Winner of a national innovation award, the first pilot project for Nottingham City Homes (the ALMO managing and maintaining Nottingham’s council housing) completed in early 2018 radically transformed ten social rent homes (seven terraced, three-storey houses and three bungalows) in Sneinton, Nottingham delivering super insulated, low maintenance almost net zero energy homes. This project was the first in the UK to pioneer the Dutch ‘Energiesprong’ (energy leap) initiative, which has radically upgraded the energy efficiency of thousands of homes in the Netherlands. New wall panels were prefabricated off-site and arrived in ‘full storey heights’ complete with ample insulation and a durable board finish ready to crane into place. The radical retrofit was completed in less than one week with occupants able to remain in residence throughout the works. Tenants report warmer homes and cheaper bills and the exteriors look fantastic and have really enhanced the neighbourhood. As reported in The Guardian, Nottingham is now gearing up for the UK’s biggest rollout of ultra-low energy homes to date. A new pilot currently under construction will radically improve 17 homes (10 bungalows and 7 two-bedroom, three- storey houses) adjacent to the first multi award-winning pilot, optimizing the Energiesprong solution at the start of its rollout to 155 homes in Nottingham. Solution provider Melius Homes will add improvements and carry forward the lessons learned from the pilots.
