Year to 31st October 2010. How did we do?

In previous years our values for CO2 produced were

2005 1005471
2006 909004 10%
2007 808851 11%
2008 767439 5%
2009 767035 0%
2010 781315 -2%

In the last year our KG CO2 has increased 2%.

Now this might look bad on the face of it without any other information, we have done all this work on efficiency and then “balls it up” in 2010.

But what has happened is that the total room stock has risen from an average of 86 rooms for 2009 to 115 for 2010, a rise of 34%, whilst room occupancy has kept steady. So we have had 30% increased activity but only increased our CO2 from fossil fuels by 2.5%.

This masked the real work we did last year in investment in staff training and plant and equipment.

So overall I am quite chuffed.

VO or Voltage Optimisation, to do or not to do?

VO or Voltage Optimisation, to do or not to do?

Basically VO (Voltage Optimisation) is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage ‘optimisation’ devices merely reduce the voltage using a transformer, others give the end-user the ability to control and optimise their electricity supply locally, correcting voltage and power quality problems from the grid, and are designed to do so very efficiently. Voltage optimisation systems are typically installed in series with the mains electrical supply to a building, allowing all its electrical equipment to benefit from an optimised supply.

In the UK, where there is a particular problem with over-voltage, voltage optimisation as an energy conservation is growing rapidly in popularity.

So what does all that mean, well basically if you have 3Phase AC Motors, Lighting (fluorescent), electrical heaters you can get savings of 8%+, for a quite considerable investment (£40-50K+).

Is this any good for us, I have now had two decent consultants (whom I know personally, so trust their opinion) and they are in agreement with myself, VO will not benefit a property with mainly LED lighting, no electrical heaters.

Localised VO units fitted to a supply which directly feeds say for example a fluorescent lighting circuit in the gym (soon to be replaced with SMD strip lighting) will be most beneficial, and can be acquired much cheaper that a unit fitted at the main supply input; these smaller units can be bought for £2-3K each.

URGENT – This is not a circular, CRC (Carbon Reduction Commitment ESS Scheme)

I got this email below today

You should have been receiving correspondence from the Environment Agency in relation to the Carbon Reduction Commitment ESS Scheme. The deadline of 30th September 2010 is fast approaching for all organisations with Half Hourly Metered Electricity supplies to complete their online registration. Please note that should you miss this deadline the penalty may be invoked of £5,000 fine imposed immediately with a further £500 per working day to a maximum of 80 working days. Based on the Half Hourly meters that TEBL administer contracts on your behalf, we believe that you are to register as an Information Declarer. You are required to only declare information and are not a full participant in the scheme. However, please ensure that you look to the highest UK parent organisation and should you believe that based on Calendar 2008 your organisation did use over the 6,000MWh’s of Half Hourly metered usage, then please contact Victoria Clarke ASAP to discuss the options and implications. Please can you look to complete the required registration via the CRC online registry on the Environment Agency Website and confirm by reply once this has been done so that we are able to update our records.

Basically no need to panic, just register on the site and you get a CRC registration number and fill out a form (information disclosure), regarding you energy usage.

Apparently 40% of all hospitality waste is catering waste = expensive waste

I have been monitoring our waste a lot lately and this is not the case for us. I already have trouble getting enough compostable waste out of the kitchens as it is to service my homemade “wormery and composter” (basically a long barrel, with fins in to slowly move the material down to the exit where compost comes out, commercial ones were a lot of money, last quote3 I got was £8K).

Got The All Clear On Public Recycle Bins

A few years ago we installed recycle bins on the corridors for guests to directly recycle their waste, however one thing you need to be aware of before installing anything in you corridors is the remaining width in the corridor after install against the total possible number of people whom may be trying to escape down it. Not looking into this properly lead to the removal of the bins 1 year later after a fire risk assessment.

This resulted in asking the room attendants to recycle what they found as best they can from guests over the interval which has worked quite well and we willcontinue to encourage this.

We have now just bought a smaller and quieter recycling system for each floor.

I say quieter because you also need to consider the noise produced from lifting bins lids and dropping say an empty coke can into the bin late at night.

Direct Transport website?

I met with a journalist last night called Richard Hammond who put me onto a website called http://www.transportdirect.info which allows you to make journeys using a mix of public transport. There is even a cycle route web widget.

I have just put a webwidget on our website, so if you want to calculate the best sustainable route to a destibnation you can.

What KgCO2 are we using per Unit?

I just got a call about this question we are using for electricity 0.43 Kg CO2 per KWhr, for gas 2.2Kg per M3, for water 0.261Kg Co2 per M3.

By the way the latest graphs are below for Kg Co2 we produce from Power, light and heat.

Figures YTD 5 months into financial year

We are 5 months into the financial year, with the best of the weather ahead to really test the solar heating capabilities.

Hopefully the next order of SMD lights will arrive next week.

Solar Panel that is on the roof of the Crown Spa Hotel

What have you been up to lately?

Attended the Y10 conference recently and was asked “what have we been doing on the green front lately?”

We installed the bio-boilers and are now moving them again to a more permanent location in transport container. All is not lost as the old pipe work will be used for the new laundry equipment as the laundry needed to expand with the increase in demand from the hotel business. I am very pleased as it is a good opportunity to install a new 10foot high accumulator which will make the heating system more efficient.

Rainwater harvesting install is going to plan and is already supplying the public toilets with rain water harvested from the roof.

Solar panels, these are producing a lot of hot water and the pool is presently the main benefactor as at this time of year most heat is produced when guests have left their rooms and are exploring the local area, at this time the control system is manually (will be fully automatic shortly) switched over to the pool heating circuit. The gas consumption in the pool area has fallen by 20% in the last month (year on year) for the pool boilers, though overall gas consumption is up in the financial year to date due to the cold weather in January 2010 which resulted in 30% increase in gas consumption that month.

LED lights, I am just about to place another order for LEDs (due to a lot of enquires), we will be shortly selling these items on eBay having satisfied ourselves that our supply’s are good quality. Overall the electricity usage did increase a little overall in January 2010 on prior year (bad weather and gloomy days), I am happy that the total financial year to date consumption is down on last year (again!)

So overall since November 2009 (the start of our financial year) to February 2010 we are

2% up on KG’s CO2 from gas consumption on prior year,

6.5% down on KG’s CO2 from electricity consumption on prior year,

35% down on CO2 from water consumption on prior year,

Resulting in a 2.5% less CO2 from the combined CO2 from power, light, heat and water consumption.

( NB Different types of energy are used to different quantities in the business, our biggest fossil fuel derived CO2 culprit is electricity, then gas then water, so if you really want to make big “inroads” into reduction of fossil fuel derived CO2 just turn the electrical items off when not in use, replace inefficient bulbs and turn that thermostat down!) You do not need to invest in expensive projects until you do the simple stuff that works first!

You also need to consider your own organisations circumstances, requirments and main useage culprits!

Do the Solar pannels work?

Atended the SHA anual ball at the weekend at the Spa, and I got asked the above question. My answer was yes, payback still looks like roughly 8 years. The pannels are providing a great deal of warm water at this time of year (though it has been cloudy lately) but no matter how many pannels you do have the temperature will not get much above 35 oc. Though this does save a lot of energy that would have been used to heat the water from 8oc (ground water temp at the moment) to 28oc (with a heat exchanger due to the specific heat capacity of water, you will normall only get the water to 8oc below the solar temperature).

I am still happy to say 6m3 of water at around 65oc from March to October on every bright day, plus with the pool heat exchanger the lower temperature of 35oc at this time of year is exchanged into the pool as the pool only needs to be around 30oc, very little heat is lost. This has worked so well that we have now taken out the now redundant second boiler to heat the pool water.

Did a talk to the Town Team on Sustainability

Did a talk to the Scarborough “Town Team” last night, I forgot that the town team is concerned with planning, as we have had some discussions over the years with a small minority of people whom want to see the Crown spa Hotel building remain exactly as it was in the “olden days” even if this means it will be a borderline 2 star hotel and run down.

So as I sat down and realised the above I thought “oh crap!” I expected that this was going to be a tough ride, however I was very pleasantly supprised at their reception and the discussions after the meeting. I basically the people at the meeting were not the “minority I have previously encountered. My talk covered the journey from 2005 to the present day and the future plans regarding the enviroment. I explained per the powerpoint what we have done, and took some show and tell items an “Effergy meter” (see below) a simple socket power useage measurer and 50w Halogen bulb, 2W old style LED and 2.5W SMD (a true 50W replacement). Overall it is not until you see the brightness of these lights in real life that you can really see where I am comming from with regard to them.
