i20: Retrofitting Homes with Energiesprong approach
Our city has
a large stock of terrace houses and other houses that are poorly insulated and
use heating systems that are not future-proof (will not be sustained beyond
10-20 years). An integrated approach for this housing stock is needed that
retrofits them and makes them future-proof. One such integrated approach is
provided by Energiesprong (https://www.energiesprong.uk/). Energiesprong approach was pioneered
in the Netherlands; it upgrades a home with innovative energy-saving and
energy-generating measures, including new highly insulated outside walls and
windows, a solar roof, and a state of the art heating system with
ventive pods (a sort of air heat pump). The end result is homes that
are almost net-zero carbon. This approach has been trialed with the UK in
Nottingham and with great success (see here: https://www.nottinghamcityhomes.org.uk/news/news/more-ultra-low-energy-homes-on-the-way/ ). We suggest that the city council
gets in touch with Energiesprong to elaborate on solutions for large-scale retrofitting
of homes in the city.
Decarbonizing housing is very challenging not least because of the old housing stock. Energiesprong offers an integrated complete solution to retrofitting and future-proofing old housing stock without too much disruption to inhabitants. Given the scale of needed retrofitting it’s best to seek approaches that can be applied to whole districts and again Energiesprong is offering this service. People are currently still very reluctant to decarbonize their homes individually because of the uncertainty, lack of advice, costs etc. An approach where whole districts are retrofit at reduced costs and with council’s backing will be important to get people onboard.
