Dialight achieve 100 lumen per watt in new 17,000 lumen Industrial LED High Bay light!

Monday, February 13th, 2012
LED High Bay lights manufactured by Dialight

LED High Bay

Dialight annouced on the 9th February that they have released their new 17,000 lumen (170w) LED High Bay light. This is really impressive, not only because it breaks the 100 lumen per watt ‘barrier’ but also because it’s not from some ‘cheap foreign import’ manufacturer who manage great lighting levels by running their LED chips at 120% (yes, they’re bright – for a ‘short’ while) – this is from a company who’ve been at the forefront of real LED lights for 30 years. If you want to see what proper LED lights for factories and warehouses look like have a gander at this http://www.dialight.com/News/Details/17k_lumen_led_high_bay_press_release – then come and talk to us at Interior Control Ltd – a value added reseller for Dialight. SAVE MONEY, SAVE CARBON, SAVE THE PLANET! These lights are guaranteed for 5 years, have an LM80 rating (won’t be less than 80% of their original brightness for at least 60,000 hours!) and are British made (and British certified and tested) We also do ATEX versions of many of our lights.

LED bulbs for the home – at last!

Thursday, May 19th, 2011

LED bulbJust read a really interesting article at http://www.yourledlight.com/2011/04/led-bulbs-that-try-to-please-the-eye/ Seems that someone has finally come up with an LED bulb for replacing your average incandescent light bulb in the home.

For those of you that don’t know, it’s been a bit of a holy grail for LED manufacturers because of the way LED lighting chips work – they don’t give a multidirectional ‘glow’ like a light bulb, they give a tightly directed beam. So, the problem with creating something that works like your average bulb is – how to make it light in all directions.

Well – at last, someone seems to have come up with a solution – and they look pretty funky! So, now (if they are like our commercial LED’s) - you’ll get long life, low energy usage, very low ‘fade’, and almost no heat
generation. Of course, a bulb that lasts 10 years or so isn’t so important in a house – most of our clients though have them up at 12m and it’s a real pain (not to mention expensive) to get them changed. So, you might not see quite the benefit our commercial clients do – but I’ll buy some (I wonder if they can be
dimmed like the commercial ones?) eR

On 26th August 2010 Ian Cowie published an article in the Daily Telegraph entitled “How the roof over your head could earn £1000 out of thin air”.  In it he described how, according to British Gas, half the homes in Britain could share in a “£7bn rooftop bonanza”.

Home owners would not need to put up any capital to participate in the scheme and take advantage of the generous Feed-in-Tariff (FIT) announced earlier this year by the government. An average family might be better off by about £600 a year whilst larger installations could generate up to £1000 a year.

Does my Carbon Footprint look big in this?

Monday, March 8th, 2010

Girls_back_on_beachThe Carbon Trust has published the findings of a survey of 2047 British adults interviewed in February 2010 and asked about what they put in their shopping trolley. A quarter of people say it’s not just carbs but carbon that now influences their shopping habits.

The research shows that carbon counting now stands shoulder to shoulder with calorie counting when it comes to the weekly shop.

  • 86% of consumers want their favourite brands to help combat the threat of climate change by reducing their carbon footprint.
  • Almost half (43%) are actively seeking information about the carbon impact of the products they buy and more than half (52%) would be more loyal to a brand if they could see at a glance they were taking steps to reduce their footprint.
  • It seems we’re more ready than ever to stand by our carbon principles, with almost a quarter (22%) of respondents willing to stop buying their favourite brands if they didn’t commit to bearing the Carbon Reduction Label.
  • Cars, electrical goods and food were the products we most wanted to see making the carbon commitment.

Euan Murray from the Carbon Trust said: “People are increasingly looking for simple ways to reduce their carbon footprint, without sacrificing on price, taste or convenience.  They want to protect the environment, but are often confused about how they can make a difference.

We know they don’t want to hear about big numbers and global targets – they want to see at a glance which companies and brands are doing their bit to tackle climate change. The Carbon Reduction Label is on a wide range of our favourite household brands and is a badge of assurance that consumers can look for to help them decide what makes it into their trolley”.

What will the Carbon Reduction Commitment scheme mean to you?

Carbon Reduction requires action

Carbon Reduction requires action

01 / Introduction

By now, most Building readers will be aware of the Carbon Reduction Commitment (CRC) energy efficiency scheme starting in April. The CRC is a mandatory emissions trading scheme that will affect both public and private energy users, including property owners and occupiers. Its aim is to encourage and reward improvements in energy efficiency.

The scheme is supposed to be an integral part of achieving the government’s target of an 80% cut in emissions by 2050. By 2020, it is envisaged that the CRC will cut annual carbon emissions by 1.2 million tonnes, which equates to 1% of total emissions.

The CRC is designed to be a more equitable carbon reduction instrument compared with taxation, with the potential to reward good carbon behaviour. The key principle of the scheme is that organisations with low carbon abatement costs will invest to reduce consumption rather than buy allowances.

While at present the impact of the CRC regime is more of an administrative than fiscal burden, the future position is likely to hit budgets harder. In this article we will explore the potential impact of the legislation and the scheme in practice on an example company from an investment and operational cost perspective.

02 / What it is and how it will work

The “introductory” phase of the scheme commences in April 2010 and runs until 2013. From April, companies will have to register and compile emissions data for the first year – 2010/11 – which will be called the “footprint year”. At the outset, the scheme will place reporting requirements on organisations that fall within the scheme, the first report being due in July 2011.

Organisations that consume 6,000MWh or more of electrical energy per year through half-hourly meters (equivalent to a bill of about £500,000) will be full participants in the scheme and subject to compliance and credit purchase requirements. Organisations that use less than 6,000MWh will be subject to compliance reporting standards only.

Put simply, organisations must purchase carbon credits each April to cover all the CO2 they anticipate emitting over the year ahead.

The first purchase needs to be made in April 2011 and to inform this, the organisation can use its 2010/11 consumption as a baseline and predict possible improvements over the year ahead. A greater or lesser degree of the amount they spend on these will be returned after six months, depending on the company’s energy performance compared with others.

During the introductory phase, the credits will have to be purchased at an initial cost of £12 per tonne of carbon. This is anticipated to rise to between £40 and £50 per tonne after 2013, under a capped trading regime.

The government will rank all organisations in one league table each October based on their performance in the previous year. For example, the first league table will be published in October 2011 based on performance in the “footprint year” (2010/11). On publication of the league table, the money will be redistributed among the participants in the scheme. The government will rank each participant based on three metrics:

Absolute metric: Percentage change in absolute emissions of each organisation compared with previous years

Early action metric: Good energy management during the introductory phase

Growth metric: The growth or decline of an organisation during its participation in the CRC (that is, percentage change of emissions per unit of turnover).

During the three year introductory phase, the weighting placed on each metric is shown in this table.

Table showing CRC Introductory Phase weighting

Table showing CRC Introductory Phase weighting

03 / What next?

In subsequent years a 75% weighting will be placed on the absolute metric and 25% on the growth metric. The league table will not be based on the total emissions of each organisation, but on the percentage improvement each one makes each year.

After 2010/11, those organisations that make the biggest relative reduction in emissions are generally going to find themselves higher up the table and by doing so may profit, while poor performers will see a reduced return. The overall income generated by the CRC scheme will be revenue neutral from a government perspective.

This will also establish a reputational standard for all organisations within the scheme, with public transparency of their performance in the league table.

Coupled with the financial aspect, this should provide incentive to take measures to improve energy performance and reduce emissions, which would be rewarded with a higher league table position and a greater recovery (or even profit) against the cost of acquiring the carbon credits. The CRC is therefore likely to earn a place high on the business agenda.

04 / What will the impact be?

To date, there has been a general lack of understanding regarding the full financial impact of the regime, including not only the payment recycling mechanism, but also the inherent capital cost of any improvements and the cost of the actual energy used.

We know that during the introductory phase the price per tonne of carbon is £12. This alone will add about 7–8% to annual energy bills at current prices. However, during the introductory phase, even the worst performers in the league table will get most of their expenditure back via recycling six months later, which means initially the scheme will have a small financial impact.

For example, in October 2011, the best performers will receive their full monies back plus 10%. Meanwhile, the worst performers will receive only 90% of their initial outlay. In following years, the bonus/penalty amount will increase by 10% per year so that by 2015 it will be +/-50%. The CRC scheme will therefore evolve from an administrative burden to a financial one.

However, it is not as simple as receiving an extra 10% if you are at the top of the table or a 10% reduction if you are at the bottom, with incremental amounts in between. This can be demonstrated using the example calculations from the Environment Agency in the table on the left.

Using company F as an example, 2,200 allowances are bought in April 2011 at £12/tonne to cover forecasted emissions for the year ahead. Company F believes it will generate an extra 200 tonnes of carbon compared with 2010/11 when it emitted 2,000 tonnes. The amount recycled in October 2011 is based on performance in 2010/2011 not on how much is spent by the organisation. Therefore the amount back does not bear any relation to the initial outlay (that is, almost £4,000 less, even though the company finished second in the league table).

Interestingly, company H in the example doesn’t buy any allowances to cover its 2011/12 emissions, but still receives £1,094 when the revenue raised is recycled by the government. If company H does report emissions for 2011/12, then it will have to surrender the required amount of allowances and will need to purchase these through the “safety valve” prior to July 2012. In this case the price will be linked to the carbon price in the EU emission trading scheme and so could rise higher than £12/tonne of CO2.

Buying allowances in advance requires organisations to have in place sufficient systems for managing energy consumption and predicting future emissions based on the expected acquisition, improvement and disposal of assets. If not, a poor forecast might mean either too much money tied up in the CRC scheme or the risk of buying allowances at a higher rate through the safety valve.

Table showing the impact of the CRC regime

Table showing the impact of the CRC regime

05 / Hypothetical cost model

The CRC scheme is expected to flex its muscle after the introductory phase in 2013 when the amount of allowances available is capped and auctioned to organisations. Assuming the price settles at the higher end of the £40–£50/tonne of CO2 range, it could add 30% to energy bills. Of this, 40% is potentially at risk for the worst performers in 2014 and 50% in 2015. But will it be enough to encourage investment in energy efficiency measures?

This is best demonstrated using a hypothetical example of one organisation, CRC Ltd, with three office buildings fully participating in the scheme. CRC Ltd cannot pass on the cost of the allowances it purchases and pays for all the energy the buildings consume without recouping the cost through a service charge. The three buildings all have the potential for implementing energy efficiency improvements as follows:

Office 1: Nineties, air-conditioned, 20,000m2

Office 2: 2002, air-conditioned, 30,000m2

Office 3: Nineties, naturally ventilated, 12,000m2.

Energy consumption and CO2 emissions for the footprint year for CRC Ltd are given below including the cost of buying allowances during the introductory and capped phases assuming emissions stay the same.

Table showing different office scenarios

Table showing different office scenarios

Over the next five years, CRC Ltd has a capital expenditure budget available to replace elements of the building services (boilers, lighting and pumps) on a like-for-like basis, with no improvements in energy efficiency.

In spring 2010, CRC Ltd is considering three courses of action:

Scenario one Replace boilers, lighting and pumps with more efficient, but standard versions

Scenario two Spend extra on higher efficiency versions in the footprint year to reduce energy consumption in subsequent years

Scenario three Spend extra on higher efficiency versions during 2013/14 to reduce CRC under the “capped phase” of the scheme.

The investment shown in the following tables is the “extra over” amount required to buy the more energy efficient plant. So, under scenario 1, the amount of extra over investment is zero, while in the remaining two scenarios the investment is made in two different years.

For the first example, we have assumed that CRC Ltd will finish mid-table in the CRC performance league for scenarios two and three after making the additional investment in energy efficient plant. On this basis, CRC Ltd will recover all of its CRC credit cost, but will not receive any bonus payment.

As shown on table one, undertaking no energy efficiency improvements puts CRC Ltd in a better financial position compared with the extra investment required to improve their portfolio. A key assumption here however is that CRC Ltd will incur the full penalty deduction (£57,166 (allowances bought) x 10% = £5,717) each year until the more energy efficient plant has been installed.

However, what happens if we change our assumption and say that by making relative improvements in energy efficiency, CRC Ltd could finish higher in the league table and receive a bonus payment in the years thereafter?

Table1

Table1

In the next table, under scenario two, CRC Ltd receives a 10% bonus payment in 2012 and 5% in 2013. In scenario three, CRC Ltd receives a 20% bonus payment in 2014 and 10% in 2015.

Scenario three puts CRC Ltd in a marginally better financial position compared with the other scenarios, although it does assume that bonus payments will be received once improvements have been implemented.

Table2

Table2

This suggests that the relative improvement in emissions carries more value during the capped phase when the allowance price is in the region of £50/tonne of CO2. Consequently, organisations may choose to strategically plan for this and defer any investment until their league table position is confirmed.

06 / Conclusion

So is the financial liability placed on organisations by the CRC significant enough to demonstrate a convincing business case for improving energy performance in existing buildings? Not quite. However, the business case becomes more compelling when energy savings are taken into account as shown in the table below.

Table3

Table3

Early investment in more energy efficient systems can reap significant savings in terms of reduced energy costs. The example shows the initial investment paid back in less than four years. If early action is difficult due to the current economic climate, then appropriate investment in time for the capped phase (2013) will also significantly reduce CRC liability and generate substantial energy savings.

The analysis included here is simplistic but it does demonstrate that early investment in energy efficiency is best, and any action is good. Developing a comprehensive and robust business case that includes wider cost benefits (for example, CRC administrative costs, capital allowances, maintenance costs, improved internal environment, corporate social responsibility benefits, energy performance and display energy certificates) will support this and convince senior managers to invest.

The current uncertainty is the league table and where companies may expect to find themselves. This affects the bonus or penalty imposed and will skew the business case. However, running a sensitivity analysis and identifying a range of outcomes will quantify the risk of any investment strategy.

A clear understanding of the cost of various carbon abatement measures is also required. Once baseline energy consumption has been established and a survey of the portfolio undertaken, a cost effective improvement programme can be determined. These improvements will range from “soft” operational opportunities to the replacement of building services components with improved energy efficiency as part of planned capital works. Knowing the cost of each improvement and how much carbon will be abated is key to compare against buying allowances.

The CRC is a boardroom as well as a plant room issue and the benefits of taking action need to be communicated in financial speak rather than kilowatt hours, CO2 or sustainability.

Specify the correct size cooling plant

Wednesday, September 2nd, 2009

According to the Government’s 2003 Energy White Paper, buildings are responsible for about 44% of all carbon emissions in the UK. Lord Redesdale, vice chairman of the All Party Parliamentary Climate Change Group, has stated that more than a billion tonnes of carbon emissions could be saved from existing buildings by introducing very simple measures such as improving glazing, insulation and heating control.

In addition to this, commercial buildings consume, on average, about 30% more energy than they should and many, such as hotels, are far worse than this. Poorly specified, commissioned, controlled and maintained systems are to blame.

Oversized cooling plant is a particular problem with many systems designed to cope with peak summer temperatures that occur for only very short periods. Often a further 10% capacity is then added at the design stage for luck! Plant sized way beyond optimum has a hugely detrimental effect on lifecycle running costs.

The MACH control system can help. By gaining close control over energy usage throughout the building you can specify smaller, cheaper to buy and cheaper to run heating or cooling plant. By linking heating and cooling to MACH’s centralised intelligent server you can prevent energy wastage further reducing running costs. Typical savings are 30-35%.

Top ten tips: getting ready for CRC

Tuesday, September 1st, 2009

Management Today has published its top ten tips for getting ready to comply with the Carbon Reduction Commitment legislation coming into force next year. The legislation affects any company with an energy spend of more than about £500,000 a year. It is expected that as many as 10,000 UK firms will not be ready for the CRC legislation and will therefore incur fines for non-compliance.

The top ten tips are:

  1. Identify stakeholders
  2. Delegate responsibility
  3. Appoint someone to manage CRC
  4. Gather information
  5. Understand MPAN
  6. Explore early action metrics
  7. Set aside a budget
  8. Climb the league table
  9. Get help
  10. Get on with it!

The full article including detail on the above points can be found here.

What does the Carbon Reduction Commitment (CRC) mean to you?

Monday, June 22nd, 2009

In an article in Caterer and Hotelkeeper magazine on 19th June 2009; Suzy Hodgson and Jamal Gore from Carbon Clear explain the implications of the imminent Carbon Reduction Commitment (CRC) legislation due to come into effect from April 2010. This legislation is aimed at helping the government meet its target to achieve an 80% reduction in greenhouse gas emissions, as laid out in the 2008 Climate Change Act.

The CRC targets the approximately 5,000 large organisations (including hotel chains) whose emmissions are not included in the Emissions Trading Scheme but whose total electricity useage is greater than 6,000MWh for the period 1st January 2008 to 31st December 2008, across the whole business. However, approximately 20,000 companies with half-hourly electricity meters will be required to submit an initial Information Disclosure.

Failure to register or to submit the appropriate forms and reports can attract a raft of substantital fines.
