Winners of the Energiesprong UK Design Competition announced

The Design Competition, successfully launched at the Accelerator Day last November by Energiesprong UK, has announced the winners! 6 consortia have been selected to participate in the programme. The aim of the Design Competition is to develop new approaches for high-performance, scalable and cost-effective net zero retrofit solutions focused on apartment blocks. The concept designs of the winning teams will be presented at Futurebuild in London, which takes place from 3 to 5 March 2020. 

The winning consortia were chosen by an international jury of experts. The consortia all consist of pioneering companies from a range of sectors and from across the UK.

The Accelerator Day in November brought together experienced, innovative and creative suppliers in the retrofit and construction industry. At this successful event, companies were able to pitch to each other to form collaborations and team up. The Accelerator Day was supported and part-funded by the Institute of Engineering and Technology, the European Interreg NWE funding programme and the London Mayor’s RAP (Retrofit Accelerator Programme).

The solutions to be developed by the teams as part of the competition must be scalable, able to be standardised, offer cost-cutting potential with increasing quantities, tenant and leaseholder-friendly, and must guarantee a long-term net zero standard. Net zero means the home generates sufficient zero carbon energy for the tenant to heat and power their home.

The Design Competition is supported by four Housing Providers, who have submitted example properties for the teams to use as their challenges. The Housing Providers involved include the London boroughs of Croydon, Kensington and Chelsea, Exeter CityCouncil and Nottingham City Homes/Council.

The DesignCompetition has 3 categories, each with 2 winners:

1.           Build Up – adding a layer on top of existing flats, while ensuring whole

The winning consortia are mentored by Energiesprong’s experts and are working together to develop their solutions. They will be presenting their concept designs at Futurebuild in London between the 3 and 5 March 2020. Energiesprong and her partner National EnergyFoundation (NEF) would love you to join here!
