Exploiting BIM in energy efficient domestic retrofit: evaluation of benefits and barriers

Abstract: Energy efficient retrofit of the building stock is an important and contemporary issue in the built environment. Building Information Modelling (BIM) can offer a comprehensive and integrated platform for construction projects, as has been demonstrated in many large-scale projects, mostly in new buildings but sometimes also in retrofit projects. This research focuses on the potential of adopting BIM through a smaller scale activity of residential retrofit to achieve energy efficient housing. Although many strategies and technologies have been developed during the last decades, retrofit processes are still confronted by technical, economic and social challenges. This paper investigates how BIM may be integrated all the way through the residential retrofit process and how new digital technology can be engaged. The potential strengths and weaknesses of BIM implementation in retrofitting are identified. This paper is part of an on-going research study and the outcomes from this research will be used to develop a framework which enables informed decisions to be made in retrofitting schemes, and which utilises BIM to support efficient and effective design and construction processes and informed decision making in all stages of retrofitting projects improving the energy efficiency of the existing housing stock.
