Revalidating vernacular techniques for a sustainable built environment by way of selected examples in the Eastern Cape

[摘要] English: Contemporary design and construction methods often entail large amounts of wastage, high construction costs, high energy consumption for heating and cooling, and thus a large carbon footprint, which limits their sustainability. While South Africa's granting of much-needed houses to the indigent population is noteworthy, the quality of these houses sometimes leaves much to be desired. In addition, the cultural identity of the inhabitants of these houses is being lost. The purpose of this study is to determine if vernacular architecture and building techniques could be a possible solution to the above-mentioned problems concerning contemporary design in the Eastern Cape. Five case studies were conducted for this research. The first involved a perception analysis �?through a questionnaire �?of inhabitants of vernacular and contemporary homes in uMasizakhe, Graaff-Reinet. The next two case studies involved documenting the now-demolished Luxolweni community on the outskirts of Hofmeyr and three now-demolished rondavels surrounding Hofmeyr. The last two case studies are of recently-built contemporary designs. The first is a vernacular building in rural Centane and the second is a building steeped in innovations for sustainability in East London. The main results from the study revealed that the material properties of vernacular buildings are in many ways superior to their contemporary counterparts (these houses are cooler in summer and warmer in winter), vernacular homes are considered socio-culturally acceptable by their inhabitants, vernacular techniques can be successfully incorporated into contemporary architecture and that innovations can be incorporated within vernacular architecture for longevity. It was concluded that vernacular architecture has the potential to improve human settlements and the sustainability of the built environment, as well as strengthening the cultural identity of the local populace. This research is relevant in a country where buildings are often unsustainable and housing is lacking, as it offers a potential solution to these problems.
