LIT Tipperary takes the lead in Sustainable Energy Technologies

Solar PV Trainer LIT Tipperary Smart Sustainable degree

“Ireland has an opportunity to take the lead in the development of Smart Sustainable Technologies which will benefit energy security, sustainable development and the creation of employment” according to Dr Liam Noonan the programme chair of the Computing degree in Smart Sustainable Energy in LIT Tipperary.

LIT Tipperary have recently taken delivery of a number of new sustainable energy technologies so as to provide students with hands on practical experience in monitoring, assessment and design of new solutions to maximise energy efficiency. LIT Tipperary is also a partner in monitoring energy performance generated by the monitoring systems installed in 100 houses as part of the EU SERVE Project, as well as data from Eco village in Cloughjordan which include Ireland’s largest Solar Array, District heating and passive standard buildings.

“This comprehensive degree, which includes hands-on training and access to live data from sustainable communities, will give our students the necessary skills to be successful in the workforce upon graduation,” Dr Noonan explains. “Our goals for this degree are two-fold, to encourage and develop sustainable technologies, and to provide our students with the best, leading edge learning experience possible.”

The Smart Sustainable Energy degree provides a range of advanced modules in computing and sustainable energy technologies thus producing graduates with strong employment prospects within the sustainable energy and software development domain. Graduates will acquire the necessary knowledge to cope with the changing nature of the sustainable energy domain and the computing industry throughout their careers.

“This flagship degree program is the first of its kind in Ireland,” Dr Noonan said. “This degree  builds on our continued leadership in the renewable energy and sustainable development sector. We are the first college to offer a degree in the converging area of Computing and Sustainable Energy and we are delighted to be partnered with the Eco village in Cloughjordan and their community”

With the spiraling costs of fossil fuel based energy such as oil the environmental technologies market is forecast to reach €2.3 trillion by 2020, while in the EU the sector employs 3.4 million people and turns over €227bn annually.

Eco Evolution, a renewable energy business based in Co. Wexford and Switch Source a Photovoltaic company based in Co. Antrim, have designed and supplied LIT Tipperary with a Solar PV Trainer station for use on the Smart Sustainable degree programme.

“Eco Evolution is thrilled to be partnering with LIT Tipperary on this exciting project” said Frank Gethings, managing director. “We firmly believe that degree programmes like this are the way of the future and that LIT Tipperary are leading the charge on behalf of third level institutions across Ireland”

Retro fit Air Tightness project update – lessons learned so far

I have just completed the knee wall/ crawl space area of our dormer house using the vario air tightness system. I find the Vario protape ideal for attaching the membrane to the timber beams and the masonay wall and I am sealing the overlaps using KB1 tapes.

As the project has progressed I am getting more proficient at installing the membrane. Initially I was running the roll horizontal along the rafter/crawl space area and then running a second roll above it to complete the seal. I have found that it is more practical to run the roll vertical up along the rafters and use the protape and the top and the bottom. I would recommend measuring and cutting the pro tape in a big area such as your hall way so you can ensure you use the right amount. What also helps is to attach the protape to the Vario KM  Duplex UV membrane on one side this simplifies the install.

When dealing with masonry walls I run a strip of the protape along the wall and when the Duplex UV is in position remove the other side of the tape and attach. I find the Vario DS sealant impossible to use and its very messy.

The powered respirator is a god send and so is the 60 Watt LED light wand, I would not be able to do the install with out them as you are working in awkward corners with insulation dropping all around you as you position the rockwool flexi in place.

The attic overhead is next and I am hoping/praying that it will be more straightforward ! Time will tell …

Heat your home with irish timber instead of imported oil

image

With heating oil heading beyond 90 cent a litre. Irish home owners should give serious consideration to heating their homes with solid fuel stoves with back boilers. The fuel can be sourced from Irish timber growers such as ash thinnings and is not subject to the same price fluctuations. The stanley reginald stove pictured above produces 15.8kw maximum boiler output and 4kw maximum output to the room.

In order to utilise boiler stoves effectively home owners should first reduce the heat demand for their home by incorporating insulation, heating controls and if possible address any air leakage issues which can be revealed using a pressure and infra-red assessment of the home. We are in the process of addressing air leakage through the implementation of an air tightness system which should reduce the heat demand by addressing the heat loss issues due to unnecessary air movement in our dormer home.

As the cost of oil increases the payback time for implementing these solutions is rapidly decreasing. There is over 1000 acres in our parish under forestry so switching to solid fuel seems like the right decision for our home. I believe that in the next 5 years many Irish home owners will make the same decision,

Eircom should invest in rural exchanges before they invest in fibre roll out

I welcome Eircom’s announcement that they are going to invest in fibre with a 100 million euro rollout. But I wish they would spend the money on enabling all exchanges in Ireland for broadband. We live in Upperchurch in the Tipperary Hills and it looks like we will never see the exchange at Rossoulty being enabled for broadband.

This means using slower connection speed technology such as wifi (if you live in the right area) or satellite. The 3G broadband products do not offer sufficient bandwidth. So while the towns and cities in Ireland prosper, rural communities will continue to suffer.

Retrofitting- an air tightness solution

image a pressure and infrared assessment revealed significant convection loops and heat loss due to air movement in our dormer house.

We have decided to implement an isover vario air tightness solution. Which means constructing a warm roof. The insulation under the rafters is 150mm rockwool flexi which was in place but there were gaps. It is important to keep a 50 mm gap between the rockwool flexi and the roofing felt as its non breathable. The key to air tightness is attention to detail which means that it a slow job. So far I would calculate that 2 sqm is taking me 1 hour to complete.

A big issue I have is restricting air flow from the soffit to the floor joists as its open. I am using a swiss roll insulation approach to prevent this air flow and allow the air to pass up the roof behind the rocckwool flexi.

I would recommend a powered respirator as shown in the picture above. I purchased a trend air ace which weighs nearly 1 kg and has an 8 hour lithium ion battery. It means I have filtered air passing over my face and the filters take out all the insulation dust that is floating in the area. The hard hat aspect helps when you are crawling around a dormer crawlspace. If the respirator was half the weight it would be perfect but I am happy enough with it. I am also using a 60 Watt LED light wand which lasts 4 hours on a charge and a staple gun with 10mm staples.

An airtightness system has a variety of tapes and I use double sided protape, KB1 and multitape SL1. These take getting used to and I would recommend attaching the protape to the membrane before you bring it into the attic area as it sticks to everything !!

This job will take several weeks as warm weather usually restricts me to 1 – 2 hours in the morning before things get to warm. As I stated earlier it is slow and steady work and I will get there eventually. There is no pointing doing a half assed job as it is a waste of time and money.

The new J Mascis guitar – it has arrived and its a squier!

j mascis squier guitar courtesy of Thomann

There are numerous discussions on the internet about the new J Mascis signature squier jazzmaster. The most informed discussions are taking place on offset guitar forum. Some interviews conducted earlier in the year especially http://www.alrightimwrong.com/2011/02/interview-with-j-mascis-of-dinosaur-jr.html  hinted at the squier version which J hopes will encourage people to take up the electric guitar

A squier version of Js fender jazzmaster eould be less than half the price of the signature fender jazzmaster.

As of today thomann.ie have a product entry for a new mascis jazzmaster which will retail at 394 euros. There is no mention if its a squier or not but more than likely it is at that price. There is no image yet.  Thomann have removed the entry for the guitar but have left behind the image

Fender J.Mascis Jazzmaster e-guitar, artist model, basswood body, maple neck, C-shape, rosewood fretboard, 21 jumbo frets, nut width thomann 42,5mm, scale 648mm, 2x jazzmaster single coil pickups, adjusto-matic bridge with vintage style floating tremolo, toggle switch, gold anodized aluminium pickguard, finish vintage white

The original Fender Jazzmaster signature lis quiet different in its looks and probably its quality. The squier is an attractive price point and will suit people on a low budget or those who wish to mod/modify their guitar.

Fender Jazzmaster J Mascis Signature series

The colour scheme for the squier version does distinguish it from the purple fender jazzmaster, Fans would point out that J does not stick to anyone particular jazzmaster colour as the photo below shows, it also gives you an idea why the squier was designed this way.

Wexford the cultural capital of the south east

We spent the weekend in wexford. It is great to see how the old and the new exist side by side. The opera house is fantastic and there is plenty to see and do. I can recommend the bookcentre for coffee only 1.40 for an espresso.

my broadband manifesto – lay pipes as you fix the roads

With a general election happening next week I have decided to highlight to all political parties a cheap and effective way to bring broadband to all of Ireland and we the tax payer will own the infrastructure,

The idea is deceptively simple but practical, as roads are being fixed or  dug up some extra pipes should be laid also. We can then at a later date place fibre optic cabling into these empty pipes. 
It will take a few years but the costs are minimal and we can charge the ISPs to use our fibre.
