    The emergence of green building practices : case study of Stellenbosch
    (Stellenbosch : Stellenbosch University, 2013-03) Slabbert, Gennae; Donaldson, R.; Stellenbosch University. Faculty of Arts and Social Sciences. Dept. of Geography and Environmental Studies.
    ENGLISH ABSTRACT: The aim of the study was to determine the application of green building practices in Stellenbosch. In order to achieve this aim certain objectives had to be met. The first objective was to retrieve national and international literature on green building initiatives. Six main sections were discussed in the literature namely, climate change and the environment, the built environment, the concept of sustainability in cities and buildings, green building designs and practices, green buildings, green building councils and the different green rating systems, with a specific focus on the Green Star SA rating tool. The second objective was to discuss three case scenarios in Stellenbosch that practice green initiatives. The case scenarios selected are Distell Group Limited, Spier wine estate and the new Remgro head office Millenia park. Buildings in Stellenbosch selected by means of probability sampling. A total of 35% of all commercially zoned buildings in the Stellenbosch core were selected to participate in the sample. The land zoning maps from the Stellenbosch municipality was obtained and relevant buildings were sampled. Nine of the sampled buildings were heritage buildings (older than sixty years) and seventeen were buildings from the modernist era (younger than sixty years). Nine architect companies in Stellenbosch were also sampled. The respondents were determined by means of haphazard sampling. The third objective was to design two questionnaires, one for building owners and another for architects. The first questionnaire developed for building owners was divided into two sections. The first section determined what green practices owners are incorporating into their office buildings. These green practices developed in the questionnaire focused on the use of natural light in the buildings, LED lights, indoor ventilation, recycling methods, water saving methods, energy saving methods and whether management plans exist to monitor and evaluate the buildings energy usage. The second section focused on the perception of the building owners. The respondents had to rate the importance of the above mentioned green initiatives on a scale of one 1 (being not at all) to 5 (being very important). The fourth objective was to develop a questionnaire for architects. The questionnaire determined whether green designs are incorporated by architects and if there is a greater demand for green designs by clients. The findings of the study revealed that respondents find natural light and air quality to be the most important aspects in an office. Recycling is applied by 93% of respondents. Less than 10% of respondents have installed solar panels, HAVC systems, rain water harvesting or other water management systems. Architects find that there has been an increase in the demand for green designs, but that there is a lack of knowledge of green initiatives by building practitioners. The main recommendations of the study are that the concept of green development be broadened into other spheres apart from planners. Education and training of green building must be available to all building owners and practitioners. Sustainable materials should be more accessible to building practitioners and these materials should be made available locally. Finally more buildings should be refurbished or renovated rather than be demolished to prevent waste and secure open spaces.
