    Real Estateā€™s value is unquestioned in terms of its measure financially and in economics. But there are forms and areas of value that do not lend themselves to easy or obvious modes of measurement and whilst these may be appreciated, they are not easily formally assessed or measured. This paper looks into the ā€˜tapestryā€™ of real estate value, recognizing that tapestries comprise multiple threads that are woven together to reveal a pattern or picture that can only be appreciated when the observer takes a step back and considers the contribution made by these multiple threads.The paper is conceptual and draws on both existing theories and cases. These are linked via the use of the ā€˜triple bottom lineā€™ approach to the recording of areas of value: economic, social and environmental. The paper considers the concept of value and the definition of real estate and, from weaving together the various concepts of value and illustrations of cases that illustrate aspects of the variety of value creation and destruction, seeks to reveal a rich, diverse and underappreciated world of real estate value.The paperā€™s conclusion reflects on the need to bring different views and expertise together and notes the creation of a new academically created forum that is being opened to further explore and understand better these many and varied areas of value that are in and from real estate

    The report assesses the progress made on renewable energy deployment for the solar and wind technologies over the last 12 years in South Africa. First the report assesses the potential contribution solar water heaters (SWHs), concentrating solar power (CSP), large-scale photovoltaic (PV) farms and wind technology can bring to South Africaā€™s energy demand by 2030. It highlights what the mid-term potential for each is by 2030 and compares this with the deployment of each over the past 12 years. From this a renewable energy policy effectiveness value is calculated based on the method developed in the Deploying Renewables Report (IEA, 2008a) and this is critically assessed. Finally, the report assesses the factors involved in renewable energy deployment, or the lack thereof, in South Africa and discusses recent developments in the field. The compilation of this paper was based on desktop reviews; data interpretation from multiple sources; expert opinion of the authors and peer reviewers; and interviews with experts in the field. A number of interviews were conducted at the ISES International Solar Energy Society Conference in October 2009 and the Energy 2010 Indaba in February 2010. The data used in this report to formulate the projections is from a number of sources and has been independently reviewed

    As part of Climate Strategies ā€˜International Support for Domestic Climate Policiesā€™ project this paper assesses the large-scale rollout of CSP in South Africa. Described as a Nationally Appropriate Mitigation Action (NAMA), the scale of CSP deployment is determined, and the amount of greenhouse gas emissions saved and incremental investment costs are estimated in line with the modelling outcomes of the Long-Term Mitigation Scenarios (LTMS) for South Africa (Chapter 2). Based on a stakeholder workshop held in May 2009 the drivers in support of the rollout of CSP are described, in particular the recently established Renewable Energy Feed-In Tariff (REFIT), and three major barriers relating to technology, regulation and infrastructure are highlighted (Chapter 3). The paper further assesses options of international support in light of the climate change negotiations to overcome the barriers identified (Chapter 4), and lastly, it assesses indicators that may be successful in monitoring the large-scale rollout of CSP (Chapter 5). In this study we define the ā€˜large-scaleā€™ rollout of CSP in line with the more optimistic ā€˜renewables extended with learningā€™ projection modelled in the LTMS of South Africa, as depicted in the figure below. The rollout is characterised by three phases: during the initial ā€˜Startā€™ phase, from 2010 to 2015, 2 GW of CSP capacity is constructed; the end of the ā€˜Scaleā€“upā€™ phase (2030) results in a 24 GW CSP capacity; and by the completion of the ā€˜Rolloutā€™ phase (2050) 100GW of CSP capacity should be established. This could result in 3,850 Mt CO2-eq saved over the period 2010-2050 and would require an incremental cost of R 4.7-13 billion per year if CSP technologies experience learning rates of 15 to 20% per year, and less (R 3.6-4.6 billion per year) if the country manages to create a local supply of CSP components. Post-2030, during the ā€˜Rolloutā€™ phase cost savings are expected to be achieved in South African electricity generation system. Before then the cost to the electricity system is estimate at R2.5 billion for 2010-2015, R 8 billion for 2016-2020 and R23 billion for 2021-2030 above the baseline projection. The rollout could result in approximately 3,800 Mt CO2-eq saved over the period 2010-2050 and the build programme is estimated to require incremental investment costs of R 4-13 billion per year if CSP technologies experience learning rates of 15 to 20% per year, and less ā€“ R 2-4.3 billion per year ā€“ if the country manages to create a local supply of CSP components

    South Africa's renewable energy policy roadmaps

    Get PDF
    South Africaā€™s renewable energy policy to date has largely been driven by a 10,000 GWh target by 2013 and renewable energy project subsidies offered through the REFSO. In 2009 a REFIT was published, which has resulted in a great interest by IPPs to develop renewable energy projects in South Africa. Nonetheless, under existing renewable energy policy few renewable energy projects for electricity generation have been deployed. SWHs have seen some market growth in 2008 and 2009 largely facilitated by a SWH subsidy and increased energy awareness due to nation-wide electricity blackouts in 2008

    Piezoelectric-based apparatus for strain tuning

    Get PDF
    We report the design and construction of piezoelectric-based apparatus for applying continuously tuneable compressive and tensile strains to test samples. It can be used across a wide temperature range, including cryogenic temperatures. The achievable strain is large, so far up to 0.23% at cryogenic temperatures. The apparatus is compact and compatible with a wide variety of experimental probes. In addition, we present a method for mounting high-aspect-ratio samples in order to achieve high strain homogeneity.Comment: 8 pages, 8 figure

    External cost of electricity generation: contribution to the Integrated Resource Plan 2 for Electricity

    Get PDF
    The international studies on energy externalities and the local studies in South Africa suggest that the high impact areas for power generation are impacts of climate change and health impacts of outdoor air pollution. Climate change impacts are by far the greatest. The health costs due to outdoor air pollution are considered quite low based on national studies, though these may be underestimated. Damage cost from acid mine drainage is also thought to be significant, and could be substantially higher than reported here. External costs of electricity generation are a necessary factor in modelling the IRP 2. To be consistent, external costs must be added to the modellerā€™s reference case and to all policy cases or scenarios. In the multiple criteria decision-making process, the external costs should be reported as a distinct criterion. The weighting of this criterion relative to others (cost, carbon, and access) should be discussed with stakeholders. Although the external cost presented here are appropriate for input into the IRP 2, an extensive national review must be completed for future IRPs. Furthermore, the Integrated Energy Plan (IEP) should take additional factors into account: health impacts of indoor air pollution (important in poor households, as well as industry); noise from transport, and other poverty-related issues such as wealth impacts of paraffin fires and burns, and social costs of fuel wood scarcity

    Project capabilities for operational outcomes in inter-organisational settings: the case of London Heathrow Terminal 2

    Get PDF
    Project and strategic management scholarship recognises the importance of project capabilities that allow firms to deliver projects. Although work on project capabilities is a fast-growing line of inquiry, little is still known about how clients assemble project capabilities to achieve operational outcomes in inter-organisational settings. This study seeks to apply theoretical work on project capabilities to the domain of infrastructure project delivery in order to understand how the assembly of project capabilities in temporary inter-organisational settings contributes to the delivery of operational outcomes. The empirical enquiry takes place in the context of the delivery of London Heathrow Terminal 2. Through an inductive theory building approach drawing upon semi-structured interviews with client-side project leadership, internal documents, publicly available data and ongoing engagement with the field, we identified three key capability-enabling mechanisms that help explain the genesis of project capabilities in inter-organisational settings: (1) reconfiguring project capabilities, (2) adapting project capabilities and (3) maintaining project capabilities. We discuss and expand these findings by engaging with theoretical ideas from project studies, and mainstream strategy, organisation, and management research to induce a dynamic model that can be helpful to guide future research, policy and management practices relating to the client side management of project capabilities
