Sustainable power, light and heat solutions

The Year so Far in Brief

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;

2005 1,005,000KG
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.

Energy CO2 Consumption

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.

We Now Have £100,000 Interest Free Loan!

The Crown Is now in receipt of a £100,000 interest free loan for the solar panels. Trouble is as soon as suppliers realise this the price goes up by more than the actual interest saving. This is very disappointing, I think we will be sourcing and paying for the panels directly from China. UPDATED March 2009 we will not be using the CT interest free loan, this is not the place to go into it but I have found a cheaper supplier whio is not on the approved list.

Solar Tanks Fitted Now where are the Solar Panels?

We have just fitted the solar tanks below the new Spa development. This has cost over £25K in costs and should be enough accumulation tank volume wise for around 100m2 of Solar panels on the roof of either the restaurant or the main roof when we finally develop the 4th floor. These tanks have had to be specially designed due to the space they are fitting in as they will essentially be under ground when fitted and we do not want to be returning to them at a later date. I seems that the real cost has been the Solar heating control mechanism at some £6,000!

Why fit them now? Well we need to develop the Spa Treatements business and sometimes you have to buy the cart before the horse!
