Retrofit Designer
- Abbey Wood, South East London
- Permanent
- Full-time
- Develop retrofit design solutions in line with PAS2035:2023 requirements and client specifications, considering feasibility, resident comfort, and building performance outcomes.
- Interpret and analyse Retrofit Assessment data, including Condition Reports, ventilation appraisals, and Improvement Option Evaluations (IOE) to inform design decisions.
- Produce detailed design documentation covering proposed measures, specifications, ventilation strategies (Approved Document F compliance), airtightness strategies, and materials compatibility, with clear sequencing and installation guidance.
- Identify building constraints, risks, heritage considerations, and performance limitations, proposing appropriate mitigation measures.
- Undertake U-value calculations, thermal bridging analysis, and condensation risk assessments to support robust design outputs.
- Liaise with the Retrofit Coordinator to finalise Medium-Term Plans (MTP) and ensure designs are deliverable, practical, and aligned with programme budgets.
