2 There is only ONE planet! Treat the earth well: it was not given to you by your parents, it was loaned to you by your children. We do not inherit the Earth from our ancestors, we borrow it from our children. - Ancient Indian Proverb

3 Do you know that… One office worker can use a quarter ton of materials in a year which includes 10,000 pieces of copier paper? Every 100 reams of recycled paper that is printed double sided saves two trees, more than a ton of greenhouse gases? Computers in the office can burn up to $1 billion worth of electricity annually and that's when they're idling?

4 We spend at least 8 hours a day in our office, and in the process, consuming a large amount of resources - electricity, paper, stationeries, toners, electronic devices and so on. This sustainable-office guide seeks to show you how you can do your bit for the environment from where you spend most of your day, that is in the office!

7 Do you know? Recycled paper uses 50% less energy, up to 75% less water and generates about 90% less wastewater than producing paper from virgin timber.

8 For every 150 reams of paper with 70% recycled content, we can save 1 tree!

9 Figures show that an average office worker can use about 100 sheets of paper per day and throw away about kg of paper every year.

10 In 2005, paper and paper cardboard consumption in Singapore is 144kg / person / year, that is approximately 576,440,000 kg of paper, equivalent to chopping down approximately 14 millions of trees*! * This calculation is done based on the figure given by Conservatree: 1 ton of uncoated virgin (non-recycled) printing and office paper uses 24 trees

11 Although Singapore is just a tiny dot on the world map, the level of resource consumption is of the opposite. In fact, Singapore is one of the top 25 largest paper and paper cardboard consumers in the world.

12 So, lets start reducing, reusing & recycling paper NOW! Want some tips? Provide recycling boxers besides printers, copiers to facilitate collection of waste paper.

13 Correspond electronically and refrain from printing s. Locate one tray on the copier for paper with one side used only. Choose a printer which has a duplex function. Ensure that office equipment can handle paper with a minimum of 20% recycled material and paper with only one side used.

14 Reuse old cardboard boxes for loose files, magazines or other materials, or as scrap-paper trays Reuse paper with one side used only for writing telephone message, drafting and etc and recycle them thereafter. Reuse paper bags, envelop & mailers.

15 Choose paper which has been manufactured in an environmentally friendly manner, i.e. 100% chlorine free bleaching process. Subscribe to electronic mailing list whenever possible. Proof-read documents before printing to minimize wastage of paper.

16 Do you know? A survey by the Department of Environment, in New South Wales, in 2002 showed that an office worker threw away $23 worth of reusable office stationery every year.

17 We pay little attention to the office stationery that we use daily. The combined office waste generated by these materials however is not insignificant. There are a wide range of brands and products one can choose from and with just a little bit of care, we could do our part in minimizing unnecessary waste and thus elongating the life of our Pulau Semakau Landfill.

18 Consider using Green-Labeled recycled notepads and stationery paper, Green-Labeled correction fluid and tape, refillable pens and highlighters and mechanical pencils.

19 Post Its cannot be recycled due to the glue on them. Try to replace them with scrap paper pads so that it can be recycled. If notebooks and pads are used for rough working and the likes only, try to replace it with used paper. If not, purchase those with a high recycled content. Try to use refillable pens to minimize waste. If you are purchasing disposable pens, ask for those made from biodegradable plastic.

20 Reuse! Buy those with recycled content! Purchase water-soluble adhesives which are more environmentally friendly.

21 Try to use envelop without plastic windows as they are harder to recycle or use envelopes with a high recycled content. Buy rewritable CD so that it can be reused. Purchase water-soluble adhesives which are more environmentally friendly.

22 Do you know? Backgrounds in white and bright colors can use up to 20% more power than black or dark colors. Unfortunately, and word processors tend to use white backgrounds, so your workstation uses considerable power while you are in these programs. You can change your background by selecting Start, Settings, Control Panel, Display and Appearance tab. The item "field should say Desktop. Under color, select one of the colors at the right that has a rating below 65W and then click OK.

23 Computers use about the same amount of power when they are idling as when they are being used actively. Desktop Computer watts On Screen Saver watts Laptop15-45 watts Sleep / Standby 1-6 watts Table 1. Power Consumption of a personal computer* * Based on Dell Computers

24 Energy management puts your computer and/or monitor into a low-power sleep when they are not used after a certain period of time. Consider buying a laptop since it is both energy- and material- efficient. Look out for energy-saving labels, such as Green Label and Energy Star. Refer to their respective websites for a list of endorsed products.Green LabelEnergy Star

25 Consider LCD monitor which consumes half of the energy as compared to CRT monitor. Typical 17 CRT-monitor 80 watts Typical 17 LCD-monitor 35 watts Sleeping0-15 watts Turned off at switch 0 watt Table 2. Power Consumption of a Monitor* * Based on Dell Computers

26 Energy Saving Tips Enable your power management program. Window XP Go to Control Panel Power Options Power Scheme Recommended Settings: Turn off monitor: after mins Turn off hard disk: after 2-3 hours System Standby: after mins System Hibernate: after 2 hours Window Vista Go to Control Panel System & Maintenance Power Options Power Saver

27 Energy Saving Tips Macintosh OSX Go to Apple Menu System Preferences Energy Saver Recommended Settings: Put computer to sleep after minutes Put display to sleep after 10 minutes Need more explanation? Click herehere

28 Energy Saving Tips Switch off your monitor whenever it is not in use. Switch off your computer and monitor after work. If possible, switch off the main switch as without doing so, there will be power loss ranging from watts. Turn off your screen saver Go to desktop, right click and choose Properties Screen Saver choose None

29 Do you know? Copiers are the largest energy guzzlers in the office environment, with power consumption up to 3500 kW. There is a great potential to save energy in this area because 70% of the energy consumed by copiers is used to keep it warm when idle. Even in standby mode, a photocopier is capable of consuming enough energy in one night to print over 1500 copiers of A4 paper.

30 The most effective way to save energy and reduce copying costs is to copy on both sides of the paper (duplex). Choose a copier with duplexing function. Look for a copier with an energy save button in addition to programmable power management features so that users can put the machine into low power mode as soon as they finish copying. Purchasing Tips

31 Select a photocopier with a high recycled material content and that makes use of recycled components. Choose a copier that allows you to program it to turn off when it isnt needed at the end of each work day and on weekends. Purchasing Tips Choose a copier which is either labeled with Green Label or ENERGY STAR.

33 Paper (including toner) is the biggest cost of a photocopier and has the most environmental impact. So reduce paper usage as much as possible. Give clear instructions on how to perform single-sided and double-sided copying Always use duplexing function wherever possible Choose a bin to put paper with one-side used only Do not photocopy unnecessary documents Reduce documents from A3 to A4 size if possible

34 Copiers with energy saving label. Auto-off it after one hour of inaction. Copier with the right size Recycled paper Activate Energy Saver! Recycle toners / cartridges

35 Purchasing Tips Purchase printers labeled with Green Label or ENERGY STAR Ensure the printer has toner- or ink-saving modes such as draft Choose a printer that can print double- sided and allow printing on paper that is already printed on one side. For small-volume printers that dont have the ability to print double-sided, make sure odd and even pages can be printed easily.

36 Remember, saving energy prevents pollution! Imaging products qualified under the new ENERGY STAR specification will save more than $3 billion over the next five years and avoid greenhouse gas emissions equivalent to 4 million cars. Check out ENERGY STAR qualified products here:

38 Preview to avoid wastage of paper Reuse paper with one-side used only Double - sided printing! Use a copier to make more copies Use compatible inks / cartridges & recycle them Activate Energy- Saver!

39 Do you know? Air-conditioning units are another huge energy guzzler in the office. Apparently air-conditioning accounts for about 60% of our overall energy consumption in NUS.

40 Choose properly-sized air-conditioners. How to? Click herehere Switch off all air-conditioners after office hours. Set the thermostat at 25oC. Consider buying a small fan if it is too hot for you. Purchase energy-efficient air-conditioners. Click herehere

41 Do you know? While installing energy efficient lighting systems is an important aspect of a green building, occupants can contribute to a great deal of energy savings.

42 Compact Fluorescent Lights (CFL) Light Emitting Diodes (LED) Replace conventional light bulbs or tubes with the energy efficient light ones.

43 Install occupancy sensors! Adjust the brightness in the office to save energy. Report defective sensors! Switch off lights whenever the room is not occupied.

44 In most offices, scanners are used infrequently. Switch it on only when you need to use. Nowadays, many scanners come in the form of All-in-one devices. Follow the energy-saving tips with copiers or printers. Purchase energy efficient scanners such as those ENERGY STAR qualified products. Click herehere

45 Ensure the fax machine has toner or ink-saving modes such as draft. Fill the paper bin/cartridge with paper that is already printed on one side Recycle and refill toner and ink cartridges. Fax machines are mostly inactive so it is important to choose one with a low standby energy rating. Use ink and toner saving settings


47 Purchase tissue with more than 30% of recycled content Use dryer instead of paper tower Choose recycled chlorine-free tissue products

48 Use reusable plates, glasses and cutlery Use bio-degradable disposables such as starch plates Bring your own container for take away meals if possible Remember to recycle all recyclables Use environmentally friendly dish washer

49 Do you know? Replacing a refrigerator bought in 1990 with a new ENERGY STAR qualified model would save enough energy to light the average household for nearly four months.

50 Choose an energy efficient refrigerator. ENERGY STAR compact refrigerators and freezers use 40% less energy than the conventional models sold in Choose a refrigerator with right capacity.

51 Position your refrigerator away from a heat source such as an oven, a dishwasher, or direct sunlight from a window. To allow air to circulate around the condenser coils, leave a space between the wall or cabinets and the refrigerator or freezer and keep the coils clean. Make sure the door seals are airtight. Keep your refrigerator around 3 degrees Celsius and your freezer at -18 degrees Celsius. Minimize the amount of time the refrigerator door is open. Recycle older or second refrigerators.
