Energy consultants calculating sustainability for residential buildings

Purpose This paper aims to investigate the role of a particular energy calculator in enhancing the energy efficiency of existing homes by asking how this calculator was developed and how it is domesticated by craftspeople working as energy consultants. Design/methodology/approach The study is based on qualitative interviews with users and producers of the energy calculator (n = 22), as well as participation in energy consultation training. Findings The paper finds that, in the energy calculator, there is a striking lack of connection between the domestication and script because of lack of energy consultants’ involvement in the design and implementation process. Practical implications The enrolment of energy consultants as energy calculator users earlier in and throughout the design process could be valuable in making the transition to an energy-efficient and environmentally friendly building sector. Social implications The paper argues for recognition of the role of energy consultants, especially craftspeople, as participants in the design process for tools of governance. This is a call to acknowledge the value of particular skills and experiences possessed by craftspeople doing home consultation. Originality/value By understanding the intricate developer–user synchronicity in tools developed for upgrading the building sector, energy mitigation can be made more effective.
