Case Studies

Tai Tarian’s solar PV rollout demonstrates how this ambition can be translated into practice. It shows how an organisation can move from relatively small programmes to structured, high-volume delivery, while…

Delivered across several communities in Gwynedd, Adra’s Fabric First Retrofit Project demonstrates how fabric led decarbonisation can simultaneously reduce carbon emissions, ease fuel poverty, improve resident wellbeing, and strengthen local…

Denbighshire County Council used ORP 1 funding to deliver a test-and-learn retrofit programme in 54 homes in Meliden, Prestatyn.

Solar PV complete with battery storage installed to 22 rented properties in two rural locations

The Llwynon Sheltered Complex in Crynant transitioned from a failed communal gas system to green energy solutions—installing Dimplex Quantum heaters, Solar PV, and Santon cylinders—to improve EPC ratings and reduce…

Tai Tarian installed iOpt environmental monitoring sensors in 534 properties with photovoltaic systems as part of the Optimised Retrofit Programme (ORP 3.3).

Properties in the Green Voids programme had multiple improvement measures including EWI/ IWI, floor insulation, new windows, improved ventilation, heating PV and battery storage.

The aim of this project was to improve the energy efficiency of the homes on the Coed Leee estate, cut fuel bills for residents and reduce carbon emissions

Gwynfaen is a transformative residential development in Penyrheol, Swansea, led by Pobl Group in partnership with Swansea Council and supported by the Welsh Government’s Innovative Housing Programme (IHP).

A property housing vulnerable residents was externally insulated after removing concrete render, resolving severe cold and condensation issues without needing to relocate occupants.

Solar PV systems were installed on 61 homes—57 with battery storage and 4 without—by Welsh firm GB-Sol, with iOPT monitoring ensuring compliance with environmental sensor requirements.

Elm Avenue consists of four 1956-built, non-traditional Gregory-type flats with uninsulated concrete walls and slab floors. The property was selected for a fabric-first retrofit under the ORP scheme to address…

A thermal and mechanical retrofit, and improvements to existing 1970’s block of 23 flats.

This project involved the installation of Intelligent Energy Systems and Solar PV systems with battery storage to 60 properties across 16 local authority areas.
