in open grassland. The average Pre-burn fuel load for lowland, upland and grassland sites were 11.96, 21.20 and 13.73 ton/ha, respectively. Undergrowth litter contain the highest heat value (4289.19 ca/ g), while heat content of peat soil was lowest (3280.73 cal/g). All of fire behavior descriptors were highest in grassland and lowest in lowland, ROS in grassland was highest, though there were non-significant differences. FH and FL were significant highest in grassland. However, FH and FL were not significantly difference between Malaleuca sites. FI in this study was highest in grassland (720.6 kW m-1), and it was lowest in lowland site (87.5 kW m-1). However, FI varied from plot to plot, resulting in non-significant differences between sites.

title: IMPACTS OF PRE-STRESS LOSS ON THELONG-TERM DEFLECTION FOR LONG-SPAN PC CONTINUOUS GIRDER BRIDGE

description: In order to analyze the impacts of pre-stress loss on the long-term deflection for long-span PC continuous girder bridges, this paper presents a numerical analysis using the finite element analysis software MIDAS/Civil based on a long-span PC continuous box-section girder bridge in Shijiazhuang. Once the 3-D finite element model was established, the influences of different pre-stress loss levels and locations were analyzed in a numerical simulation. Pre-stress loss is often the key reason for long-term deflection in long-span PC continuous girder bridges, so we can estimate the development of deflection by considering these factors during the operation.

title: A STUDY OF GROUTING MATERIAL BLEEDING PROPERTIES FOR PRESTRESSED CONCRETE

description: This study investigates the workability, bleeding, and volumetric change of grout widely used in Korea for securing the quality of grout applied in prestressed concrete (PC) bridges. The results reveal that the workability satisfies all the criteria for the grout specified in Korea. It appears that bleeding increases by 5.7 to 6.7 times when the tendon is arranged, regardless of the quality of grout, and that the height and inclination of the grout sample significantly affect bleeding. Furthermore, the arrangements of tendons were seen to prevent expansion even in grout using expansive aluminum powder, but was also seen to let shrinkage occur with a significant increase in bleeding. The conclusion is that it is necessary to establish a new testing method and apply high-performance grout for securing the quality of the grout used in PC bridges.
