Sustainability at the NLAWorld Environment Day, 5th June 2014Jennifer Lloyd

Good morningToday is World Environment Day and we thought this a good opportunity to talk with staff about the sustainability initiatives that the Library has been implementing to become more sustainable.1

What is sustainability?Not being harmful to the environment or depleting natural resources, and thereby supporting long-term ecological balance.

Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirement of present and future generations.

Sustainability is a bit of a buzz word these days and is used in all sorts of ways.

Generally speaking, sustainability is about not being harmful to the environment or depleting natural resources, and thereby supporting long-term ecological balance.

Another definition is that sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirement of present and future generations.

These definitions are very wholistic and I can hear you thinking about what this really means

Use less energy (electricity and gas)Use less waterUse less paperReduce consumption of goodsRecycle and re-use

What does this really mean?

Sustainability in the Library focusses on reducing our use of resources such as electricity, gas, water and paper and reducing the amount of material that we send to landfill by recycling as much as possible.3

Use less energy

The electricity saved by the Library so far in 2013/14 is enough to power the MCG lights for 117 football matches

The amount of electricity saved over the past two years was enough to run an average house with four people in it for 90 years

In 2011 The Library decided to set a target of reducing energy usage in the Library. The target wet was a 10% reduction over three years.This graph shows the electricity and gas usage in the Library over the past three years. The purple column is the current year, which is not yet finished.Click 1 - Based on the year to date figures for this year, the Library will meet, and probably exceed, the targets set. This is a great achievement for the Library. You can see the trends are all downward.

Click 2 - To help give you some perspective on this, the amount of electricity saved by the Library so far this year was enough to power the MCG lights for 117 football matches.

Click 3 - Alternatively, the amount of electricity saved over the past two years was enough to run an average house with four people in it for 90 years.

Turned off equipment when not usedReplaced inefficient equipmentServiced equipment regularlyMeasured energy used for building works

Recycling plastic saves twice as much energy as burning it in an incinerator.Insulated windows in stack areas

How did we do this?

You may be wondering how we managed to achieve this great saving in energy.The answer is a mixture of different things including:Turning off equipment when not in useReplacing inefficient equipmentServicing equipment so it runs efficientlyMeasuring energy used for building works so we better understand the impactsInsulating windows in the stack areas5

Window insulation

..in stack areas

We have also installed window insulation panels in the stack areas on Level 2. These reduce the amount of heat entering the building in summer, and the amount leaving the building in winter. They also stop the draughts!

The aim of these panels is to reduce the amount of energy used by the heating and cooling systems. It has the added benefit of stopping sunlight in the collection area.6

How did we do this?

And perhaps most importantly the Library has actively monitored the timing schedules for our air conditioning systems so that it is only running when we need it to.

Air conditioning trialsControlling temperature and humidity uses a lot of energyThe climate in Canberra is quite stable Using passive storage insulated buildingUsing thermal mass of paper in storage areasStorage spaces generally kept at 19 - 21C and 40 50% RH

One of the major contributors to our energy savings has been the change in the way we operate the Hume Repository and the Hume Annexe.

Storing collections in 24 hour air conditioning uses a lot of energy. In Canberra the climate is quite stable and we certainly dont have high humidity problems like our northern friends. The storage facilities are very large and contain a lot of paper. The insulation in the buildings, and the amount of paper in them, provides a thermal mass that is very slow to release and take on moisture. The buildings change temperature very slowly.

The Library undertook a trial to find out whether the generally accepted storage conditions of 19-21 degrees and 40-50% relative humidity could be maintained in a way that was cheaper.

The trial involved turning off the air conditioning at the Hume Repository.10

Data loggers were placed inside hollowed out books.

Temperature and humidity at the Hume Repository with no energy being used on air conditioning in stack areas

In order to find out what was happening with the temperature and humidity during the trial, Preservation Services put several data loggers into the Hume Repository.

1 Click - The data loggers were placed inside books, inside boxes and 2 Click - on open shelves.

This graph shows the readings from just two of the data loggers. 3 Click - The Humidity levels are the top lines4 Click and the temperature are the bottom lines

5 Click you can see that the humidity readings inside the book (in blue)6 Click are much more stable that the readings taken on a shelf, or not inside a book (in green)the temperature is also more stable, and you can see how the building gradually warmed up from October to December from about 15 degrees to 20 degrees7 Click the preferred temperature and humidity levels are shown here by the black lines. Notice that the blue humidity line stays within these lines inside the book.The temperature is colder than preferred but the books dont mind if it is colder, only people mind.11

Air conditioning trialsControlling temperature and humidity uses a lot of energyThe climate in Canberra is quite stable Using passive storage insulated buildingUsing thermal mass of paper in storage areasStorage spaces generally kept at 19 - 21C and 40 50% RHHume Repository and Annexe stack areas are now turned off (except for some heating in winter for staff)

As a result of these and other tests, the air conditioning at the Hume Repository and Hume Annexe is now turned off, except for a small amount of heating in winter for staff comfort. This saves the Library a tremendous amount of energy, and money.

Futher trials will be conducted this year on spaces within the Parkes building.12

Use less water

Water meters replaced twice in 2012

Unfortunately the Library hasnt been able to do so well with reducing water usage. The ACTEWAGL water meter has been replaced twice in 2012 due to a fault. This means that the water usage was estimated by ACTEWAGL so the figures reported here are not actual figures, but they are all weve got. This graph shows the water usage increasing over the past three years, and exceeding the targets that were set.

Future statistics will be more reliable.13

Use less paper

Saved 187 trees

Print double sidedOnly print what you needUse recycled paperReduce colour printing

The Library uses lots of paper each year last year we used 512 trees worth of paper. This usage is decreasing though, as you can see by this graph.

The introduction of our new Multi Functional Devices in January has seen a rapid decrease in the use of paper. This is probably because we now have to scan our pass to get the printer to print for us.

Click 1 Last year the Library saved 187 trees by reducing paper consumption

Each month, about 4000 sheets of paper are not printed, even though they were sent to the printer. Thats more than one tree a month that we dont use.

Click 2 - The things you can do to reduce the amount of paper used is to print double sided as much as possible, only print what you need and use recycled paper. The modern equipment operates very well with recycled paper. You can also reduce the amount of colour printing you do.
