The REMOURBAN ‘Municipal action in carbon reduction’ conference has been taking place this week, celebrating all that’s been going on over our five year involvement with the project. Find out how we’ve been involved, and how NEP have helped to make Nottingham a Lighthouse City.

A Summary of NEP’s involvement with the REMOURBAN project

Having written Nottingham City Council’s Energy Strategy (2010-2020) and managed the first large scale solid wall insulation programme in the City, we were delighted to be asked to be one of five lead partners on the Smart Cities EU REMOURBAN project. NEP has been responsible for retrofitting 49 private sector houses in Sneinton with solid wall insulation and energy efficient LED lighting, alongside being responsible for evaluating the performance of different types of retrofit tested and trialed within the project.

NEP, with help from NTU, work out the baseline of energy performance for eight property archetypes. This includes the 1900’s and 1930’s private sector houses that NEP retrofitted, as well as NTU’s portfolios of 1930’s Newark Crescent ‘Wimpey No Fines’ flats, Energiesprong 2050 homes and the Low Temperature District Heating at The Courts. The 25 1930’s properties had full external solid wall insulation, whereas the 24 1900’s Victorian homes were retrofitted with a mix of solid wall insulation measures, plus a room-in-the-roof for some houses.

NTU and NEP working together simulated each of the archetypes using Design Builder, and verified the results with the monitoring data collected by NTU team. NTU collected 2 years of data, including gas and electricity consumption plus indoor temperature and humidity in 17 homes covering 1900’s, 1930’s and Newark Crescent flats.

The NTU team’s valuable contribution to NEP’s tasks in REMORURBAN has ranged from support in simulation of energy consumption in archetypes using Design Builder, installing and maintaining sensors/monitoring equipment in NEP’s portfolios of 1900’s and1930’s properties and also advising NEP partners on how to implement the defined evaluation methodology for REMOURBAN partners across three demo sites.

NTU’s contribution was fundamental to capturing and analysing the in-situ monitoring data, playing a critical role in simulation validation to prove actual energy savings across the different retrofit interventions and property types.

NTU team’s work has enabled us to report on the difference between simulated before and after retrofit results alongside the monitored real-time results to capture a complex picture of energy/cost savings across the different retrofit models.
