Today we finally received 250 2.5w 60 LED GU10 bulbs. 185 are for the corridors of the Health Club and Spa Treatments; these corridors are lit for 15 hours per day, each bulb was a 50watt halogen; this equates to around 22 tonnes of CO2 per year (about 2 average households) and they cost £5600 per annum in electricity costs.
The LED replacement bulbs cost roughly £6 each and the cost of fitting each bulb with various adapters is around £8 giving a total cost to replace these 185 bulbs of roughly £2500. Fortunately these replacement bulbs are 3watt each (considerably less than 50watt), they will still be on 15 hours per day but will now produce only 1.31 tonnes of Co2 and cost around £350 per year to have lit. We got these bulbs from Graham Smith of Future Green Light on Ebay shops.
Today we received 2 large ROJEK wood burning boilers at 49.5 KW weighing 500 kg each. We have bought these to assist in heating and hot water for the hotel at 100kw’s they are rather powerful as they give this output all the time as long as they are kept fed with wood every 5 hours. Unlike a gas boilers you can not turn them off so they basically operate at a lesser degree of flexibility so you need some large vessels to store all the hot water produced. Fortunately we have just the thing in the accumulator tanks. The aim is to use this heat to supply the hotel and test the theory and principle of attempting to run a hotel this size with some green energy. Incidentally we got the boilers from http://www.axminster.co.uk/shop-Rojek.htm the delivery and service have been very good.
UPDATED April 2009; We have not as yet fitted these boilers we are somewhat behind a little; such is life. We are having trouble finding a place that is not too far away where we can fit the 5000l accumulator; these things are very big!
Today I have finally ordered LED lights for the hotel; having proved the concept at home I have finally found lights with an acceptable brightness and Kelvin in LED.
So I have ordered the LED bulbs for the Spa. There are presently 185 of them in total lit for 15 hours per day, each bulb is a 50watt halogen; this equates to around 22 tonnes of CO2 per year (about 2 average households) and they cost £5600 per annum in electricity costs.
The replacement bulbs I have ordered are LED and I have managed to get them for £5.80 each and the cost of fitting each bulb with various adapters is around £8 giving a total cost to replace these 185 bulbs of roughly £2500. Fortunately these replacement bulbs are 3watt each (considerably less than 50watt), they will still be on 15 hours per day but will now produce only 1.31 tonnes of Co2 and cost around £350 per year to have lit.
So you can be green and be making economically sound decisions at the same time!
Today we sent the laundry back to Sunlight, why? Well because we were very conscious of the environmental impact of the the lorry to Durham and back 5 days per week with our laundry. I have performed very through calculations and I hope they are right or else I will be eating a large helping of humble pie!
UPDATED January 2009; I now have one full months worth of meter readings for the laundry and I have made extrapolation calculations below, so it looks like no humble pie for myself.
- the Sunlight lorry traveled 180 miles (290 257.5Km) round trip in lorry which produced 272kgs of CO2 per trip with 260 trips per year giving a total CO2 output of 70 metric tonnes of fossil fuel derived Co2 per annum.
*Assumption for diesel fuel 2.68 kg’s of CO2 per litre diesel consumed and a lorry consumes roughly 0.35 litres per kilometre traveled.
The new laundry consumes
15m3 fresh water per month 300m3 or 23kg’s fossil fuel derived Co2 per year (though this should vastly decrease by 70% when the gray water system is installed)
The laundry equipment consumes 1500 m3 of gas per month or 39 metric tonnes fossil fuel derived Co2 per year (though this should decrease by 50% when the wood burning boilers are installed)
The laundry uses roughly 96Kwhrs of electricity per day for 365days per year or 15 metric tonnes fossil fuel derived Co2 per year.
Therefore roughly laundry fossil fuel derived Co2 produced as now 54 metric tonnes of Co2 per annum. Saving roughly 16 metric tonnes of co2 per year (1.75 households).
When wood burning boilers installed fossil fuel produced as now 35 metric tonnes of Co2 per annum. Saving roughly 35 metric tonnes Co2 per year (3.5 households).
Additional plus points
- 3 full time jobs for the local economy.
- Better quality linen can be used.
- Financially the project breaks even after 18months, allowing for reserves to be accumulated to replace equipment as required after 3 years.
- Managed to recover 2 extra bedrooms from old linen stores as we had to store more linen in the previous scenario.
Today fitted the new wood burning stove for the hotel foyer, it is 18Kw’s in power and looks very nice indeed, now we can dispose of the un-reclaimable wood from the refurbishment works and reduce our dependence on fossil fuels.
UPDATED January 2009; one problem with this burner is that the rooms above are now too hot! Can you believe it! Yes, the radiators now have to be turned off in the rooms above.
Today we applied for the solar panel on the roof (fingers crossed), in order to do this I have extracted some data and updated our Green Policy in agreement with our “Green Team”.
Our main aims are Reduce, Reuse, Recycle, Free Cycle and lastly Carbon Offset.
Our KG Co2 for the last 4 years is below;
2006 909,000 KG -10 % reasons; various actions
2007 809,000 KG -12% reasons; master switches
2008 767,439 KG – 5% Reasons; various reasons LED lights some but mostly change in behaviour
In the 12 months to end of October this year we have reduced KG’C02 produced by 42,000 KG’s.
We have been really pleased with this achievement as it equates to a 5% reduction in year on year, this is after already introducing in previous years low energy lighting, efficient boilers (that can run at 450c) and master switches for guest bedrooms.
During recent months we have been identifying are consuming the most energy, this has been tied down to areas where the lighting is on for 8 hours or more per day. Our solution has been to look towards LED lighting solutions. We have replaced a large number of 12v 50Watt halogen lights with 48 LED and 60LED lights, these lights use 1.5 and 2.5 watts for the equivalent light output and last on average 20000 hours, though they do cost around £3.5 to £5.00 per bulb. These bulbs pay for themselves with running costs in 4 months; the only main problem encountered is that choosing a light with a direct warmth and light output replacement takes a lot of research, but research that is worth it.
We have also noted that when the Halogen lights are replaced less heat is produced meaning that the air conditioning does not need to be on anywhere near as much.
The above graph on first view does not show much difference but overall the biggest single gain is the room power master switches fitted in June 2007, along with the behavioural changes from the hotel team.
Today I received £250 of LED lights from China for home, they are in various forms GU10 60 LED, BC22 (uk bulb Fitting 48 LED). I have done a calculation on the energy consumption below for my kitchen.
I have 20 50 watt GU10 bulbs in my kitchen on for around 6 hours a day which costs £220 per annum; I have changed these for 20 48LED 2.5 watt bulbs at a total cost of £120 these and they would cost £10.95 per year to run; pay back is 7 months!
No brainier; the bulbs on a bench test seem to use between 2.5W to 3W depending on which bulb, is this the future of lighting; changing them is a doodle as LED’s run cold though you need to let the fitting which had the halogen bulb in cool down first or they will not light up immediately!
UPDATED November 2008; I was in B&Q today and they have also started selling LED lights not as bright as the ones from China but it is a start.
I Bought 5 more effergy meters today for the lead management team £36 each. Basically it is a meter that measures the amount of electricity consumed in either Kw hr’s, Co2, Max Power usage etc… The best bit is the power alarm, basically the alarm goes off at 5KW’s.
UPDATED September 2008; the team have really benefited from these meters, my own electric bill recently landed on the door step and it has reduced from £185 for August quarter 2007 to £89 August 2008 quarter end. The alarm works the best as we learnt early on the you either had the choice of the dishwasher or tumble dryer on at the same time as boiling the kettle. We regularly run at less than 500 watts now I have fitted the LED lights in the house. The really interesting thing is that the management team wail not give me back the meters either; as they have had similar results to myself.
UPDATED August 2009 Over the last year I have bought around £350 of these excellent devices for the crew.
What is it I hear you say, it is well I highly recommend it.
THE GREEN TOURISM BUSINESS SCHEME
The Green Tourism Business Scheme, has been running since 1997 and with over 1400 members across the whole of the UK, it is the largest and most established scheme of its type in the World. In Scotland the GTBS was developed in partnership with Visit Scotland and it is recognized by UK national and regional government as a crucial part of its drive towards sustainability. Our aim is to build on this strong position and ensure that the UK remains at the forefront of sustainable tourism in the future.
Levels of Success?
There are three levels of award Bronze, Silver and Gold; needless to say we are aiming for Gold.
UPDATED August 2009, just got gold!
I received our second Carbon Trust report today, the consultant Paul Redding of Redding Associates was very good he definitely knew his stuff. We now have a good action plan for reducing our carbon emissions.
1. We need to implement a recurring staff training, reminding and enforcing policy for environmental awareness on a roll out plan. DONE March 2008, we have improved on what we already had.
2. We will be switching off the 25 computers at night which used to consume 80 watts or produce 5 tonnes of CO2 per year, we have now fitted a central master switch for each set of computers. DONE March 2008, I bought some town extension unist and this has worked well. UPDATED September 2008, I am now putting these on other low draw electrical items.
3. Install high frequency lighting retrofits for the fluorescent lighting; in fact we are getting rid of then for LED lights! UPDATED September 2008, I have done this where possible, but also looking for a longer term LED solution.
4. Have a good look at what is left on powered up for 11 hours plus a day, it turns out most of the lighting is left on so we will be changing to LED and turning them off. UPDATED June 2008 Just started fitting them!
4. Fit variable speed controls for the pool pumps, this we have done as just a week after the report the 1st pump failed then 3 weeks later the back up pump failed. Such is fate. DONE March 2009, just fitted the first ones as the old ones failed.
