Lightweight and prefabricated construction as a path to energy efficient buildings: thermal design and execution challenges
by Eduardo Roque, Rui Oliveira, Ricardo Almeida, Romeu Vicente, António Figueiredo
Abstract: Energy efficient buildings start with a building design stage based on a strong background in building physics and construction technology. Traditionally, in southern European countries, massive construction solutions have always been associated with better thermal performance and more suited to easily comply with different performance and construction code criteria. However, lightweight construction systems have the potential to achieve clear benefits over traditional heavyweight construction. The market share of lightweight construction systems, from steel to timber, has grown significantly in the last two decades in countries that traditionally do not have strong background and workmanship on this construction type. Thus, two case studies were detailed presented, combining lightweight construction systems and Passive House concept, with the goals of energy efficiency and thermal comfort. The results highlight the advantages of these systems both from an economical (cost-efficiency and speed of construction) and environmental point of view (recycling, waste production and reuse).
Some drawbacks of lightweight building solutions have been pointed out, from low thermal inertia, overheating, airtightness, thermal bridging (building connections and assembly), higher susceptibility to moisture transfer, shading control, etc. Due to the possible low thermal inertia of this constructive technology, a new wall solution incorporating phase change materials was tested and thermally characterised. This solution could be applied in lightweight constructions, enhancing their energy efficiency and thermal inertia, further promoting the sustainability of these building solutions. In fact, all these issues have been overcome and are highly addressable in the design stage and considered in the latest developments on lightweight construction building systems.

The Effect of Awareness, Knowledge and Cost on Intention to Adopt Green Building Practices
by Redhwan Mohammed Saleh, Marhana Mohamed Anuar, Abdullah Kaid Al Swidi, Khatijah Omar
Abstract: Addressing the threats of climate change has become one of the worlds major challenges. More than 36 billion tonnes of carbon dioxide emissions have been recorded recently and the construction industry has been identified as one of the culprits in the worsening of climate change phenomena. Previous studies have revealed that conventional construction procedures are having a major impact on the environment. In light of these circumstances, this study examines the relationship among some influential and environmental factors including awareness of environmental issues, knowledge of green practices, cost of green materials, subjective norms, attitudes, perceived behavioural control and intention to adopt green building practices in Qatar. The data were collected from 378 engineers using a survey method and were analysed using PLS-SEM. The findings confirmed that significant relationships exist among all variables except for the effect of perceived behaviour control on intention to adopt green building practices. This study provides valuable insight that may help decision makers to plan for strategies to increase the adoption of green building practices among construction companies.

Re-examining sustainable development in Europe: a Data Envelopment Approach
by Tihana Škrinjarić
Abstract: Sustainable development is a widely known concept in public and academic circles and in macroeconomic policy as well. This study applies Data Envelopment Analysis to 37 European countries for the period 2004-2016 in order to evaluate sustainable development objectively. The model uses GDP (Gross Domestic Product) per capita as desirable output, CO2 emissions and Gini Index as undesirable outputs and 3 input variables: unemployment rate, fixed capital formation and energy consumption. In that way all 3 pillars of sustainable development are included in the analysis. This is the first comprehensive analysis of European countries carried out with this methodology. Several model specifications are observed, in order to check for robustness of results and rankings. The results indicate that those countries which are already highly ranked by existing world indices (such as the United Nations and similar organizations) are ranked similarly in the empirical results of this research. Moreover, the most inefficient countries have shown an increase in sustainable development efficiency score over the observed period.
Keywords: sustainable development; data envelopment analysis; performance; undesirable output.
Prospect of Clean Coal for Sustainable Energy Mix in Malaysia
by Siti Fatihah Salleh, Abul Quasem Al Amin, Tuan Ab Rashid Tuan Abdullah
Abstract: This study evaluates the current energy diversification policy in Malaysia and proposes clean coal as an alternative to address the environmental issues and economic sustainability concerns in the power generation sector. In order to clearly picture the competitiveness of the proposed alternative, this study explored two scenarios, namely Scenario a and Scenario b. The former scenario acts as a baseline, where the conventional coal is consumed for power generation, while the latter scenario looks at the prospect of substituting the conventional coal with clean coal by 5%, 10% and 15%. Mixed with four other energy sources specified in the Five-fuel Diversification Strategy for power generation, the total amount of GHG that would be generated is estimated for both scenarios. It was found that the substitution approach could reduce the greenhouse gas (GHG) emission significantly up to 63%, from 823,498 million tones (Mt) by the year 2020. The findings highlight the potential of clean coal as a healthy alternative in reaching the Intended Nationally Determined Contribution (INDC)s target on GHG emission reduction. The results would lessen the gap between the GHG mitigation potential and the INDC target and would aid the formulation of effective energy strategy for power generation in Malaysia.

Manoeuvring SME Beach Resorts in Choppy Environment: Entrepreneurs Perspective
by Mazlina Mustapha, Khairil Wahidin Awang
Abstract: This study seeks to understand how entrepreneurs of SME beach resorts mitigate challenges in their efforts to survive and simultaneously expand their businesses. SMEs in tourism related industry including beach resorts cater towards accommodating increased number of tourist arrivals. Malaysia targets to bring in 36 million tourists, with RM168 billion tourism receipts by the year 2020. The sun, sea and sand are naturally the magnets of tropical islands of Malaysia. The authors employed in-depth interview technique on two resorts located on Perhentian Kecil Island, offshore Terengganu, Malaysia. Observation of the premises complements data collected from interviews. Findings suggest that the resorts employed various strategies to manage their operations. Cost saving methods like employing family members, constructing additional resort features during monsoon period and smart business arrangement with resorts suppliers contributed towards resorts expansion. The study outcome would amongst others benefit policymakers in nurturing the SME sector, further facilitating Malaysia towards a developed nation. This study also contributes to the performance management literature particularly on island beach resorts.

Mechanisms used by chemical manufacturing firms to promote green skills among employees: A case study in Malaysia
by J.S. Keshminder, Chuah Soo Cheng
Abstract: Threats imposed by climate change have raised the demand for green skills. Firms that provide green skills to their employees are touted to respond quickly to green policies and develop the capabilities to implement superior strategies to mitigate climate change. This study seeks to explore the mechanisms used by manufacturing firms to promote green skills among their employees. A case study approach using semi-structured interviews was deployed to explore these mechanisms in six large chemical manufacturing firms. The results indicate that collective effort, self-realization and continuous awareness were the three main mechanisms used by firms to promote green skills among their employees. Firms actively engage employees from every level of management together to upgrade their skills. Pay raise and promotion are used as an incentive by firms to encourage the employees to obtain green skills. This study proposes a green skills development mechanism for policy makers and managers to nurture and invigorate green skills among employees.

Religion and pro-environmental behaviour: A comparative analysis towards environmental protection
by Abdullah Mohammad Syafiq, J.S. Keshminder
Abstract: Faith factors strongly influence pro-environmental behaviours toward proactively solving environmental problems. This paper investigates different faith traditions and their link to the concept of environmental protection rooted within the major religions in Malaysia. In addition to a systematic literature review, data were collected using a cross-sectional qualitative study based on interviews with religious experts in Islam, Christianity, Buddhism and Hinduism. The study found that the religions of Islam, Buddhism, Christianity and Hinduism strictly prohibit the mismanagement of the environment. These religions dictate that one of the core responsibilities of humans is to act as caretaker of the Earth and its population. These religions are also believed to restore faith in protecting the environment and have the potential to be an effective medium to promote pro-environmental behaviour. This study proposes that the Malaysian Government integrate the element of religion in environmental policies that are used to nurture pro-environmental behaviour. Major mediums, such as education and media that are used to promote environmental awareness, should use religion as an element to heighten pro-environmental behaviour in order to cultivate sustainable communities.
Keywords: Religion; pro-environmental behaviour; sustainable communities; environment; Malaysia.
Management of climate change risks in Indian organisations: A proposed framework
by Aditee Potdar, Seema Unnikrishnan
Abstract: This study focuses on determining how climate change risks affect Indian organisations. A framework consisting of four steps (monitoring, analysis, evaluation, and implementation) is proposed to guide organisations to address the climate change challenge. Climate change risks, drivers, and mitigation actions were evaluated by designing a questionnaire and overseeing it to 257 manufacturing organisations. The findings from this study suggest that energy and its price may influence a major impact of climate change challenge. The respondents view on competitive risk is found as the most critical climate change threat. Top management commitment is viewed as a key driver to propose a likely framework. The mitigation action that most organisations have undertaken is energy efficiency. Further, multiple regression analysis shows a significant relationship between climate change risks and drivers, and climate change risks and mitigation activities. The outcomes from this study will be useful for organisations to determine the potential risks and ascertain further actions to mitigate them for India and elsewhere.
Keywords: climate change risk; climate change impacts; drivers for climate change mitigation; mitigation actions; business organisations.
Tipping Points toward Urban Pollution Advantage? - Scaling of Carbon Dioxide Emissions in the American Urban Areas -
by Yu Sang Chang, Seongmin Jeon
Abstract: The high level of urbanization in America may have generated very high CO2 emissions by cities. We examine the scaling relationship of CO2 emission as a function of population size for a very large number of American cities. We conduct scaling analyses on multiple subgroups with varying population size of cities. Our finding indicates that superlinear or linear scaling for the total sample of cities change to sublinear scaling for the subgroups of more populous cities. We also find the tipping point toward such sublinear scaling at the subgroup of top 75 most populous cities. Implications from our findings will be discussed.

Impacts of Health and Economic Costs on Street Children Working as Waste Collectors in Dhaka City
by Md. Mahmudul Alam, Mohammad Saeed Hossain, Nurul Islam, Md Wahid Murad, Niaz Ahmed Khan
Abstract: In the developing world, many children are working in risky, unhealthy and hazardous environments, which impact significantly on their lives and at great economic cost to them. To understand what is happening in Bangladesh, this research investigates the health impacts and access to health services by children who work in the street waste collection industry in Dhaka, the capital city. This study uses both qualitative and quantitative data analysis techniques. Qualitative data were collected through expert interviews and personal observations, while quantitative data were gathered through a face-to-face questionnaire survey given to 50 street children who collected waste at the landfill site located in Dhaka citys Matuail area. The results indicate that 94% of these children have suffered from many health problems, such as fever and fatigue due to tiredness, dizziness, and vomiting. Consequently, a significant portion of their daily income is spent on medical treatment. This study suggests that the waste collection system must integrate modern technological, health and environmental resources so that: firstly, they do not harm waste collectors; and secondly, rehabilitate the street children and give them better access to acceptable basic amenities. This is a priority the city authorities.

The role of energy efficiency in the management of water resources of the Syr Darya river basin
by Eunice Ramos, Annukka Lipponen, Mark Howells, Constantinos Taliotis
Abstract: A motivation for integrated resource assessments is that they can capture indirect effects. Policies in one sector are often developed with limited consideration of their indirect impact on other sectors. This work focuses on the analysis of the implications of electricity efficiency measures on other sectors. The spatial scope includes the four states that share the Syr Darya River basin.
Different interests dictate the management of water resources in the basin. Water resources are the backbone of electricity generation upstream. They are necessary for irrigation downstream. These two uses require water at different times of the year. Upstream nations produce hydroelectricity in winter. They empty reservoirs, leaving little water left during spring and summer. Yet in spring and summer, water is needed for irrigating agriculture. The study investigated options to decrease the need for electricity upstream. Thereby reducing hydro generation requirements and, in turn, reducing winter water requirements. Electricity needs were assumed to be reduced in a scenario that increased the efficiency of energy use. Further, the expansion of regional electricity trade in the period of 2015 - 2030 was also considered as an option to reduce the need to use hydropower in winter. The scenarios were simulated by developing and using a multi-country electricity system model. The model was generated using the Open Source energy Modelling System (OSeMOSYS). The results show that with aggressive energy efficiency measures, less hydro capacity is needed and less water required in winter. The water is stored and available for summer use at no extra cost to the upstream country.
Keywords: transboundary river basin cooperation; energy efficiency; energy systems modelling; water resources management.
Examining the Motivational Factors of Green IT Intention in Malaysia
by Hartini Abdul Jalil, Wan Edura Wan Rashid, Erne Suzila Kassim
Abstract: This study aims to examine the influence of eco-motivational factors measured by eco-efficiency, eco-effectiveness, eco-process and eco-brand on the intention to adopt Green IT. To have a better outcome on the Green IT, a quantitative analysis was performed. The results suggest that all relationships between eco-efficiency, eco-effectiveness, eco-process and eco-brand explored (e.g. predictors) were supported except for eco-process. In comparing the strength of the predictors, eco-brand plays the most vital role, followed by eco-effectiveness and eco-efficiency. Henceforth, all study predictors recognised as the champion in Green IT matters. By using the study outcomes, a Green IT adoption framework could be established for safeguarding the environment from unnecessary e-waste. The study contributes to the environmental literature in an area that has become a fundamental issue and yet lacking in the particular research outcome. The findings of this study will be useful for the policymaker to oversee the interaction between economic drive, Green IT and sustainable environment.

Staircase Evacuation for Public Multi-Storey Housing in Malaysia
by Nurul Liyana Hanapi, Sabarinah Sh Ahmad, Norhati Ibrahim, Azli Abd Razak
Abstract: There has been some concern about the evacuation safety aspects in older affordable multi-storey housing for the lower income group in Malaysia as the number of occupants has been increasing over the years. The multi-storey public housing type has multiplied albeit with its own challenges. This paper aims to study the effects of increased occupancy towards evacuation duration in public multi-storey housing in Malaysia, to gain a better understanding of evacuation safety. The research methodology is through a simulation study using Pathfinder software. This paper focuses on the evacuation process in public multi-storey housing, mainly on the staircase availability and location, in relation to the increasing number of evacuees. The data analysed include the duration taken by occupants to reach safety and their movement patterns during evacuation through a simulation study. A 17-storey residential building is modelled in the programme and the effects of staircases with varied availability and locations on the evacuees are tested. Nine scenarios are considered. Results show that higher number of occupancies and non-availability of the staircase could prolong the evacuation. Moreover, the location of staircases does not influence the evacuation time but contributes significant changes to the movement of the evacuees.

Are Environmentally Responsible Behaviours Shaped by Environmental Facilitating Conditions and Antecedent of Attitudes? The Case of Perak in Malaysia
by Ai Na Seow, Yuen Onn Choong, Lin Sea Lau, Chee Keong Choong, Chun T'ing Loh, You How Go, Suet Ling Ching, Kwang Jing Yii
Abstract: This research attempts to present the notion of understanding through the empirical studies on environmentally responsible behaviour for strategies development with an emphasis on the role of facilitating conditions. A total of 263 usable questionnaire responses were collected for data analysis. The major findings show that environmental concern and environmental knowledge are important for environmental attitude in order to cultivate the environmentally responsible behaviour among tourists. Conversely, environmental facilitating conditions are directly related to environmentally responsible behaviour instead of having the moderating effect on environmental attitude. This study contributed in reassuring the tourists participation in the environmentally responsible behaviour with commitment in environmental concerns and interest in knowledge towards environmental and sustainability issues while visiting natural sites.

A Comparative Requirement of Space Design: Green and Open Space Analysis
by Puziah Ahmad, Muhamad Sharrifullah Hashim, Alamah Misni, Siti Mazwin Kamaruddin
Abstract: Planning guideline is a document that governs the design process of our physical environment. It is important in ensuring urban spatial development to oversee whether that is healthy, safe, attractive, and economically viable. This study focused on studying a few sets of planning guidelines, namely for Selangor, Melaka, and Johor States in Malaysia. To have a good outcome, this study compared and analysed the open and green space requirements on the six elements for landuse development. An assessment of the guidelines was done using several variables, such as (i) the amount of open and green space required, (ii) vegetation characteristic, (iii) green space distribution and (iv) configuration. The study findings by the content analysis and ordinal scale assessment suggested that the existing planning guidelines have not been specific on the provision and design aspect for the open and green space. This study suggests some feasible motivations in planning for the enriched open green space guidelines.

by Mohamad Sufian Hasim, Mohd Khairul Anuar Jalil, Lilis Shereena Safiee, Ellemy Iskandar Khalid, Qi Jie Kwong
Abstract: Facilities Management (FM) has been recognised as one of the most important entities in supporting the goal of sustainability within organisations. Sustainability in FM practices is benefiting an organisation in achieving sustainable environmental, economic, and social improvement. Organisational performance towards sustainability has a significant relationship with the drivers, whether from internal or external sources. This study aimed to determine the factors within FM practices that could enhance sustainability practices in university organisations. To achieve the above aim, ten (10) face-to-face semi-structured interviews at all three South Australian Universities were administered to gather in-depth information involving Heads of Department and those at senior managerial level in the universitys FM department. The analysis has established ten (10) themes, and the most frequent factors in South Australian universities were pressures from stakeholders (28%) (i.e. from students and staff, or governments); economic benefit (26.5%) (i.e. business opportunity and cost reduction); commitment by top management (18%) (i.e. executive level, embedded in university strategic goal); and collaborations with other parties (7.5%) (i.e. local government, state government or private companies). The information gathered will help other organisations as prospects of lessons learned especially for universities in other countries.

Occupants' Satisfaction towards Interior Design Quality at Inpatient Units of Public Hospitals in Malaysia: A Sustainable Development Framework
by Shariffah Syafiqah Aljunid, Mohd Zafrullah Mohd Taib, Zanariah Abu Samah
Abstract: Hospital building is one of the most complex architectures in types and designs for maintaining various regulations, technical requirements and physical environment. It is quite obvious that the physical environment plays an important role in occupants' well-being especially in hospital settings. This study aims to measure the level of satisfaction among users for the public hospitals interior design quality at inpatient units in the Klang Valley region, Malaysia. A combination of qualitative and quantitative methods was employed for exploring the occupants' satisfaction. Respondents were found least satisfied with the space planning (mean score=3.10, sd=0.84) and furniture (mean score=3.01, sd=0.77) from the preliminary analyses. However, safety features (mean score=3.57, sd=0.83) were found the most contented aspect for the occupants' satisfaction. Although the respondents seemed to be fairly satisfied with the aspect of privacy (mean score=3.38, sd=0.93); however, the qualitative exploration verified differently. This study disclosed the users level of satisfaction based on the quality of the interior design that will provide useful input for healthcare planners to design better hospitals environment.

Measurement of green industrial performance: an enhanced GIP index
by Jaime Moll De Alba, Valentin Todorov
Abstract: The green industrial performance (GIP) index provides a tool to analyse and compare the performance of economies in terms of green manufacturing. The demands for and expectations for sustainable development seem not matched with the existence of an analytical framework to measure how green the industrial sector of a given economy is. In this article, we introduce significant methodological improvements to the GIP index.
In previous research, we developed and tested a set of indicators covering the various facets of the green industrial performance of economies. We also introduced a composite index to rank economies according to their green industrial performance. In this article, we address some limitations of the index. To improve the non-satisfactory data coverage, we investigate alternative imputation methods. We also refine our list of green products; and test new outlier detection methods.
Keywords: Inclusive and sustainable development; composite index; green industry.
Alternative forms of sustainable development: The case of thermal tourism
by Stavroula Georgakopoulou, Vassiliki Delitheou
Abstract: Thermal tourism is a special form of providing tourist services at special facilities that use recognized thermal natural resources. Thermal tourism blooms in Europe with pioneer country Germany. There are 1,400 developed bathing sites in Europe, visited by millions of patients from all over the world. This industry employs about 750,000 people and has an annual turnover of approximately 45 billion euros. In Greece, thermal tourism is an important part of the countrys cultural heritage and not only because Greece is one of the richest countries in natural sources with excellent quality water. Despite the fact that Greece is the first country in Europe in the quality and uniqueness of natural thermal resources, its thermal tourism is declining. Furthermore, in this article, efforts will be made to identify the causes that contribute to the reduction of thermal tourism, as well as to draw some conclusions with a view to improving and sustaining the thermal tourism.

Sustainability of textile waste-water management by using an integrated fuzzy AHP-TOPSIS method: A case study
by PUNYASLOKA PATTNAIK, Govind Sharan Dangayach
Abstract: The textile industry is quickly growing worldwide and has a universally beneficial effect on the economy. The waste-water generated with the growth of the textile industry can cause considerable health and environmental issues if it is not treated properly. Generally, physical, biological, and chemical processes are used independently or in combination to treat textile waste-water. The efficiency of any treatment process depends on the working criteria. In this paper, we implemented a new hybrid methodology based on the fuzzy analytic hierarchy process (FAHP) and fuzzy technique for order preference by similarity to ideal solution (FTOPSIS) to help workers in textile industries select the optimal waste-water treatment process. To illustrate how this hybrid methodology can be used to address the waste-water treatment problem, we conducted a case study involving 11 assessment criteria and four treatment process used in the textile industry in India. Comparative analysis indicated that the survey overall mean was slightly lower than the overall mean for selected companies in the treatment process.

The influence of environmental management accounting practices on environmental performance in small-medium manufacturing in Malaysia
by Rapiah Mohamed, Che Zuriana Muhammad Jamil
Abstract: The purpose of this study is to investigate the influence of environmental management accounting (EMA) practices on environmental performance in the small-medium sized (SME) manufacturing sector. The empirical data was collected through structured questionnaires that were distributed to the managers. The study results reveal that physical EMA has the highest mean score compared to monetary EMA, however, unfortunately the EMA practice is not at an encouraging level in Malaysia. The regression results indicate that both types of EMA practices (monetary and physical) have a positive and significant effect on environmental performance. Thus, this study demonstrates the importance of EMA in enhancing environmental performance. The study results are valuable to policy makers, managers of manufacturing SMEs and other sectors to appreciate EMA practices. The study findings contribute to a growing body of literature on EMA within the Asian context, particularly, Malaysia. Finally, this study shed lights on the extent to which EMA tools has been used amongst manufacturing SMEs and provides a good foundation and framework for future studies

Islamic Bankers Green Behaviour for the Growth of Green Banking in Malaysia
by Qaisar Ali, Shazia Parveen
Abstract: Rising concerns for environmental sustainability (ES) demand that Islamic finance converts its business model to ethical finance. The conversion of a business model is unattainable without employees positive attitudes and willingness to adopt the green banking approach. This study aims to promote ES implications for Islamic bankers and encourage Islamic banks to adopt a similar approach. The main objective is to explore green behaviours among Islamic bankers and the influence of these behaviours on green banking growth in Malaysia. Data were collected from 55 Islamic bankers using a survey questionnaire. The findings show that Islamic bankers inclusive green behaviour significantly influences green banking growth. All five types of green behaviours (e.g. conservation, work sustainability, avoiding harm, influencing others and taking initiative) have a significant positive impact on green banking growth. Regulators and policymakers may adopt these findings to develop green banking regulations in Malaysia and other locations with similar economic settings.

The Impact of Spatial Development on Water Pollution: A Comparative Assessment of River Water Quality in Two Municipalities in Malaysia
by Hamidi Ismail, Tuan Pah Rokiah Syed Hussain, Muhammad Subhan
Abstract: This study is aimed at understanding different level of pollution of the river water in two municipalities in Malaysia as a result of spatial development activities. Both municipalities represent the central and southern zones of Peninsular Malaysia which are prone to river water quality problems due to logging, land clearing and livestock farming. Frequency and trend analysis are applied to the data obtained from the Department of Environment (DOE) and measurement of the water quality in the field is conducted in both areas. The results show that the rivers in both municipalities are experiencing deterioration of water quality. The decline in the river water quality is closely related to human activities in urban space and the ineffective environmental management system by the government. The apparent environmental problems indicate that the present management system should be improved to create an urban ecosystem which is really capable of addressing the issues of river water pollution.

Population ageing and energy consumption for sustainable development
by Nur A'mirah Mohd Yaziz, Azlina Abd.Aziz
Abstract: Population ageing has been acknowledged as a cause of the alteration in residential energy consumption pattern, which partly arises from the exit of the workforce from the labour market due to the retirement age limit, promoting a sedentary lifestyle. However, there is a lack of research exploring the shift in energy demand that specifically scrutinises the effect of population ageing on the consumption structure. In this context, the paper aims to investigate the relationship between residential electricity consumption and demographic indicators specific to labour force participation. This study uses a literature survey of household consumption structure, ageing labour force participation, and energy consumption factors, while the econometric approach is proposed to estimate the determinants. Based on the findings, this study supports the inclusion of the employment rate in expressing residential electricity consumption in the population ageing scenario. This paper ends with the development of a proposed model for future research work due to the economics of population ageing in energy.
