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.
