Given the very low renewal rate of the building stock, the efforts to reduce energy demand must focus on the existing residential buildings. Even though awareness has been raised, the effect on energy efficiency is often neglected during the design phase of refurbishment projects. This paper discusses an integrated approach to energy-efficiency upgrades of residential building stock, by assessing the impact of retrofitted components in the early stages of the design. Firstly, the key building components of an integrated refurbishment are identified and various solutions are systematically organised into a “toolbox”. Moreover, a roadmap to refurbishment design was created. The proposed methodology, applied on case study buildings, resulted in improvement of the dwelling energy demand up to 80%. This approach recognises the diversity of each project, as well as the designer’s freedom to his decisions. It assists efficient choices, with respect to the specific requirements of each project. The toolbox information enables designers of refurbishment project to know in the early stages of the design the impact their choices will have.
