Energy Efficiency Service: Phase 1 Report.

Phase 1 Executive Summary

An overview of the work completed by the Energy Efficiency Service from January 2009 – January 2011

Foreword

Sir Nigel Broomfield: Chairman of the Jersey Energy Trust

I have had the pleasure of Chairing the Jersey Energy Trust since 2009. It has been an eventful two years. From a standing start, the ECO-ACTIVE Energy Efficiency Service (EES) has delivered a new innovative local service that combines social and environmental benefits. I believe that the States of Jersey and Jersey Electricity plc have shown considerable foresight in approving this important area of work and I am grateful to Jersey Electricity who provided the seed funding that was instrumental in initiating the programme.

Using less energy is the highest priority if we are to achieve the goal of secure, affordable and sustainable energy provision. Reducing energy use means fewer emissions and this is essential if, by 2050, Jersey is to succeed in lowering its carbon emission by 80% compared to 1990 levels in line with our obligations under the Kyoto Protocol.

 Although these global objectives are important, we must not lose sight of the very real local benefits of this programme. Vulnerable members of our community are receiving property upgrades that will raise their standard of living and levels of comfort, as well saving them money by reducing their bills. Alongside this is the stimulus to the local economy where jobs in this sector have been secured or created as a result of the volume of work commissioned by the EES.

The first 2 years of the Home Energy Scheme have delivered impressive results. Over the lifetime of the interventions fitted in the scheme's first 2 years 60 million kWh of energy will be saved and 13,500 tones of carbon dioxide emissions will be avoided. There will also be a saving of £4 million in energy bills. This means that for every pound paid out by the programme there is a saving of £5.40 for the consumer.

Although hundreds of vulnerable people have already been helped by the EES, there is much still to do. Our programme continues to help those in our target group who have yet to apply as well as new entrants. It has also extended help to other socio-economically vulnerable groups.

In 2011 the programme was expanded to include those on the Food Costs Bonus Scheme and we are about to invite applications from the Vulnerable Over 70s. The types of interventions that the scheme can offer were also widened to create a more comprehensive service. Our aim is to deliver help as rapidly as possible without compromising our commitment to high standards of workmanship and customer care.

Another important area of activity has been to provide general energy efficiency advice to the wider public. The programme is now endorsed by the leading UK organisation in this area, the Energy Saving Trust. This autumn we will be publishing an online aerial heat loss map which will give people information about thermal loses from their property and advice on how they can improve the thermal efficiency of their homes or businesses.

The long term future of the Service is promising. Even more progress could be made if it were extended to the able-to-pay sector. Whilst this group needs less financial subsidy, partial grants and education programmes could encourage people to reduce the amount of energy they use..

I and my colleagues on the Energy Trust together with our colleagues in the Energy Efficiency Service will continue to look for cost effective ways of helping to reduce energy consumption and to use energy more efficiently in Jersey. We see that both as a benefit to the individuals concerned but also to the environment which we prize so highly.

Chairman of the Jersey Energy Trust July 2011

What is the Energy Efficiency Service?

The Energy Efficiency Service (EES) was officially launched by the Minister for Planning and Environment in April of 2009. It is funded by an annual budget of £1 million from the States of Jersey, as well as a generous seed donation of £500,000 from the  Jersey Electricity  Company.  The  scheme  provides  grant funded  energy  efficiency  improvement  measures  to  socio- economically vulnerable Islanders.

The work of the EES is overseen by the Jersey Energy Trust

(JET). The JET board provides a key advisory function to the

Minister for Planning and Environment on the development of

the  EES's  work  programme. Together  with  the  senior

management team of the Department of Environment, the JET

board provides leadership, independence and oversight on the

corporate governance of the EES. The Jersey Energy Trust

board  is  chaired  by  Sir  Nigel  Broomfield  and  comprises

individuals  from  the  energy  and  social  sectors  locally  and

Andrea Cook OBE, who also sits on the board of the Energy The Minister and Assistant Saving Trust in the UK.

What does the Energy Efficiency Service provide?

The EES has developed two schemes during its initial Phase – the Home  Energy  Scheme  and  the Community  Buildings Programme. They are both entirely new concepts for the Island and have been well received by the respective target audiences. This  report  concentrates  on  the  Home  Energy  Scheme.

The Home Energy Scheme

The first scheme launched by the EES was the Home Energy Scheme which  provides  a  wide  range  of  energy  efficiency improvements  to  socioeconomically  vulnerable  private households. Given  the  vulnerable  nature  of  the  scheme's recipients,  the  EES  operates  a  turnkey  service  in  order  to minimize the disturbance and disruption that are inevitable when carrying out works in a private home. Applicants are kept up to date through regular written and telephone communications as well as site visits if required.

All works are organised and paid for by EES staff through a selection of approved local contractors. Funding for the scheme began in January 2009 and after the initial development work, two full time staff were appointed by April 2009. The service was delighted to carry out its first energy efficiency works in June 2009. Works that qualify for 100% grant funding through the scheme include:

• Loft insulation

• Cavity wall insulation

• Hot water tank and pipe insulation

• Heating controls

• Draft proofing

• Low energy lamps

• Energy advice and information

In September 2010 the Heating System Improvement initiative

was  introduced  as  an  addition  to  the  basic  Home  Energy

work program is first revisiting existing applicants, as well as

being available to new entrants.

570 individuals assisted through the Community Buildings Programme

For a full breakdown of energy, cost and carbon savings as well as methodology please refer to the EES Phase 1 Statistics Report.

To date 735 private homes have received assistance through the Home Energy Scheme. Measures installed to date by the EES are expected to save over 13,500 tonnes of carbon dioxide over their lifetime. Per property these measures contribute to average savings of approximately £239 a year on each of our low income applicant's energy bills. The EES is an important delivery mechanism in terms of the Island's energy security and sustainability strategy and this is demonstrated by the expected annual saving of over 2,000MWh of energy through measures installed to date.

The Community Buildings Programme

In 2010 a second EES work programme was introduced. The Community Buildings Programme provides funding for energy efficiency  improvements  to  charities  and  not-for-profit organizations that provide a service within the local community to  our  socio-economically  vulnerable  target  group. The measures  received by  qualifying  organizations are  similar  to those  provided  in  the  Home  Energy  Scheme. To  date  21 charities and not-for-profit organisations that provide assistance to over 570  individuals are  receiving  assistance  through  the programme. These include:

Little Sisters of the Poor: Independent living apartments,

residential  and  nursing  care  for  over  90  elderly individuals with low income.

• Loft and cavity wall insulation provided. Heating review underway.

Jersey  Council  on  Alcoholism: Provides  half  way

accommodation  for  up  to  11 adults  in  recovery  from alcohol addiction issues.

• Loft insulation, draught proofing and low energy lamps provided. Boiler replacement and heating system improvement underway.

Les  Amis  Incorporated: Offers  care  and  support  to

adults  with  learning  difficulties  in  several  residential properties.

• Loft insulation provided to six properties to date. Heating reviews underway.

St Ouens Parish Accomodation: Sheltered housing for

49 elderly parish residents.

• Loft  and  cavity  wall  insulation.   Boiler replacement and heating controls improvement in

progress.

Setting the standards

The Energy Efficiency Service process does not finish when the works at a property are complete. We pride ourselves on the service  we  provide  to  our  clients  and  a  quality  assurance process is carried out on works at a sample of properties to ensure our works meet necessary standards. All contractors working for the scheme undergo a competitive tender process including checks on qualifications and security to ensure their suitability for our work. Applicants are also invited to complete our feedback process and, if they wish, allow us to access and review their energy bills. The vast majority of our applicants leave positive comments with nearly 97% of respondents rating the EES process as a whole as either good or very good!

by the service is delivered by endorsed staff, who have been

trained to deliver best practice standard energy saving advice.

All facts and figures in consumer facing EES documents are

How have we done?

At the outset of the Energy Efficiency Service a range of Key Performance  Indicators  (KPIs)  were  identified.   Of  the  four indicators that have been assessed[1], the EES is meeting or exceeding its requirements in all instances:

• KPI: Deliver 15% reduction in energy use

• Achieved:   Average  per  property  saving  of 2,989kWh per year equating to 16.9% of average domestic consumption.

• KPI: Household energy saving of £70 to £250

• Achieved: Average per property  bill reduction of £239.

• KPI: Reduce greenhouse gas emissions (CO2) by 15%

• Achieved: Average per property reduction of 639kg per year equal to 16.1% drop in applicant's carbon footprint'

• KPI: Provide improvement to end use of heating energy to at least 800 households

• HES measures implemented within 735 households as well as 570 individuals through the Community Buildings Programme

Applicant's feedback comments

"Compliments to all concerned. Very pleased with all that has been done. My bungalow is much warmer. I even turn the stat down. Once again many thanks much appreciated".

* - In contrast to the electricity and gas consumption oil is presented as kWh purchased (rather than consumed) per year (rather than per quarter) due to the fact that oil purchases are carried out in bulk' and quantities purchased during one period can be used in the following period in some instances.

What next?

Beyond these landmarks, the EES has been continually looking to  expand  its  remit  and  assist  in  energy  awareness  and reduction wherever possible. For instance, through attending public events the EES team aims to increase awareness of the assistance available to vulnerable members of the community, as well as providing energy saving advice to the general public.

Through 2011 and into 2012 this type of information provision will be expanded through an energy efficiency advice line open to the general public, an online aerial thermal image showing property heat loss as well as assistance to schools hoping to decrease their energy consumption.

In the long term even greater progress can be made if  the Service could be extended into the able-to-pay sector where partial  grants  and  education  programmes  can  help  and encourage  people  to  take  action  on  improving  their  energy efficiency. The forthcoming Energy White Paper is expected to recommend  this  route  as  the  most  cost  effective  way  of achieving the Island's long-term energy reduction targets.

Energy Efficiency Service January 2009 – 31st January 2011 Phase 1 Statistics

1. Introduction

The Energy Efficiency Service (EES) was initiated in 2009 with agreed funding of £1 million  from  the  States  of  Jersey  and  a  seed  donation  of  £500,000  from  Jersey Electricity. After an initial setup stage, the service was officially launched in April 2009.

The first programme established by the EES was the Home Energy Scheme. This provides  a  turnkey  service  to  a  socio-economically  vulnerable  target  audience, organizing and paying for energy efficiency improvements to low income householders.

In 2010 a second programme was introduced, the Community Buildings Programme, which provides funding for energy efficiency improvements to charities and not-for-profit organizations that provide a service within the local community to our socio-economically vulnerable target audience.

The Energy Efficiency Service is based within the Department of Environment at Howard Davis Farm and is composed of two full time employees who report to the Director for Environmental Policy. In addition specific technical support is provided by a local energy consultancy.

The work of the EES is overseen by the Jersey Energy Trust (JET). The JET board provides an advisory function to the Minister for Planning and Environment on the development of the EES's work programme. Together with the Senior Management Team  of  the  Department  of  Environment,  the  JET  board  provides  leadership, independence and oversight on the corporate governance of the EES. The Jersey Energy Trust board is chaired by Sir Nigel Broomfield and comprises individuals from the energy and social sectors locally and Andrea Cook OBE, who also sits on the board of the Energy Saving Trust in the UK.

The EES has recently undergone an endorsement and verification process by the UK Energy Saving Trust (EST). This ensures that all advice provided by the service is delivered by endorsed staff, who have been trained to a set standard enabling them to deliver best practice energy saving advice. All facts and figures in consumer facing EES documents are checked by the EST prior to publication. In addition, the carbon dioxide and financial savings in this report have been checked and verified by EST.

Phase 1 Statistics

3. Budget and spend

1. Budget overview

The EES was allocated an initial £1M budget for a pilot year in 2009. In addition Jersey Electricity Plc provided £0.5M in seed funding, which the EES can draw down from on achievement of defined benchmarks.

In 2010 the States of Jersey introduced Vehicle Emissions Duty to generate revenue for environmental initiatives, including the ongoing funding of the annual £1M budget for the EES.

At 31st January 2011 the EES had spent or committed £1,607,018 since its inception.

2. Overheads to grant spend

The EES budget is currently split into two main areas – grants and scheme running costs.

The scheme running costs encompass office set up, staff wages, development of the scheme and services, technical expertise, marketing and the day-to-day running of the service.   Costs associated  with  the  delivery  of  interventions  to  eligible parties  are accounted for in the grants budget. Overheads currently account for 23% of the overall budget with the following two important considerations:

1. Set up costs

The first two years of the scheme have included initial set up costs and engagement of technical consultants in the development of the programme. As the service becomes more established these costs will progressively diminish.

2. Turnkey service delivery

Over 60% of EES staff time (or costs equivalent to approx. £60,000 annually) is currently spent on delivering the unique turnkey service to the Home Energy Scheme applicants. This  includes  arranging  appointments  with  householders,  communicating  between contractors  and  householders,  problem  resolution  and  strict  quality  assurance processes. Due to the vulnerable nature of this target group, this is integral to delivering the grant work and is a vital part of the service that is provided and therefore should be considered  as  grant-spend. This  allowance  results  in  overheads  and  scheme administration costs of 15% of the total scheme expenditure.

Phase 1 Statistics

4. Improvements delivered through the Home Energy Scheme

1. Data recording

In late 2010 the EES introduced a Client Relationship Management database (CRM) to provide  an  effective  tool  for  the  administration,  management  and  reporting  of  the different work programmes.

Section 4 summarises the data currently captured by the CRM on the measures that have been installed by the EES as part of the Home Energy Scheme. Work in progress at the time of writing has not been accounted for.

Final figures are only entered onto the CRM when the work and the quality assurance processes are complete. In this section of the report the spend figures presented are those as recorded in the CRM. Some variance exists between these figures and the service spend recorded within the budget.

Note that the measures installed under the Community Buildings Programme work are not accounted for in the figures below.

2. Energy, fuel cost and carbon savings delivered

Estimations of  the  energy,  cost and  carbon  savings  associated  with the  measures installed under the Home Energy Scheme and Heating System Improvement scheme are also provided in this section.

All savings figures have been verified by the UK Energy Saving Trust subject to certain assumptions and provisos. Please refer to the Appendix for further details as well as the assumptions behind these figures. The Energy Saving Trust has not verified any data relating to numbers or costs of installations.

Note that the energy, cost and carbon dioxide savings for the Community Buildings Programme work are not accounted for in the figures below.

3. Energy, fuel cost and carbon saving matrices

The summary matrices in Section 4.3 provide an overview of the installations completed by the Energy Efficiency Service as well as the savings resulting from these works. These tables show the actual savings for the measures installed in the properties both on an annual basis, and over the lifetime of the installation. Many measures will show significantly lower savings than the "typical" figures presented in the Appendix (Section 7.3) due to variations in property and fuel types, and due to the proportional reduction that can apply when installing multiple measures in the same property.

Phase 1 Statistics

Key Facts Scheme savings

£791,896 of Home Energy Scheme and Heating System Improvement work

has been assessed by the Energy Saving Trust to identify the likely energy efficiency improvements resulting from grant funding.

• Measures installed deliver total annual savings of:

• 2,008,313 kWh of energy
• £160,449 in energy bill reductions
• 429,157kg of carbon dioxide

• This provides a payback of 4.9 years on the direct investment of the cost of the measures

Over  the  lifetime  of  the  installed  measures  they  will  deliver  total  energy

savings of:

• 60,057,762 kWh of energy
• £4,527,245 in energy bill reductions
• 13,581,716 kg of carbon dioxide

Per property savings

• Average savings per annum as a result of Home Energy Scheme and Heating System Improvement work are:

• 2,989 kWh of energy per property
• £239 in energy bill reductions per property
• 639 kg of carbon dioxide per property

• Over the lifetime of the installed measures they will deliver energy savings of:

• 89,372 kWh of energy per property
• £6,737 in energy bill reductions per property
• 20,211 kg of carbon dioxide per property

Phase 1 Statistics

5. Scheme paybacks on investment

1. Grant spend

Using the estimated energy, cost and carbon savings calculated Section 4, it is possible to analyse the overall effectiveness of the Energy Efficiency Service in terms of payback on  the funding  invested  in  the  service  as  a  whole. In  simple  terms,  this can be considered as the length of time required for the savings in energy cost to equal the cost of the energy saving installations.

The figures in this section include all costs associated with the Energy Efficiency Service as recorded in the section's accounts. This therefore discounts all work that is currently in progress under the Home Energy Scheme as this is not recorded within the CRM until the projects have been fully complete and signed off. Community Buildings projects are also not considered within the CRM. As the energy, cost and carbon dioxide savings resulting from these works are not accounted for within the previous section's analysis there are slight differences in the grant spend payback period between Sections 4 and 5.

The current estimated payback on the £1,016,470 invested in the EES grant budget is 6.3 years.

Phase 1 Statistics

2. Overhead spend

As the EES overhead costs are all those involved in developing, administering, staffing and marketing the energy efficiency programmes, no direct energy and carbon savings can be attributed to this area of spend. As these figures cover the first couple of years of the service and its initial development and set up costs it is expected that these will decrease relatively over time.

Note that an estimated 60% of EES staff time is spent directly on supporting the turnkey service delivery of the Home Energy Scheme. Due to the vulnerable nature of this initial target group this hands on' approach is necessary. The staff time needed to support the delivery of future programmes to the able-to-pay market should be considerably less and therefore the savings delivered per pound invested will increase

In addition, any indirect savings that have resulted from the increased awareness of energy efficiency in the Island through the marketing and outreach work and telephone advice that the EES has provided has not been quantified.

3. Total EES spend

Looking at the Energy Efficiency Service spend as a whole the payback on investment is 8.6 years. This compares favorably to an expected lifetime in excess of twenty years for the majority of major measures installed.

Energy Efficiency Service January 2009 – 31st January 2011 Phase 1 Statistics

6. Key Performance Indicators and Case Studies

At the outset of the Energy Efficiency Service a range of Key Performance Indicators (KPIs) were identified. Of the four indicators that have been assessed1, the EES is

meeting or exceeding its requirements in all instances:

• KPI: Deliver 15% reduction in energy use

• Average per property saving of 2989kWh per year equating to 16.9% of an average Jersey household's useful energy consumption (17,694kWh).

• KPI: Household energy saving of £70 to £250

o Achieved: Average per property bill reduction of £239.

• KPI: Reduce greenhouse gas emissions (CO2) by 15%

• Achieved: Average per property reduction of 639kg per year equal to 16.1% of an applicant's carbon footprint' (average Jersey household CO2 emissions are 3,967kg per year)

• KPI:   Provide  improvement  to  end  use  of  heating  energy  to  at  least  800 households

• HES  measures  implemented  within  735  households  as  well  as  570 individuals through the Community Buildings Programme

Beyond these landmarks the EES has been continually looking to expand its remit and assist in energy awareness and reduction wherever possible. For instance, through attending public events the EES team aim to increase awareness of the assistance available to vulnerable members of the community as well as providing energy saving advice to the general public. Through 2011 this type of information provision will be expanded through an energy efficiency advice line open to the general public, an online aerial thermal image showing property heat loss as well as assistance to schools hoping to decrease their energy consumption.

The KPIs provide a good overview of the scheme's performance as a whole, but one of the most telling indications of the scheme's impact is often through the testament of the applicants themselves (example below). The service receives many letters and calls from scheme recipients highlighting the positive effects of the measures installed. The following case studies are intended to highlight some of the per property' benefits that the scheme generates.

"Congratulations on a job well done. All the people concerned were efficient and cleaned up any mess that was made. I would highly recommend anybody to take advantage of this  service.  I  now  look  forward  to  the  reduction  in  my  service  charges."

7. Forward Look

In the next 12 months the Energy Efficiency Service is looking to continue to provide the Home Energy Scheme to socio-economically vulnerable Islanders. The eligibility criteria have been extended to additional groups of vulnerable Islanders whilst additional effort is being directed at increasing applications from current non-responders. This will remain a 100% funded, turnkey service and will include heating system reviews and boiler replacements where the criteria are met. As such this will remain a labour intensive service, with relatively high overhead costs.

The Community Buildings Programme will continue to provide its current service to charities and not-for-profit organisations

The Energy Efficiency Service will also be expanding its services into the able-to-pay market. Initially this will be through the provision of energy efficiency advice to the general public, delivered through a telephone advice line, educational tools, such as an aerial thermal imaging map of the Island and home energy audits.

The intention is also to a pilot scheme to provide vouchers or subsidies as incentives for Islanders to carry out energy efficiency improvements themselves. Such an approach should enable us to deliver greater savings per pound invested in energy efficiency.

In the long term even greater progress can be made if the Service could be extended into the able-to-pay sector where partial grants and education programmes can help and encourage people to take action on improving their energy efficiency. The forthcoming Energy White Paper is expected to recommend this route as the most cost effective way of achieving the Island's long-term energy reduction targets.

• EST electricity prices taken at 12.5p/kWh.

• EST insulation assumption based on gas heated semi-detached house with 3 bedrooms. The savings are the same as those used for CERT and assume a gas price of 3.67p/kWh. Savings also include a reduction factor for comfort taking'.

• Savings for the condensing boiler upgrade are for changing from an old G rated boiler to an A rated condensing boiler and a full set of heating controls.

• Figure  of  1671  kWh  for  home  energy  advice  taken  from  Energy  Efficiency Partnership for Homes, EP24, EST 2005 Energy conscious behaviour saves

money'.

• Savings for low energy light bulbs (CFLs) include an allowance for the Heat Replacement Effect. This makes an allowance for the fact the inefficient bulbs provide additional heat to the property which is sometimes useful. The gross saving from replacing  the bulb is reduced to allow for  the small amount of additional space heating that will be required.

2. Adaptations to the Jersey situation Energy saving from efficiency measures, kWh / yr

Average temperatures in Jersey are warmer than the UK average, and there are a number of other factors that could also impact on typical energy requirements and hence on likely savings. Comparing Jersey statistics with UK statistics, the average domestic space heating requirement is 9.8% less than the UK average. All UK savings for space heating measures have therefore been reduced by a factor of 9.8% for Jersey.

Typical properties in Jersey

Both the EST and CERT cost and carbon saving figures are based on a 3-bed semi- detached property with gas central heating.

Source: BRE Domestic Energy Fact File 2008

As 71% of domestic energy use in the UK is from gas it is reasonable to use gas figures for the average property.

Source: Jersey Annual Social Survey 2006

However, in Jersey as the space heating fuel mix is 40% electricity, 38% oil and 13% gas it would be inappropriate to use gas as the fuel type for the average property.

The majority of homes in Jersey are either oil heated detached houses or electrically heated flats. Given the current focus of this scheme on privately owned properties, an oil heated three bedroom detached house has been used to determine typical savings.

Actual savings for evaluations of the scheme have been based, wherever possible, on actual fuel and property type for the home where the measure was installed. Where this information was not available, the average Jersey fuel mix for the property type (house or flat) was used.

Energy price and carbon emissions factors

The unit prices and the carbon emissions factors for energy in Jersey are different from the UK and therefore it is not appropriate to use the UK figures, as illustrated in the tables below.

Source: EXPLANATORY MEMORANDUM TO THE ELECTRICTY AND GAS (CARBON EMISSIONS REDUCTION) ORDER 2008 No. 188

Source: Gas and electricity prices taken from Jersey Gas and JEC website published tariffs on 23.2.11. Oil price taken from Consumer Council Newsletter, Dec 2010, average price at 10.11.10. Oil prices 52.55 p per litres converted by 11.84kWh/litre.

The oil price calculation above includes an error – the gross calorific value of kerosene heating oil is 10.31 kWh/litre, not 11.84. Correcting for this, the following price and carbon dioxide factors have been used throughout this report:

Limitations

Assessment of savings has been based on recorded data where available. However, there are significant gaps in the data, particularly to do with heating fuel and size of property. For some properties it is clear what the heating fuel is (for example if a new oil boiler has been installed) but for other properties this information is not available and so savings have been based on the appropriate Jersey fuel mix.

Savings figures are also based on assumptions about what was in place prior to installation. In most cases reasonable assumptions can be made about the likely efficiency of the pre-existing system or fabric. However there is considerable uncertainty surrounding loft insulation.

Installers recorded the thickness of insulation added, but they did not record the level of insulation already in place, if any. This can impact on the savings achieved by a factor of more than 30 in some circumstances. To minimize the error in the estimated savings a mix of possible installation scenarios was assumed. However it is possible that the savings from loft insulation have been significantly over- or under-estimated.

Combinations of Measures

Some measures will, if installed, have an impact on the effect of other measures in the same property. This is one reason why the scheme has been assessed on a property by property basis, rather than by applying average measure savings across the board. However, this also has the affect of exaggerating the apparent significance of some measures in relation to other measures, depending on the order in which the savings are applied.

In this assessment, insulation and draughtproofing measures have been assessed as if applied first. The savings from boiler replacement are then assessed as if applied to an insulated property (which reduces the savings compared to a "standard" saving). Heating controls are applied last, and so their impact is reduced further.

This ensures that the total saving is not over-estimated. However it does have the effect of increasing the apparent payback for heating control measures and reducing it for insulation and draughtproofing measures. The payback figures quoted for individual measures should not be relied on heavily in making comparisons between the cost effectiveness of different options.
