title: Reducing the energy use and the carbon footprint of tropical housing

description: Following some decades of effort to reduce the energy embodied in, or consumed in, temperate housing, focus is now shifting to a similar effort for tropical housing. Energy reduction is a well-established strategy for reducing GHG emissions. A research consortium 'ELITH' of six-partners (of whom two are East Asian) has been funded by the UK government to investigate how the energy use, carbon footprint and cost of 'low-income' tropical housing might best be reduced. The research combines engineering, building science, architecture, town planning and physical modelling. Examples of programme research topics are (i) examination of the relationship between 'active' and 'passive' cooling under humid tropical conditions and (ii) how to reduce the energy embodied in walling. This paper focusses on the latter.

title: Political Persuasion and Attitude Change Study: The Los Angeles Longitudinal Field Experiments, 2013-2014

description: A randomized placebo-controlled trial assessed whether gay (n = 22) or straight (n = 19) messengers were effective at encouraging voters (n = 972) to support same-sex marriage and whether attitude change persisted and spread to others in voters’ social networks. The results, measured by an unrelated panel survey, show that both gay and straight canvassers produced large effects initially, but only gay canvassers’ effects persisted in 3-week, 6-week, and 9-month follow-ups. We also find strong evidence of within-household transmission of opinion change, but only in the wake of conversations with gay canvassers. Contact with gay canvassers further caused substantial change in the ratings of gay men and lesbians more generally. These large, persistent, and contagious effects were confirmed by a follow-up experiment. Contact with minorities coupled with discussion of issues pertinent to them is capable of producing a cascade of opinion change.

title: MECHANICAL PROPERTIES OF FLY ASH-BASED ALKALI-ACTIVATED CEMENT USING A STATISTICAL ANALYSIS TECHNIQUE

description: This paper presents the mechanical properties of fly ash-based alkali-activated cement (AAC). A statistical analysis method was used to determine the effect of mix proportion parameters on the dry density and compressive strength of fly ash-based AAC pastes and mortars. For that purpose, sample mixtures were designed according to Taguchi?s experimental design method, i.e., in a L9 orthogonal array. Four factors were selected: ?silica fume content? (SF), ?sand to solid ratio? (s/c), ?liquid to solid ratio? (l/s), and ?superplasticiser content? (SP). The experimental results were analysed by using signal to noise for quality control of each mixture, and analysis of variance (ANOVA) was used to determine the significant effect on the compressive strength of fly ash-based AAC. Furthermore, a regression-analysis method was used to predict the compressive strength according to the variation of the four factors. Results indicated that silica fume is the most influencing parameter on compressive strength, which could be decreased by superplasticiser and l/s ratio. There is no significant effect of sand-to-cementitious ratio on compressive strength of fly ash-based AAC. The dry density decreases as the sand-to-cementitious ratio is decreased. The increasing l/s ratio and superplasticiser dosage could further decrease the dry density of fly ash-based AAC.

title: DURABILITY OF BASALT FIBERS IN CONCRETE MEDIUM

description: This study investigates the durability of basalt fiber following immersion in a range of chemical solutions representative of the concrete medium. The tests were conducted over a 62-day period and the solutions were sodium hydroxide, sodium chloride, sodium sulfate and combinations of the three. Weight loss was observed in all alkali solutions, with the worst being the combination of sodium hydroxide with sodium sulfate. The impact of chloride was minimal in the alkaline environment and reduced the impact of the sulfate when both were present. Microstructure analysis using a Scanning Electron Microscope (SEM) found that the silica structure present in basalt fibers was degraded by the OH- from an alkaline medium. The study suggests the need for modification or treatment of basalt fibers before use as fiber reinforcement in concrete.

title: USE OF BIM TOOLS FOR SITE LAYOUTPLANNING

description: Building Information Model (BIM) has a wide range of applications and benefits that can help in communicating a large amount of information of the entire project lift cycle. BIM allows for 4D construction sequencing and scheduling through visual simulation. This paper demonstrates how BIM tools can be used for construction site layout planning and simulation. A methodology framework is developed to create the workflow necessary for the planning. Bentley's AECOsim Building Designer V8i was used as a modelling tool. Available on-line 3D models were sourced and collected for the simulation. In the process, shortcomings, or lack of BIM tools specific for Site Layout Planning, were identified. It is hoped that this research could lead to further development of BIM software aimed at supporting the construction industry.

title: Comfort assessment of radiant cooling in building in tropical climate

description: Radiant cooling is an alternative air-conditioning approach that has been successfully implemented in high latitude regions.  In the tropics, radiant cooling is quite challenge due to its cooling performance being limited by high-moisture ambient air.  This paper reports an investigation of radiant cooling in a tropical building.  The study comprises physical experiments of a radiant cooling system with cooling panels installed in a room of a laboratory building.  A dedicated outdoor air system using a fan coil unit was also installed to handle humidity of the room air through ventilation.  A TRNSYS software was used to model the systems in order to determine the thermal comfort level in the room using predicted mean vote (PMV) index.  The results show that the radiant cooling is able to use for air conditioning for human comfort in tropical buildings.

title: FLEXURAL PERFORMANCE OF RC BEAMS WITH NEAR SURFACE MOUNTED CFRP PLATE

description: This study investigates the flexural performance of RC beams strengthened with Near Surface Mounted CFRP plate. In construction, deterioration tends to occur due to changes in loading capacity, improper design, or poor quality of workmanship. This will result in long-term effects as the strength decreases over time. To prepare for the long-term effects, the Near Surface Mounted (NSM) method can be used to strengthen the RC members. This is to ensure that a structure can continuously function for its intended purpose. Three beams of 125 mm x 300 mm x 1800 mm (width; height; length) were constructed for this study. The first beam was not strengthened, the second beam was strengthened with a CFRP plate horizontally positioned on the tension zone, and the third beam was strengthened with a CFRP plate vertically positioned on the tension zone. All three beams were then tested under a four point bending test. Results show that the beam with horizontal strengthening was able to increase the flexural strength of about 22% compared to the control beam, while the beam with vertical strengthening was able to increase the flexural capacity of about 43% compared to the control beam. This indicates that the NSM method can be used to significantly increase the flexural strength of RC members.

title: Relationship between vegetation indices and gross primary production in dry dipterocarp forest, western Thailand

description: This study aims to investigate the relationship between the tower-based gross primary production (GPP) measurements and the satellite-based vegetation indices in dry dipterocarp forest). The study was carried out from September 2008 to March 2011. The results show that vegetation indices are strongly correlated to LAI and GPP.  These indices also captured well the temporal variations of GPP during the measurement period.  The coefficients of relationship between GPP and these indices were 0.88, 0.88, 0.85 and 0.88, for EVI, NDVI, MSAVI and SAVI, respectively. EVI has the strongest relation with GPP (y = 14.63x + 0.13, R? = 0.80) and therefore recommended as reliable proxy to derive the GPP for this forest.

title: Examination of carbon fiber production from the extracts produced from the solvent treatment of biomass

description: A production of carbon fiber by using a Soluble-based precursor, a low-molecular-weight compound extracted from a degradative solvent extraction process of rice straw, was examined in this study.  The procedure of carbon fiber production started from improvement of softening point of the Soluble, melt spinning, followed by stabilization and carbonization steps.  During spinning, three collecting speeds were varied; 600, 800 and 1000 rpm.  Based on 100 wt% of Soluble, it was found that the average yields of the spun fibers after experiencing stabilization step and carbonization step were around 69.7-70.0 wt% and 33.7-34.2 wt%, respectively.  The average diameters of the spun fibers were found to reduce with increasing spinning speed; 11.6, 11.0 and 9.6 ?m for the fibers spun at 600, 800 and 1000 rpm, respectively.  The tensile strength distributions of each spun fiber condition were shown to vary showing in the ranges of 578.2 MPa, 551.6 MPa and 626.3 MPa for the spinning speeds of 600, 800 and 1000 rpm, respectively.  These preprimary results were judged to show a good potential for the carbon fiber production from the Soluble extracted from rice straw.

title: THE INFLUENCE OF INITIAL MATERIALS ON THE COMPRESSIVE STRENGTH OF GEOPOLYMER SOILS

description: In recent years, geopolymers have received significant attention because they show environmental benefits, such as a reduction in the consumption of natural resources and a decrease in the net production of CO2. In addition, as green material, soil has low carbon dioxide production emissions compared to other building materials. In this research, soil was combined with activator alkaline to produce hardening materials as geopolymer soils. An alkaline solution with sodium hydroxide, sodium silicate and fly ash was used. The influence of clay content on the geopolymer soils? compressive strength was investigated. The best strengths were obtained from 5% to 12% clay content. SEM photos were also taken from specimens to investigate the structure of geopolymer soils. When combined with soil and fly ash in geopolymerization, fly ash reacted to the alkali solution quickly. The relationships between many variables such as clay content, fly ash, alkaline solution, curing time, and curing temperature were investigated by using a statistical analysis program with over 100 initial parameters. These results also indicate that the use of soils in geopolymer soil should have been limited. Additionally, increasing the sodium silicate in the alkaline liquid affected the geopolymerization reaction significantly. However, the suitable Si on the alkaline solution and soil should be limited.

title: DESIGN OF DOUBLE-SKINNED COMPOSITE TUBULAR OFFSHORE WIND TURBINE TOWERS

description: A double-skinned composite tubular (DSCT) offshore wind power tower was proposed and automatic section design software was developed. The developed software adopted a nonlinear material and nonlinear column model. As long as the outer diameter, material properties, and requested capacities are known for the DSCT wind power tower, the developed software can perform axial force-bending moment-interaction analyses for hundreds of sections of the tower, as well as suggest ten optimized cross-sectional designs. Assuming that the inner and outer tubes were made of steel, the software performed experimental design processes for a 5.0 MW and a 3.6 MW turbine. The software suggested rational and satisfactory section designs, and showed the possibility of a DSCT tower being used as an offshore wind power tower.

title: DISPERSION OF WAVE FORCES ON CAISSON BREAKWATERS USING INTERLOCKING SYSTEMS

description: Interlocking caisson-type breakwaters have recently gained attention for enhancing the stability of the conventional breakwaters. In this study, the dispersion characteristics of wave forces using interlocking systems connecting the upper part of caissons with cables in the normal direction of breakwaters were investigated. Based upon numerical experiments, the higher wave forces are transmitted through the cable as the angle of incident wave increases, while the maximum allowable wave force was capable of being increased by sharing the wave forces with the adjacent caissons. It was also found that the larger the stiffness of the interlocking cable, the larger the wave-dispersion effect.

title: MECHANICAL PROPERTIES OF A PVA FIBER REINFORCED ENGINEERED CEMENTITIOUS COMPOSITE

description: High Performance Fiber Reinforced Cementitious Composites (HPFRCCs) are promising construction materials characterized by tensile strain hardening behavior. Engineered Cementitious Composite (ECC) is a special type of HPFRCC developed with enhanced ductility and durability. Coarse aggregates are usually excluded from the ECC matrix, and the reported ECCs are typically produced with microsilica sand having a maximum grain size of 200 พm. In this paper, a PVA-ECC mixture containing local dune sand with a maximum grain size of 300 พm was developed, and its compressive and tensile properties were experimentally investigated. A dog-bone-shaped specimen and a rectangular-coupon-shaped specimen were both used in the tensile test, and it was found after extensive research that the dog-bone specimen was more suitable than the rectangular coupon specimen. The experimental results from the dog-bone specimens indicated that the newly-developed composite possessed good tensile strain-hardening behavior, with a high ultimate tensile strength, and the compressive strength was comparable to that of existing PVA-ECCs.

title: THE DEVELOPMENT OF WIND FARMS

description: The Eastern Cape in South Africa has been identified as having ideal characteristics for the development of wind farming, and thus the industry has grown in this area. Wind energy has been identified as a tool to create jobs; as the demand for electricity increases and renewable energy sources become a necessity, the South African Government has provided targets and incentives to attract investors into the industry. This study investigates why wind farms attract public resistance. It also investigates if wind energy is expensive compared to other sources of energy in South Africa and the Eastern Cape. A descriptive survey was conducted with two associations related to the study. Essential findings include: The largest impact that wind farm developments have on the environment is their visual pollution. Wind-generated energy provides the best return on investment and the second-best capital cost per megawatt in comparison with other sources of energy. In the Eastern Cape, wind as a resource is consistent enough to realise a financial return, and could be used to a large extent in terms of provision of power to the national grid.

title: SUSTAINABILITY ASSESSMENT OF THE REPLACEMENT OF CLAY BRICK WALLS WITH IN-SITU COMPOSITE SANDWICH WALLS

description: Clay bricks are used for house construction in Western Australia. Clay bricks produce large amounts of construction and demolition waste, and have a large carbon footprint. In order to achieve energy savings and greenhouse gas (GHG) reduction targets, there is a need to use an alternative wall system. The objective of this paper is to undertake a sustainability assessment of the replacement of clay brick walls with in-situ composite sandwich walls (CSW). A Life Cycle Assessment (LCA) tool has been applied to assess the carbon footprint and embodied energy consumption for non-insulated and insulated brick and CSW. The LCA analysis identified the stages or inputs/process causing the most significant impacts for determining further improvement opportunities. The findings indicate that a significant GHG reduction and energy saving can be achieved.

title: DECISION PRINCIPLES FOR ASCENT SUPPORTS IN BUILDING CONSTRUCTION

description: Ladders are the ascent system most commonly used to scale up a building, due to the low initial costs compared to other ascent equipment. The insufficiency of this approach is shown in an economic comparison of ladders, stair towers, and scaffoldings with integrated ascent support. Based on empirical studies, cost data and the current state of scientific knowledge, the ascent support with the highest economic value can be determined by considering safety, cost, time, stress, physical stress and strain, and frequency of use. A survey evaluated vertical transport routes, the ascent systems ladders, stair towers, and scaffoldings with integrated ladders. The findings indicate that from an economic point of view, ladders should be used only on construction sites where less than 54 ascents were performed each day. This leads to the assumption that for typical construction sites, with at least 6 ascents per person per day and a site usage for a period longer than one week, the operation of ladders is uneconomical.

title: MECHANICAL PROPERTIES OF FLY ASH BASED GEOPOLYMER CONCRETE WITH ADDITION OF GGBS

description: Concrete plays an important role in the construction industry worldwide. New technology has made for easier development of new types of construction and alternative materials in the concrete area. Cement is the major component in the production of concrete, but its manufacture causes environmental issues and thus there is a need for alternative materials. Geopolymer concrete is a new type of material with that potential, commonly formed by alkali activation of industrial alumina silicate byproducts, such as fly ash and ground granulated blast furnace slag (GGBS). For this paper, mechanical properties of geopolymer concrete with fly ash and GGBS cured under ambient temperatures were studied. Five different grades of concrete were considered. The results were encouraging: The workability of the geopolymer concrete was similar to that of conventional concrete. Experimental results of flexural and splitting tensile strength revealed insignificant variation compared to conventional concrete. The mechanical properties of fly ash and GGBS-based geopolymer concrete were comparable with conventional concrete.
