    Decision support for selecting a shortlist of electricity-saving options: A modified SMAA approach
    (2013) Durbach, I N; Davis, S J
    This paper describes an application providing decision support for generating a shortlist of promising electricity-saving options for households in South Africa. The decision problem is characterised by constraints on time and other resources, and by substantial uncertainty around the preferences for energy-related attributes and the performance of alternatives on those attributes. We use a stochastic multi-criteria acceptability analysis model to incorporate preferential uncertainties, and adapt this for use with quantiles and other "simplified" formats for representing uncertain attribute evaluations

    Spend, save and splurge - the rebound effect of energy efficiency initiatives
    (University of Cape Town, 2008) Davis, S J
    Energy Efficiency (EE) and Demand Side Management (DSM) programs are being implemented throughout the world’s energy sectors, with the intention of managing the demand for energy services, improving energy security and reducing the externalities of electricity production. However, the rebound effect has meant that the actual savings in energy demand are often less than expected making these costly programs ineffective, or worse raising consumption. In this paper, we define the rebound effect of EE and DSM initiatives in the electricity sector, summarise the literature, and provide the foundation for investigating the extent and causes of rebound in the South African residential sector.
