  • The livability of spaces: Performance and/or resilience? Reflections on
           the effects of spatial heterogeneity in transport and energy systems and

      Cities can be seen as systems of organized complexity formed by interrelated and highly dynamic sub-systems. This paper reflects on the interactions and tensions between socio-ecological and/or socio-technical sub-systems in cities and their capacity to either improve or block urban processes. In this context, spatial heterogeneity could enhance or hinder the performance and resilience of critical urban sub-systems such as transport and energy. The consequence of this interaction might be detrimental to environmental quality (air and acoustic) and the livability of urban areas. This rationale may improve political and expert decision-making processes toward sustainable, resilient and livable cities.

      This paper presents three pozzolanic materials that were used to make quaternary binders, Granulated blast furnace slag, fly ash (PFA), metakaolin, and silica fume as partial replacement in quaternary binders with Ordinary Portland Cement (OPC) to investigate the effect of standard consistency, initial and final setting times of quaternary paste. Experiments demonstrate that SF has greater influence on the standard consistency of the OPC–FA–SF–GGBS paste, as compare to FA and GGBs. Water requirement in the paste escalates, with increase in SF percentage level within the paste, owing to the high surface area. In case of GGBS, around 3–5% of reduction in water/binder ratio was recorded, whereas for SF, it was 10–12%. In quaternary OPC–FA–SF–GGBS pastes, increases in initial and final setting times at 5%, 7.5%, 10%, and 15% replacement of SF and GGBS were observed, whereas OPC–FA–SF–MK paste setting time shows an increase at 5% replacement of SF and MK with 20% and 70% replacement of FA and OPC, however, it starts decreasing between 7.5% and 15% replacement of SF and MK. The consistency of the quaternary binders increases with an increase in percentage of SF and MK. In general the effect of FA, SF, GGBS and MK reflects in the behavior of quaternary binders even though the performance of all three pozzolans behaves completely independent of each other.

  • Waste glass powder as partial replacement of cement for sustainable
           concrete practice

      Million tons of waste glass is being generated annually all over the world. Once the glass becomes a waste it is disposed as landfills, which is unsustainable as this does not decompose in the environment. Glass is principally composed of silica. Use of milled (ground) waste glass in concrete as partial replacement of cement could be an important step toward development of sustainable (environmentally friendly, energy-efficient and economical) infrastructure systems. When waste glass is milled down to micro size particles, it is expected to undergo pozzolanic reactions with cement hydrates, forming secondary Calcium Silicate Hydrate (C–S–H). In this research chemical properties of both clear and colored glass were evaluated. Chemical analysis of glass and cement samples was determined using X-ray fluorescence (XRF) technique and found minor differences in composition between clear and colored glasses. Flow and compressive strength tests on mortar and concrete were carried out by adding 0–25% ground glass in which water to binder (cement+glass) ratio is kept the same for all replacement levels. With increase in glass addition mortar flow was slightly increased while a minor effect on concrete workability was noted. To evaluate the packing and pozzolanic effects, further tests were also conducted with same mix details and 1% super plasticizing admixture dose (by weight of cement) and generally found an increase in compressive strength of mortars with admixture. As with mortar, concrete cube samples were prepared and tested for strength (until 1year curing). The compressive strength test results indicated that recycled glass mortar and concrete gave better strength compared to control samples. A 20% replacement of cement with waste glass was found convincing considering cost and the environment.

      Driven by a plethora of external and internal influences, the construction industry has independently embraced lean principles and green initiatives. Prima facie significant synergies have been reported between these two paradigms. It is foreseen that when tapped and adopted in unison, these paradigms may yield additional benefits for the construction projects. This synergy is investigated in this research. Further this study identifies and proposes Building Information Modelling (BIM) as an enabler for gaining lean and green project outcomes. The study uses crisp set qualitative comparative analysis (csQCA) method for exploring the causal combinations of different BIM capabilities and asserts that causal combinations of four BIM capabilities: MEP system modelling, energy and environment analysis, constructability analysis and structural analysis, when implemented on construction projects can lead to lean and green outcomes. With the help of sixteen cases it is shown that adoption of BIM leads to improved project outcomes especially ones targeting lean and green aspects.

      Ground granulated blast-furnace slag (designated as GGBS) has been utilized as building material due to the environmental, economic and technical benefits. In this study, the possibility of improving compressive strength of high-volume GGBS (HVS) paste before and after being exposed to elevated temperatures using metakaolin (MK) in micro-size (mMK) has been investigated. Portland cement (PC) has been partially substituted with GGBS at level of 70%, by weight, to produce HVS paste. Afterword, GGBS was partially substituted with mMK at levels ranging from 2% to 10% with an increment of 2%, by weight. After curing, the specimens were subjected to elevated temperatures ranging from 400°C to 1000°C with an interval of 200°C for 2h. Weight and compressive strength before and after being exposed to elevated temperatures have been thoroughly explored. The various decomposition phases formed were identified using X-ray diffraction (XRD) and thermogravimetric (TGA) analyses. The morphology of the formed hydrates was studied using scanning electron microscopy (SEM). The results showed that the compressive strength before and after being exposed to elevated temperatures increased with increasing mMK content. For all mixtures, the residual compressive strength at 400°C reached its maximum peak value.

      Disposal of huge amount of discarded waste materials like plastic, polythene bags, bottles, rubber tyres etc, which are generated in huge quantity and causes environmental hazards after their disposal. Present study attempts to utilize these waste materials as partial replacement of bitumen to develop a modified binder, for making bituminous concrete mix. To simulate with the field conditions, ‘Marshall Stability Analysis’ was performed on the samples prepared by partially replacing ‘Optimum Bitumen Content’ with waste plastic (4%, 6%, 8% and 10%) and crumb rubber (5%, 10% and 15%). Experimental results demonstrate that partial substitution of bitumen with waste plastic results up to 16% increment in strength whereas with rubber material, about 50% increment in strength was observed as compared to the conventional mix (CM). Laboratory testing results indicate that by using waste materials, bituminous concrete of required strength and density can be obtained and an environment friendly green pavement can be prepared with less material cost.

      The Finnish transportation sector is the second biggest greenhouse gas emitting sector in Finland. Despite large-scale investment and government commitments to promote biofuels for transport sectors in Finland, little is known about the public acceptance of this alternative transport fuels. Public’s opinion, awareness and knowledge can contribute to social acceptance of new renewable energy and to the overall improvement of consumers' energy behaviour. This study examines public acceptance in terms of public’s opinion and knowledge about biofuels and their consumer patterns of transportation fuels by designing a multiple-choice questionnaire with four groups of questions: background information, community perspective, social perspective, and market perspective. The analysis of 90 respondents’ survey shows that 50% of the respondents think that there is a direct effect of biofuel production on food prices and would not buy biofuels derived from food crops. Only 60% of them are willing to switch towards purchasing biofuels; however, the lack of information about biofuels prevents them to use biofuels for their transports. Finally, 63 respondents of the car owners, their ideal fuel would be hydrogen (20%), electricity (60%), and other (20%), which meant hybrid. Study findings have important policy implications related to the public acceptance of biofuels in the transport sector.

      Decision making on buildings after the earthquake have always been a great concern of scientists. Safety concerns, possibility of using the building, repairing the building, and the rate of damage are some of the most vital factors that needs to be paid attention in immediate decision makings of the buildings. In order to determine the level of damage in the buildings, the maximum displacement of stories is one of the most important parameter that needs to be investigated. In this paper, a concrete frame with shear wall containing 4-stories and 4-bays has been designed for acceleration records of 0.1g–1.5g and the rate of damage is determined. The total of 450 data with 6 input variables and one output variable is produced. The input parameters are defined as frequency, Vs, Richter, the distance from the earthquake epicentre (DEE), PGA, and acceleration, and the output parameter is defined as drift. With respect to this data set, three different data-driven models, i.e. Artificial Neural Network (ANN), Adaptive Neuro-Fuzzy Inference System (ANFIS), and Multiple Linear Regression Model (MLR) are used to predict the displacements. Results indicate that Both the ANN and ANFIS model show great accuracies in estimating the displacements in concrete frame with shear wall. On the other hand, MLR model did not show acceptable accuracy in the same estimation purposes. Finally, the sensitivity analysis was performed on the data set and it was observed that the accuracy of the predictions highly depends on the number of input parameters. In other words, increasing the number of input parameters would result in the increase in the accuracy of the final prediction results.

      Nearly 30% of total population and over 2million students of Delhi spent above 1/3rd of their daily time in different office buildings and educational institutions of Delhi, of which the ambient air quality is reportedly worst in the globe. However, studies on indoor air quality of non-residential buildings are scarce in India. Present study was conducted in two office buildings and one educational building in Delhi during pre-monsoon. CO2, PM2.5 and VOCs were measured inside each building at every 5min interval between 9:30AM and 5:30PM for 5days every week. The average CO2 concentration in both office buildings (1513ppm and 1338ppm) was recorded much higher than the ASHRAE standard. Ductless air-conditioning system couple with poor air-circulation and active air-filtration could be attributed to significantly higher concentration of PM2.5 in one of the office buildings (43.8μgm−3). However, there was significant variation in the concentration of different pollutants at different locations in a building. Among different non-residential buildings, significantly lower concentration of all pollutants was recorded in the educational building (CO2: 672ppm; PM2.5: 22.8μgm−3 and VOC: 0.08ppm).

      In order to arrest the incidence of global warming brought about by the emission of greenhouse gases notably CO2 into the atmosphere, the use of materials that can substitute the material responsible for greenhouse gases is being promoted world-wide. One of these is rice husk ash (RHA) which has been found suitable by researchers to partially replace Portland cement in the production of concrete. This paper presents a comprehensive and up-to-date review of the work of numerous researchers on structure and properties of concrete containing rice husk ash (RHA) as partial replacement of ordinary Portland cement. Some of the findings are: (i) controlled incineration is required to produce RHA with structure that can result in structural concrete, (ii) the use of RHA resulted in increased water demand, (iii) up to 10% cement replacement with RHA will result in strength development comparable to the control specimens, and (iv) the use of RHA in concrete result in impervious RHA-concrete microstructure to agent of degradation like, sulphate attacks, chloride ingress, etc., as well as good shrinkage properties, and thus produce durable concrete when used. However, some areas such as the bending and shear responses (and allied properties) of reinforced concrete slabs and beams with RHA are presently not yet covered by researchers; they are therefore recommended for future investigation.

  • Nuclear energy: Sense or nonsense for environmental challenges

      Environment is subject to many pressures. Climate change and the global warming constitute an additional pressure. The “climate change” and its consequences are more important than other challenges in 21 century. The global temperature has risen by more than 2.5°C in recent years. Similarly, a global temperature rise of more than 2.5°C increases the absolute number of people at risk of hunger by 80 million. Recent estimates indicate that 25% of the world’s mammals and 12% of birds are at significant risk of global extinction. The main reason for global warming is CO2 increase that is obtained from burn reaction. According to California university, CO2 emissions result from emissions of: transportation 49%, electricity 30%, industrial 11%, residential 7% and commercial 3%. In the mean time, CO2 concentration is 360ppm even, if severity plan will be applied as per Kyoto protocol it will arrive at 450–650ppm in 2100. Thus, there is a global resolution for declining CO2 emission and one of the practical approaches is CO2 decreasing in electricity sector. Each of energies has strengths and weaknesses and we focus more on nuclear energy because its CO2 emission is zero. It should be added, in most of countries there is a tax for gas e.g. in the U.K. 3.4$/gallon and in Italy 2.53 $/gallon, so fossil fuel is an income for their governments but for nuclear energy government pays subsidies. Therefore it is not possible to debate about it before removing tax and subsidy. In recent years, it has been stated about tax on carbon production that it is a step forward to low carbon economy and finding the real cost of fossil fuel with attention to external costs in the environment.

      An attempt has been made to study the subsurface groundwater discharge (SGD) in the coastal Cuddalore region of south east India. Measurement for Radon, water level, Electrical Conductivity (EC) and pH in surface water for a total of twenty hours by hourly interval has been attempted and further correlated with tidal values calculated by WX Tide 32 software. The SGD measurements were made by using a modified seepage meter. The study reveals a match with water level variation and tide with minor variation due to influx of surface water. Saline discharges, fresh groundwater discharges and surface water mixing processes were identified along the coast. Lower SGD (37.24–79.16cm/day) was observed during fresh groundwater discharge.

      Concrete is the most widely used construction material in the world. Cement is the major manufactured material used in the production of concrete. It is an established fact that the manufacturing of one tonne of cement produces about one tonne of CO2, which is a major Green House Gas (GHG), contributing to Global Warming, Climate Change and Ozone layer depletion. In this paper, the environmental impact of cement manufacturing has been assessed on the basis of literature review. The use of Supplementary Cementitious Materials (SCMs) such as Pulverized Fly Ash (PFA) and Ground Granulated Blast Furnace Slag GGBS), Rice Husk Ash (RHA) and Silica Fumes (SF) have been used for reducing the weight of cement in the concrete mixes to achieve, the desired compressive strength of concrete for use in construction projects. Various trial mixes have been used tried with partial substitution of cement with PFA and GGBFS and SF to achieve the desired high strength concrete for structural uses. The addition of the SCM has reduced the cement proportion in concrete, thereby making it relatively sustainable. The results have been assessed on the basis of reduction in the embodied energy of the concrete. The paper presents a holistic review of concrete by using binary cement, incorporating Ground Granulated Blast furnace Slag (GGBS), Pulverized Fly Ash (PFA) and Silica Fumes (SF).

      To test metrics for rapid identification and global evaluation of more sustainable urban forms, we examine the configuration of the São Paulo Metropolitan Region (SPMR) in Brazil using satellite remote sensing data and landscape metrics. We adopt principles from landscape ecology and urban planning to evaluate urban heterogeneity and morphology that may constitute more sustainable urban forms, including connectivity, density, geometric complexity (mixed land use), diversity, and greening. Using 2-D wavelet multiresolution analysis and satellite-derived fractional vegetation cover (Fr), the variability of landscape metrics from Landsat (30 m) to MODIS (1 km) scales are investigated. According to our findings, metrics of Patch Density and Landscape Shape Index can be used at the 1-km scale to asses density and geometric complexity of urban form. With the addition of MODIS land surface temperature (LST) data, available at high temporal resolution, a move away from or toward more sustainable urban forms is defined in relation to mitigation of the urban heat island. As the geometric complexity and density of finer-scale urban characteristics are related to climatic impacts at the neighborhood scale, sustainability assessments may be more attainable across urban areas.

      Buildings contribute 20 to 40% of the world’s energy consumption, making the need to investigate their energy performance a necessity. Given the lack of empirical evidence on the energy performance of school buildings operating under extreme weather conditions, this study aimed to benchmark historical energy consumption over a ten-year period in a sample of 30 school buildings in Manitoba, Canada. Results showed the median total energy consumption of these schools was higher than other Canadian benchmarks. School building age had a statistically significant effect on their energy consumption, with newer schools consuming less gas but more electricity than older and middle-aged ones. The retrofits implemented in some schools did not for the most part have a statistically significant effect on their energy consumption, although a decrease in energy consumption was observed. The results also showed that middle-aged schools were the largest energy consumers, with the results changing depending on the metric used to report on schools’ energy consumption, reinforcing the need to standardize those metrics. There is also a need to investigate how occupancy may be contributing to the increase in electricity consumption in newer schools. This study is the first to provide empirical evidence on existing school buildings’ energy consumption in Manitoba, establishing benchmarks that practitioners can make use of in similar cold climates.

      An overview of recent research related to building renovation has revealed that efforts to date do not address sustainability issues comprehensively. The question then arises in regard to the holistic sustainability objectives within building renovation context. In order to deal with this question, the research adopts a multi-dimensional approach involving literature review, exploration of existing assessment methods and methodologies, individual and focus group interviews, and application of Soft Systems Methodologies (SSM) with Value Focused Thinking (VFT). In doing so, appropriate data about sustainability objectives have been collected and structured, and subsequently verified using a Delphi study. A sustainability framework was developed in cooperation with University of Palermo and Aarhus University to audit, develop and assess building renovation performance, and support decision-making during the project's lifecycle. The paper represents the results of research aiming at addressing sustainability of the entire renovation effort including new categories, criteria, and indicators. The developed framework can be applied during different project stages and to assist in the consideration of the sustainability issues through support of decision-making and communication with relevant stakeholders. Early in a project, it can be used to identify key performance criteria, and later to evaluate/compare the pros and cons of alternative retrofitting solutions either during the design stage or upon the project completion. According to the procedure of the consensus-based process for the development of an effective sustainability decision-making framework which was employed in this study, the outcome can also be considered as an outset step intended for the establishment of a Decision Support Systems (DSS) and assessment tool suited to building renovation context.

      The temperatures of sewage water were too low in cold climatic regions of Baltic Sea, which resulted in inefficiency of denitrification in sewage treatment process (STP). This is not prescribed to meet the effluent nitrogen levels (<10mg/l) as per Urban Wastewater Treatment Directive 98/15/EC. In order to improve the denitrification efficiency and the subsequent removal of nitrogen from the municipal wastewater as per the above European Commission guidelines, modified process was formulated with pre-anaerobic and post-aerobic activated sewage treatment processes. The modified process includes the rise in ambient temperature up to 20±2°C by using heat exchangers in Increased Technology and Efficiency in Sewage Treatment (ITEST) pilot plant at the Swedish Environmental Research Institute (IVL) laboratory. The experiments were conducted with the modified process of sewage water in one line (treatment line (TL)) and the existing process in another line (reference line (RL)) of the pilot plant. The physical (such as Temperature, Suspended solids and Sludge volume) and chemical (ammonium-nitrate (NH4 +-N), nitrate-nitrogen (NO3 −-N) and total-nitrogen (TN)) parameters were analyzed. The results concluded that the NH4 +-N, NO3 −-N and TN concentrations of treated waste water were satisfactory with a concentration of <10mg/l as per the European Directives 98/15/EEC at treatment line as compared to influent and reference lines. The average nitrogenous-compounds’ removal efficiencies were 84% and 76% of NH4 +, 80% and 65% of NO3 −, 78% and 62% of TN for TL and RL, respectively.

      With a purpose to comprehend intention-behaviourgapabout acceptance of solar energy and solar community concept (houses and/or block of flats under specific solar power plant) among Finnish respondents, this qualitative study found respondents’ positive responses towards solar energy and their rationality and honesty in admitting their real behaviour. It focuses on the qualitative interpretation of individual’s intention that corresponds to specific behaviour. In terms of their ‘impression in principle’ by thinking solar energy as a non-polluting, inexhaustible and renewable energy source although all respondents were positive, the highest numbers were non-adopters. However, they were optimists. They mentally accepted (acceptance in principle) solar energy. They would adopt it later on after being satisfied with their mostly contextual conditions (‘impression in practical’). This study provides recommendations that are indicated to more future adoption and future research direction.

      The study examined the factors responsible for the spatial variation in housing quality across the 36 states and the Federal Capital Territory in Nigeria using 33 housing characteristics. The data used is the 2006 Housing Characteristics and Amenities tables which were sourced from Nigeria’s National Population Commission (National Population Commission 2006). Principal Component Analysis extracted three components. Component 1 accounting for 38% has electricity, water closet toilet, hygienic sources of water and high quality roofing, walling and flooring materials highly loaded on it. Component 2 (31%) comprised inferior walling, roofing and flooring materials, pit toilet, traditional and semi-detached house types, while component 3 (7%) had mainly zinc wall and public toilet highly loaded on it. Using these factor loadings as variables in discriminant analysis, three distinct regions of differing housing quality emerged corresponding to the western, eastern and northern geographical regions of the country with 97.3% of the states correctly classified and with the western (high) and northern (low) states at the opposite ends of the quality scale. It is recommended that non-conforming buildings, particularly, residential, and insanitary environment should be put in check through very strict and proactive enforcement of development control edicts and sanitary laws.

      The use of geosynthetic in soil and coastal engineering is increasing and improving due to improvements in its engineering properties and fabrication techniques. While some geosynthetic coastal structures have attained advanced stage in terms of applications and efficiency, others still lack well-structured design formulas and specifications on a sound scientific basis, hence continued experimental works for the better understanding of the hydraulic performance, stability and modes of failure of these structures. Coastal areas are dynamic with unique geomechanical feature such as soil instability, which in any case, may affect the overall performance of coastal defense structures constructed on soft soil or weak foundation. This paper reviews the developments and applications of geosynthetics in soil stabilization and protection of coastal areas with emphasis on shoreline protection. Relevant empirical research data are presented as well as the present and likely future challenges in the use of geosynthetics in soil stabilization and coastal defense structures.

      Due to various kinds of obsolescence, a large number of concrete buildings around the world are removed to give space for new buildings, however, the elements of these buildings in most cases have the ability to serve longer time, but the dominant demolition end-of-life scenario prevents from the reuse of these elements. It has been demonstrated that reuse of elements and materials is an environmentally responsible option that turns the current linear model of building materials and elements into a cyclic one, which pushes toward reconsidering the construction design of concrete buildings to support future disassembly, that facilitate reuse and adaptation. This study tends to explore and review the current issues related to concrete technologies and their role in building assembly and disassembly, as well as DfD “design for disassembly” aspects and theories that clarify and pave the way for future innovations, which move the construction design of concrete buildings to a higher degree of environmental responsibility. The study found out that despite the continuous developments in the field of concrete technologies, the link of these developments to the end-of-life phase is still missing. The study concluded that it is possible through the application of DfD criteria on precast concrete systems and elements to change the liner life-cycle model to a cyclic one.

      A big challenge in sustainable projects is selection of appropriate construction method and is considered to be the decisive factor for its success. Many environment friendly prefabricated elements are entering into the market at an increasing pace. This has increased the workload and inquisitiveness of the stakeholders who will need information about their environmental, technical and esthetic aspects. The use of prefabrication in sustainable construction is advantageous but appropriate decision criteria and their weightage for applicability assessments for a project from every stakeholder’s perspective is found to be deficient. Decisions to use prefabricated elements are still largely based on anecdotal evidence or cost-based evaluation rather than holistic sustainable performance. But authenticated information is seldom available and suitability within the project requirements is always debatable. Environmental decisions, being closely coupled with society’s built-in uncertainties and risks, are uncertain since ecological systems as well as social systems change in the future. Thus the selection of a suitable construction method has been perceived as a multi-criteria decision-making problem highly intensive in knowledge with partial information and uncertainty. This knowledge or perception base from the minds of experts has to be collected and processed for a decision. Fuzzy synthetic evaluation method using analytic hierarchy process by Saaty has been adopted to provide an analytical tool to evaluate the applicability of prefabricated or on-site construction method.

      The worldwide demand for new concrete buildings is increasing at a rapid pace to keep up with urban development. Despite the need, concrete production and its use have a number of environmental consequences. The production of concrete creates a substantial need for water that directly causes a burden on the already scare natural resource. In United Arab Emirates the majority of the water used for concrete production is obtained through desalination of the seawater. Desalination of seawater produces highly saline wastewater commonly known as reject brine or concentrated brine that has numerous negative environmental effects. The production of cement, the primary ingredient in the production of concrete is responsible for the generation of nearly 5% of the global carbon dioxide that is a potent greenhouse gas. With the intent of reducing the carbon footprint of concrete production, a study was carried out to determine the effect of using reject brine as the source of water and the use of ground granulated blast furnace slag (GGBS) as a replacement for cement. Concrete samples having three different cement contents were prepared with normal tap water and reject brine. Results showed that the use of GGBS and reject brine improved the strength of concrete produced by 16.5%. Replacing 50% of the cement with GGBS and using reject brine as the source of water has a potential for reducing 176 kg CO2 and 1.7-3.4 kg of CO2 equivalents per one cubic meter of concrete, respectively. The use of the waste reject brine can potentially save USD 170-340 per cubic meter of concrete produced.

      The importance of local knowledge and traditional practices is now recognized by disaster risk reduction specialists, particularly in the aftermath of the tsunami in the Indian Ocean in 2004. However, these frequently used practices by local populations are not yet recognized by all actors involved in disaster prevention. This research seeks to identify local traditional practices which are connected to hydro-meteorological phenomena and climate change in the coastal areas of the Yucatán Peninsula in the Rio Lagartos Biosphere Reserve. The identification process requires observation, documentation, validation and categorization of local traditional knowledge. The traditional practices (mainly by fishermen as well as some farmers) examined specifically among the coastal populations relate to their habitat, natural resources, and fishing practices. Recognizing and valuing traditional knowledge will help improve resilience to the impact of disasters and the effects of climate change among coastal populations.

      The overarching objective of social housing is to meet housing needs, particularly those of the vulnerable households – low and middle income earners. However, there is evidence to show that social housing is not adequately supported to achieve sustainable goals despite its significance for addressing the housing crisis. The aim of this study is to determine the Critical Success Factors (CSFs) for achieving Sustainable Social Housing (SSH) from economic, environmental and social perspectives for meeting housing needs. The document content analysis approach involving relevant literature resources was used for generating the success factors (SFs) for achieving SSH. Findings from this approach were refined before using them in preparing a questionnaire used to gather data from housing authorities (public) and private non-profit social housing organisations in England and they were asked to rank the criticality level of the identified success factors. The data gathered through the relevant documents and respondents were analysed respectively with NVivo and Statistical Package for Social Science (SPSS). Findings revealed some of the CSFs for achieving SSH for meeting housing needs as: adequate funding and provision, affordability, efficient economic planning, appropriate construction technology, environmental protection, use of environmental friendly materials, effective land use planning, appropriate design, security of lives and property, provision of social services and ensuring social cohesion. The paper recommends the use of efficient sustainable development (SD) strategies and legal and institutional frameworks for monitoring and evaluating the delivery of SSH. The Government must embark on effective housing programmes for ensuring adequate provision of social housing that is sustainable for meeting housing needs in the short and long-run. There is need for the Government to regularly provide financial supports to social housing providers and users for addressing the housing crisis.

      The physical form and pattern of built environment in a city is the outcome of prevalent planning and design standards and building regulations. Many common issues of built environment are the consequence of existing building regulations in that settlement as building regulations are borrowed from other cities and adopted from one place to another across the country. Building regulations are mostly specified for various uses and apply to the particular size of a plot in India, generally, irrespective of the shape and topography of the plot. As a result, often while complying with the provisions of one regulation will lead to noncompliance of provisions of other regulations. This further aggravates the problems of noncompliance with the existing building regulations and often results in unauthorized development and enormous environmental impacts. An attempt is made to understand different issues associated with building regulations of Shimla. Further, the effects of plot proportions on the compliance of building regulations are also studied in the case of Shimla, being the largest hilltop town of northern India on ecologically sensitive topography.

      Improving the mechanical properties of lightweight concrete using waste material is the goal of this work to get both structural and environmental advantage besides cost saving. Porcelanite aggregate was used as lightweight aggregate. First plastic bottles were cut into slices and used as fibers with these percentages: 0.0%, 0.5%, 0.75%, 1.0%, 1.25% and 1.5% by volume. The results of tests under compression and tensile stress showed that mix 1% plastic fiber (PF) gave the best results when compared to reference mix without PF. Eggshell (rich with CaO) and glass wastes (rich of silca) were crashed and powdered to desired size and used as partial replacement of cement with these percentage: 0%, 5%, 10%, 15% and 20%. Compressive strength, flexural strength, density, absorption and modulus of elasticity were tested. Comparison was made with reference mix (without waste powder) to figure the efficiency of using these waste in lightweight Porcelanite concrete. The results of tests showed that mixes with 1% PF and 5% eggshell powder (ESP) gave results so close to reference mix. Using more than 5% ESP made no improvement in lightweight concrete, while the mix with 1% PF with any glass powder (GP) percentages used in this research gave good improvement in the tested properties especially at 20% GP.

      This paper aims at investigating the effect of crumb rubber size and content on hardened characteristics of self-compacting concrete.To this end, different self-compacting concrete mixtures were designed at constant water-to-binder ratio of 0.35 and 520 kg/m3 of binder content. The class F fly ash was replaced with cement as 30% by weight. Six designated crumb rubber contents of 5, 10, 15, 20, and 25% and three different sized crumb rubbers (No.18, No.5, and mixed crumb rubber) were considered as experimental parameters. According to the obtained results, the use of crumb rubber had a negative effect on the hardened properties of self-compacting concretes and the significant improvement was achieved with addition of all tire wastes types, for ductility.

      Rapid development and transformation are the main causes for declining urban natural landscapes as well as its physical and environmental qualities. Currently, rehabilitation and preservation actions cause tough pressures to cities, which lead to serious damages on urban natural landscapes. These fragmentations, particularly in historical heritage cities, cause the riverscapes to lose their sustainability qualities. People’s sense of attachment, satisfaction, and social bonding with riverscape are being also deteriorated. This subject has become one of the most challenging issues for the Malaysian government and its local authorities. This research aimed to establish the sustainable riverscape rehabilitation strategy framework for Malaysia’s historical heritage cities from the urban design and planning perspectives. The research methodology was designed in two phases. Phase one has developed the sustainable riverscape rehabilitation strategy framework for Malaysia’s historical heritage cities by applying the goal-oriented method. The second phase has validated the framework application using the Grounded Group Decision Making (GGDM) method. For validation, the feasibility study shows the expert inputs has reached more than 70% saturation for all feasibility assessment factors, except technical aspect of the factor project potential for extension, which has received 45% saturation. This strategy framework involves sustainability domains; social benefits, environmental quality, and economic growth. Moreover, this strategy framework formulates a sustainable riverscape rehabilitation index score for promoting riverscape preservation. It integrates the Malaysian government, stakeholders, and public participations in riverscape rehabilitation activities.

      Urban blight had its own rational and hierarchical function in the past. Nowadays it is featured with structural and functional shortage. Therefore, it has lost the capacity to meet the residents’ needs. Along with intensification of urban blight problems in cities, and downtowns in particular, which affects different aspects of urban life, many urban planners have shown special attention to such districts. Laleh-Zar neighborhood is an example of these neighborhoods, which on the one hand due to lack of urban equipment’s and infrastructures gives rise to urban blight and penetration of commercial and trans-regional land use in residential area. On the other hand, much of its residential units are transformed into business units, warehouses, workhouse particularly on the edge of the neighborhood. Given the expansion and intensity of problems, apparently, the most effective strategy to deal with the shortcomings and the problems is participation strategy. Besides, this study has used a strategic approach, which is one of the public planning for both internal and external analysis. Therefore, it is a systematic approach, which can be helpful in decision-making. The results showed that the capacity for participation of the study population was below proper level concerning the four aspects of financial, intellectual, instrumental, and physical aspects, although their tendency to participate was high level. Moreover, correlation between participation capacity and intention for participation in renewal the structures had a significant relation with cultural and historical values at confidence level of 99%.

      Customer involvement in infrastructure maintenance activities is a complex process due to various decision-making parameters surrounding maintenance. Compared to manufacturing and other disciplines where QFD is widely used, expectations of the infrastructure user as a customer are truly dynamic given the changing economic conditions, technologies, environmental regulations, etc. While such dynamic or changing customer expectations can be addressed by repeated surveys and constant communication, having indicators to predict customer response would be a valuable tool and aid the QFD decision-making process. In this study, a framework that utilizes hidden Markov model (HMM) is proposed for evaluating customer expectation by using probabilities of focus areas that are of interest to the infrastructure user as hidden parameters. The focus areas are based on sustainability parameters and include economic, social, technological, maintenance efficiency, safety and environmental conditions. Probabilities that represent the probability of transition from current state (of the focus area) to next possible state were generated based on expert opinion of the authors. Using the 2005 customer survey by California Transportation, a case study is presented in order to demonstrate the application which concludes that the proposed methodology can be successfully implemented for infrastructure maintenance.

      In this paper is presented an approach for landfill leachate treatment using enhanced natural evaporation. Experimental set up considered using a greenhouse pilot prototype placed into the municipal landfill of Puebla city, México. The greenhouse was built with a basement surface enough to place 9 trays with leachate. Treatment follow up was done through the following parameters: air temperature inside and outside the greenhouse; leachate temperature at surface and middle liquid height. Results of the first set of experiments defined a minimal initial liquid height of 20% in respect to the tray height; the 2nd set allowed defining optimal evaporation rate conditions evaluated in respect of a tray placed outside, considered as reference of 100% efficiency (blank), obtained results showed that morning and night processes provided efficiencies up to 2 times the reference; otherwise, afternoon measurements showed similar temperature values inside and outside. In general collected data at winter season provided efficiencies between 82% and 147%, in periods of 24h, it was observed that higher liquid reductions took place at North, and lower ones at the South positions. Based on these results it was proposed a 20days experiment, using stagnant (E) and recharge (R) conditions referred to the blank (L), the R process showed greater efficiency (168%) than the stagnant one (158%). Leachate chemical characterization indicates that pH is highly stable; while total solids, chemical oxygen demand, sulfate and chloride exhibit an increase in concentration reaching values of 1.2–2.5times the initial concentration, phosphate was the only parameter exhibiting a decreasing trend ending with 40% of its initial concentration.

      This paper proposes quantitative research methods with the application of Computational Fluid Dynamics (CFD) and EcoTect tools for a sustainable urban design project. This paper is part of a funded research study and was completed in 2010. This study is part of the larger project for planning and development of Cao Fei Dian Eco-city development in North-Eastern China; one of the first eco-city development projects in the first batch of pilot eco-cities in China. The research programme addresses the main aspects of good practice in terms of eco-design and sustainability. These aspects include wind flow analysis around buildings, insolation analysis of open spaces, pollutant dispersion in water systems and noise control on urban highways. This study aims to explore a range of research methods in order to enhance the performance of integrated design with a comprehensive planning stage. The pros and cons, alongside other deficiencies in current forms of comprehensive plan are to be explored further. The integration in evaluation across professions and subject boundaries is emphasised to identify the key gaps between sustainability and design. The main method of this study is the application of CFD and EcoTect tools for environmental performance of a larger urban area than architectural interventions or immediate outdoor spaces of a project. This study suggests an integrated urban design model with the application of computational tools (i.e. CFD and Ecotect in here) and how these could utilise a more comprehensive approach to executing best practice in design and planning from a technical dimension. The paper concludes by suggesting an integrated model of urban design to achieve urban sustainability.

      The hedonic pricing model (HPM) technique has been widely adopted for property price appraisal by scholars and professionals in different real estate markets around the world. Despite its popularity in this research domain, the trend of the application of HPM in Nigeria, being the largest economy in Africa has not been documented. This study, therefore, aims to critically review the extant literature of the HPM property price appraisal related articles published in Nigeria. Papers published in this research area were retrieved from online databases and search engines. The authors’ contributions, authors’ affiliations, the focused study areas and the annual publication trend of the articles were reviewed. The first application of HPM in Nigeria was recorded in 1986. Thereafter, there has been fluctuations in the number of annual publications. However, there has being a considerable number of articles published since 2010. The authors have largely focused on the Lagos metropolis property market as a study area. It was also found that most of the authors were university scholars and on the other side, real estate professionals have not contributed significantly to this research topic. In order to achieve a sustainable real estate practice in Nigeria, the gap between theory and practice should be bridged.

      The increase outdoor temperature acts directly on the indoor climate of buildings. In Cameroon, the energy consumption demand in the buildings sector has been rapidly increasing in recent years; so well that energy supply does not always satisfy demand. Thermal insulation technology can be one of the leading method for reducing energy consumption in these new buildings. However, choosing the thickness of the insulation material often causes high insulation costs. In the present study, the optimum insulation thickness, energy saving and payback period were calculated for buildings in Yaoundé and Garoua cities, located in two climate regions in Cameroon.The economic model including the cost of insulation material and the present value of energy consumption and the cost over a life time of 22 years of the building, were used to find the optimum insulation thickness,energy saving, and payback period. Materials that extruded polystyrene were chosen and used for two typical wall structures (Concrete block(HCB) and compressed stabilized earth block wall (CSEB)).They early cooling transmission loads, according to wall orientations and percentage of radiation blocked were calculated using the explicit finite-difference method under steady periodic conditions. As a result, it was found that the west- and east-facing walls are the least favourite in the cooling season, whereas the south and north orientations are the most economical. Although wall orientation had a significant effect on the optimum insulation thickness, it had a more significant effect on energy savings. In equatorial region(Yaoundé), for south orientation, the optimum insulation thickness was 0.08 m for an energy savings of 51.69 $/m2. Meanwhile, in tropical region(Garoua), for north orientation, the optimum insulation thickness was 0.11 m for an energy savings of 97.82 $/m2.

      When analyzing urban accessibility at a neighborhood scale, the pressure of parking is determinant to decide whether using a private car is an option for accessing local facilities or not. This paper intends to analyze the impact of different parking pressure characteristics in the estimation of local accessibility. Short trips to pharmacies, groceries, bakeries and primary schools were analyzed and a comparison of accessibility indicators for walking and car was made, considering four different parking scenarios. The methodology was applied to two different neighborhoods in the city of Lisbon, with significant differences in their urban planning and mobility patterns. The results obtained show that, for a neighborhood with high walking accessibility, only a low parking pressure scenario would have better indicators when compared to the walking mode. The increase in 5min in the time for the search for a parking place represents a decrease in the accessibility indicators in more than 20% and an elimination of the parking searching time plus a reduction of the distance to destination up to 25m can increase accessibility up to 47%. However, in areas more car-oriented, parking management can lead to significant reductions in car attractiveness. Only a high or very high pressure parking scenario would be less attractive than the walking mode. The parking policies could lead to a decrease in 80% of the car accessibility. Yet, this kind of measure would not represent a better overall accessibility to the neighborhood, contributing, however to a lower use of the motorized modes.

      Healthcare facilities throughout Europe are constantly changing to support efforts to provide efficient healthcare services with decreasing resources. Recent changes include larger and more specialist hospitals to achieve economies of scale. This approach has yet to be proven to sustainably respond to the demands, and efficiently satisfy the users’ needs. The evidence that supports larger healthcare facilities as more cost effective is limited and contradictory as wider sustainability issues need to be given greater consideration. This information paper presents the findings of a comprehensive literature review that addresses aspects that can lead to sustainable small healthcare facilities. It also establishes sustainable-related factors, including economics and energy efficiency, which could be employed to evaluate the viability of healthcare facilities. A typical small-scale facility provides a case study that contextualises these factors, captures their interdependencies, and explores the viability and sustainability of small hospitals. The findings from the work suggest that small facilities can be viable and more comprehensive research that provides a balanced view of economies of scale is required to support future healthcare design policies, where large and more specialised hospitals may no longer be environmentally, technologically, socially and economically sustainable.

      This work aimed to investigate effecting of using plastic waste as partial replacement of fine aggregate, on the fresh characteristics of self-compacting concrete (SSC). For this purpose, different self-compacting concrete mixes were designed at constant water-to-binder ratio of 0.32 and 520 kg/m3 of binder content. The class F fly ash was replaced with cement as 30% by weight. The six designated plastic waste contents of 0,2.5, 5, 7.5, 10, and 12.5% and three different sized Plastic wastes (Fine Plastic wastes, Coarse Plastic wastes, and Mixed Plastic waste) were considered as experimental parameters. The workability properties of self-compacting concrete mixtures were performed regarding to slump flow diameter, T50 slump flow time, V-funnel flow time, L-box height ratio, and L-box T20 and T40 flow times. The 28-day compressive strengths of self-compacting concretes were also measured. The experimental results of this work are showed that the plastic waste with the sizes and contents that used in this work can be used successfully as a fine aggregate in self-compacting.

      This study discusses the future directions of effective Design for Deconstruction (DfD) using BIM-based approach to design coordination. After a review of extant literatures on existing DfD practices and tools, it became evident that none of the tools is BIM compliant and that BIM implementation has been ignored for end-of-life activities. To understand how BIM could be employed for DfD and to identify essential functionalities for a BIM-based deconstruction tool, Focus Group Interviews (FGIs) were conducted with professionals who have utilised BIM on their projects. The interview transcripts of the FGIs were analysed using descriptive interpretive analysis to identify common themes based on the experiences of the participants. The themes highlight functionalities of BIM in driving effective DfD process, which include improved collaboration among stakeholders, visualisation of deconstruction process, identification of recoverable materials, deconstruction plan development, performance analysis and simulation of end-of-life alternatives, improved building lifecycle management, and interoperability with existing BIM software. The results provide the needed technological support for developing tools for BIM compliant DfD tools.
