Solar Panels, the why and wherefore.

Posted by

The Organisation for Economic Co-operation and Development, the OECD, predicts that oil prices will remain stable over the next five years and may even come down by a small amount. There is nobody I know of brave enough or foolish enough to predict the same for electricity prices.

The British government recently signed a deal to pay the producers of electricity at the proposed Hinkley Point C nuclear power station twice the current price for their electricity when it starts producing in 2023.Twice the price at source does not necessarily mean twice the unit cost on your bill, currently about 17pence per kW/h in the north and 21cents in the south,  but with the amount of investment that will also be needed to update the existing supply network over the next 7 or 8 years, it might not be too far of the mark.

All of the above may well influence a choice of heating system in the short term but looking at energy matters in the longer term it’s not hard to conclude that oil and coal will, eventually, run out while it is an increase in renewables, (wind, wave and solar), combined with some nuclear that will keep the lights on. Solar panels may not immediately spring to mind as a possible source of energy in this country, given our climate, but there is enough sunshine, believe it or not, to make it worth considering in the medium term.

There are two different types of solar panels which, despite their grouping under the same nomenclature, perform in very different ways. Until recently the more common type to be found on a south facing roof was a water based system. These water based systems are, themselves, broken into two types, flat plate collectors and evacuated tubes. Water runs through the panels, is heated by the sun’s rays and is taken to your hot water cylinder where the heat is transferred to your hot water system for domestic use. Naturally the amount of heat you gain depends on the amount of sunshine hitting the panels and although there is some solar gain on a dull day, it is not significant. The systems require very little maintenance, I have had one on my roof for 23 years with only one service.

There was grant assistance for the cost of installing a water based system in southern Ireland up until 2011 through the Greener Homes scheme, unfortunately this scheme is now closed. Across the border in Northern Ireland there is no assistance at present, the industry is waiting for an announcement, due on 1st April 2015, under the Renewable Heat Incentive, which will determine the tariff owners of a system will receive as an annual payment. The cost of a system suitable for a three bed house, being 20 evacuated tubes, is approximately £2000.

The second and more topical system is a panel made up of photovoltaic cells. These cells generate electrical power by converting sunlight into direct current electricity using semiconducting materials. Although they have been around for about 50 years increases in manufacturing scale and sophistication have only recently brought them to a point where the return on the investment makes consideration worthwhile. A series on panels can be fitted either on the ground or on a roof facing generally south, but anywhere between east and west will do. The electricity generated can be used, once it has been changed from direct current to alternating current using an “inverter”, in a home or business or it can be “exported” back to the national grid.

In Great Britain and Northern Ireland there is a “feed-in tariff” for any electricity you generate from a renewable or low carbon source. This government assistance comes in the form of a ROC ( Renewable Obligation Certificate) payment of  16.32 pence per kW/h for every unit generated, regardless of what use you put the electricity to. These payments are restricted to 4kW systems for domestic installations and 12kW for commercial premises, (or 50kW if you have a 3 phase supply). If you generate more than you use in your home or business you can sell, or export, the excess back to the grid, although you will only receive around 5.1 pence per unit in return. A good quality system designed to generate 4kW will cost around £6,500 stg. If you take into consideration the annual ROC payment, usually around £550 depending on how close to direct south your roof faces and what shading there may be from trees or buildings, and add the saving you make to your electricity bills of between £300 and £500, depending on your use, you can achieve a payback of  around 6 years. It’s worth noting that your Roc payment will run for 20 years and, if the price of electricity were to double, the saving on your bill could increase to between £600 and £1000.

Sadly there are no ROC payments in Southern Ireland. Until recently you could sell excess electricity back to the grid and at a more generous rate of 9 cents per unit, but only from domestic systems.  In a recent announcement Electric Ireland stated that they will no longer buy electricity from residential properties generating electricity from renwable source such as wind and solar. In addition VAT on systems in the north is charged at 5% while those in the south are charged at 13.5%. As Ireland faces fines of “ hundreds of millions of euro per year if we don’t ensure that 40% of our electricity demand comes from renewable sources by 2020”, it’s hard to see why the Irish government is failing to encourage more domestic investment in this technology. Despite this, many Council buildings in the south are currently being fitted with PV systems designed to provide just enough electricity to meet their own needs. Considering a payback in the south of between 10 and 15 years, perhaps it’s only Councils that can find and justify the capital outlay. “The UK currently has about 3,400 megawatts of solar power installed, Germany plans to have 66,000 megawatts by 2020, Ireland has less than 1.”

“Lies, damned lies and statistics”, in that order, to quote Oscar Wilde.  It’s easy to put figures to possible future performances to prove a point and from the outside investing in a 4kW photovoltaic system in Northern Ireland under the current government deal does seem like a bit of a “no brainer” and that’s at the current price of electricity. Whether or not to invest £6,500 with a return of around £20,000 over 20 years with the bonus of a reduction in your vulnerability to the vagaries of energy prices might not need a lot of pondering and on that basis we now have “pv” panels on our roof. We will monitor the system’s performance, compare it with the predictions and report back but in the meantime, a note of caution on the timing.

A consultation paper was launched by the Department of Enterprise, Trade and Investment into possible changes to Northern Ireland Renewable Obligations (NIRO) and we understand that the paper recommends reducing the value of the ROCs payments by about 60%. DETI has received around 300 negative responses to such a proposal and we are led to believe that from April 1st 2015 a less dramatic cut of 40% may be announced. This would extend the payback time from approximately 6 years to 8 or 9 years. Anyone who registers their system before the announcement will get the current rate for the full 20 year period.Burns - Enniskillen PVI

National Architects in Schools Initiative

Posted by

We’re delighted to say that since Christmas, we’ve been working with students at Loreto Community School in Milford as part of the National Architects in Schools Initiative.

The Initiative is run by the Irish Architecture Foundation (IAF), and the idea is to give students hands- on design experience under the guidance of local architects.

The IAF is working in partnership with the national network of Teachers’ Education Centres to train and resource both architects and teachers. Five Education Centres, in Cork, Donegal, Dublin, Galway and Wexford, are acting as regional hubs for the initiative which takes place in 25 schools.

The programme allows us to steer the students as they analyse their built surroundings and identify areas that they would like to improve, and then to help them come up with imaginative suggestions and solutions.

It’s great to be involved, because I live locally, my wife is from Milford (and teaches in the school) and because our son is a first year student there. I’ve spoken to students in the school a few times in the past about a career in architecture, so I’m familiar enough with the place.

We’re working in the school with Transition Year students and their teacher Mr. Patrick Curley, and we began by asking the students to look at the village of Milford, and in particular how their school is located in relation to the village centre. Now we’re looking at ways of strengthening the links between the school and the centre, in the process developing ideas about how to regenerate disused buildings and spaces in and around Milford. I’m sure we can pull together a lot of good design ideas, and we’ll use the best of the school’s technology and art departments to demonstrate them.

Our role will be to provide the support that will allow the students to draw conclusions from their analysis, and to go on and design the kind of buildings and places they’d like to see in Milford. We hope that they let their imaginations run loose, and push the boundaries as much as they want. We won’t be telling them that their buildings won’t stand up or that they’d cost too much, because what we really want is to develop their vision and encourage their creativity. If they come up with ideas to generate a buzzing, vibrant, colourful Milford, then we’ll all have achieved something. Milford skatepark_edited-2

EPC versus BER – how does the house we designed in Co. Fermanagh rate ?

Posted by

Because we’re a bit geeky about things like this, we thought it’d be interesting to compare the Energy Performance Certificate (EPC) for the house we designed for a site outside Enniskillen, with a sample Building Energy Rating Certificate (BER) of the kind used in the Republic of Ireland. The Energy Performance Certificate that’s used in the north to illustrate the energy performance of a building is basically the same as the Building Energy Rating Certificate used in the south, although in a slightly different format. The Energy Performance Certificate shows the energy performance on an easily readable scale from A to G, with A being the best performance and G the worst. The Building Energy Rating Certificate is slightly more detailed in that it subdivides the A- G scale into A1, A2, A3, B1, B2, B3 etc. but the information on both certificates is in the same format so it’s easy to compare them. By way of explanation, an Energy Performance Certificate or Building Energy Rating Certificate is compulsory for all homes offered for sale or rent. An Energy Performance Certificate or Building Energy Rating Certificate is also required before a new home is occupied for the first time.

Heywards EPC versus Southern BER

The reason we were curious is because the house we designed outside Enniskillen got an A rating on the Energy Performance Certificate, and we were wondering whether it would have got an A1, A2 or A3 BER had it been built in the south. It turns out that with the values listed on the Energy Performance Certificate, it would very comfortably have achieved an A1 rating in the south. Which was fine until we checked the Building Energy Rating Certificate Register and discovered that of the 458,505 houses on the Register, only six are A1 rated! We’re not sure why only six have been built, but we’re guessing that it’s because the standard of design and construction that would be required to achieve A1 is so high; happily we were able to achieve that with the help of a motivated builder and an understanding client. The exciting thing is that because of the hands- on role we had during the construction, we can now see areas where we can reach an even higher standard in the future, so it’s now a case of pushing on to the next level. The next step is to design a carbon- neutral house…. now that really would be a fantastic achievement.

Just to show that it’s not all about performance, here are a few photos of the house….._MG_9231 internal to balcony

Planning Permission – do I need it ???

Planning Permission- do I need it?

Now that the long- awaited green shoots have finally started to appear, people are taking an interest in building again. We’ve been run off our feet in the office since before Christmas, and questions about planning permission are coming up time and time again. Here are a couple of links that give a really good overview of the process in both the north and the south. Don’t forget that we’ve been making successful planning applications for years and can do all of the work for you…

So who owns football anyway?

Posted by

The other day my son asked me ‘Dad, what do you call the people who own football?’ He meant FIFA of course, and it’s interesting that that’s the way it’s seen nowadays. I put it to him that he owned it, and I owned it, and so did everybody else. At least that’s how it was when I was his age. All football fans know that this is a World Cup year, or a FIFA World Cup ™ year as FIFA would have it. FIFA are in the spotlight because of street protests in Brazil against the cost of hosting the World Cup there this summer, and because of the number of deaths among poorly- paid foreign labourers working on the construction of the 2022 stadia in Qatar.

Back when I started watching football in the mid- seventies, I was fascinated by Wembley Stadium, scene of the FA Cup final every year and incredibly glamorous in my mind. I soon discovered the then- futuristic Olympic Stadium in Munich, which totally blew me away with its’ spiders web roof hung from poles. (Later, in architecture college, I made a model of the roof from a pair of tights).At the same time, The Big Match and Match of the Day provided weekly doses of English football grounds steeped in history and atmosphere.

That’s not to say it was idyllic, with football hooliganism rampant. The first game I went to was at the old Wembley Stadium in 1983, and my outstanding memory is of the heave in the crowd ten minutes before kickoff as the latecomers piled in. I ended up a fair bit away from where I started, squeezed far apart from the people I had gone to the game with. It wasn’t good, and of course the Bradford, Heysel and Hillsborough disasters were to come.

 The Olympic Stadium in Munich.

 

The Taylor report that followed Hillsborough recommended that football stadia become all- seater, and with Sky tv money soon pumping into English football, the experience of watching a game live was dramatically changed. On the positive side it became family friendly, but on the negative side it became corporate and sanitized, often out- of town and very expensive. In November 2012 I paid €180 for a ticket to watch a Champions League game in Madrid, at another of the old stadia from my childhood.

The seat was perfect, right on the halfway line, and the game was good, but I was really puzzled by the atmosphere. For a vital game, it was flat. The Borussia Dortmund fans in their bee- coloured jerseys made most noise in the away end, partly because their team was playing so well against Real Madrid, but also (I’m convinced of it) because they were standing up. They seemed to be having a party. German stadia allow standing up, and now there is a move on to allow it in English stadia as well. I’m all for it, even though the last standing game I was at, in Arsenal’s  old art deco Highbury ground, I spent the ninety minutes standing on one leg on my tiptoes leaning all over the man in front of me, like thousands of others around me. Now Arsenal play at the Emirates Stadium, with a famously dull atmosphere. Meanwhile, on quiet nights, you can hear the ghosts of Herbert Chapman and Cliff Bastin in the back gardens of the Highbury Square apartment development….

For me, the new football stadia are architecturally interesting, but are becoming the same the world over as FIFA strive for corporate uniformity. The old grounds, tightly bounded on all sides by the redbrick communities they sprang from, are becoming a thing of the past. The twin towers of Wembley, with all their history, are long gone and the most interesting things about the new stadium are Bobby Moore’s statue and Geoff Hurst’s crossbar from the 1966 World Cup final in the museum there. The new stadium lacks the atmosphere of the old stadium on match days, and has little individuality to differentiate it from the identikit stadia springing up the world over. God be with old- style regional variation such as the moat around the pitch that sticks in my mind from Argentina 78, or even the now disused- for- football Olympic Stadium in Munich. People are different the world over and our football stadia, our secular cathedrals of communal experience, should reflect that.

 

Broken Electric Shower – Make do and Mend

Posted by

Bad luck and bad timing (a few days before Christmas) with our electric shower, gave me an opportunity lately to put my ‘make do and mend’ impulses to work. Anybody who knows me will know I am wont to spending Friday evening fixing the brakes or straightening a wheel on my bike. We are often too quick to replace rather than repair domestic appliances and something in my nature resists that, if there might be a chance to open up and fix instead.

Cold water continued to flow through the shower at a great rate after I switched it off, so it was obvious that a valve of some kind had given up. Luckily I had a cut- off valve on the supply pipe to the shower, so a quick trip to the attic stopped the flow. Still, after taking the cover of the shower and staring at it blankly for a while, I knew it was a job for an expert as any attempted repair by me would likely lead to flooding or electrocution (or both) so I decided it would be best to call The Shower Man.

Tim www.showerman007.com/ , had a good look and said that there weren’t any of the usual signs of wear and tear on it, and that there was no need to replace it yet. Good, that was about €200 saved. Tim explained that it was teenagers who kept him in work- electric showers are designed to run for 15 minutes and cool for 45 minutes, but it’s the other way around when it comes to our young ones leading to a shortened lifespan for the shower unit.

Tim showed me that the filter on the solenoid had started to break up, and it was likely that a small piece of that had jammed the valve open. After replacing the part and opening the valve on the supply pipe, the shower was ready for (hopefully) another few years of action, teenagers notwithstanding. The charge for the callout and replacement part was very reasonable considering the amount I could have spent on a new shower, and the whole operation only took around half an hour.

A few helpful hints then based on my own experience:

  •  If you are in the process of building a house or a bathroom extension, have the plumber fit a cut- off valve on the water supply pipe to the shower. To avoid pressure problems, electric showers are usually fed off the mains supply to the house, rather than from your water storage tank. Without a cut- off valve on the supply pipe, you may have to cut off the water mains supply to the house in the event of a problem with the shower unit. That would be a huge nuisance at the best of times but definitely not something you want to face a few days before Christmas.
  •  Don’t assume that an older shower unit is finished if it starts to give trouble- a specialist in shower repairs could save you a fair amount of money by replacing a part rather than the whole unit (legitimate funds for bike parts).
  • Go easy on the shower- nobody needs to be that clean!

Everyday architecture no. 3

Gate way - everydayarch 3We pass them every day: every field has an entrance, and most have gate posts. Most rural houses have gate pillars of one sort or another, and we take them for granted. But what if they are more than just a necessity? What if they say something to us about ourselves and the people who came before us?

The Austrian modernist architect Adolf Loos said that ‘ornament is crime’, while the American skyscraper pioneer Louis Sullivan believed that ‘form ever follows function’. Perhaps they are right but people have always had the impulse to decorate their possessions to make statements about themselves. Gate pillars from Japanese temples to the Piazza San Marco in Venice have more symbolic importance than practical value. Loos and his fellow modernists in the 1920s and 1930s abhorred any kind of ornamentation, and while they produced many beautiful buildings some of those were not liked by the people they were built for, because they lacked any kind of personal touch. I wonder what the great modernists would have made of these gate pillars in rural Donegal? The pillars are much larger than they need to be to hold up a slim metal gate, and the little finial on top of the capping is, in modernist terms, completely unnecessary from a functional point of view. At the same time I am sure the modernists, many of whom had a great interest in primitive forms, would have had an interesting discussion on ideas of marking place and ownership, of identity and belonging, and the rituals and rhythms of daily life. Perhaps it would be best to move on before they began to discuss pagan fertility symbols, and instead just imagine the pride a small farmer felt in his land, and his desire to articulate that pride and show something of his own character through big, heavyweight pillars marking his field on the side of the road.

 

Ran Mor Close, Letterkenny, Co. Donegal

RanMor Close

The latest phase of the Rann Mor housing development, the A3 energy- rated Rann Mor Close has now been completed and all the homes are occupied. These GDC (Ire) Ltd. homes, designed and certified by us, were sold off the plans and were comparable in price to older, much less energy- efficient houses on the Letterkenny market. The house designs are not compromised by energy saving devices, and for those who missed out, there’s already huge interest from buyers in the new Rann Mor Meadow phase which has just gone on site. These new homes will also meet A3 energy rating standards. For more details see http://gdcirl.com/Rann_mor.html

Testimonial – Daniel Doherty, Managing Director of George Doherty Construction (Irl) Ltd says “ The overall Rann Mor Development has been remarkably successful in the last few years. This is in no small way due to the high quality of the design and the professional service provided by Allan Curran Architects Ltd and I look forward to completing the next phase of the development at Rann Mor Meadow to the same high standard. ”
