Nottingham, one of the major cities in East Midlands is situated 130 miles north of London and has official population of 305,750.

The area around Sneinton Road, Sneinton , Nottingham  is considered as the most appropriate for the development of the REMOURBAN demo site The site is very close to the existing district heating. The pipe line is reaching the Bio City which is very close to Sneinton Road (100 – 200m).

There is a substantial Nottingham City Council (NCC) housing in the area that need upgrading to much more energy efficient state. Close the site is one of the famous city landmarks – George Green’s Windmill and science centre.

Low Energy districts actions

  • Monitoring - advanced monitoring system, including user behavior
  • Retrofitting - 28.318 m2 district retrofitting | 411 dwellings | 1.600 residents | 35% energy savings
  • Renewable heating & cooling - Connection with city scale district heating (90% renewable and waste heat)
  • Electricity distributed generation - Combined Heat and Power generation (CHP) | Photovoltaic panels on roof (75 kWp)
  • Advanced bems - Advanced Building Energy Management Systems (BEMS) for monitoring of district heating and building comfort controllers

An intensive retrofitting program will be developed in the Sneiton area in order to achieve a low energy district (23.318 m2 of conditioned area).

The retrofitting intervention strategy focuses on the primary measure of solid wall insulation and its use on a variety of substrates and property ages, and on ‘room in the roof’ insulation on properties that are over 100 years old. The H2020 funding for these measures will be maximized with national Energy Company Obligation (ECO) funding.

The district heating intervention will extend the existing district heating network (4.700 homes) by using the low temperature return heating, for the first time on this system and, maybe, in UK. The intervention will use a single buffer vessel at each of low raise blocks to act as a thermal storage unit regarding the distribution into the individual flats. The thermal storage unit will be connected to larger scale solar thermal installation on the roof of the blocks to add additional onsite generation from renewables.

The south facing roofs of the blocks will be fitted with photovoltaic systems to give a total array size in the region of 75kWp. Within the individual blocks, the intervention aims to supply a low temperature flow to go through class 2 or 3 meters into the individual properties and deliver low temperature heating to be supplied into the individual rooms by zone activated control valves, operated by wireless room stats with individually set heating curves per property. The heat emitters will be skirting radiators, providing a healthier internal heating environment.

Sustainable mobility actions

  • Full & hybrid electric vehicles - fleet of 50 existing electric buses | 2 electric vehicles for Turistlink Bus service | Small local consolidation centre for last mile delivery with small electric vehicles
  • Charging infrastructure - recharging exploiting city’s waste | 2 fast charging points (FC) with photovoltaic panels
  • Door-to-door multimodality transport - city-card tourist smart card
  • Clean logistics - last mile delivery network for the transportation of goods (development of a small urban consolidation centre –SUCC) | 3 electrical vehicles

Nottingham leads the way in sustainable transport. It is the first city in the UK to have a stringent environmental standard for all buses entering the City Centre. Nottingham City Council is developing a fleet of 50 electric buses over 2014 to serve existing link services and the 2 park and ride bus services. Electric buses are zero CO2, NOx and PM, 50% worse to wheel CO2 than diesel counterparts.

Cost savings are estimated at more than 10.500 euros per bus per annum (dependent upon duty cycle fuel plus service cost savings). The project will establish a Tourist link bus service using 2 electric vehicles on a proposed circular route from Wollaton Hall to Green’s Mill via Nottingham Castle and Nottingham Contemporary.

The electricity to recharge the buses can be supplied by Enviroenergy, powered by burning the city’s waste, representing further carbon savings of around 40% compared to conventional diesel buses.

The project will also develop a small local consolidation center for last mile delivery by using small electric vehicles for transportation of goods at the city center reducing the number of large vehicles used for domestic and business deliveries. The solution is scalable, cost effective, makes more effective use of existing infrastructures and is of particular benefit to cities and towns.

The project incorporates the City Car Club Nottingham, an hourly car hire scheme funded through the Local Sustainable Transport Fund (LSTF) and the Work Place parking levy. The scheme is alternative to car ownership and traditional car hire and provides greener transport options for local residents by using hybrid or electrical vehicles.

Integrated infrastructure actions

  • City information platform - integrated infrastructure city model
  • Shared infrastructure - access to district smart metering infrastructure
  • Energy chain – app for energy control at home
  • Road systems - crowd-sourcing data connection (smart meter, traffic model)

In each of the retrofitted property a centralized intelligent control system will be installed, which will optimize energy use and storage to suit predicted demand profiles. The intelligent control system will be configured to provide billing for energy supplied from the district heating scheme as well as energy consumed within each individual property. This will also allow provision of alerts and alarms for assisted living, where needed, for vulnerable tenants as well as energy consumption feedback for all tenants.

For this project it is planned to develop an integrated infrastructure city model that will combine online simulation models for each one of the three building blocks, ICT for city architecture infrastructure, ICT for energy consumption infrastructure and ICT for transport infrastructure.

Society - Non technical actions

  • Community engagement - REMOURBAN common citizen engagement strategy
  • Social media strategy - common communication and engagement strategy 
  • City Visualisation – Real-time integrated city model
  • Implementation plan - REMOURBAN common strategy for development of integrated urban plan
  • Funding models – help private owners of retrofitted properties
  • Smart energy map – create a real-time energy map in the demo area
  • EU smart cities framework - REMOURBAN common sustainable and smartness evaluation procedure

Expected impacts

  • 50% Energy savings
  • 26% CO2 emissions avoided
  • 8.100 citizens directly involved

Attracting private investment was complicated due to the difficulties encountered when trying to explain the benefits of the project.

The team pursued a strong communication campaign. They have sought to explain the benefits of the project by providing examples of best practices implemented in other similar projects.

The inefficient communication between the different departments of the Municipality resulted in delays. In addition, there was administrative confusion over sharing the responsibility, especially between the financial and urbanism departments. 

A cross-cutting smart cities department was created in the municipality, designed to aid the implementation of these projects. The department was not functioning perfectly, but it has proved helpful in dealing with the administrative burdens.

Owners (usually the Municipality) were aware of the merits of the project and they were committed to implementation. However, the tenants were used to doing smaller interventions (e.g. painting the walls) and did not immediately see the value for the community as a whole. 

The developers have tried to bridge the problems encountered with the tenants via communication campaigns, in which they sought to explain the benefits of this type of a project by providing examples of best practices implemented in other similar projects.
