NEA Northern Ireland Energy Advice Forum
Beyond the Status Quo - Innovative
ways to tackle fuel poverty
Agenda
• Background to current (and recent) work
• Insulation
• Heating Systems including off natural gas
• Heating Controls
• Photovoltaics - energy storage and management
• Time Of Use (TOU) & Variable Rate Electricity Tariffs
• Complementary devices (VPO, Heating enhancement devices, mechanical ventilation)
NEA Technical:
• Is delivering several current projects with electrical Distribution Network operators (DNOs), and Gas (GDNs)
• A Research Project with a large Housing Association
• A Health Research Project funded by a County Council and a Clinical Commissioning Group (CCG) in England, researching Excess Winter Deaths in their county.
• Several Project Evaluations
• A significant “Redress” programme
Current & Recent Work
Overall programme aims to:
• Provide energy efficiency measures to those in or most at risk of fuel poverty
• To benefit at least as many households as did not benefit from the underperforming Community Energy Saving Programme (CESP) schemes & Areas
• Provide an independently endorsed evaluation methodology and wide dissemination of findings
Overall REDRESS Programme
Three Distinct Funds 1. Warm Zones Fund – Cost effective delivery of energy efficiency and carbon reduction measures in
volume to vulnerable householders as efficiently as possible
– Targets 3000 substantive Measures
2. Warm and Healthy Homes Fund – To establish new models of working with colleagues in health and social
care, providing measures (circa £3250) to households most at risk of fuel poverty and cold-related illness
– Targets 1000 substantive Measures 1000 Smaller Measures
3. Technical Innovation Fund – To promote new solutions to fuel poverty utilising energy saving
measures not traditionally in scope of current schemes – Targets 640 substantive Measures 900 Smaller Measures (circa £7500 & £1000 respectively)
Drivers
• Understand the performance of technology in fuel poor households
• Understand the acceptability of technology in fuel poor households
• Understand the performance of technology in comparison to “expected” performance – SAP, modelled, manufacturers predictions etc
• Suggest alternative deployment models for funding mechanisms
NEA Research & Technical Projects
(TIF)
TIF: Headline Facts & Figures
• 45 TIF Programmes now live
• £2.6 million gap and match funding generated
• Testing 30 technologies, 81 products
• Monitoring and evaluation in different household types and
buildings and combinations of products (≈ 750 households)
• Covering England & Wales working with LA/HA/RSL’s & CIC’s
• Low income FP households
• The Technical Team have numerous other Business as usual projects – evaluation, research, advisory
Impact of the technologies on • Residents energy usage (bills, data logging, manual reads) • Residents comfort level (Perception and datalogging) • Satisfaction & usability (ease of use, space, noise, performance). • Reliability & maintenance • Other outcomes (dampness, health, neighbourhoods, social) • Economics / business case.
• If technology is detrimental to the household (comfort, cost
usability etc), address the issue satisfactorily or REMOVE IT

INSULATION
Example Insulation IWI – Matildas Blanket (Planet) • PIR Modular Insulation • Pre Manufactured to measure • No plastering • Quick to Install • Tenant can remain “in situ”
EWI – Park Home Insulations Long neglected communities – previously without access to funding schemes • Comparison of various systems and application methods / costs • Jubizol, Paraclad, ParexTherm render, SSP Envirowall, Aerogel, • Plastering / no plastering methods • Some complimentary technologies eg MVHR or renewables / energy
storage
Underfloor – Innovative Application of PU Insulation • Robotic application of underfloor • Robotic Surveying & mapping • No intrusive demolition for access • Minimal damp risk • Tenant can remain “in situ”
Example Insulation Air Tightness & Insulation • 2 projects looking at whole house approach – Architect led • Survey • Measures identified – • Measures Installed eg thermal breaks, party wall, windows, doors,
eaves underfloor etc.
Insulation - Monitoring
Complemented by • Questionnaires • Energy use data • Thermal Imaging • Air Tightness
Heating Systems

Heating Controls
• “We often find older generations are not able to use their heating controls effectively – it could be that the devices are too complicated to programme, or that they have arthritis or poor eyesight preventing them from operating them”
• “So there is the opportunity for the installer or electrician to help by recommending and installing effective and easy to use heating controls, and ensuring they demo them properly so customers understand how to use them.

Photovoltaics and Energy Storage &
Management
Example PV Related Projects
Power Diverters • Divert excess PV generated electrical power to immersion heating • Maximise use of PV energy without impacting on Government
Incentives (FIT / ET) • Efficient & Automatic
Battery Storage • Several systems being trialled • Examples include – Tesla, Moxia Maslow, Leclanche, SonnenBatt,
Victron, Growatt, Powervault • Considering the economics as well as the results • Maximise use of PV energy without impacting on any Government
Incentives (FIT / ET)
The TIF Funding could not fund PV, but we have several complimentary products being trialled
TOU Tariffs
Dynamo with appropriate tariff • This project focusses on an electric storage heated tower block • Uses existing “old” storage heating • Minimal disruption to householders • Resident “protected” from increased charges as part of project.
Economy 7, 10, Heatwise and TOU In the future, TOU will become commonplace, our projects are
testing the early effect this may have. Several large well resourced projects exist in GB to research the effect of this on the Distribution Network our project will look at maximising (automatically) the impact of changing electricity prices on the householder.
High Temp Heat Pump with Thermal Stores • Trialling Daikin high temp heat Pumps • Trialling phase Change Material Heat Battery - SUNAMP • Take advantage of Government Incentives (FIT) • Efficient – utilise Economy 7 cheap rate electricity
Already discussed earlier
Complimentary Devices
MVHR • This project focusses on evaluating several of these devices • Example technologies include Ventive, Spirovent, Ventaxia, Envirovent • Improves comfort (Humidity), can react to high humidity • Reduces moisture - potentially mould and health issues • Recovers 75% of [usually] lost energy
Complimentary Technologies
There are several projects trialling smaller complimentary technologies with the potential to reduce energy consumption or improve comfort Some stand alone projects, some additional to another
Heating System Enhancement • Trialling several products • Example technologies include Oxypod, Magnaclean, Tadpole, Spirovent • Trialling some additives such as Endotherm
Rad Fan • This is a radiator fan evaluation project • Manufacturer claims energy saving – lets see!
Complimentary Technologies
Voltage power Optimisation • This project focusses on evaluating VPO • Many manufacturers claim substantial savings • The project aims to quantify savings – few trails have been conducted
(One being your own Northern Exposure project)
By reducing the excess voltage at the point of incoming electrical supply we can reduce bills by up to 14%
