Sustainability has been the latest value added service in the facility management field. However, the practice of sustainability in the facility management field is not well recognized and understood by the facility management team. As a result, building sector account to be the largest source of greenhouse gas emissions around the world. In fact, there is a strong business case for green building, yet green buildings represent the next phase of buildings. Since, the majority of the existing stock of buildings is not sustainably built and as it is not practically viable to demolish all the existing buildings, hence, one alternate solution is green retrofitting. However, the responses for green retrofitting are at very low rate. This paper reports the need to green retrofitting, reasons behind the limited number of green retrofitting implementation, and finally, a critical review of the existing body of knowledge on green retrofitting has been conducted. It is found that there has been no research conducted till to date on identifying the success factors for successful green retrofitting implementation.
