Deep Retrofit Energy Model

Nottingham City Council has secured over £5 million through the European Regional Development Fund (2014 to 2020) to deliver a project called Deep Retrofit Energy Model (DREeM).

This project aims to improve the efficiency of homes and public buildings in Nottingham and be replicable across Europe.

The project is receiving up to £5,567,493 of funding from the England European Regional Development Fund as part of the European Structural and Investment Funds Growth Programme 2014 to 2020.

The Ministry of Housing, Communities and Local Government is the Managing Authority for European Regional Development Fund. Established by the European Union, the European Regional Development Fund helps local areas grow their economic development by investing in projects which will support innovation, businesses, create jobs and local community regenerations.

The Deep Retrofit Energy Model

DREeM is a scalable demonstration project, which tests the rollout of a financial and commercial model of retrofits to homes and public buildings to increase energy efficiency and renewable energy generation.  

This deep retrofit model will deliver a whole-building analysis and refurbishment process, which achieves much larger energy savings than standard retrofit.

The aim is for the amount of energy used by a building annually to be equivalent to the amount of renewable energy created on-site.

DREeM’s ultimate objectives are

  • to prove that deep retrofit can be achieved without the need for financial subsidy
  • show that net-zero energy can be achieved by this model

Benefit to Nottingham

We are using the £5 million ERDF funds to roll out our Energiesprong, ultra-low energy homes pilot, which will include improvements to over 150 Nottingham City Homes’ (NCH) properties. The scheme will tackle some of NCH’s older housing stock that is hard to heat, lifting residents out of fuel poverty. As well as being warmer, the environmental performance of the homes will be greatly improved reducing carbon emissions and improving air quality. 

The model has been further developed to include public buildings and this rollout includes energy efficiency improvements to a city school.

Benefit to D2N2

A key objective for the project is to share best practice by trialling replication in new locations and by working new stakeholders. A number of homes in
Derby managed by Derby Homes will also receive retrofit works.

The DREeM project will deliver innovative whole-place solutions which will make the process, through retrofitting, of producing ultra-low carbon (net-zero energy) traditional homes and public buildings affordable, and empower D2N2 SMEs to deliver these solutions into a vast untapped market.
