An artefact for improving the delivery of building energy retrofit project in South Africa

Purpose: The built environment is well known for carbon emission and its impact especially as it pertains to existing buildings. This has culminated in an increasing need for a retrofit of such buildings. This study details the development of an artefact for improving the delivery of energy retrofit projects therein to curb these impacts. Design/methodology/approach: The study utilized a mixed method research design for data collection. In achieving this, data was collected in three different phases; (1) a pilot study; (2) a juxtaposition of desktop case studies, live case studies, focus group discussion forum and an expert survey; and (3) a questionnaire survey for the validation of the emergent artefact. Accordingly, the quantitative data was analysed using descriptive statistics, whereas qualitative content analysis was deployed for qualitative data. Findings: The findings enabled an identification of the elements of a building energy retrofit project (BERP) such as project initiation, building assessment, detailed energy survey, technical analysis and implementation plans of energy measures, monitoring and verification. Also, it provided the challenges and enablers associated with successful BERP. This information was subsequently utilized in the development and validation of an artefact for delivering successful BERP. Summarily, a set of guidelines comprising of seven stages for managing successful BERPs were elucidated. Practical implications: The validated artefact provides an adaptive and innovative route for achieving sustainability in retrofit trade. Originality/value: The study conceptualizes an artefact for improving the delivery of BERPs.
