Transcipt of Interview between Brian Hunter, METERology and John Kingsland, Utilities Manager, University of Aberdeen.
Brian:Hi, I am joined today by John Kingsland, The Utilities Manager with the University of Aberdeen. Hi John.
John:Hello Brian.
Brian:Thanks for agreeing to do this interview with us and I was wondering if you could maybe start off by telling us a little more about the University of Aberdeen.
John:The Universitiy of Aberdeen is home to 13,500 students and 3,500 staff. It's got a number of main academic buildings, which I think is roughly 30 and the utilities cost for the university, for the academic buildings is £4M.
Brian:£4M per year?
Brian:Wow! That's a big, that's a big utility bill. So that's a lot of energy what was the problem that you had to solve when you were looking for a metering solution?
John:We've got a lot of sub meters on the site both electricity and for heat. We get manual reads month to month but we can't see any fine detail.
Brian:So what were the sort of different types of solutions that you considered?
John:We had a look at the Building Management System to see whether that would handle the data and then we looked at options specifically for collecting half hourly data from meters.
Brian:Did the METERology solution offer specific advantages over the Building Management System?
John:Yes. It was better able to handle the large amounts of data that you are collecting. We have 110 meters connected on the system. That equates to about 2 million data points per year. The system uses a SQL Server database and it handles the amount of data, yes, without any difficulty at all. And it is much better in terms of displaying the information as well.
Brian:Do you have any examples of where this has already made a difference?
John:One that springs to mind is the Queen Mother Library. I found out that the cleaners go in at night and all the floors were being left on. Subsequent to finding this information out we have been able to get the cleaners to turn of part of the floors as they go and this has reduced the nighttime consumption, yielding a saving of about £11,000 per year.
Brian:£11,000 just by switching the lights off as they go?
Brian:That's got to be a good saving, the fact that other than the investment in METERology there is no change to the building itself.
John:That's right.
Brian:Can it be accessed from anywhere in the University?
John:It can be, yes. All you need to do is email the link to somebody who is on the intranet, either staff or student and they can just put the link into their web browser and look up the information.
Brian:So it is being used by the students as well?
John:Yes, some of the information is going to the stsudents as well.
Brian:And how, and what, has been their response?
John:I think they are quite impressed with it. They can now have a check. They can actually see that if they do turn off the lights off at night the consumption does drop.
Brian:And has there been any reaction from any other groups of users?
John:Our electricians have been quite keen on it, because they can now check to see what the peak demand is within a building so that they now whether their system is appropriatey sized for the building.
Brian:And what other benefits are you experiencing from the system?
John:It lends itself to quantifying not just things like switching off lights but if you have changed out light fittings, something like that, in an area you can demonstrate that you've actually made the energy savings that you said you were going to. Because it works on a building level we're able to see it within an individual building, where as previously that definition was lost because it was on the main supply and it was too small a saving to look for at that level.
Brian:How easy is the system to use?
John:The system is very easy to use. I had some input into the setup, and so it puts out the display in a format that I like to see it, particularly on the daily profile, with 48 half hour periods.
Brian:Brilliant. Thanks very much John.
