The purpose of this paper is to examine significant steps taken by the Pennsylvania State University (Penn State) to account for both energy cost savings and greenhouse gas (GHG) emissions reduction goals through strategic investments in energy conservation measures (ECMs) in campus buildings. Through an analysis of multiple years of investment in facility upgrades across the university, the impacts of ECMs of various types are characterized by building type. The standards and criteria for ECMs investments are also evaluated with the goal to develop a predictive tool to support decision making pertaining to an annual investment in a portfolio of ECMs that will maintain a trajectory to achieve both financial return on investment as well as GHG reduction goals.

This study is comprised of three main parts: analyzing the energy costs saving and GHG emissions reduction contribution of various building types in which ECMs were conducted, analyzing costs saving and GHG emissions reduction contribution of each ECM while considering the average annual investments made in them and estimating the impact of upgrading Penn State’s steam plants from firing a mixture of coal and natural gas to natural gas only on the GHG emissions.

These analyses help identify which types of buildings and ECMs would have larger savings and emissions reduction contributions. A calculator is also created to enable forecasting of costs saving and GHG emissions reduction of investment distribution strategy among ECMs. This study demonstrates that the calculator based on data from previous years will benefit decision makers in more wisely configuring the investment portfolio.

This paper fulfills an identical need to couple energy efficiency strategies coupled with the environmental impacts associated with different fossil fuel energy sources.

This study provides a comprehensive framework of adaptation in triadic business relationship settings in the service sector. The framework is based on the industrial network approach (see, e.g., Axelsson & Easton, 1992; Håkansson & Snehota, 1995a). The study describes how adaptations initiate, how they progress, and what the outcomes of these adaptations are. Furthermore, the framework takes into account how adaptations spread in triadic relationship settings. The empirical context is corporate travel management, which is a chain of activities where an industrial enterprise, and its preferred travel agency and service supplier partners combine their resources. The scientific philosophy, on which the knowledge creation is based, is realist ontology. Epistemologically, the study relies on constructionist processes and interpretation. Case studies with in-depth interviews are the main source of data.

Research demonstrates that individuals display relative thinking – the tendency to consider relative savings rather than just absolute savings in their decisions to search for a deal or purchase an item. This paper aims to review empirical and analytical literature on relative thinking, perceived search costs and price savings to propose and test a conceptual model of relative thinking.

Through two studies, the paper tests whether individuals display relative thinking when shopping across stores vs online and how they perceive search and time spent in pursuing savings. Both studies are adaptations of the classic jacket-and-calculator scenario study (Tversky and Kahneman, 1981).

Results show attenuation of the robust relative thinking phenomenon over the internet compared to shopping across stores. Individuals exhibit increased price sensitivity for both low and high relative savings conditions on the internet but demonstrate price sensitivity only in the high relative savings condition in the store shopping contexts. Diagnostic measures pertaining to the attractiveness of savings and the perceptions of search costs corroborate the support for relative thinking across stores but not over the internet.

These results lend weight to the central claim in this paper that the internet marks a new boundary condition for the relative thinking phenomenon in marketing literature. Theoretical and managerial implications of the findings, the limitations of the studies and future research opportunities are discussed.

A very important concern of physical distribution managers is deciding the location of warehouses (distribution centres or depots). It is, therefore, not surprising that this location problem has been receiving considerable research attention and indeed, some impact has been made in actual industrial warehouse location decisions. The interested reader is referred to the expository articles, which describe both the theoretical developments and some practical applications of the theory.

This study aims to provide an estimation of carbon dioxide (CO₂) emission abatement costs in China’s industry sector during the period of 2006-2010, and additionally provide an ex-post estimation of CO₂ abatement cost savings that would be realized if carbon emission permits trading among different industry sectors of 30 provinces in China during the same period were allowed, to answer the question that whether the industrial carbon emission abatement cost can (partially) be recovered from carbon emission trading in China.

The joint production framework associated with the environmental technology is utilized for formulating the models for estimating abatement costs and simulating emission permits trading scheme. Several data envelopment analysis-based models that could deal with both the desirable and undesirable outputs within the above framework are utilized for abatement cost saving estimation. The weak disposability assumption and variable returns to scale assumption are applied in the modelling.

In China’s industry sector, during 2006-2010, the estimated CO₂ emission abatement cost was 1,842 billion yuan, which accounts for 2.45 per cent of China’s total industrial output value; the emission abatement cost saving from emission permits trading would be 315 billion yuan, which accounts for 17.12 per cent of the emission opportunity abatement cost; and additional 1,065.95 million tonnes of CO₂ emission reductions would be realized from emission permits trading, and this accounts for 4.75 per cent of the total industrial CO₂ emissions.

The estimation is implemented at the regional level, i.e. the emission permits trading subjects are the whole industry sectors in different Chinese provinces, because of the data limitation in this study. Further estimation could be implemented at the enterprise level to provide a deeper insight into the abatement cost recovery from emission permits trading.

The estimation models and calculation process introduced in this study could be applied for evaluating the efficiency and effectiveness of pollutant emission permits trading schemes from the perspective that whether these market-based abatement policy instruments help to realize the potential abatement cost savings.

To the best of the authors’ knowledge, no study has provided the estimation of CO₂ emission abatement cost and the estimation of CO₂ abatement cost saving effect from emission permits trading for China’s industry sector. This study provides the first attempt to fill this research gap.

After salary and wages, facility and real estate expenditure are the largest cost items in the semi‐public sector. Especially, for long‐term care facilities, there is high‐saving potential from more efficient and effective use of property. The main purpose of this paper is an exploratory research study in order to analyse the operating costs of long‐term care facilities.

The survey is based on empirical data questionnaires, data generation and semi‐structured interviews at 18 long‐term care facilities in Tyrol, Austria carried out during Summer 2007. In order to determine the volume and to prioritize the cost drivers computer‐aided real‐estate benchmarking software was used, which was developed by the Institute of Real Estate Benchmarking at the University of Applied Sciences KufsteinTirol, Austria. Statistic analyses were conducted to investigate saving potential, determine the best case of the sample and submit recommendations to the decision makers.

The main findings are the investigation and visualization of saving potential of long‐term care facilities and identification of the volume and structure of the cost drivers and illuminated current best practices in effective building upkeep and operating costs of long‐term care facilities in Tyrol. Furthermore, the study reveals the immense saving potential in the costs of various services.

This survey is based on the operating costs of long‐term care facilities. Other running costs such as costs for healthcare personnel as well as quality indicators are not considered in this survey. Further research activities will be necessary regarding the identification of these cost drivers by the application of regression models.

Professional property management of long‐term care facilities will be shown to decrease the cost share in the healthcare sector. The results should help to establish cost benchmarking increasingly and develop it as a strategic planning tool in order to support management in the healthcare sector in the decision‐making process.

The paper presents a new measuring method, which allows an holistic view of three influencing factors, namely the amount of beds, occupancy and the space consumption, to investigate weak points in cost efficiency on one chart.

The purpose of this paper is to clarify agricultural services into five categories, including agricultural materials supply service, financial service, technical service, machinery service and processing and sales service, and to examine the effect of agricultural services on cost saving of rice production in China.

Based on a three-year panel data set covering 3,421 rice farmers in 12 Chinese provinces collected from the state rice industry experiment stations’ fixed watch points of China Agriculture Research System, a stochastic frontier model which takes the price vectors of input variables into cost function is developed by stochastic frontier analysis method in the study.

There is a deviation between the actual cost and the minimum cost on rice production in China due to the loss of cost efficiency, whose score is 0.7983 at the mean. Agricultural services can help improve cost efficiency, thus contributing to cost saving. Specifically, the effect of technical service on cost saving is the highest, followed by processing and sales service, machinery service, financial service and agricultural materials supply service.

The results of this paper are of great significance to the effectiveness and efficiency of the targeted agricultural services and indicate implications for policy improvement under the context of clear upward trend of agricultural production costs.

The demand for Saudi Arabian real (SAR) is very high in the pilgrimage (hajj) season while the authority, unfortunately, does not hedge the hajj funds. As such, the hajj funds are potentially exposed to exchange rate risk, which can impact the value of hajj funds and generate extra cost to the pilgrims. The purpose of this paper is to conduct simulations of Islamic hedging for pilgrimage funds to: mitigate and minimize exchange rate risk, identify and recommend the ideal time, amount and tenors of Islamic hedging for hajj funds, estimate cost saving by pursuing Islamic hedging and propose technical and general recommendations for the authority.

Forward transaction mechanism is adopted to compute Islamic forward between SAR and Rupiah (Indonesian currency) or IDR. Findings – based on simulations, the paper finds that: the longer the Islamic hedging tenors, the better is the result of Islamic hedging, the decreasing of IDR/USD is the right time to hedge the hajj funds and, on the other hand, the IDR/SAR appreciation is not the right time to hedge the hajj funds.

Based on simulations, the paper finds that: the longer the Islamic hedging tenors, the better is the result of Islamic hedging, the decreasing of IDR/USD is the right time to hedge the hajj funds and, on the other hand, the IDR/SAR appreciation is not the right time to hedge the hajj funds.

The research suggests the authority to (and not to) hedge the hajj fund, depending on economic conditions and market indicators. Even though the assessment is for the Indonesian case, other countries maintaining hajj funds might also learn from this paper.

To the best of author’s knowledge, this is the first paper in Indonesia that attempts to simulate the optimal hedging of hajj funds.

There is an unresolved paradox concerning electricity energy-saving behaviour. On one hand, there are many studies on energy-saving behaviours and on the other hand, recent research stresses that there exists large amount untapped potential in terms electricity energy-saving behaviours. Therefore, it becomes pertinent to revisit the construct of electricity energy-saving behaviours qualitatively to enlarge the spectrum of understanding. The purpose of this paper is to answer the research question why do not customers care about electricity energy-saving behaviours.

A qualitative study is undertaken in Western India using grounded theory methodology. The basic steps in the analysis of qualitative data consist of coding the data, combining the codes into broader categories and themes, and interpreting the results.

The study identifies seven categories of determinants of electricity energy-saving behaviours. Policy implications and limitations of the study are discussed along with areas of future research directions.

This is the first study to unearth the dimensions of electricity energy-saving behaviour.

Integrated project delivery (IPD) is highly recommended to be utilised with building information management (BIM), specifically with BIM level-3 implementation process. Extant literature highlights the financial management challenges facing the proposed integration. These challenges are mainly related to the IPD compensation and the conventional cost control approaches that are not consistent with IPD principles. As such, this paper presents an integration of several methods to support automating risk/reward sharing amongst project parties thus enhancing IPD core team members’ relationship.

The literature review was used to highlight the challenges that face the IPD-based cost management practices such as the risk sharing/reward sharing amongst IPD core team members and potential methods to bridge the revealed IPD gap. A framework was developed by integrating the activity-based costing (ABC) – as a method to analyse the cost structure – and earned value management (EVM) to develop mathematical models that can determine the three main IPD financial transactions (i.e. …) fairly. To demonstrate the applicability of the developed system, a real-life case study was used, in which, promising results were collected in regard to visualising the cost control data and understanding of the accumulative status of the project cost and schedule for team members.

A centralised cost management system (CCMS) for IPD is developed to enable the IPD cost structure as well as automating the risk-sharing/reward-sharing calculations. This system is linked with a web-based management system to display the output of proposed risk-sharing/reward-sharing models. Moreover, a novel grid is developed to show the project status graphically and to respect the diversity in core team members backgrounds. In addition, the case study showed that the proposed integration of different methods (ABC, EVM, BIM and web-based management system) is interoperable and applicable.

This research presents a comprehensive solution to the most revealed challenges in cost management practices in IPD implementation. The outcome of this research contributes to the body of knowledge through presenting new extensions of the EVM to be used with the IPD approach to calculate risk/reward. Moreover, the implementation of the proposed tools such as centralised cost management system (CCMS) and CCMS for IPD web system will enhance/foster the implementation of the IPD in conjunction with BIM process.
