Research Document

The Thermal Insulation Association of South Africa (TIASA) is supporting government measures to promote energy efficiency in South African buildings. The research document titled: ‘New standards of thermal design to provide comfort and energy efficiency in South African housing’, has been adopted by TIASA, and details an objective basis for a standard. The S.A.N.S. 283 titled: ‘Energy efficiency for naturally ventilated buildings’ has as its premise, the same assumptions and methodologies as the research document. The provision of comfort in all housing in South Africa, including the problematic 30/36 m2 subsidy house – can be a reality with the proposals.

Climatic Zoning

Building climatic zoning is a prerequisite for implementing building energy efficiency technology, which can help code makers and architects have an accurate understanding of the local climatic conditions. It takes the extreme monthly average temperature as the zoning index in the existing climatic zoning of rural areas in China. There will be unreasonable design phenomena of insufficient or excessive thermal insulation for a building envelope in rural areas. Aiming at the above problems, this paper modifies the current zoning. This research established the cooling and heating degree-day indexes HDD14 and CDD30 based on the thermal comfort characteristics of rural occupants and used the threshold method to subdivide rural areas into eight sub-zones. The results show that the problem of insufficient or excessive thermal insulation in rural areas can be effectively solved by replacing the extreme monthly average temperature index with the degree day index and the annual cumulative building load can be reduced by 6.4% on average without increasing the insulation cost. After more detailed zoning, the variance within the group is reduced and it accurately describes climate diversity, which is conducive to implementing climate-responsive energy-saving design in each subzone. Practical application: The major purpose of this paper is to solve the problem of unreasonable climate zone boundaries specified in the existing Design Standard for Energy Efficiency of Rural Residential Buildings. The existing zoning has led to conflicts between the actual heating demand and the building envelope thermal parameter limits specified in the standard. This work redefines the boundaries of the existing map using more up-to-date weather data to provide the right guidance for architectural designers.

PurposeGreen building is a relatively new concept with limited applications in property development in South Africa. The objectives of this study are therefore threefold: identify key green building principles considered by property developers, establish the benefits of implementing the principles and determine the barriers to its applications.Design/methodology/approachThe study adopted a case study of two Green Star South Africa (SA)-certified buildings in Sandton, Johannesburg. These are Alexander Forbes building, and Ernst & Young Eris Towers. The two certified buildings were purposefully selected because of the insightful information they provide regarding application of green building principles. The main themes investigated in the cases are environmental awareness, green building principles applications, as well as benefits and barriers of green building. A total of six interviewees from the contractors', property developers', environmental/green building consultants' and sustainability consultants' organizations who were involved in the implementation of green building principles in the two cases provided the qualitative data for the study. The qualitative data were supplemented with data relating to the two case studies obtained from the ‘Earth Works for a Sustainable Built Environment’. The interviews were arranged over a period of two months, and each interview took between 20 and 30 minutes. Analysis of the data was done through a phenomenological interpretation of the qualitative opinions expressed by the interviewees.FindingsKey green building principles comprising energy efficiency, water efficiency, resource efficiency, occupants' health and well-being and sustainable site development were implemented in the two cases. The fact that the buildings were rated 4-star enabled inference to be drawn that the implementation of the principles was less than 60 per cent. Energy efficiency of 35 per cent indicated in Case I suggests that the level is consistent with the South African green building standard of 25 per cent to 50 per cent. However, the energy and water efficiency assessment of the building were based on projections rather than on ongoing monitoring and evaluation of the buildings' performance. Moreover, perceived saving in operational cost was identified as dominant driver to green building principles implementation. Conversely, lack of government incentives and absence of reliable benchmarking data regarding performance of green buildings were major barriers to its full implementation.Practical implicationsThe findings of this study provide important implications to the developers and government on the application of green building principles. In the first place, the evidence that initial high cost premium could be off settled by long- term saving on operational costs as a result of use of local materials, energy and water savings as well as use of recycled material, as implemented in the two case projects, would improve investment decision in green building by developers. The understanding of the drivers and barriers to implementation of green building principles also has implications for guiding government policies and programmes towards green building.Originality/valueThe significance of this study stems from the fact that limited studies, especially in the South African context, have indicated the drivers and barriers to the implementation of green building principles. The case study approach adopted gave a novelty to the study by providing hands-on information from the stakeholders who were known to have played specific roles in the application of green building. The findings indicated that initial high cost premium was not a consideration in developers' choice of green building which justifies the possibility of a costlier product when factors such as environmental sustainability benefit is considered to be ultimate. The study thus suggests further research involving larger cases on energy efficiency, water efficiency and costs of green buildings compared to the conventional type to bring the findings to a broader perspective and assist to benchmark data for green building assessment.

Tax Deduction

The South African energy crisis harms the economy. Tax incentives are intended to help, but rules for incentives must be understood by all stakeholders for taxpayers to be encouraged to invest. Section 12L (S12L) is relatively new legislation that allows a tax deduction for verified year-on-year energy efficiency savings in South Africa. Concurrent benefits are excluded from this tax incentive, to prevent a double reward for the same activity. Although the prevention of double benefits is commonly addressed in the field of measurement and verification (M&V), non-technical guidelines are not available. This is a critical shortcoming since multiple professions (tax, audit and legal) need to understand the technical M&V requirements of S12L. This study reviews the current legislation and interpretations of concurrent benefits in terms of S12L. It shows that multiple energy-related incentives are utilised by industries and that, therefore, it must be determined if different programmes overlap, so as to create concurrent benefits with S12L. It is then critical to correctly apply M&V practice to ensure exclusion of concurrent benefits. This study also provides a simplified methodology to evaluate concurrency, based on the S12L regulatory requirements and standard M&V methods. Three case studies show how concurrency can occur and how M&V practice is applied to exclude double benefits. The test for concurrency is shown to reduce to the following question: Is the same energy saving funded twice? The tests must be done to ensure no double benefit occurs.

Reducing Energy

There are different ways of measuring energy efficiency. Although there is no generally agreed definition of the concept, it should, however, always be approached according to particular circumstances and contexts. As such, technological, operational, performance and equipment efficiencies should be taken into consideration. Generally, energy utilisation in most sectors of the South African economy is inefficient. This requires more energy needs to be generated in order to cater for losses. An increase in generation causes environmental problems at global, regional and local levels. A review of literature on energy efficiency was undertaken and a gap identified between legislation and efficiency in the agricultural sector. This article seeks to suggest ways of implementing an energy legislation in this sector in South Africa. Such implementation will address concerns in terms of harnessing, generating and utilising energy in different sectors in South Africa. Legislation is vital in reducing energy consumption in the agricultural sector. It also ensures efficient use of energy and the maintenance of current levels of production.

Background: South Africa is faced with a significant challenge of securing the supply of electricity as well as reducing its greenhouse gas emissions. The implementation of energy efficiency (EE) and renewable energy (RE) measures by energy consumers, especially businesses, is becoming increasingly important and a number of tax incentives have been introduced to promote EE and RE. Objective: The objective of this preliminary study was to determine the role that the available tax incentives play in the decision making of South African businesses regarding investment in RE or EE projects. Aim: To determine this role, the largest South African businesses were selected from the Johannesburg Stock Exchange Top 40 Index. Method: The study contained both empirical and non-empirical elements. A literature review was conducted to determine the role of tax incentives globally, while questionnaires were distributed to determine the role in South Africa. Results: Findings highlighted that, while tax incentives do play a role in decision making, various other non-tax factors drive South African businesses’ decisions to invest in EE and/or RE projects. These businesses do not perceive the available tax incentives as effective, nor do they regard them as sufficiently motivating for businesses to change their environmental behaviour. They also feel that the government should reduce the burden of complying with the requirements of Section 12L (the EE allowance). Conclusion: Improving the available RE and EE tax incentives in South Africa might result in more businesses considering the implementation of RE or EE projects. It is therefore recommended that the available tax incentives are expanded and/or the qualifying criteria simplified.

This paper describes the design process followed by Westinghouse Electric South Africa for the insertion of hot internals into the Reactivity Control System (RCS) and Reserve Shutdown System (RSS) Units Under Test (UUTs) at the Helium Test Facility (HTF) at Pelindaba, South Africa. The aim of the UUTs is to allow the validation of the high temperature operation of the RCS and RSS systems for implementation into the proposed Demonstration Power Plant of the PBMR. The units use electrical heaters to obtain pebble-bed reactor thermal conditions for both the control rods and small absorber spheres (SAS) under a pressurized helium environment. Design challenges include providing for strength under elevated temperatures (900°C maximum); pressure boundary integrity (9MPa maximum); separation of different volumes (representing core barrel, reactor citadel and other Reactor Pressure Vessel (RPV) volumes); thermal protection of carbon steel vessels by using thermal insulation; allowing for diverse thermal expansion coefficients of different materials; allowing for depressurization events within the insulation and internals; having access for temperature, pressure, stress and proximity sensors and electrical wiring through high pressure penetrations; and provision for assembly of the hot internals both on and off-site. Several thermal analyses using Computational Fluid Dynamics (CFD) were performed to evaluate both worst-case and operational conditions of the UUTs. Factors that were considered include thermal insulation properties, heat transfer modes (internal radiation, external radiation and natural convection, forced internal convection for cooling) and operating pressure (ranging from 1 to 9MPa). The thermal design uses elements originally proposed for hot gas duct design. The results obtained show that the proposed design satisfies ASME VIII requirements of the pressure boundary and that all challenges are successfully met.

Realistic Conflict Theory

Many scholars and South African politicians characterize the widespread anti-foreigner sentiment and violence in South Africa as dislike against migrants and refugees of African origin which they named ‘Afro-phobia’. Drawing on online newspaper reports and academic sources, this paper rejects the Afro-phobia thesis and argues that other non-African migrants such as Asians (Pakistanis, Indians, Bangladeshis and Chinese) are also on the receiving end of xenophobia in post-apartheid South Africa. I contend that any ‘outsider’ (White, Asian or Black African) who lives and trades in South African townships and informal settlements is scapegoated and attacked. I term this phenomenon ‘colour-blind xenophobia’. By proposing this analytical framework and integrating two theoretical perspectives — proximity-based ‘Realistic Conflict Theory (RCT)’ and Neocosmos’ exclusivist citizenship model — I contend that xenophobia in South Africa targets those who are in close proximity to disadvantaged Black South Africans and who are deemed outsiders (e.g., Asian, African even White residents and traders) and reject arguments that describe xenophobia in South Africa as targeting Black African refugees and migrants.

Much of the existing evidence for the healthy immigrant advantage comes from developed countries. We investigate whether an immigrant health advantage exists in South Africa, an important emerging economy.  Using the 2001 South African Census, this study examines differences in child mortality between native-born South African and immigrant blacks.  We find that accounting for region of origin is critical: immigrants from southern Africa are more likely to experience higher lifetime child mortality compared to the native-born population.  Further, immigrants from outside of southern Africa are less likely than both groups to experience child deaths.  Finally, in contrast to patterns observed in developed countries, we detect a strong relationship between schooling and child mortality among black immigrants.

The paper addresses the question of reparation in post-apartheid South Africa. The central hypothesis of the paper is that in South Africa current traumas or losses, such as the 2008 xenophobic attacks, may activate a ‘shared unconscious phantasy’ of irreparable damage inflicted by apartheid on the collective psyche of the South African nation which could block constructive engagement and healing. A brief couple therapy intervention by a white therapist with a black couple is used as a ‘microcosm’ to explore this question. The impact of an extreme current loss, when earlier losses have been sustained, is explored. Additionally, the impact of racial difference on the transference and countertransference between the therapist and the couple is explored to illustrate factors complicating the productive grieving and working through of the depressive position towards reparation.

The Moment

‘The Final “Thank You”’ uses the work of Jacques Derrida and Friedrich Nietzsche to think the occasion of the 1995 rugby World Cup, hosted by the newly democratic South Africa. This paper deploys Nietzsche's Zarathustra to critique how a figure such as Nelson Mandela is understood as a ‘Superman’ or an ‘Overhuman’ in the moment of political transition. The philosophical focus of the paper, however, turns on the ‘thank yous’ exchanged by the white South African rugby captain, François Pienaar, and the black president at the event of the Springbok victory. It is the value, and the proximity and negation, of the ‘thank yous’ – the relation of one to the other – that constitutes the core of the article. 1
