Just had out 3rd Carbon Survey, conducted by Paul Reading (www. reddingweb.co.uk ).
Targets and opportunities to look at this time are:
- Staff and Customer Energy Management awareness
- Monitoring and Targeting
- Reduce Energy for Catering Operations
- Heating Control Improvements
- Variable Speed Drives for pumps
- Consider CHP
- Solar Energy Options
1. Staff training is always a good thing and should permanently be on these reports to remind us that it is the people who waste energy not equipment!
2. We already have a target of 50% on our 2005 energy usage levels, and calculate against turnover, activity levels etc… Monitoring would be much easier though if “networked data loggers” were cheaper!
3. The Catering side can be responsible for large amounts of energy wastage, so more training and monitoring needs to be implemented here.
4. Heating control improvements, we are just looking at replacing our existing system with a better system at the moment.
5. Variable Speed Drive for Pumps (VSD); talk of the devil! Just after the inspection a couple of our pumps failed (2HP) and we were going to swap them for VSD pumps. However, when you work out the cost and consider the fact that they are small 2hp the payback time was ludicrously long! Sop the option failed the economic test!
6. Combined Heat and Power (CHP); I am really up for this but we recently changed our water heaters for brand new Lochinvar 98% efficient units. Shame, I really wanted to produce our own electricity.
7. Solar Energy options; the solar system needs a better control system, which we are looking into at the moment.
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.
Just received the Carbon Trust report we had our inspection in mid-May. We now have an action plan of things we need to tackle:
1. A Staff awareness programme. UPDATED Done October 2006
2. Installation of Optimum Stop Star Heating Control. UPDATED We have delayed this as we already zone by heating pump and have a similar manual system already. Due to the dimensions of the building some parts can be cold and hot at the same time on the same day due to wind of the sea and direct sunshine. We are looking for a more optimal solution.
3. Swimming Pool Heating Recuperation. UPDATED Unfortunately I was away on the day this are was inspected, unfortunately the consultant did not recognise the equipment as it is state of the art and already does this function.
4. Swimming pool RH control by dehumidification. UPDATED Unfortunately I was away on the day this are was inspected, unfortunately the consultant did not recognise the equipment as it is state of the art and already does this function.
5. Insulate Hot Pipe work. UPDATED Done October 2006
We have just received our confirmation that our organisation qualifies to receive energy efficiency support from the Carbon Trust. Lets hope they send the right person. ; after all if you can’t do you generally consult!
We filled in an on-line Carbon Trust application today at http://www.thecarbontrust.co.uk/energy/pages/site_survey_application.asp
The form was relatively simple to complete. I would suggest that if your organisation asks for a survey that you mention that you would like a consultant with knowledge of heat exchange principles, heat pumps, thermal storage, solar hot water and gray water recycling.
