PROJECT OVERVIEW
Target Green was appointed by Joyner Group, on behalf of Newport City Homes, to deliver PAS 2035-compliant retrofit services across 52 social housing properties in Newport, Wales. The project was funded through the Optimised Retrofit Programme (ORP) and focused on improving the energy performance, comfort and long-term resilience of homes across 22 different archetypes.
HOW WE GOT STARTED
Target Green was brought in to provide full PAS 2035 services including Retrofit Assessment, Coordination, and Design. We also supported planning processes where required. From the outset, the project required a highly tailored approach, as the properties varied significantly in type, condition, and construction. A key goal was to create a consistent level of performance across the estate while maintaining visual character and ensuring all works complied with PAS 2035:2019 and relevant Building Regulations (Approved Documents C, F, and L).
CHALLENGES & SOLUTIONS
Severe Wind-Driven Rain Exposure
The site is located in a ‘very severe’ wind-driven rain zone, which required careful consideration in the detailing and product selection. We specified robust mineral fibre EWI systems with enhanced sealants, breathable finishes, and extended roof overhangs to protect the building envelope.
Resident Engagement
As with all retrofit projects, resident engagement was critical. With multiple properties and varying access needs, we worked closely with housing officers and residents to provide clear communication, reassurance around health and safety, and minimise disruption throughout the works.
Fabric First Improvements
Cavity Wall Measures: Failed insulation was extracted and
replaced where required; wall tie replacement was carried out
as needed.
External Wall Insulation (EWI): Installed to cavity walls using
mineral fibre systems with U-values of 0.3 W/m²K. Render
finishes were selected to align with existing façades.
Roofing & Insulation: Roof tiles were replaced and
existing loft insulation was topped up to improve thermal
performance.
Windows and Doors: High-performance replacements
improved airtightness, thermal efficiency and safety.
Thermal Bridging: Junctions around canopies and external
elements were addressed with insulation measures.
FINAL OUTCOME
By adopting a fabric-first approach, the project laid the groundwork for sustainable, long-term energy
performance improvements while enhancing resident comfort and building durability.
Newport City Homes praised the project’s structured delivery, timely execution and measurable outcomes for tenants.
These works now form the foundation for further decarbonisation measures in future funding phases.
