The methodology presented in this report is developed to assist refurbishment projects in the early stages to establish a sustainable retrofit strategy. Through an analysis of the energy efficiency, life cycle carbon and cost of various retrofit measures, the method can give guidance on what measures should be pursued in a project and which ones should be avoided. Establishing a sustainable, evidence-based strategy early on is a key part of a successful retrofit and a sustainable future. The method is presented though a case study, based on an actual residential refurbishment project but it is appropriate for any building typology.
