Little Gransden Energy Group (LGEG) - Nov 2012

Electricity supplies:  The Sustainable Parish Energy Partnership (SPEP) that was set up by South Cambridgeshire Council, are looking at the possibility of setting up a scheme for “collective switching” of electricity supplies.  A meeting was held to discuss the proposal at Coton Village Hall on 14^th November.  Any further developments on this scheme will be reported next month.

Energy saving lights:  Further to the article last month, it has been found that Homebase were selling LED bulbs at about £4 each under their brand name, whereas most other similar bulbs from recognised manufacturers are around £6 to £10.  Also a wide variety of LED and CFL bulbs can be bought by mail order at discounted prices from BLT Direct.  Their service has been used, and found to be excellent.  Their website is: www.bltdirect.com.  Telephone number: 01473 559 501.

Electricity monitors:  These are still available on a free loan, if you should like to find out when, why, who, and what, are using so much electricity in your house!  Please contact Trevor Brown (details below).  These monitors were supplied to Little Gransden by SPEP.

There was a great show put on at the EcoHub in Gamlingay on 20^th October.  Several green energy companies had stands there, as did wild life groups such as the RSPB and Wildlife Trust.  Talks were given by Siobhan Mellon of SPEP on the Green Deal, and by Dan Jones, who designed the EcoHub.  They plan to put on another show at the EcoHub next year.

Solar pv panels:  The “Which?” magazine carried out an evaluation on the cost effectiveness of installing solar pv panels, now that the Feed in Tariff (FiT) has been reduced so much.  They concluded that it is still financially beneficial, provided that the income from the FiT is paid back in to a Cash ISA to improve the financial return.

Electricity supplies:  “Which?” magazine also reminded us that the cost of electricity has doubled between 2004 and 2012, and we have just heard of further increases of around 6% later this year.  The only ways to contain the cost of electricity is to avoid wasting power, and installing more efficient lights and appliances.

Energy saving lights:  The European governments are forcing us to change from the inefficient tungsten bulbs (which give out more heat than light), by severely restricting the sale of tungsten bulbs.  Halogen lights are only 20% more efficient than tungsten bulbs.  Compact fluorescent lamps (CFL) are more efficient, but disliked by many people, because of the flickering and dim start up.  The light bulbs of the future are undoubtedly LEDs, but these are quite expensive to buy.  However, LEDs use about 12% of the electricity compared to CFLs, last about 5 times longer, and instantly achieve full brightness.  Compared to tungsten bulbs, LEDs use about 2-3% of electricity, should last around 25 years.  Unfortunately, at present LEDs are only bright enough to replace tungsten bulbs up to 60 watts.

Lumens is the new measure of light output, and is applied to tungsten, CFL, and LED bulbs.  Wattage is the amount of electricity used by a bulb.

A 40 watt tungsten bulb may emit 300 to 500 lumens, equivalent to 7 to 11 watts for a CFL.

A 60 watt tungsten bulb may emit 500 to 800 lumens, equivalent to 8 to 15 watts for a CFL.

A 100 watt tungsten bulb may emit 900 to 1300 lumens, equivalent to 15 to 20 watts for a CFL.

Not all bulbs are equal:  “Which?” magazine found that some CFLs started quicker, and brighter, than others – GE 8 watt energy saving spiral bulbs were the quickest to start (470 lumens, equivalent to 40 watt tungsten).  Megaman Modo 8 watt stick bulb was nearly as quick as the GE bulb (420 lumens, equivalent to 40 watt tungsten).  Ikea’s Sparsam 15 watt was also rated highly for speed of illumination (820 lumens, equivalent to 100 watt tungsten).

“Best buy” LEDs include Philips MyVision 5W (250 lumens), Osram Parathorn Pro Classic A60 (650 lumens), Sylvania Toledo GLS A60 (250 lumens). 

I have successfully replaced a B&Q 11 watt CFL with a Philips Econic 7W warm white LED (350 lumens), which gave similar light output and immediate start up.

Tungsten bulbs give a warm white colour light, which is equivalent to 2700K colour temperature of light.  For comparison, candle light is 1850K, halogen bulbs produce light at 3500K, noon daylight is 5000K, blue sky, daylight lamps, and SAD light, is at 6500K to 7000K.

" The South Cambs Community Bus Service".

In April 2013, the local council will be withdrawing all local bus subsidies, we are therefore looking into the possibility of setting up " The South Cambs Community Bus Service".

We are carrying out a survey, and would appreciate your help in gathering data for your area.

DIAMOND JUBILEE CELEBRATIONS

It might have been a question of rain rather than reign but the celebrations on 4 June went well despite heavy showers, with more than 180 people attending. Many thanks to all who came, helped on the day and gave donations or raffle prizes. After welcoming everyone, especially visiting family and friends, Parish Council chairman John Gillett proposed the loyal toast and then presented Councillor Betty Bates with a photograph of Little Gransden church, resplendent with newly restored tower and weathercock, in recognition of her many years of service not only to the parish council but also to the church, the village hall and the community as a whole. Matthew Carter and family kindly supervised the substantial barbecue, with delicious puddings provided by Cynthia Murden and Barbara Horner, while Rodney Mitchell ensured musical entertainment of hits over the past 60 years. The rain held off while Bob Murden organized some races and tug of war, and presented commemorative medals to the winners. Freda Adlington presented commemorative mugs to the children. After tea, made by Phyllis Jaquest and Betty Bates, it rained again so many settled down to watch a DVD of the Queen’s 60-year reign. Kevin Diss took a splendid group photograph.

Entry for Roundabout Magazine – May 2012 edition.

If you are thinking about trying to improve the insulation, or energy efficiency, or

the heating system, of your home, then there are several opportunities to learn

from other people’s experience in May. Cambridge Carbon Footprint are holding

an “Eco Renovation Question Time” at 7.30pm on 2nd May 2012 at St Paul’s Centre,

Hills Road, Cambridge, CB2 1JP. A panel of experts will be available to answer

questions. Entrance is free, although donations will be welcomed.

There are Open Eco Homes Weekends taking place on 12/13th May, and 26/27th
May 2012. This is an opportunity to visit houses that have been upgraded to improve
their energy efficiency, and lower their running costs. See www.openecohomes.org
for more information, and booking details for these homes. Prior booking is
essential! Phone no. 01223 301842.

A Green Deal Information Centre will be held between 10am and 5pm on 26th/
27th May at the Gamlingay Eco Hub, and there are free guided tours at 10.30am, 12
noon, 2pm and 3.30pm. This building is heated by ground source heat pump, the
water is heated by solar thermal panels to heat the water, and it also has a large
solar pv panel system for generating electricity. The building is also highly insulated.
Other Green Deal Information Centres are open on 12th May at Rampton Drift,
Longstanton, and on 13th May at Coton Village Hall.

The sun did certainly shine during the last week of March! The solar pv system at
15 Main Road generated 70 kWh of electricity during that week – this was more than
the electricity generated during any week last summer or autumn. This system has
now generated 1652 kWh of electricity since installation on 27th May 2011 and the
end of March 2012.

Jubilee party and tickets

Sitting here at the computer typing this little piece with the sun shining in through the window it’s easy to imagine a sunny, summer’s afternoon spent with friends and neighbours in the enclosure behind the Village Hall.  From my deckchair I can feel a gentle breeze blowing as I relax with a cool drink after eating lunch from the delicious barbeque cooked by Matthew and helpers.  The children are all busy burning off excess energy and having a great time.

So, if the biggest queue you want to wait in this bank holiday is the queue for one of our fabulous ‘Jubilee’ milkshakes from our Milkshake Bar then make sure you save the date – Monday 4^th June from 12pm.

This is a free event for all residents of Little Gransden so all you need to bring is your tickets (more on how to get these in a moment) your picnic blankets, deckchairs and a bottle or two (if required).  Join friends and neighbours at Little Gransden Village Hall from midday on Monday 4^th June to celebrate Queen Elizabeth II Diamond Jubilee.

The enclosure to the rear of the hall will be transformed into a sports field for the occasion.  There will be running races for all ages and abilities, a three-legged race, egg & spoon and a tug-of-war competition. 

The afternoon will commence with a toast to her Majesty, then a local photographer will be on hand to record the day by taking a giant group photograph of all the villagers – this we hope will be framed & displayed alongside others in the village hall. 

After lunch the afternoon’s races will begin.  These are not just for the young but we hope the young-at-heart too!  So, get practising your three-legged skills, your egg balancing and of course why not get a tug-of-war team together.  Medals will be presented to the winners.

Whilst we are in the presenting mood, all village children 16 and under will be presented with a memento of the day in the form of a commemorative china mug.  A very limited edition of these Jubilee mugs have been produced and they will not be available at any other time.

There will of course be a raffle – well it wouldn’t really be a village event without a raffle, would it!

During May you will receive an invitation with a tear-off form to be returned to Ann at 2 Church Walk, Little Gransden by 14 May.  We will exchange your slip for the correct number of tickets. (If we are not home pop your slip through the letterbox and we will deliver your tickets.)

If you have friends or family visiting you who do not live in Little Gransden they too are welcome to join us but we ask you to buy them a ticket for £5.00 each, to cover the cost of their barbeque lunch – our budget is tiny and cannot stretch to any ‘extras’.

Everyone on the Jubilee committee has given their time and efforts freely to make this event a success for everyone, so do come along and join in with the spirit of the day. 

See you on the 4^th June.

Parish Council Elections 2012

Parish Council Elections 3 May 2012

Could you be a parish councillor? Elections are held every four years – here is your chance to play a major part in your community! For more details of what is involved speak one of our councilors, or to the Clerk who will also have nomination forms.

Electricity monitoring meters

Electricity monitoring meters are still available to households in Little Gransden. It is only by using these free meters (supplied by South Cambridgeshire Council SPEP group) that you can find out when your electricity costs are highest. Then you can think about a solution to offset the electricity cost rises. Contact Trevor Brown to borrow one.

Thermal imaging camera:

A donation of £70 was made to the Cambridge Carbon Footprint organisation, who owned the camera, and loaned it to the LGEG in return for a donation.  All the money donated by householders was passed on the Cambridge Carbon Footprint without any deduction for "expenses".  The loan of the camera was organised by the SPEP group within South Cambs District Council.

The thermal imaging camera showed up heat losses from concrete lintels over windows, where older buildings had lintels that bridged the cavity.  It showed the heat loss around the edges of some double glazed window panes, where the aluminium spacer between the two sheets of glass conducted heat from inside to outside.  The new "A" rated double glazing windows have an insulated spacer, instead of aluminium, as well as modified glass that reflects heat back into the building.  The camera detected heat being lost though air vents that were open, which they have to be open at times to allow adequate ventilation.  An example of the old style "Crittal" metal window frames revealed how much heat was conducted to the outside through the metal frames - such frames should be replaced as a matter of urgency!

The thermal camera detected heat losses around the outside edges of some houses with under floor heating, and the size and shape of radiators inside poorly insulated walls (mainly wattle and daub construction).  Wood burning stoves and AGA stoves can appear to have considerable heat losses up the chimney stack due to exterior surface temperatures between 20 and 30 deg C on the chimney, when the air temperature was only 4 to 7 deg C at the time of measurement.

In the Little Gransden Village Hall, the warm air rising from the convector heater resulted in air at 33 deg C at ceiling height when the room thermostat was set at 21 deg C.  Cold draughts of around 9 deg C were entering from poorly insulated ceiling at 11 deg C in the stage area and the Committee Room.  Aran Services are being employed to insulate the ceiling above the stage area.  Although the ceiling of the Reception Area is insulated, there is no insulation above the loft floor, and the loft space is open to the atmosphere around the edges of the corrugated roof and wall panels.  This cold air was descending into the Main Hall by the loft door that could not be shut fully - this has now been rectified as a matter of urgency!  In the kitchen of the Village Hall, there had been a damp area in one corner that started to show signs of mould.  This area is a cold spot and immediately above the hot water boiler.  The mould has now been removed, but better insulation and ventilation when water is being boiled, is required.

The Solar Photovoltaic Panels at 15 Main Road have now generated just over 1272 kWh of electricity since they were installed on 28th May, and 9th January.  Unsurprisingly, the many cloudy and short days has resulted in low amounts of electricity being generated in the last month.  Daily generation from only 0.15 kWh to 4.47 kWh were recorded over the Christmas to New Year period.
