As we approach December thermometers across the land are going only one way, and it ain't up! This means that many homes and properties across the country will be relying on their gas condensing boilers to keep their occupants comfortable in the wintry months. Sadly, this is when they are most likely to fail.
Last year was the year of the frozen condensate pipes, and whilst things don't look so perilous this winter and installers have been careful to try and protect their customers from suffering the same fate, some installations may still do so.
A condensate pipe carries condensation from your boiler to the the outside drain. More often than not the condensation barely registers as a trickle, but it can freeze layer upon layer over-time in prolonged frozen conditions, eventually backing up into the boiler and preventing it from operating.
So if your boiler cuts out unexpectedly in very cold weather, before you call a plumber or heating engineer make sure you check the condensate pipe. The video below shows how you can perform a DIY fix. Don't worry, it's not dangerous and could save you a pretty penny as well as giving you the heat and hot water you deserve this winter.

Paying the price for 'Free Electricity'
There's no such thing as a free lunch. Anyone heard that one before? It's a terrible cliche we know, but it's so applicable to the 'free solar' companies working on domestic premises that it's use can't be avoided.
Let us be clear, we do not question the integrity of the companies offering these installations - far from it. In order to succeed in that market the installations have to be high grade quality, surveys have to be very accurate and installers very speedy.
What we do question is that the installations, and subsequent electricity, are 'free'. Just because those whose roof's are used do not fork out payment at installation, does not make it 'free'. Allow us to explain.
The overall cost of supplying and installing the type of 'free' systems being installed is approximately £4,000 - this is due to bulk buying discounts and low labour rates. This 2kW system on a South Facing roof will generate three potential revenue streams; two in cash - in terms of generation and export tariffs for the system provider and owner - and one in energy savings for the roof owner. The values of which are summarised below.
So far so good. You have rented the roof to your solar supplier, or their financial backer/partner and they have effectively allowed you to gain £3,500 worth of electricity over 25 years. This represents about 10% of your electricity bills, without any up front costs. You even get the solar energy generated after the 25 year agreement is complete - not bad eh?
As with so many deals however, the true costs are in the small print.
Opportunity Cost
Having your roof filled with somebody else's solar panels mean that you cannot fill your own roof with solar panels, and neither can anyone else. This would cost a little more to procure, say £5,600 for a decent kit, so immediately you've lost out to the tune of £20,500.
Maintenance and Home Improvements
Should you wish to undertake any maintenance to your property, perhaps the electrical system or the roof, and you have to turn off the solar system, then you must pay the supplier for his lost income and seek his permission. What if you want a loft extension? Good luck. Written permission from the solar system owner will have to be sought and the final choice will always be theirs whilst the 'rent-a-roof' agreement is in place.
Selling Your Home and Redemption Penalties
Picture this; you are about to sell your home, your potential buyer likes the thought of solar panels on his new roof but he wants to own them himself and later he wants to realise the property's best value with a loft extension. It is 20 years since the solar system was installed. You refer to the system owner's contract to see what the penalty is for leaving the agreement five years early, it can't be much can it? Wrong. It's £10,000 please, and that's one of the better contracts - they might not even grant you permission to sell. Suddenly the potential buyer wants that value straight off the asking price, and who can blame him?
So like any transaction you have to weigh the real benefits against the true costs, and in most circumstances we don't think this stacks up in the home-owner's favour.

This is how we do it
There a plenty of impressive photo's online of completed Solar PV systems, glistening in the sunlight. Some of them are genuine (like those on our site) and some of them are pilfered from various corners of the world wide web, but we're not judging (needs must and all that). We've noticed a real dearth of information about the act of installation itself, and so took the opportunity to take a series of photos of a recent job in Bristol.
The slideshow above is a montage of those photos, hopefully showing our readers the various stages of installation of a 12 panel, 2.7kW Viessman. The system required two days work for 3 men on a detached house in Kingswood, Bristol. The basic stages of installation are;
1. Measuring and affixing the brackets
2. Installing the rail system
3. Laying out, affixing and connecting the panels in a series circuit
4. Siting the inverter
5. Making all necessary connections
6. Commissioning the system
Our happy customers Mr and Mrs O'Brien can expect yearly energy returns of 2,300kW/h, and a first year financial benefit (including energy savings) of £1,177. Over the 25 year FiT period they should receive an overall financial benefit of more than £29,000 - plus any inflationary increases in the generation tariff. That's about 13% per year.
Does that seem like a good return to you? Perhaps you have a comment or question on the logistics of installation or have an idea about improvements that could be made. Don't be shy, let us know your thoughts below.

Backing the Underdog
Tesco are without doubt one of the UK's most impressive companies. Since the late 90's they have grown massively, starting with their implementation of 'extra' stores which seem to sell almost everything, then moving into local market with their 'metro' stores and more recently they are challenging the likes of Argos with their own catalogue offering.
Near Cardiff in South Wales is a village called Dinas Powys and about 3 miles away from Dinas is a large Tesco superstore in Penarth. It is the main supermarket serving the area and as far as we are aware, is always very busy - in fairness it is a very good store in a handy location for the Vale and even Cardiff Bay.
Dinas Powys has a population of around 9,000 but has a definite village 'feel' to it, mostly because it is served mostly by amenities in the surrounding towns of Penarth and Barry, with access to the city of Cardiff - but also due to the village green, or Twyn as it is locally known.
Within Dinas Powys is a local grocers' shop, Valley View Fruit Stores, owned by Tony and Janice Mapstone. The Mapstones have owned the shop for over 15 years and happily serve the local people with fresh fruit and vegetables, tinned goods and other groceries - as well as flowers, plants, pet food and accessories. Only two doors down is a small Spar convenience store which trades symbiotically with the Mapstones' grocery offerings, but at the other end of the block is a large dilapidated public house of which Tesco are now the proud owners.
There is little or nothing that a local Tesco store has to offer that is not already available at Valley View Fruit Stores or the local Spar, both of which are within 100 yards of the proposed store. It begs the question, why were Tesco given permission to open such a store on this street? And what are Tesco trying to achieve by moving into the area? It's not like they don't already have a local presence, or even that they need the business. It seems that their presence will impact negatively on two businesses, owned by local people, that have served the local area successfully for years; without even bringing a discernible benefit to the local people.
Norman Environmental are not against company expansion or growth, far from it. On the other hand we firmly believe that to help the country out of recession small businesses need to be protected from the might of supermarket giants. There will be follow up blogs as the story unfolds, but we're rooting for the 'little guy'.
What do you think of the common practice of large supermarkets moving in on the territory of traditional 'local' shops? Is it the cut and thrust of fair business competition? Or should local council and government protect their constituents from big business? Let us know what you think.

Solar Tower Technology
Enviromission are an Australian company determined to make the biggest impact possible in renewable energy. The announcement that they want to build a solar tower twice the height of the Empire State Building shows just how far their ambition reaches.
A Solar Tower acts as a huge heat chimney enabling the flow of hot air to pass through turbines to generate electricity. Beneath the tower is a large solar canopy that traps solar heat, much like a green house. Then the lighter, expanded, heated air is drawn toward the central tower where it can rise to be exhausted into the atmosphere. The placement of the proposed 800 metre high tower in the Arizona desert would provide enough electricity for 150,000 homes.
How a Solar Tower Works (according to EnviroMission's description)
-The Tower
The Tower is the thermal engine of the Solar Tower technology. In it, heat is transformed into mechanical energy. The updraft inside the tower, produced by the rising lighter, hot air, is essential for this. The greater the velocity of the Tower, the higher the column of air is and the stronger the updraft. Therefore, a high-capacity power plant should have the highest Tower possible.
-The Canopy
The canopy converts a large percentage of the insulation into heat, which in turn, heats the air trapped under the canopy roof or is stored in the ground soil thermal storage system. One of the main objectives of the canopy is to lose as little heat as possible into the ambient.
-The Turbines
The Turbines transform the energy from the heat and pressure of the air into mechanical energy and the generator converts it into electricity. They work like the well known Kaplan Turbines used in hydro-electric power plants.
Cost Efficient
The estimated cost of this 200 megawatt structure is US$750 million, the company are in the early stages of site engineering. Financial modelling predicts that the tower will pay off in just 11 years - and the engineering team are for a structure that will stand for 80 years or more.
The Southern California Public Power Authority have already put their faith in Enviromission, signing a 30-year power purchase agreement with them to secure all the power generated by the proposed tower. With a predicted efficiency rating of 60% the tower is among the most efficient renewable power sources in the world and the SCPPA have identified this as a great opportunity to secure low/zero carbon energy for the 80 year lifespan of the project.
Our View
With such a short payback and long lifespan the future seems bright for solar towers. The question in our mind is space, the comparison with a fossil fuel generator per square metre of land used would be a very interesting comparison. Obviously space is not an issue in our deserts, but we also need to consider the initial carbon footprint of construction.
Do you have any ideas on the solar tower, Enviromission or renewable energy in general? Comment below and let's get the discussion going.

SunnyBeam Bluetooth display
This week we were set the "challenge" of connecting a SunnyBeam Bluetooth desktop display unit to a customer's SMA SunnyBoy 4000tl inverter. I put the word challenge in quotation marks as in reality, the set-up could not have been easier.
The SunnyBeam is a very easy to use unit display unit, providing the owner with information regarding the connected solar system's performance over the course of a day, month and year as well as an estimate of the system's financial benefit since installation.
Quite simply it requires the installer to set the Bluetooth NetID setting on the SMA inverter to anything between 2-9 or A-G before commissioning. The factory setting of 1 will not suffice for connection of a SunnyBeam. Then the installer proceeds to commission the inverter as per normal.
Once the solar system is up and running it is time to unpack and power up the SunnyBeam. Follow the simple on screen instructions using the rotary scroller and button single input controller. Set the language, date, time etc and the SunnyBeam will search for Bluetooth signal from SMA inverters, choose the correct NetID and the little display unit will connect and operate correctly, job done.
All in all a triumph for SMA and another happy customer for Norman Environmental. Note that if required at a later the system can be added by decommissioning the solar system very briefly and adding the SunnyBeam post installation.
Our unit came complete with German only instructions, if you have the same experience (and don't understand German!) then you can download the English instructions using the link below.

Do androids dream of Electric Cars?
In May Audi reported that they are due to release their first full-electric car, the R8 E-tron. At the moment, the electric car industry is slow, with high prices and questions over the cars’ battery and charging facilities. However,Audi is well known for high performance high quality vehicles, so we wonder whether this development will be a watershed for the electric car industry as they begin to cross the line from fuel to fuel-cell. Audi are certainly tackling the issue of performance head on with the R8 model, with a 150 mile range and 0-60 of 4.8secs. We expect this performance will come at a premium.
Norman Environmental understand how important our cars are to us in modern society, they give us independence and freedom to go about our lives locally, nationally and even onto the continent. As a result rising fuel prices are an issue we are all struggling with, alongside the obvious carbon problem. Therefore we ask the question, is the now the time to start thinking about going electric or hybrid as a viable alternative to petrol and diesel? The Nissan Leaf has shown that a family sized car for 'about town' use is feasible, if a little pricey.
There are many other concerns with the electric car, the primary perceived problem being a general lack of charging stations. It is true that charging points are sparse throughout the UK and the public are anxious that if they invest in an electric car, recharging their battery will be an obstacle. Although there are hopes for charging stations to increase, as electric car-charging firm ‘Chargemaster’ insist that by the end of 2012 there will be 4,000 points across Britain. This asserts to us that there is a future for electric cars.
Demand wil be driven by price of fuel and the strengthening movement to reduce carbon so it’s a race to market, but will other manufacturers be able to catch up with the likes of Toyota, Nissan and now Audi?
We at Norman Environmental view electric cars as the future of private transport and are excited to view Audi’s electric effort as a beacon of hope for the future. We hope to invest in an electric or hybrid vehicle for our company soon, perhaps Audi will provide the answer.
We hope you feel as passionately about the environment as we do at Norman Environmental and if you are looking at ways you can reduce your carbon footprint in your home, please do not hesitate to contact us.

Railing against price increases
The Government released the news on Monday that from 2012 rail prices will increase by 8 per cent on average, much to the chagrin of commuters everywhere and shadow transport secretary Maria Eagle.
We know as a country it is important to cut our carbon emissions to protect the environment and this is something that Norman Environmental feels very strongly about. Surely in rubber stamping these increases, the Government is discouraging the public to use communal transport by making it impossible for working citizens to keep up with these rises. The first £10k season ticket is just around the corner.
Unfortunately, the cost of our lifestyles is constantly on the up, with food, petrol, clothing etc all contributing to high inflation. How is the government not taking into consideration that the wages we receive, pay for our working lifestyle? All the hard working rail-commuters out there are the ones who are being punished by this increase.
Rail prices will hit those who travel at peak times. This may encourage the elderly and the poor to travel at different times throughout the day, but what about those who are travelling to work? Do they have any other option but to pay these ridiculous prices?
Of course, there is another alternative on longer routes; to travel around Britain using low cost airlines - which can be cheaper than using the rail network. On top of that commuters will be guaranteed a seat, but what will this mean for our environment? A plane produces far greater carbon emissions than a train (up to 87% difference) but businesses and workers may not be able to think about this consequence as circumstances force them to cut costs. This is a serious issue that the government needs to tackle as for shorter commuter journeys people may start using their cars more, again not helping Britain meet our carbon targets.
The question is, can cuts be made elsewhere as train operators need continued investment to improve our lines? Perhaps some rural services need to be considered, although if cuts are made there, how will the rural communities feel? A clear and acceptable strategy needs to be drawn up with consultation from those that matter; the public.

We've got the (Solar)World in our hands
There are many many solar products available on the market today and whilst we have our favourites, we are not tied to any one particular product. We feel that by having an 'open book' policy on materials we are able to greater satisfy the specific needs, wants and idiosyncrasies of each customer and their property - providing a bespoke design for every installation.
We have recently come across the SolarWorld range of products and are very impressed by the quality, ease of installation and competitive pricing. All of which can help us keep to our mantra of providing high quality solar PV installations, at an attractive price, to maximise customer satisfaction, confidence and financial returns.
The SolarWorld rail system is particularly interesting due to it's simplicity and size. The end and mid-brackets that hold down the solar panels to the rail are based around a round washer system that is easy to install and reduces the gaps between modules, allowing designers to potentially fit more panels per square metre. This has the knock-on benefit of maximising the kW size of the installed system and the returns that can be gained, again fulfilling our own business targets.
SolarWorld also offer a grid system, rather than just the standard horizontal or vertical rails, on which their panels can be installed. The grid system is designed to withstand greater wind speeds, such as those experienced at higher altitudes, providing greater rigidity and security where required. Just just take our word for it, have a look at the short video below.
Look out for the case studies pages on our website for a write up on our first SolarWorld installation.

Landlords can make the most of the Feed-in-Tariff
Whilst Norman Environmental would argue that anyone with a roof is a candidate for Solar PV in the UK (ok, not everyone, but close enough), certain people are especially good candidates for many different reasons, some technical some circumstantial.
It was our pleasure and honour this week to present to the Cardiff Landlords' Association about the benefits of solar PV and the feed in tariff. Whilst most people who happen across this blog will be aware that a 2kW solar PV system can bring 12% yearly yields increasing over a 25 year period - not all will know that the generation tariff price falls for systems of 4kW and above, and falls again for systems above 10kW. They fall further still for systems of 50kW and above. All as depicted by the bar chart below.
This was put to the Cardiff Landlords Association so that they may understand the basis of the feed in tariff and how it pertains to solar PV in the UK. Building on this information however, we had an ace up our sleeve; landlords with multiple properties can take advantage of the sliding scales of payment by maximising their FiT returns at each of their eligible properties.
The above graph shows, in red, how multiple property installations can each take advantage of the 43.3p tariff to maximise their returns, the grey line shows how large scale installations can suffer from diminishing returns. Over the course of 25 years therefore, 25 landlords installations of 2kW each could expect to receive £250k more in FiT income than a single 50kW installation
This means that multi-property landlords can invest for their own benefit across their portfolio, or even offer their roofs to pension funds and other investors that are looking to make long term gains from a secure, government backed opportunity.
if you are a landlord looking to make the most of the feed-in-tariff then click here to see a PDF of the full presentation or here to submit your details and we'll get in touch to assist you. Also, you can visit the Cardiff Landlords Association website, sponsored by Lobster Web Design, by clicking here.

Supply good energy to Good Energy
The Feed in Tariff is a wonderful thing indeed, allowing those of us who produce electricity via our own resources to be financially rewarded will raise awareness of the scarcity of energy and increase our respect for it.
The FiT scheme is simple too; the government tax energy providers via the carbon levy and put that money into a pot. The funds are redistributed to the energy providers who can prove that their customers have MCS accredited installations that are producing accurately measured quantities of electricity. The same customers are then reimbursed by the energy providers for each unit they produce on a quarterly basis.
A number of energy providers see this as an administrative chore, and who can blame them? After all the energy they are 'purchasing' from micro-generators is so small when compared with the levels they produce via the fossil fuel hungry power stations. Good Energy are a company who sell only renewable energy, that is to say that 100% of the energy they sell is provided through, solar, hydro, anaerobic digestion, wind turbines or any other form of non-polluting renewable energy source. They are the only company in the UK who offer such a supply.
As a result of their dedication to renewable energy Good Energy are excellent administrators of the FiT scheme. Their application packs are simple, clear and concise whilst being comprehensive and transparent in walking their energy suppliers right through the FiT process.
That is why we at Norman Environmental encourage all our PV customers, or anyone seeking to become a micro-generator, to sign up to selling their energy to Good Energy - a company that encourages micro-generation as the very back-bone to it's business. Just like us really.

Why we want the judicial review to back the FiT reduction for schemes over 50kW (part 2)
Last week we commented on how the clamour of heavily funded solar PV speculators to reverse the Government review of FiT's wasn't good for the renewable culture we need to nurture in the UK. Today we are concentrating on the economic impacts of large scale, grid connected solar farms if they are rewarded with the original feed in tariff rates as the complainants would have it.
So to set the scene: The UK is still suffering from the effects of the credit crunch and subsequent economic recession. Unemployment is high (although recent figures suggest a significant reversal, much of that has been attributed to part time workers), as is inflation, the banks are not lending, interest rates have been at historically low levels since March 2009 and the construction industry has taken a nosedive at a time where housing stocks are low.
 |
| The FiT review is designed to discourage 'solar fields' |
The Coalition Government are charged with reversing these trends, and must do everything in their power to do so for the good of the country. One of the growth sectors they have identified is the renewable/green market, since we as a country have made a legal commitment to reduce carbon output in the Copenhagen Agreement. The UK has signed up to ambitious targets to reduce our carbon impact by half against 1990 levels, so it would seem that investment in the 'green' economy is the only solution. As a means of raising funds necessary to help make this staggering change in our culture, the omni-profitable utility companies have been hit with a carbon levy, or 'green tax'. It was decreed by the last Government that this fund be re-distributed (via the feed in tariff) to those who generate their own electricity; simultaneously penalising polluters and rewarding those who turn to renewable sources of energy. 2 birds, 1 stone.
In the UK there are a number of FiT qualified installations available but, much like in Germany, the overwhelming favourite, accounting for about 95% of our FiT payments, is solar PV. Solar PV installations come in many shapes and sizes but the recent FiT review has sought to discourage large scale installations on a purely financial level - and therefore make smaller systems more attractive to those who wish to invest in this vital sector of Britain's modern economy.
When thinking about the economic impact of the choice between smaller scale installations and 'solar fields', the simple economic principle to consider is economies of scale. This principle is universally accepted by economists, politicians, butchers, bakers and candlestick makers alike. The simple premise is that in the creation of any product, the more you produce the cheaper the cost per unit and the greater profit per unit you are able to make (up to a point where you maximise the marginal returns). When you apply that theory to the solar PV part of the UK feed in tariff scheme, the larger a solar PV project the cheaper the unit cost of supply and installation. However, due to the fixed value of payments the most attractive marginal return is set too high and the subsequent drain on the carbon levy pot of funds is perceived as too great by the current Government. The simple fact of the matter is that the last Government set the fixed prices too high and created a market where large value speculators can use economies of scale to make disproportionate profits. We would argue that at this juncture - where tradesmen are out of work, where students are selecting further education purely because they fear unemployment - it is the grass roots of business that need the shot in the arm, to create the wealth of tomorrow.
| The Government would prefer you pop a few panels on your house, and so would the economy! |
Consider now the ineconomy of smaller scale production where labour represents a higher proportion of the input and proportionally greater management time and greater effort per unit is required, not to mention the design nuances of small scale bespoke projects. This means added costs, but luckily, in the instance of the FiT scheme, the unit price (set by the Government) is also proportionally higher. So smaller scale MCS installations require great input from local sources; or in other words - they provide more jobs. The income generated from the scheme then goes to the people who own the small scale installation, who are far more likely to be the kind of 'normal' folk who have been affected deeply by the recession. The scheme now turns into something that does not provide benefit only to the wealthy but also provides employment and secure income to those who are deeply concerned that today's pension market may never fulfil their requirements. In economic terms the review has reduced the marginal return for all those installations above 50kW and shifted the highest marginal returns to those installations below 50kW - making smaller installations, and smaller installers, a more attractive prospect.
In summary, we believe that if the judicial review finds in favour of the conglomerate of suppliers, installers and others it will mean more money for the rich and less for the poor; but should the Government's decision be supported it will mean that government intervention has been for the greater good, bringing more jobs, income and tariff benefits to the people who need it.

Why we want the judicial review to back the FiT reduction for schemes over 50kW
Much has been written and said about the accelerated feed in tariff review and the subsequent judicial review requested by a number of individuals and organisations. Most of the comment has been from the perspective of the very same parties who are likely to miss out as a result of the reduction in feed in tariff for those solar PV projects larger than 50kW. As a mostly small scale domestic installer, Norman Environmental feel that an important side to this argument is being ignored by both the press and the web's 'thought leaders' - who appear to us to be heavily weighed down by the financial returns of 50kW+ solar PV 'fields'.
We at Norman Environmental believe that to secure a low carbon future, the whole country has to undergo a culture-shift, and slowly we believe that this is beginning to happen.

| We're backing Chris Huhne on FiT reductions over 50kW |
Evidence of this can been seen all around us. For example, cost cutting has meant in some counties refuse and recycling waste are picked up on alternate fortnights, forcing many people to recycle more waste and recycle more efficiently. Also, things we used to take for granted like petrol, diesel, electricity and gas are more expensive than ever, meaning that we are being more frugal in our energy usage.
Meanwhile the term 'carbon footprint' has permeated our language to such an extent that we are more aware than ever that each and every one of our actions has the potential to impact the environment.
 |
| Solar fields will not create the cultural change we need in the UK |
The question you may be asking is, where does micro generation fit into this? And those of you who disagree with the thread we are developing are right to think that more solar panels equals less carbon output. You may think that since that is our goal, solar fields are are a good, swift solution to our problem.
Well no. That's not how we see things at all. In fact we would argue that that attitude is (almost) as short sighted as the one that got modern western society in this mess in the first place.
It is true that the quicker we install more solar panels and large scale renewable energy sources the quicker we will reduce our reliance on fossil fuels. But where then? How do we ensure that in the long term we treat energy with respect, thereby minimising waste? How do we ensure that we are not just putting the problem off until tomorrow? We believe that, in the minds of the subsequently ignorant population, a plethora of large solar fields are no better or worse than fossil-fuel-hungry power stations. However, should micro generation become part of UK culture - and everyone, or at least as many as possible, in the UK becomes more aware of the human, environmental and financial cost of harnessing energy for their own use - then we believe that we, as a nation, will create a culture of treating energy with respect.
The fact is that our carbon output has to be squeezed from both sides, minimising consumption AND maximising economy. Encouraging small scale installations will allow solar PV to help reduce carbon output from both directions as individual homes monitor their energy generation and consumption. In our opinion too many solar fields will unbalance the equation toward haste and away from lasting change and that is why we want the judicial review to find that the Government are within their rights to make the tariff reduction on schemes above 50kW.
Our next blog will be part 2 of why we want the judicial review to support the Government giving our thoughts on the subsequent economic benefits.

Solar Thermal and the Renewable Heat Incentive (RHI)
Solar thermal panels and tubes are designed to reduce our reliance on fossil fuels to provide heat in our homes and commercial properties. They work almost in reverse to air conditioning and refrigeration units, by harvesting solar-heat and transferring it to a water cylinder. They can be of great benefit as a subsidiary heating source especially where the property in question relies on oil or LPG gas for heat. These fossil fuels are becoming prohibitively expensive and as such the free heat provided by the sun through a solar thermal system is hugely attractive, especially to those in remote areas.
The upcoming renewable heat incentive (RHI) provides potential buyers with another financial attraction on top of the savings described above. So far we have been made aware that the RHI will apply to a number of different systems, such as;
The renewable heat incentive will work in two stages, stage 1 provides the client with a subsidy toward the upfront cost of installation and stage 2 will work in a similar fashion to the feed-in-tariff (FiT) - insofar as it pays the owner a set fee per unit of heat harvested by the system, measured in kW hours. Current indications are that the stage 1 payment for solar thermal installations will be £300, whilst stage 2 payments will be 8p per unit, and that recurring payments will be index linked and paid for a period of 20 years. The Energy Saving Trust believe that although all installations completed since 15th July 2009 will be eligible for stage 2 payments, stage 1 payments will not come into effect until 2012.

Cutting energy bills
Over the last month we have been consulting and installing for a client in Bristol, Contract and Construction Consultants who are leading specialists of contract dispute resolution with many decades of experience. The company have an office in a 3-storey Victorian semi, typical of the Clifton area of the city, and are soon to open another office in London.
We estimate that the result of our installations will be an annual saving of 30% on CCC's electricity bills and 40% on their gas bills. Norman Environmental will continue to monitor the situation at CCC over the 12 months subsequent to the completion of our installations, to measure the effectiveness of our changes. With energy bills set to rise significantly in the near future, these savings will be further exaggerated - allowing CCC to benefit from a annually rising return on the investment they have made in their property. We'll be sure to report our findings in this blog, when we expect to see a reduction in the company's annual carbon output of over 4 tonnes.

Measure and reduce your carbon footprint
As anyone who paid attention in science lessons at school will tell you, energy cannot be destroyed, only changed into another form, and an inefficient energy conversion always results in waste. Carbon dioxide (CO2) is the primary waste product of man's insatiable hunger for energy as we try to convert it into heat, light and electrical current - so much so that even our individual annual CO2 outputs are measured in tonnes.
Back through Earth's history high concentrations of carbon dioxide in the atmosphere have coincided with climate change. Compared to historical data, during man's existence on this planet anyway, today's CO2 levels are high and as can be seen below, are on an upward trend.
Weather patterns in recent years have been erratic, and other geological events such as earthquakes and volcano eruptions seem to be more common place than ever. Whether man's endless emission of CO2 is responsible for these events or whether it is the natural cycle of things is perhaps debatable - what cannot be argued however is that man's CO2 output is not helping matters, at best we are exasperating the situation, at worst we are the sole purveyors of this planet's impending doom. The likelihood is that the truth, as is so often the case, lies somewhere in the middle.
My belated point is that we as a species have a duty to reduce our impact on the world, and thereby lighten our carbon footprint. With that in mind Norman Environmental are proud to announce our association with Carbon Footprint, a leading carbon management company.
We have already begun to dovetail our own services with that of Carbon Footprint, using their calculator to assess the carbon impact of each of our clients and showing the differences made once our proposed changes are implemented. We can then offer carbon offset programmes, such as tree plantations in the UK and abroad, to bring private clients, SME's and corporates to a carbon neutral position.
As Dr Wendy Buckley, co-founder of Carbon Footprint says in a video on their website;
"Stakeholders are increasingly looking for their businesses, not be seen, but to actually have green actions in place"
There is more to reducing business's environmental impact than just pleasing stakeholders as John Buckley, MD of Carbon Footprint explains;
"For every £1 our clients spend with us on Carbon Management they typically save £10 and win £100 of new business."
That sounds like a good deal to us, save money, reduce your impact on this delicate world and increase your business.
We are so taken with Carbon Footprint that we have decided to host their free domestic carbon calculator on our own website to help our website visitors, wherever they may be in the world, to measure and understand their own carbon footprint so that they may consider the big and small changes they can make to reduce it.

The Benefits of Efficient Gas Boilers
Gas boilers are huge energy-wasting culprits in homes, business premises and public sector buildings across the UK. All domestic appliances are rated according to their energy efficiency with A being the best and G the worst, you can use this handy database from British Gas to discover how efficient your own boiler is. Substantial savings in £'s and CO2 can be acheived by replacing inefficient boilers with A rated ones. This table shows the efficiency ratings of the kind of boilers we have replaced with Viessman units (which are as high as 95% efficient!), and the subsequent savings per installation.
 |
| Data taken from here |
Since December 2010 we have replaced 21 inefficient gas boilers with A rated Viessmann 100 or 200 models as required, generally the boiler installations have been 'A' rated in place of 'G' rated boilers. Some of the old boilers actually had efficiency percentages as low as 40%, meaning that for every £1 spent on heating bills 60p was pure waste. Using the money and carbon savings shown above this equates to total savings of approximately £4,500 and 22 tonnes of C02 per year. These are exactly the kind of benefits that Norman Environmental wish to impart on our clients and the environment, translating as a yearly return on investment of nearly 12%.
The majority of this work has been completed for the Health Through Warmth scheme in the Vale of Glamorgan. The scheme is designed to provide vulnerable people with improved or brand new heating systems, as well as building insulation and other efficiency measures to keep their costs as low as possible.
Now help is available for the vulnerable in all areas of the country as Secretary of State for Energy and Climate Change, Chris Huhne, has announced that the Warm Front scheme has been restarted with a fund of £110m. It had been closed down in December 2010 but the new fund should help installers across England bring around 44,000 people out of fuel poverty.
Of course you don't have to be vulnerable or in fuel poverty to suffer from excessive energy bills as they can eat a large chunk out of your home budget, or even your profit and loss sheet. Norman Environmental can help you cut the bills in your home or workplace with our cost effective solutions. Visit our website for more information or email us for a free survey.

Crowvalley Cattery
The owners of Crowvalley Cattery, Mr and Mrs Williams, know all about good business sense, their cattery has been top-level service to local cat-lovers in South Wales for over 10 years, they have a successful short-hair cat breeding business and Mrs Williams is a top-class seamstress. It was natural therefore that they would seek to invest in microgeneration to reduce their bills and gain a 25 year income, with a solar PV installation.
Norman Environmental were the obvious choice for a couple looking for the same quality, care and attention they provide their own clients' feline family members. We specified a bespoke frame to take advantage of the southerly aspect enjoyed by the cattery roof, upon which we have mounted 8 Jinko 235M panels connected to an Eversolar inverter, to provide a 1.88kW installation.
The installation is performing very well in the spring sunshine we have been enjoying so far and Mr and Mrs Williams are proudly showing it off at any opportunity:
Over a period of 25 years the cattery should benefit by upwards of £30,000 cumulative income, assuming a moderate and steady inflation rate. The starting tariff is the 43.3p per unit (brought in by DECC for all installations from 01/04/2011 to 31/3/2012) and this will adjust with inflation, as will the benefit gained by avoiding importing energy from the grid.
Crowvalley is a beautiful part of South Wales with ample opportunity for the local people to reap the benefits of renewable energy solutions. Norman Environmental will be keeping in close contact with the Cattery, as we do all our clients, to keep tabs on the performance of their installation - the results of which will be published on our website.
