It is no secret that retrofitting an existing structure to a high standard is more challenging than building a new one. In part, retrofitting is challenging because of the diversity of obstacles faced by designers when considering insulation, airtightness, and thermal bridge mitigation strategies – every house is different. With unprecedented retrofit targets outlined by both Irish and UK governments, it is important to develop scalable retrofit approaches, that can be applied to a diverse building stock – not quite a one size fits all, but one size fits many.
This residential project carried out by Andrew Simmonds and Tim Hulse in rural Wales demonstrates that modernization at scale can be simplified and successfully completed. Andrew is the CEO of the Association of Environment Conscious Building (AECB) and Partner at Simmonds Mills Architects, while Tim is a Passivhaus Champion at EcoVert Solutions. Both Andrew and Tim have a passion for energy-efficient building, having worked on numerous new build and retrofit Passivhaus projects previously.
