Domestic Installation of the Year Winner: Panasonic for the Together Housing Project


As part of its ‘We Can - Go Green Together’ initiative, social housing provider Together Housing Group (THG) partnered with Panasonic to install air-to- water heat pumps in over 1,200 properties across the Northwest of England. The Panasonic J Series Aquarea heat pumps have been retrofitted to replace traditional gas boilers in more than 700 of these homes, significantly enhancing energy efficiency and potentially reducing energy consumption by over 50%. Panasonic collaborated with


Together Housing to educate residents through an online portal that provides guidebooks on understanding energy bills, meter readings, available tariffs, smart meters, selecting heating programmes, and financial support options. Additionally, all residents were offered the Panasonic Aquarea Smart Cloud thermostat and programmer for easy control of their heating systems.


This project was undertaken as part of the government’s Social Housing Decarbonisation fund and Together Housing’s commitment to installing 31,000 heat pumps by 2035. Both


Judge’s comment: “One cannot help but be very impressed with this entry. The scale of the project is impressive as is the householder engagement plan.”


Panasonic and Together Housing are leading efforts to create more environmentally friendly communities across the North of England. The teams from THG and


Panasonic collaborated to design an economically viable development model, enabling upgrades to as many homes as possible while maintaining high standards. All case study


properties have demonstrated significant reductions in kWh usage, with one heat pump delivering over £250 in real-time savings within the first four months.


This initiative directly supports


households facing fuel poverty and improves the Energy Performance Certificate (EPC) ratings of properties to or above the required ‘C’ standard.


Commercial Installation of the Year Winner: EVO Energy for Aldi Leamington Spa


EVO Energy has been recognised for its innovative work on the Aldi Eco Concept Store in Leamington Spa, showcasing a strong commitment to sustainability in retail. The project aimed to create a retail environment that significantly reduces energy consumption and minimises carbon emissions, aligning with Aldi’s broader sustainability goals. The store features advanced


materials designed for environmental responsibility. Timber fibre insulation, known for its excellent thermal performance and low carbon footprint, is complemented by cement replacement concrete, which collectively reduces the construction’s overall environmental impact. Additionally, recycled lighting columns and low-temperature tarmac enhance resource efficiency and energy conservation. A major feature is the solar PV system, which consists of 709 panels generating 167,409kWh of clean electricity annually. This renewable energy production contributes to a substantial reduction of approximately 34,666kg of CO2e emissions in the first year. As a result, the store achieves a remarkable 57%


Highly commended: Keep it Cool Refrigeration for Devon bungalow installation


Multiple renewable technologies came together on this project in Stonecrest, Devon, to transform an old Woolaway bungalow into an energy-efficient home. Woolaway houses, built in the post-World War II era, are prefabricated concrete structures notorious for poor thermal insulation. The installation features a solar PV system, solar thermal heating, and both air-to-water and air-to-air heat pumps. This comprehensive approach replaces the former reliance on inefficient bottled gas heating – previously consuming four 47kg LPG bottles every three weeks – thereby significantly reducing both carbon emissions and overall energy use.


In addition to renewable


energy sources, the project prioritised improved insulation and underfloor heating, effectively addressing the thermal inefficiencies typical of Woolaway constructions. High-performance insulation materials were installed in walls, ceilings and floors, leading to reduced heat loss and more efficient heat distribution. As a result, the home now


operates with a substantially lower energy demand. Initial data shows the solar PV system generating over 5.27 MWh of electricity annually, underscoring the project’s successful shift to sustainable energy practices and serving as a model for similar initiatives.


Judge’s comment: “Excellent project transforming such an inefficient home.”


Highly Commended: Prefect Controls for The Refinery, Leeds


Prefect Controls has been recognised for its innovative energy management system implemented at The Refinery, a 407-bedroom student accommodation in Leeds. The previous system meant students could override the heater programming, often setting temperatures to maximum while resorting to opening windows to regulate room temperature. This led to significant energy waste and increased utility costs. The Prefect Irus system


addresses these issues by providing centralised control over individual room heating. By replacing standard electric heaters with no-control electric


Judge’s comment: “Retail stores use huge amounts of energy and this is a great example of one using all the tools at their disposal for bigger picture thinking.”


reduction in energy demand compared to conventional designs, improving customer experience while promoting environmental awareness. The partial green roof highlights


the new store’s commitment to sustainability. It provides natural insulation, supports biodiversity, and manages stormwater, adding an ecological dimension to the building.


To ensure optimal


performance, regular monitoring and quality control measures have been implemented, confirming that the store meets established environmental and operational targets. Detailed energy consumption reports validate the significant energy savings achieved, demonstrating the effectiveness of the integrated approaches.


Judge’s comment: “The 50% reduction in heating energy and 30% decrease in total electricity consumption are remarkable achievements. ”


panel heaters and utilising a web-based portal, the system allows for real-time adjustments based on occupancy and environmental conditions. As a result, there has been a 50% reduction in heating energy per bedroom and a 30% decrease in total electricity consumption.


Highly Commended: Next Generation Renewable Energy for Little Miracles


Next Generation Renewable Energy Ltd (NGRE) supplied and installed a solar photovoltaic system – completely free of charge – at Little Miracles in Peterborough, which is expected to reduce the charity’s electricity consumption by approximately 50%. Utilising a SolarEdge inverter and JA solar panels, the system is projected to generate around 10.74 MWh of energy annually, with 4.5 MWh being self-consumed by the facility. This significant reduction


Judge’s comment: “Doing the work free of charge adds a nice community angle.”


in energy costs is anticipated to save Little Miracles approximately £40,000 over the next 20 years. The monitoring capabilities of the SolarEdge system allow the charity to track energy production and consumption in real time.
