Background: This research is an on-going PhD research with primary aim of developing a decision support system for key stakeholders in sustainable retrofitted building projects. Delivering sustainable retrofitted building project in the construction industry has been characterised with a lot challenges especially with the inability of the key stakeholders to make an informed decision. Lack of informed decision is prevalent because the industry has neglected the need to manage project knowledge in sustainable retrofit activities. Construction industry is known to be knowledge intensive hence the need for knowledge management to be adopted and harnessed. Method: To achieve the aim, a mixed-method approach was adopted. This approach combines elements of qualitative and qualitative research approaches for the broad purposes of breadth and depth of understanding sustainable retrofit issues and capturing relevant knowledge. It also enabled the researchers to eliminate the respective weaknesses of both quantitative and qualitative approaches. The choice of case study as the research strategy was necessary in order to understand the dynamics and contemporary phenomenon present in the industry as regards to the research area. The case study involves the use of semi-structured interviews which targeted forty interviewees and documentary evidence (for qualitative approach) and, open-ended questionnaire (for quantitative approach) which targeted three hundred participants. Result, discussions and conclusions: The result of these was demonstrated in the positive feedback from the pilot study that has been conducted in furtherance to data collection. The participants of the pilot study are the key stakeholders in the industry and the academia. The analysis of the data when collected will be through computer-assisted (NVivo 10) for qualitative and SPSS for quantitative. Implication: The major limitation of the mixed-method approach in this research is the several months it will take to be achieved because multiple case organisations are involved, but it remains the best as established earlier in the literature.
