Sustainabledmu week #3 | 15th – 20th of october 2012

Look what happened on @SustainableDMU Twitter account last week! We started approaching the issue of energy use, and in particular of electricity in DMU’s buildings. In addition, we tried to explain the links between our actions and the energy consumption that they cause.

We also had a very interesting conversation about the efficiency of the kettle and the constant hot boiler tap for making tea and coffee. We tried to explain it theoretically, but then one of our Twitter friends suggested to run an experiment using one week the Hot tap and the week later the Kettle. So we organised the competition that is going to start next week in the IESD department. Follow the #kettleVShotTap hashtag on Twitter for updates.

There also was an issue with lights left on in the Queens Building, that looks like they were only lighting some bricks… One of our friends pointed that out to the attention of SustainableDMU [that is, the sustainability team @DMU]. In this way the problem was reported to the DMU estate. The idea of opening a Twitter account is precisely to encourage a discussion about environmental issues at DMU; so if you notice anything you don’t know if it’s functioning in the right way, it is the perfect place to do it. In parallel with the traditional channels of course.

These the main topics of last week. I am waiting for you next week where we will be talking about the heating and air conditioning issue. Hope to hear from you! Have a good Sunday evening!

    @SustainableDMU how much better than a kettle are the constant water boilers that some buildings e.g. EMS have?
    Tue, Oct 16 2012 05:19:29
  16. This was the reply:

    @simple_salmon I had a chat with @IESD researchers yesterday and the question kettle vs constant hot water boiler is not so easy to solve.

    The problem is that it’s a mix of technological and behavioural evaluation that will lead to an answer. However, thanks to @kakuiyibo we had a clear explanation of the problem.

    The first reason a water boiler is more efficient is that it uses gas to heat up the water,and in England gas is cheaper than electricity.However,it all depends on the demand, that is the number of cups of tea your preparing each day.

    It is almost sure a boiler is not more efficient for a household,where the demands of cups of tea is quite low. In an office on the other hand the demand of cup of tea can be quite high,depending on the number of people,therefore making the boiler more convenient both from a financial and environmental point of view. You can have a look at this Moreover, people won’t have to wait for their water to be hot, and this can be in an office a strong motivation for the boiler too. Hope it was clear!

    @SustainableDMU could you explain it again? I’m kidding 🙂 that was great thanks.

    @c3iq @simple_salmon It would be really nice to conduct an experiment!We need an office with at least 40cups of tea/day,that is 10/15people

    @c3iq @simple_salmon Ok we can try to ask them if they like to participate.We’ll also send a tweet to see if anyone else is happy to do it!

    @snapey1979 Thanks for highlighting this. Will look into it.

  37. snapey1979
    @SustainableDMU no problem. Not your fault, just so, so hard to change and make it stick.
    Thu, Oct 18 2012 02:57:46
  38. SustainableDMU
    @snapey1979 Lights are being worked on and should light up walkways so will get adjusted. The lights are controlled by presence detectors.

  39. snapey1979
    @SustainableDMU Thanks, but light above door cannot light anything other than bricks (no adjustment in that axis). Wasn’t on yesterday…

    @snapey1979 Lights will be adjusted shortly, thanks for raising this. If you spot anything else please do let us know. Thks again

    @the_markness physical or metaphysical?
    Thu, Oct 18 2012 03:41:23
  43. the_markness
    @c3iq In this case physical tables. Is the metaphysical quantifiable? I’d be interested to see the charts.

    @c3iq @the_markness We have a furniture store for unwanted pieces of furniture that can be re-used by others at #DMU if in good condition.

    @SustainableDMU @c3iq That’s precisely what I’m up to. One persons rubbish is another’s treasure and all that.

    Unsure of how much energy are you appliances at home using when in stand by?! I usually am but I found this
    Thu, Oct 18 2012 06:30:18
  47. ParenRaval
    @SustainableDMU We tend to switch off many devices when not in use now. Also really impressed with how little our server room consumes too.
    Thu, Oct 18 2012 06:36:48
  48. SustainableDMU
    @ParenRaval This is really a good habit to have! Well done!

  53. SustainableDMU
    IESD had the metering system already set up, and they were waiting for the good opportunity to test it! @c3iq @simple_salmon

    You can measure your Ecological Footprint on the #DMU and #WWF footprint calculator What’s your footprint in planets?
    Fri, Oct 19 2012 05:07:08
  61. davidnaylor
    @SustainableDMU Just a point re: the calculator – nowhere for under 17s – doesn’t take into account footprint of having young children.
    Fri, Oct 19 2012 05:16:57
  62. SustainableDMU
    @davidnaylor Check out the FAQs. Taken view that children under 17 aren’t responsible for their own footprint.
    Fri, Oct 19 2012 05:39:34
  63. davidnaylor
    @SustainableDMU That’s fair enough, I approached the calculator from a family perspective (2 adults & a 4 year old) all costs/usage
    Fri, Oct 19 2012 05:41:33
  64. SustainableDMU
    An other week went by, time for weekend! Have a good one! Remember to switch off computer,equipment & lights when you leave! #DMU #dmuenergy
