ENERGY RATING FOR HOUSES


(Click on the title for a link to the Sustainable Ireland page about energy rating)

New European energy ratings for new houses will come into force next January (Update, already here!). These ratings will have a similar classification to the labels that you see on electrical goods such as washing machines. This initiative will give incentive to builders to incorporate the latest insulation techniques, as energy ratings will have an effect on the price of the property. Sustainable Energy Ireland did a survey and found that houses built before 1990 could lose value because of the poor heating systems and insulation properties. The measurement will be like testing the performance of the house, much the same way you would check a car for the kilometres to the gallon. One off bungalows and period properties with hollow concrete block construction would fare badly, so said Duncan Stuart from the telly. He reckons you wouldn’t think of buying an inefficient car so why by a house that will drain your resources. Denmark introduced the energy rating in the mid 1990’s and this was also included on the rental properties. They found that after the first few months house owners who were renting or selling were improving the insulation and heating in the houses prior to putting them on the market. It will be 2009 when all houses will have a rating and it will cost about €300 each. The rating will be valid for ten years as long as there are no serious alterations to the property. Although the scale hasn’t been decided, an alphabetical rating is planned. The most energy efficient will be A and the worst will be O. Duncan Stuart thinks that even the best-built houses in Ireland would only merit a C or D. The government hopes the rating system will improve the energy efficiency of the housing stock and force the construction industry to build more sustainable houses.

AIR POWERED MOTORING


DRIVE ALL DAY FOR €1.50

French engineers have designed a low consumption and low pollution engine for urban motoring that runs on compressed air technology. The CATS (Compressed Air Technology System) "
air car" from Motor Development International is a significant step for zero-emission transport, delivering a compressed air-driven vehicle that is safe, quiet and has a top speed of 110 km/h with a range of 200 km. Costing next to nothing to run, the Zero Emission Vehicle (ZEV) range - which includes a pick-up truck and van have just come onto the market.

The Zero Emission Vehicle (ZEV) prototype has been in production since 1994. The two-stroke engine is powered by compressed air stored in tanks at about 150 times the pressure of tyres on a car. The expansion of the compressed air drives the pistons to create movement, replacing the burning of fossil fuel in a conventional engine. In an air-refilling station (currently unavailable as service stations have not been fitted yet) it is estimated to take between three and four minutes to re-fuel. At home, with a 220V plug, it takes three and a half hours.

The company estimates a full tank of air will cost around €1.50 to fill and that the extra reward is knowing that you are pumping nothing harmful into the atmosphere. The hidden environmental cost with the CATS is that electricity must still be generated and the means of that production may still employ fossil fuels that discharge pollutants. Still, the savings to the pocket and environment appear well worth investigating. Four models are available for the commercial market - the MiniCAT car at approximately €6,860 euros, or the CitiCATs, including a taxi (with room for up to 5 passengers), a Pick-Up truck and a van, all retailing for approximately €9,460 euros plus taxes.

Safety Concerns
Air powered vehicles have a long history of use in Europe but were discontinued for safety and efficiency reasons. The CATS air cars have undergone stringent safety testing for modern conditions and requirements and appear to have conquered the concerns of air compression engines.

In the case of an accident with air tank breakage, there would be no explosion or shattering because the tanks are not metallic but made of glass fibre. The tanks would crack longitudinally, and the air would escape, causing a strong buzzing sound with no dangerous factor. It is clear that if this technology has been tested and prepared to carry an inflammable and explosive gas, it can also be used to carry air.

In order to avoid the so-called 'rocket effect', this means to avoid the air escaping through one of the tank's extremities causing a pressure leak that could move the car, MDI made a small but important change in the design. Where the valve on the buses' tanks are placed on one of the extremities, MDI has placed the valve in the middle of the tank reducing the 'rocket effect' to a minimum.






MY FIRST CAR CECILIA KEAVENEY

This week Cecilia Keaveney reminisces about her first experiences in the daunting world of young car ownership. It certainly highlights the problems of first time buyers!

What was your first car?
A blue Ford Fiesta

How old were you?
23

How did you get it?
I was teaching in Coleraine and completing a masters degree in Belfast so I needed a car. Given my limited budget as an eternal student at that point (6 years at university so far), I went to a reputable garage and asked for a demo range small car. I had many concepts of what I wanted but money decided it fairly swiftly and I got a 2 year old Fiesta that had previously been on a mobility scheme and so was deemed to have been well looked after and not abused.

What was it like?
It was what would now be seen to be a very old fashioned style but as it was my first car, it "had no faults" –even though it didn’t even have a radio! The first job was to get a radio sorted!

Was it reliable?
Funnily enough I thought it was. I had nothing to compare it with. I took it to my teaching job in England and when it came to MOT time, an astute teacher friend indicated that my front wheels were "Hen toed" and that this would need to be rectified if I were to pass the MOT. As a music teacher my spare time was limited but took the car to a garage. The interest that my alignment test gave the entire staff gave me some considerable concern! They explained that it went off the scale that they used! They said that in their opinion to align the car would leave it impossible to drive. They said the car’s symptoms were consistent with a car that had been in a crash and had had the steering wheel replaced in a manner just to keep the car on the road! The guys were very informative as to what I could do and suggested I take the car to a particular garage to be sorted. As I went in search of the garage that they had suggested, I unfortunately went to the wrong location where I subsequently had another nightmare experience with a second garage who basically offered to take the car off my hands for me - leaving me with neither a car or money for another. I realized m mistake and by retracing my steps I found the right garage where they gave me the confidence just to leave them the car and they would sort it all out.

How did you feel about being a car owner?

At first elated then frustrated. At first scared to even drive it in case I damaged it. Eventually with that first car I could have quite happily pressed the button on the scrap yard machine to see it squashed into a box!

Fondest memory of the car?
Saying goodbye to it.

Did you give it a name?
I described it as many things and called it many names but never labeled
it with any affection.

What happened to it?
I left the garage to do what they could. They said they would put it through the MOT. I got a call at school to say it had failed the test. I was surprised to hear it failed on a scratched windscreen. This scratch had been caused by our cat. She used to climb onto the roof via the windscreen so that she had a vantage point to see into our kitchen. The garage resubmitted the car. When I got the certificate I went straight to a car dealers and sold the car with its full MOT and bought a Rover Metro 1.1.

What was the best car you ever owned and why?
I have bought much more expensive cars in the recent past due to the amount of driving I must do in my job. Comfort and reliability have moved me to using BMWs. In reality I suppose I see a car as a tool to get me from A to B rather than a luxury. As long as they serve that purpose they are all my best cars.

What was the worst car you ever owned and why?
My first one. The man who sold it told me that as I was a young person buying my first car, he would ensure that I got a car that would be so good that I would always use his garage again. However the sales pitch didn’t match the car’s performance and subsequently I would never encourage anyone else to that garage.

What are you driving now?
An 03 BMW 320 diesel - blue again!

What is your dream car?
One that will react in a Star Trek fashion to my words "Beam me home Scottie".

SHINY CD'S


We have planted vegetable seeds all over the garden and unfortunately we have lost the piece of paper with the layout of where they have gone. It is surprising just how quickly you forget where the rows have been planted. We scattered most of the seeds in straight lines though so we should be able to distinguish them from weeds. We put loads of compost from the compost bin into the peas and bean beds. The mixture was full of small brandling worms that have been a massive hit with the blackbird that comes into the garden. The bird has taken to using its claws to dig into the soil and fit as many of the worms into its mouth. At one time it flew away with about ten of them, presumably to feed a big family. There are harmless deterrents that can be used in the garden such as wind chimes. The one that I settled for, to safeguard both the seeds and worms, were CD’s. I have collected up the CD’s that newspapers give away free and pushed them lightly into the soil around the edges of the beds. They seem to act as a vanity mirror for most of the birds that come into the garden though. I think if they are to be effective they need to be dangling on string to catch the light, otherwise they appear to be an attraction. It’s our own fault though as we have been feeding our feathered friends all winter. All being well there should be enough worms and seeds for all of us. I wouldn’t dream of trying to scare them off by any other means that might harm them in any way. Just think of the added trauma of my lad waking up one morning and finding injured birds flapping around on his vegetable patch!

CHARD SOCIETY


I have been clearing some old vegetables from the garden that have gone to seed. The broccoli we planted last year did us proud and we got meal after meal of lovely fresh shoots over the winter and spring. Another large plant in the garden that needed pulling up was a chard. Chard is a useful vegetable in the garden as it doubles up as a celery substitute from the white stalks and the green leaves are very similar to spinach. Unfortunately the chard was in my lad’s veggie patch and I made the mistake of not consulting him that it was time to pull it up. One day last week I took it upon myself to unceremoniously pull the four-foot plant up and put it to rest on the compost heap. As you can imagine, when my lad found out that his prize specimen had disappeared things got a bit heated. The outcome of my rash move is that he formed a group called L.O.C.A., which is an abbreviation for Love Our Chard Association. At present there are only three members and we are all wearing badges with a fine picture of the chard on it. If nothing else it has taught me a lesson about messing with other people things and the badges serve to rub my nose in the fact. I should have learned my lesson about the feelings of children years ago though. I remember a time when our pet goldfish died. I though it would be a hygienic idea to put it in the fire instead of burying it in the garden with a little ceremony. I can still picture the kid’s faces as their beloved pet crackled and popped in the flames. I don’t think that I will be polishing the Parent of the Year cup anytime soon!

MONTBRETIA


Montbretia are a popular plant around Inishowen. My mother has tried time and time again to grow them in the Midlands of England but they do not seem to like the hot, dry weather. The variety growing wild in the hedgerows are stately and bright enough but if you want something a little different there are plenty of other varieties to choose from. Try “Crocosmia Lucifer”, with their bright, deep red flowers. Some other ones to try if you can get your hands on them are “Crocosmia x crocosmiiflora Jackanapes”, with their red and yellow flowers, “Emily Makenzie”, which have fabulous orange blooms or the “Norwich canary”, showing off their bright yellow blooms. Whichever variety you choose, Montbretia should prove to be a glorious addition to your garden. They spread well too.
