title: Reducing the residual power supply of Singapore with solar PV in combination with energy storage

description: Using Singapore's solar potential to produce electricity could increase its energy independence and reduce the specific CO2 emissions of its power supply. Thereby, energy storage technologies offer the opportunity to increase the usage of electricity from solar PV during power demand peaks. This would lead to more efficient power plant use and less required residual generation capacity. In this paper we analyse the power generation capacity that can be replaced by solar PV in combination with energy storage. In our research, we use a linear programming model of Singapore's power supply that optimizes power generation and storage according to minimal total cost. To determine the power generation by solar PV we use direct measurements of solar irradiation in Singapore. Results show that generation capacity can be replaced by solar PV most efficiently with lower storage sizes and lower solar PV capacity installed. By installing 5 GW of solar PV installed and a storage capacity of 1000 MWh, up to 750 MW of generation capacity could be replaced.

title: Residential loads management by considering households' satisfactory levels for smart meter applications

description: In order to aim the target of using green energy resources in many countries, not only are energy harvesting technologies installed but demand side energy management has to be also implemented. With the fact that different person has different lifestyle; therefore, in this paper, satisfactory factor from households will be considered in residential loads management procedure. Loads will be shifted in order to avoid peak time period to off peak time while keeping the highest satisfactory score of users. The results show that after applying the procedure to 30 households in Tha Sala district, Nakhon Si Thammarat province, Thailand, overall price of electricity bills reduce at 2.17% with 95.6% satisfactory score by shifting only freely shiftable loads and the bills reduce at 6.22% with 87% satisfactory score by shifting all shiftable loads.  It affirms that the procedure can be developed to be the algorithm for smart meters which will encourage households to attend the demand side management program as each household which has different lifestyles will be treated in their ways instead of using identical smart meter for all households having different ways of living.

title: Energy consumption and GHG emission of Thailand's residential sector

description: In this study, historical energy data from various sources were compiled to evaluate the energy consumption in residential sector in Thailand. The energy consumption was characterized for houses located within and outside municipality and for different activities in the houses: lighting, cooking, entertainment, amenity and other.  Under the business-as-usual (BAU) scenario, the electrical energy consumption in the sector will increase from 48,611 GWh in 2010 (base year) to 100,475 GWh in 2030 and the greenhouse gas (GHG) emission will increase from 13,368 to 30,330 kTon carbon CO2.  However, under the energy efficient scenario, it was found that the GHG emission can be limited at 15,353 kTon carbon CO2 in 2030. The GHG emission reduction from power generation also plays an important role in the emission mitigation from the residential sector.

title: The effects of improved built form on urban cooling: review of passive strategies and urban design case studies

description: With the current rapid pace of construction in South East and East Asia, built form and blocks are changing significantly, having impact on the building physics and environmental performance of macro [urban] environments. Such change at macro scale has major impact on how spaces and blocks are shaped and developed. This has direct impacts on urban ventilation systems (both passive and active) and the built form or physics of the urban environments, including but not limited to, orientation, layout, massing and form. The paper reviews the various opportunities for macro cooling via improved built form for urban residential environments and will further explore possibilities of urban cooling for the context of Asia. This paper specifically includes tropical and the warming sub-tropical areas of Asia.

title: LOAD-CARRYING CAPACITIES OF SYSTEM SCAFFOLD STRUCTURES WITH DIFFERENT TYPES OF BRACING

description: This research focuses on the loading capacity of scaffolds with different types of bracing. The scaffolds without bracing and with four kinds of bracing were included in the test program. The material test and member test were first conducted in this study to obtain the material properties and the connection parameters for comparison. It was observed that the ultimate tested loads of specimens with bracing are much greater than those of the specimens without. Discussion turned to ultimate load, critical buckling load, and failure mode for all specimens based on the test results. In addition, software SAP2000 was used to predict scaffold strength. It was found that the discrepancy between ultimate strengths for scaffolds with and without bracings is limited because only vertical loads were applied to specimens. The predictions of ultimate strength became different for the scaffolds with and without bracings as long as the notional horizontal forces, which were used to simulate the initial imperfection, were applied on the scaffolds. Despite the expectation that the four bracing types would yield distinguishable results, the SAP2000-computed ultimate strengths for the bracings were quite similar. Therefore, a more realistic model was adopted to investigate the strength by including effects due to both 2nd-order geometric and simple material nonlinearity.

title: RETROFIT STEEL CORRODING RC BEAMS USING CFRP COMPOSITES: NLFE ANALYSIS

description: Corrosion of steel reinforcement is one of the main durability problems facing reinforced concrete infrastructures worldwide. Steel degradation and/or cracking of concrete both cause severe reduction in bearing capacity, leading ultimately to failure. The potential of repairing corroded concrete beams with two configurations of carbon-fiber reinforced polymeric (CFRP) composites was investigated with a nonlinear finite Element (NLFE) model. CFRP composites were assumed to be either bonded directly to existing concrete or to a new concrete cover; replacing the old one. The data generated showed that the load-bearing capacity and stiffness for concrete beams, as long as corrosion levels were below 10%, can be fully restored. However, the ductility in terms of deflection at failure would be reduced, especially for repair techniques that involved anchoring with CFRP sheets. For corrosion levels greater than 10%, attaching CFRP composites to a new concrete cover contributed to additional improvements in load capacity and stiffness ranging from 10 to 15% of that achieved from similar repairing on existing concrete. The failure modes indicated that debonding failure prevailed, and that the extent of debonding prior to failure depended upon the corrosion level and on whether the concrete cover was replaced or not.

title: Evaluation of greenhouse gas emission from residential buildings in Thailand

description: Apart from energy sector, greenhouse gas (GHG) emission from the construction industry has become more significant especially indirect GHGs from carbon embedded in construction materials. This paper presents the evaluation of GHGs from construction materials in different residential buildings such as detached houses with different styles (contemporary, modern and Thai modern houses) and low-rise and high-rise condominiums in Bangkok. The concept of carbon footprint was applied in this study to evaluate how much GHG emitted from construction process. The activity data were extracted from floor plans and Bill of Quantities (BOQ) of 42 houses and 12 condominiums. The GHG emissions in the unit of kgCO2 e/m2 were calculated in the scope of cradle to gate, following Thai national guideline for carbon footprint of product and Thai national life cycle inventory database (TGO, 2011). The high-rise condominium built from precast concrete emitted the highest GHGs (326.77 ? 22.01 kgCO2e/m2). While the Thai-modern house built from half wood-half concrete emitted the lowest GHGs (2.47 ? 36.37 kgCO2e/m2) due to the large carbon offset from wooden construction materials.

title: An application of resonant inverters for hysteresis-loop measurement

description: This paper presents an application of a resonant inverter for hysteresis loop measurement of a ferrite core. The series resonant inverter is used as a replacement of the commonly used linear power amplifier where the bias current level is limited. The proposed system is design to measure a hysteresis loop of a ferromagnetic material at high frequency. The maximum flux density (Bm) and maximum magnetic field intensity (Hm) of a ferrite core is obtained through variation of the input voltage and frequency. A comparison of the experimental results and the specifications from the manufacturer is provided.

title: Effects of refrigerant circuiting of fin-and-tube condenser on performances of an inverter air conditioner using ozone-friendly refrigerants as alternatives to R-22

description: This paper presents the investigation of the proper refrigerant circuiting in the finned tube condenser for an inverter air conditioner. The experimental study was carried out with four coil configurations using R-22, R-407C, R-417A, R-404A and R-507 under a variety of refrigerant flow conditions. The test results indicate that refrigerant path arrangement affects the performance of variable capacity system significantly. The efficiency of retrofitted system could be improved by using the inner-split configuration with R-417A for a wide range of frequency, although Z-type path and upstreamsplit configurations would give better performances at low and high ranges of frequency, respectively. The finned-U tube models were developed using tube-by-tube and segment-by-segment algorithms comparatively. The simplified model with tube-by-tube method can predict capacities with acceptable accuracy level.

title: Influence of thermal treatment on PtAu/C catalyst for glycerol electrooxidation in alkaline media

description: The Au-based catalysts were prepared by using polyvinyl alcohol protected method. The physical and electrochemical properties of the as-prepared catalysts were measured. The catalytic activity and stability of the PtAu/C catalysts toward glycerol electrooxidation were measured using cyclic voltammetric and chronoamperometric methods. To promote the alloy formation between Au and Pt, heat treatment of the catalyst was performed with PtAu/C in a temperature range of 300-700?C at a heating rate of 10?C/min of under nitrogen atmosphere. The alloying degree of the heat-treated catalyst increased with increasing heat treatment temperature. Consequently, the significant enhancement of the onset potential of glycerol oxidation was achieved for the catalyst treated at 700?C. Moreover, The H-300 PtAu/C catalyst exhibited the lowest decay rate. However, the heat treatment also promoted sintering phenomenon of the metal particles leading to the decrease of the maximum current density. Therefore, the untreated PtAu/C showed higher performance than the heat-treated one.

title: Glass Ceramics Seals for Solid Oxide Fuel Cells

description: In this paper, several silicate glass ceramics with thermal expansion coefficients ranging from about 5 x10-6 to 12x10-6/oC have been assessed as sealing for SOFCs.  Glass ceramics with thermal expansions close to YSZ and GDC10 solid oxide electrolytes were selected for electrical property measurement and development of hermetic seals.  Small addition of zirconia up to 0.4 mole % to barium calcium alumina borosilicate glass compositions confers beneficial effect to the development of hermetic seals without covering the surface of the fuel cell element. This has enabled the power density of single fuel cell elements to be evaluated. The thermal expansion and the insulating behaviour of the sealing materials in moist oxidising and reducing environments are presented and discussed in relation to the microstructures evolved.

title: DEVELOPMENT OF A SEISMIC FITTING FOR WOODEN BUILDINGS

description: Japanese wooden buildings are vulnerable to large earthquakes, and ensuring their seismic safety is a significant issue. However, many owners of wooden buildings hesitate to install seismic reinforcement because of the long construction period and high expense. There are many sliding doors in wooden buildings, which can be used for efficient seismic reinforcement. The objective of this study is to develop a seismic fitting for Japanese wooden buildings. Full-scale lateral loading tests were conducted for wooden frames that include a seismic fitting. The fittings can be constructed quickly and at a low cost. The parameters of the full-scale lateral loading tests were chosen in order to examine the effect of the fitting and the restriction condition surrounding a fitting on the seismic performance of a wooden frame. The relationships between the lateral load and deformation angle, the collapse mechanism, and the quantitative effect of seismic reinforcement for a wooden frame were clarified. From the results of the full-scale tests, it is found that the lift up of a seismic fitting should be restricted by a hanging wall for the seismic reinforcement of wooden frames.

title: AN EXPERIMENTAL STUDY ON THE LOAD CAPACITY OF STEEL SCAFFOLDS WITH LINED SETUPS

description: Due to high clearances and large spans, some areas of reinforced concrete buildings, such as the entrance lobby of a hospital or the stage area of an auditorium, often need to design large-scale isolated reinforced concrete beams to support the weights from slabs and beams. On construction sites, the falsework of single-line steel scaffolds is often set up underneath these isolated beams based on the lined setup. Since the setup of these steel scaffolds is unique and data available for designing are lacking, single-line steel scaffolds are often installed on construction sites based on workers? experience. Study results show that the load capacities of one-bay, two-story door-type steel scaffolds (2D) are similar to those of one-bay, three-story door-type steel scaffolds (3D). When adopting multi-bay setups, the load capacities of two-story door-type steel scaffolds (2D) and of one-door, one-square, two-rectangle steel scaffolds (DS2R) increase with the number of bays. Although the height of the DS2R setup is higher than that of the 2D setup, the load capacity of the DS2R setup is still higher than that of the 2D setup, indicating that the strength of the combined setup of steel scaffolds is higher than that of pure door-type steel scaffolds. By applying the second loading using reusable materials, to simulate the load capacity of the steel scaffolds under the worst conditions, this study obtained the strength reduction factors of the steel scaffolds using reusable materials.

title: Investigation of appropriate refrigerant circuiting of fin-and-tube evaporator in an inverter air conditioner using ozone-friendly refrigerants as alternatives to R-22

description: In this study, the effects of evaporator circuiting on the system performance of inverter air conditioner were investigated. Four evaporator configurations were tested using R-22, R-407C, R-417A, R-404A and R-507. The experimental results indicate that although the refrigerant circuiting is almost arranged properly with counter-cross flow configuration, however, the performance of R-407C and R-417A coils could be improved by parallel-cross flow configuration. This result is somewhat smaller at a low range of frequency. The two-circuit coil gives the maximum improvement in COP with lowest frequency. The three-inlet two-outlet configuration using R-417A can be properly used as substitute for the conventional configuration with R-22 under a wider range of frequency. This work also developed the improved models using tube-by-tube and segment-by-segment algorithms that are applicable to evaporator with complex circuitry under a wide range of refrigerant flow rate. The tube-by-tube- method has been found to suitably predict the experimental results.

title: Trend of final energy intensity changes in Lao PDR

description: While being developed, Lao society and economy have gradually shifted from agricultural-based to service-industrial oriented one. As a result, final energy consumptions are also rapidly changing. The paper studied a trend of changes in final energy intensity by looking at sector-wide energy demand and contribution shares in Gross Domestic Products. It was found that intensity of total final energy consumption in Lao PDR gradually decreased during about the last decade, which was considered as a good trend. This was resulted of fast stable economic growth and comparatively slow growth in energy demand. Furthermore, Lao economy still relays mainly on less-energy intensive economic sectors, such as services and traditional agriculture. Although Energy intensity of the Industry, transportation and services sectors has decreasing trend, but slowed down in recent years. Moreover, energy intensity of agricultural sector has increasing trend. All these facts give a ground for thinking that in the future, when socio-economic development of the country will reach higher level, there will be more energy consuming activities, then energy demand will increase while economic growth will slow down, and therefore, energy intensity is to increase. Knowledge on trend of energy consumption changes would be useful for predicting energy demand and securing energy supply in the future.

title: Ray tracing method for simulating daylight transmission through tubular light pipes with anidolic concentrator

description: Light pipes can bring both daylight from the sun and daylight from the sky into deep interior spaces of a building. However, light pipes are still considered costly. Adding an anidolic concentrator at the entry port of a light pipe will increase daylight capture and may reduce the overall cost per unit of delivered daylight flux, especially for long pipes or pipes with bends. This paper presents results of modeling, and simulation of transmission of beam daylight through tubular light pipes.  Analytic method is used for tracing light rays from the sun and sources in the sky zones through the anidolic concentrator to the straight sections of a pipe through to the exit port. The vertical curvature surface of the anidolic concentrator is modelled as a parabolic section. The algorithms are coded in a MATLAB program. The results show that the concentration ratio of a concentrator is a function of its acceptance angle and the reflectance of its surface. The method can be used for analysis and design of such system.

title: Selective removal of organic sulfur in fuels

description: In a series of studies on precleaning technology based on sulfur forms, an advanced desulfurization process that can be carried out under mild conditions has been developed for the production of clean sulfur-free fuel. The selectivity of adsorption of various metal compounds to thiols, sulfides, and thiophenes in a model fuel at room temperature was investigated. Among the studies metal compounds, lead oxide showed the highest selectivity to aliphatic and aromatic thiols.  For the extraction of thiophenic sulfur selectively from the fuel, halogen-free ionic liquids with different alkyl chain lengths were prepared. The extraction yield of dibenzothiophene increased linearly with an increase in the length of alkyl chains and mass ratio of the ionic liquid to the model fuel.

title: CHARACTERIZATION OF GEOPOLYMERS OBTAINED BY ALKALINE ACTIVATION OF METAKAOLIN WITH HIGH IRON CONTENT

description: The use of activated alkali aluminosilicate has been shown to be an economically-viable alternative that decreases the environmental impact of building construction material. Geopolymers are a type of activated alkali aluminosilicate that are rich in SiO2 and Al2O3, and harden within alkaline solutions. In this study, geopolymers obtained by alkaline activation of metakaolin with high iron content were characterized. The activation process used sodium hydroxide solutions at molarities of 12, 15, and 18 mol. The geopolymers were oven-dried at 85ฟC and at room temperature. The results identified the physicochemical and microstructural properties of the geopolymers and elucidated the activation process using the techniques: XRF, XRD, DTA, TG, DTG and DSC analysis. The results of the dynamic recrystallization indicated the presence of quartz, kaolinite, hematite, and muscovite in the samples. The DSC analyses showed an immediate reaction between the precursor material and the activator. The DTA results showed that the reactions began at low temperatures, where the dissolution of Si and Al occurred. The peaks that appear between 45ฟC and 60ฟC indicate that polymerization occurred through the condensation of Si and Al.
