Lighting improvements in toilets

One project that has been undertaken by Mike Riley’s team at Estates and Buildings is to adjust the Passive Infrared Sensors (PIRs) in the toilets so that now the lights come on only when you enter a cubicle rather than as you pass by.

There are more lighting projects in the offing (see the list of projects and the POE report), including the lights in the some of the coffee areas that never go out.

And although we don’t have control over all lights in the building, we can help by turning off office and meeting room lights when leaving.

Action arising from post occupancy evaluation

Executive summary: there are a number of projects either underway or under discussion to reduce energy consumption in the Forum and improve the comfort of its occupants. The  notes of the latest Post Occupancy Evaluation meeting explain some of the thinking behind the list.

For the longer story, read on…

Post Occupancy Evaluation (POE)  is, according to Preiser et &al., cited in Wikipedia,

the process of evaluating buildings in a systematic and rigorous manner after they have been built and occupied for some time.

In a presentation at the Mainstreaming POE meeting at the Lighthouse, Glasgow in 2009, Bill Bordass and Adrian Leaman propose that the main key questions addressed by POE are:

1. How is this building working?
2. What do people think about it?
3. How does this relate to client and design intent?
4. How can this building be improved?
5. How can future buildings be improved?

The presentation gives examples of buildings that do not perform as designed,  demonstrating the importance of  POE.

What’s this to do with us? The same Bill Bordass has been undertaking a POE of the Potterrow Development (i.e. the Informatics Forum and Dugald Stewart Building) for the University and Bennetts Associates, the Forum’s architects. You may remember filling in a questionnaire in July 2011 about your perception of the building. The responses to this survey, and other data will be presented in the report.

In the process or writing the report, Bill Bordass has had a number of meetings with staff from Estates & Buildings, Informatics and PPLS. At these meetings several energy-saving and comfort-improving ideas have been discussed and actions have been agreed on, as detailed in the notes of the last POE meeting. Bill’s contributed his understanding, gleaned from years of experience of investigating buildings, of how the heating and ventilation in the Forum work in practice. He’s also put forward some new ideas and helped to refine some which had already been discussed by Informatics and E&B people, as summarised in the Informatics Energy report. Gratifyingly, the results of our in-house comfort survey have complemented the survey run by Bill.

Heating and space temperature standards

I know from the comfort survey that many occupants of the Forum feel too cold in Winter. However, if you are lucky enough to have an office that is warm enough, please bear in mind the Energy Office’s request to not overheat your office.

If you do feel too cold (or hot), then take a look at the Energy Office’s advice. One link from that page is to the University’s current Space Temperature Standards.  Among other things, I didn’t know that:

The University aims to provide a working room temperature of 20-21°C in academic and administrative areas during the heating season (mid September through to early May)

If you’d like to order a thermometer, please email Shona Buchanan in the Energy Office.

Quality Bike Corridor articles (featuring the Forum)

Those who commute to the Forum on two wheels will probably  have already experienced the improvements to the bike lanes from George IV Bridge to King’s Buildings. I noticed that council’s announcement about this “Quality Bike Corridor” and this article in The Times were both illustrated by pictures with the Forum as a backdrop – quite a dramatic one in the The Times. The council’s photo also features in the interesting analysis by Spokes of the possible effect of the improvements on cycle commuting numbers.

Update: the Quality Bike Corridor has been disucussed on the  CityCyclingEdinburgh Forum. A fair summary of the conclusion comes from this quote from “cc” (who he?):

Overall it’s positive. It’s just several orders of magnitude less positive than it could have been.

Nature article: Be persuasive. Be brave. Be arrested (if necessary)

This viewpoint article by financier Jeremy Grantham in  Nature seems pertinent to this blog. In argues that scientists should be more outspoken about the dangers of climate change:

It is crucial that scientists take more career risks and sound a more realistic, more desperate, note on the global-warming problem. Younger scientists are obsessed by thoughts of tenure, so it is probably up to older, senior and retired scientists to do the heavy lifting. Be arrested if necessary. This is not only the crisis of your lives — it is also the crisis of our species’ existence. I implore you to be brave.

There is also some concerning stuff about fertiliser depletion.

Comfort survey results

Here’s another report – this time on the results of the Comfort Survey, which 106 of you kindly filled in. The statistics will probably not be too much of a surprise to anyone in the Forum – some rooms are too hot in general and some are too cold in the Winter. A majority of respondents found the air to be too stuffy in the Summer. The raw data has been used to inform Bill Bordass’s investigations of the building and should inform any tweaks to the building’s ventilation or heating in the future.

In case you’re wondering about the format of the report, it was created from the dataset using R and Sweave.

Report on reducing energy consumption in the Forum

After too long a delay, here is the Informatics Energy Report on what I’ve discovered about energy use in the Forum and what other willing colleauges have been doing to help reduce it. The executive summary is that since April energy use has been is down by around 15% on the corresponding month in 2011. Some of this is due to improving the control of ventilation in the Forum and some is due to reductions in desktop computer and office appliance use.

I’m very aware that there is more to do – not least the lights permanently on in the kitchen areas. Hopefully there will  be progress to report on this and other areas before too long.

New energy display – comments welcome

I’m afraid that the first half of the year has vanished without me even getting round to writing up an analysis of the energy use over Christmas, as promised. I will try to do this later, but for now, here’s a link to a live display of the Forum’s energy use.

Hopefully this is going to be displayed on the screen at the entrance of the Forum. I think a few tweaks to the alignment of the graphs would be good – any comments you have would be welcome. I’ll pass them on to Dougie Williams from Estates and Buildings, who has been working with various schools to get similar displays installed.

It looks as though we’ve been using at least 10% less energy in the past few months than we did at this time last year.

Crimbo click – how low can we go?

You’ve probably heard the energy-saving message to turn off any equipment that isn’t going to be used over the Christmas and New Year vacation, including desktop machines and monitors.

Using the University’s energy monitoring system, we’ll be able to see how much energy we save. Last year the Informatics Forum used about 20% less energy in a week during the vacation than in a “typical” week. After the vacation, I’ll do a similar analysis to get this year’s savings.

This year, we’ll be able to see even more clearly how much energy we’re saving. Almost all the power sockets in offices are supplied via a UPS system, which allows us to monitor how much energy is used by office appliances such as computers, monitors and heaters (but not lighting). A typical week looks like this:

If we cut all of this, that would be a total of roughly 15,800kWh over the 11 days of the vacation or £1423 or approximately 7.9 tonnes of CO2. Of course, we’re not going to manage that – some people will be coming and others have simulations to run – but how low can we go?

P.S. If you’ve gone already and think you don’t need your machine on, you
can ssh in and shut down like this:
ssh ssh.inf.ed.ac.uk
ssh {your computer's name}
# Check no-one else is logged in
users
halt

You may need to check that no cron jobs are running – my machine at least appears to wake (even after a halt) when a cron job is imminent.

P.P.S. You may be wondering if we could use the UPS data to produce a breakdown of Informatics Forum energy use. We can; I’ll blog about that in the New Year when I’ve not got multiple deadlines!

Touchscreen improvements

A number of people have commented that there is a certain irony in the touchscreens being on late at night, displaying messages asking us to turn off screens. I passed on these comments to Ian Durkacz, who looks after the touchscreens, asking if  it would it be possible to have the screensavers set to come on only in the day time. Ian writes:

Now that the necessary changes have worked their way through our release system, I have changed the setup of the touchscreens so that:

  • during business hours (currently declared to be 8:30 to 17:30, but easily changed) the current screensaver will be in effect;
  • outside business hours, the screensaver will just be a blank screen.

This should all be active now. Any problems or comments, let me know.

I regard this as a ‘temporary’ fix; the final plan will be to have the touchscreen machines truly *sleeping* outside of business hours, but wakeable at  the touch of a screen. I *think* that this should be possible, but there are a  few related things to get sorted out first.

Anyway, I hope the current change reduces the confusion caused by the touchscreens actively displaying ‘please turn off your monitor’ messages at 3am in the morning …

Note that I have exempted the ground floor touchscreen from all of this handling: it’s a special case.

Thanks to Ian for working on this.
