Estimates show that close to 90% of the buildings we will need in 2050 are already built and occupied. The increase in the existing building stock has affected energy consumption thereby negatively impacting the environment. The purpose of this paper is to assess determinants of sustainable upgrade of existing buildings through the adoption and application of sustainable technologies. The study also ranks sustainable technologies adopted by the professionals who participated in the survey with an in-built case study.

As part of the overall methodology, a detailed literature review on the nature and characteristics of sustainable upgrade and the sustainable technologies adopted was undertaken. A survey questionnaire with an in-built case study was designed to examine all the sustainable technologies adopted to improve energy consumption in Australia. The survey was administered to sustainability consultants, architects, quantity surveyors, facility managers and engineers in Australia.

The results show a total of 24 technologies which are mostly adopted to improve energy consumption in existing buildings. A factor analysis shows the main components as: lighting and automation, heating, ventilation and air conditioning (HAVC) systems and equipment, envelope, renewable energy and passive technologies.

The findings bridge the gap in the literature on the adoption and application of sustainable technologies to upgrade existing buildings. The technologies can be adopted to reduce the excessive energy consumption patterns in existing buildings.

The Gulf Cooperation Council (GCC) of countries has some of the highest electricity consumptions and carbon dioxide emissions per capita in the world. This poses a direct challenge to the GCC government’s ability to meet their CO₂ reduction targets. In this review paper the current household electricity consumption situation in the GCC is reviewed.

Three scenarios for reducing energy consumption and CO₂ emissions are proposed and evaluated using strengths, weaknesses, opportunities and threats (SWOT) as well as the political, economic, social, technical, legal and environmental (PESTLE) frameworks.

The first scenario found that using solar Photovoltaic (PV) or hybrid solar PV and wind system to power household lighting could save significant amounts of energy, based on lighting making up between 8% to 30% of electricity consumption in GCC households. The second scenario considers replacement of conventional appliances with energy-efficient ones that use around 20% less energy. The third scenario looks at influencing consumer behavior towards sustainable energy consumption.

Pilot trials of these scenarios are recommended for a number of households. Then the results and feedback could be used to launch the schemes GCC-wide.

The proposed scenarios are designed to encourage responsible electricity consumption and production within households (SDG12).

All three proposals are found viable for policymakers to implement. However, to ensure successful implementation GCC Governments are recommended to review all the opportunities and challenges associated with these schemes as laid out in this paper.

The issue of energy efficiency is becoming increasingly prevalent globally due to factors such as the expansion of the population, economic growth and excessive consumption that is not sustainable in the long run. Additionally, healthcare facilities and hospitals are facing challenges as their operational costs continue to rise. The research aim is to develop strategic frameworks for managing green hospitals, towards energy efficiency and corporate governance in hospitals and healthcare facilities.

This research employs a qualitative case study approach, with a sample of ten hospitals examined through interviews with senior management, executives and healthcare facilities managers. Relevant data was also collected from literature and analysed through critical appraisal and content analysis. The research methodology is based on the use of grounded theory research methodologies to build theories from case studies.

The research developed three integrated conceptual strategic frameworks for managing hospitals and healthcare facilities towards energy efficiency, green hospital initiatives and corporate governance. The research also outlined the concepts of green hospitals and energy efficiency management systems and best practices based on the conclusions drawn from the investigated case studies.

The study is limited to the initiatives and experiences of the healthcare facilities studied in the Middle East and North Africa (MENA) region.

The research findings, conclusions, recommendations and proposed frameworks and concepts contribute significantly to the existing body of knowledge. This research also provides recommendations for hospital managers and policymakers on how to effectively implement and manage energy efficiency initiatives in healthcare facilities.

Marketing.

This case is oriented to undergraduate (BA) students taking courses in marketing strategy, branding, new product development and market research.

This case deals with the events surrounding branding and positioning of a compact fluorescent lamp (CFL) by a multinational company settled in Mexico. After working in a private–public partnership (PPP) that deployed millions of CFLs in the Mexican market, the company is now striving to understand customer repurchase behaviour. The company executives are struggling with product, technology, and distribution issues. Their primary task is to develop an appealing marketing strategy and a tactical plan in the context of reduced budget and sceptic customers.

This study's task is to enhance student's ability to perform functional marketing analysis; to frame issues according to a given business model to solve the problems that organizations face in developing innovative products; and to propose alternate courses of action and formulate competitive marketing strategies.

This paper aims to develop a multi-criteria decision framework (MCDF) for the selection of appropriate low carbon building (LCB) measures for office buildings in Hong Kong.

The research was carried out through a critical literature review and a case study with a low carbon office building project.

In total, 26 LCB measures were identified, under the five groups of building envelope, heating, ventilating and air conditioning system, lighting and elevators, renewable energy and appliances. Also identified were 16 decision criteria, centred on the implementation-related, economic, environmental and production-related aspects. The identified measures and criteria, coupled with the information and business processes of office building project delivery, formed the conceptual MCDF. The MCDF was also verified using an office building project.

The limitation of this research was the absence of the energy bill which could help to further verify the model in the case study.

The developed framework should add value to knowledge of the use of multi-criteria decision-making methods and support the design decision-making of selecting LCB measures for office building projects in Hong Kong. The findings should also inform LCB design in other hot and humid subtropical urban environments.

The purpose of this paper is to describe the effect of attitudes in promoting sustainable operations in hotels. The aim of this paper is to demonstrate the interaction between the users' behaviour and the way energy is consumed in Greek hotels in a long‐term period.

In total, two scenarios are developed, using the Long Range Energy Alternative Planning software (LEAP). Each scenario exhibits different findings proposing significant, but easy to apply alterations to hotels. The first one is the Business as Usual (BaU) scenario, and it is developed based on the current trends in energy use in hotels. The second is the Policy scenario, which is developed based on the existing legislative framework, Greek and EU. Through interviews with open‐ended questions, hoteliers' responses reveal their views and attitudes in energy initiatives, along with the level of information they have on the existing energy legislation – Greek and European – to reduce energy consumption in buildings.

This research project, aims at identifying the hoteliers' views in applying energy efficiency measures in their facilities. The BaU scenario displays the current energy consumption in hotels, without policy interventions. The Policy scenario displays the effectiveness of each proposed measure in all services offered in hotels. This analysis provides recommendations in order to improve the current energy framework.

This methodology provides the development of a model that combines the existing energy measures considering also the end‐users' behaviour. It shows the areas that need to change in order to reduce energy consumption in the whole population of Greek hotels. It is a process that could be applied easily in other countries, not only in Greece.

This paper is a generic research analysis. The data collection has been selected for the first time from the sample of hotels. This type of research has not been developed previously in Greek hotels, since attitudes, energy consumption and measures have not been combined previously, in order to promote sustainable operations in hotels.

The purpose of this paper is to suggest the usage of the project finance (PF) scheme as a suitable mechanism to fund energy efficiency projects at the urban scale and present its advantages and adoption barriers.

A case study is developed to renew the traffic lighting system of an Italian town via replacement of the old lamps with new light-emitting diode (LED) technology. Several partners are involved in the case project to construct a viable PF arrangement.

The case study presents the viability of the proposed PF scheme that provides for acceptable financial returns and bankability. However, it also shows that the need for short concession periods may call for a public contribution to the initial funding to make the project more attractive to private investors.

This case study is a useful guideline for governments and promoters to using the PF arrangement to fund energy efficiency investments in urban settings. It helps designing an appropriate PF scheme and understanding the advantages of PF to reduce risk and, consequently, increase the debt leverage and profitability of energy efficiency projects.

This paper contributes to bridging the gap about the lack of works addressing the implementation of the PF mechanism in the energy efficiency sector in urban areas. The importance of this paper is also associated with the shortage of traditional public finance faced by many cities that forces to seek for alternate forms of financing.

The purpose of this paper is to investigate the current market development of Energy Performance Contracting (EnPC) in Hong Kong and Taiwan, focussing on four key aspects: first, the potential building energy retrofits as an investment for future savings; second, the motivations for building owners toward the use of EnPC; third, the reasons for building owners not using EnPC; and fourth, the different approaches of Hong Kong and Taiwanese governments toward the promotion of EnPC.

A dual-questionnaire survey was conducted both in Hong Kong and Taiwan, where the same set of questionnaire was sent to the key personnel of the energy services companies (ESCOs) in both regions as identified from the latest member lists of representative trade associations, supplement with 11 structured interviews.

Apart from explainable differences, the results show the top rankings by the respondents of Hong Kong and Taiwan as follows: “Potential retrofit works” including lighting replacement with efficient fluorescent and light emitting diode lamps and improvement of air-con system. “EnPC Motivations” including owners’ lack of upfront capital and use of energy savings for other purposes may yield better returns; ESCOs’ provision of turnkey services. “Reasons not considering EnPC” including worry about its complexities; lack of familiarity with EnPC and long payback periods. As for promotional efforts for EnPC, the Taiwan government has taken more initiatives to foster its use both technically and financially.

This study identifies market-related motivators and deterrents as experienced by ESCOs in implementing EnPC projects in two developed Asian economies.

This study provides insightful information for the stakeholders about the latest market development of EnPC in Hong Kong and Taiwan.

The purpose of this paper is to quantify the potential levels of greenhouse gas (GHG) and cost savings from a set of households’ energy saving measures, considered as “everyday choices”.

Four areas of living were selected for the study: household electricity, space heating, transport and food consumption. The study used a quantitative research approach in which the impact of selected scenarios of an average Finnish household was assessed.

Findings suggest that GHG savings from behavioural change regarding household electricity remain marginal in comparison to savings gained from transportation related measures. Transportation also provides the most cost-efficient ways to decrease GHGs but not in all cases. Based on the results, the authors suggest that smart technologies, such as on-line, active feedback systems could have a major role in guiding household energy use. Also, given the high GHG savings from transport, the authors highlight the importance of providing infrastructure and services for clean mobility, and in designing well-functioning and compact cities enabling shorter travels.

The aim of our study was twofold – by analysing the case household’s choices, we obtained information on environmental and economic impacts, but in addition to this, the aim was to open discussion on the role of households in tackling climate change and how to support households in making sustainable choices. Although research regarding household energy behaviour is vast, so far very few studies have focused on both economic and environmental impacts of households’ everyday actions.
