This document provides practical tips for businesses to improve sustainability through energy and carbon management. It defines sustainability and discusses key drivers like climate change and government policy. It then outlines various energy reduction opportunities for lighting, offices, refrigeration, compressed air, heating, and insulation. Specific tips include installing lighting controls, raising refrigeration temperatures, improving boiler maintenance, reducing unnecessary heating/cooling, and improving insulation. The overall message is that businesses can cut energy use and costs through low-cost behavior changes and maintenance improvements.
8. Drivers for Energy & Carbon Management Environmental Issues Climate Change and emissions pollute from almost everything we do Government Policy Reducing CO2 emissions by 80% by 2050 Strong role for energy efficiency and renewable energy Systems Costs & Reputation Benefits associated with promoting energy efficiency
16. Climate Change – What’s Happening? 0.6°C Average global temperature rise since records began in the 19th Century All 10 of the hottest years have occurred since 1900
23. Practical Introduction to Energy Awareness Creating an energy awareness programme depends on your own particular circumstances. Some sites are more advanced than others, while some individuals are less energy aware than their colleagues. There are four essential steps:
27. A Practical Introduction to Reducing Energy - Lighting Lighting is essential for carrying out daily business activity but it can account for up to 40% of a company’s total electricity bill. Automatic lighting controls can save 30% on costs. Lighting costs can be reduced by 20% by only using electric lighting when the space is occupied
28. A Practical Introduction to Reducing Energy - Lighting Use the sun. Encourage staff to keep lights off where there is sufficient daylight. Clean windows and skylights regularly. If you can, angle blinds to reflect more light onto the ceiling or into the workspace.
30. General Energy Saving Opportunities - Office Every office needs a range of equipment in order to function and be productive, but did you know that you could cut your office energy use by over 70% at little or no cost?
31. General Energy Saving Opportunities - Office PCs/Monitors use almost half the energy of all office equipment Switch off PC monitors and other equipment if they will not be used for 15 minutes or more day
33. A Practical Introduction to Reducing Energy - Refrigeration A chiller door left open for 30 minutes a day wastes enough energy in a year to power a lighthouse for nearly 4 days. An open chill door will cost you at least £2 an hour and a deep-freeze £6 an hour.
34. A Practical Introduction to Reducing Energy - Refrigeration You don’t have to refrigerate many products below the recommended temperatures: increasing the temperature of the cooled space by just 1ºC could reduce energy consumption by 2%. Keep condensers clean and free from blockages so that there’s enough space for good airflow away from the unit. Repair any leaks as soon as possible and recharge the system with fresh coolant. Your refrigeration maintenance supplier will be able to do this.
36. A Practical Introduction to Reducing Energy– Compressed Air Over 10% of electricity supplied to industry is used to compress air. However, as much as 30% of this energy is lost through leaking systems Compressed air leaking through a single 3mm hole could cost you over £500 per year!
37. A Practical Introduction to Reducing Energy– Compressed Air Don’t compress air to pressures higher than is really necessary Leaving compressors running when they aren’t required, such as during breaks An idling compressor can still use 40% of its full load. Having hot, wet or ‘dirty’ air means that the compressor has to work harder.
39. A Practical Introduction to Reducing Energy– Heating Around 20% of heat generated by a boiler goes straight up the chimney. This can increase to over 30% if the boiler is poorly operated or maintained. Simple maintenance can produce significant energy savings — often as much as 10-15%
40. A Practical Introduction to Reducing Energy - Heating Good boiler maintenance is essential to ensure efficient combustion. Have your boiler serviced regularly. Make sure that your boilers are turned off when there’s no demand for heat, especially when buildings are unoccupied in the evenings and at weekends. Be sure to stop all leaks in water, heating and steam pipes.
46. A Practical Introduction to Reducing Energy - Insulation Many businesses waste a significant proportion of energy through poor insulation of their heating or steam system. An un-insulated valve is equivalent to 1 metre of un-insulated pipework. An un-insulated flange is equivalent to 1/2 a metre of un-insulated pipework. Every un-insulated metre of pipe could cost you around £100 a year
47. A Practical Introduction to Reducing Energy - Insulation Don’t underestimate the amount of heat that can be lost through poorly insulated pipework. Remember – this waste heat is probably leaking into unwanted areas. Don’t leave any gaps in your insulation Insulation should begin where the pipe leaves the boiler Replace any insulation that feels wet, it won’t prevent heat loss and will speed up pipe corrosion.

Gro Harlem Brundtland, made the definition of Sustainability when Chairwoman of the World Commission on the Environment and Development in 1983.Currentlythe new director general of the World Health Organisation (WHO).Was Norway's first woman Prime Minister. More commonly known as the Brundtland Report.
Government has a target of 80% CO2reductions by 2050 based upon 1990 levels. With aims to make a 22% reduction between 2010-2012 and 34% by 2022. Central Government office estate to be carbon neutral by 2012.Talk has already moved to cleaning up our grid electricity supply with new Nuclear reactors planned to be online by 2018.Carbon Neutral is now a big goal for some big brand names, Sainsburys has pledged to switch to CO2 cooling by 2030, with 134 stores planned for conversion by 2014. If all supermarkets switched to CO2 cooling then emissions could be reduced by 2 million tonnes per year.
Solar radiation comes into earths atmosphere and reaches the clouds and ground objects. The earths atmosphere allows the long wave radiation .Short-wave radiation from the Sun readily penetrates Earth's atmosphere to reach the ground. Longer wavelength radiation re-emitted from the ground is trapped by atmospheric constituents such as carbon dioxide, raising the planetary temperature. This "greenhouse effect" is significant in keeping Earth habitable; on Venus, however, it has led to inhospitably high temperatures. The past 150 years or so have seen a significant increase in levels of "greenhouse gasses" (such as carbon dioxide and methane) in the Earth's atmosphere. This is thought to have led to a long-term increase in global temperature. It is possible that this increase may also have something to do with variations in sunspot activity; however, it is widely accepted that the greenhouse effect is a highly significant cause of climate change. If the proportion of solar energy trapped in our atmosphere continues to rise, global temperature will do likewise, with potentially catastrophic effects.
Current climate models predict - global temperatures could warm from between 1.4 to 5.8oC over the next 100 years, depending on the amounts of greenhouse gases emitted and the sensitivity of the climate system. Rising average temperatures – the warmest years seen are all since 1990Rising sea levelsRapid rise in weather-related natural disasters (flooding, droughts, hurricanes) . . . and consequent insurance costsDecline in winter ice/snow and glacier retreatRapid decline in Arctic sea-ice thickness and loss of Antarctic Glaciers . . . and this is just the beginning of the beginning

PLANIdentify, by understanding, likely biggest users Consult your staff for guidance Consult internal / external experts Take a guess Decide how you are going to ascertain usage and over what period Consider what you hope the data will indicate Decide on another factor against which to compare the usage (benchmarking) Here are the main points to consider:Support and resourcesYour current situationYour target audience and goal settingMessages and communication channels.DORead YOUR meters! Install temporary meters / data loggers to record periodic consumption Collect data Collect other factor component Consider tool to use for analysis / comparison Spreadsheets Graphsetc.CHECKWhat does the analysis tell you Good news Bad news Needs further investigation Maintain status quo
First thing needed is support from Senior Management. Support from senior management is critical and should be visible to all staff in the organisationYou will need practical resources to begin your energy awareness programme. Where will you get them from?Who has the authority to grant them? You might want to set up an ‘Energy Team’ which includes representatives from all parts of the organisation.People you may need additional helpApproach potential candidates and ask them to commit to the programmeServices — think about whose support you will neede.g. IT, in-house reprographics, human resources, etcSystems already in place could include internal mail, intranets or standard communications from human resources.Get your colleagues to complete a short questionnaire. You may want to complete it with them in order to glean more information about current attitudes and awareness and also to ensure it is done within your time-frame. Current SituationWhere are you now? Know your company’s energy consumptionIdentify where and how most energy is wasted and by whomFind out how aware staff are about energy waste.Your Target AudienceYour staff — many different groups and individuals will all be key to the success of the programme. Don’t forget about external contractors, such as cleaners or security staff who may also use energy or control its use. All these people will influence energy use in different ways. Walk around and talk to people. Most people will be interested in doing their bit to save energy once they are shown how and why.COMMUNICATIONPeople are constantly bombarded with promotional messages.Your messages and slogans will have to be punchy and variedPeople will respond to different reasons and motivation for saving energy.It depends on their position and time they have been with the organisation. Use part of an existing notice board or create a dedicated energy display as a focal point for communicationsFocus your communications. Effective e-mail messages should be relevant and interesting.Do not annoy or bore your colleagues. Promotional materialsInclude messages on promotional materials such as diaries, calendars, Christmas cards, leaflets, brochures, mouse mats.Word of mouthWord of mouth is often the most powerful method of communication. Successful messages are those which provide information and get people talking about the issue.Staff newsletter/magazineYou could use it to publicise the energy awareness programme.Make raising energy awareness a regular featureCompetitionsCompetitions are an excellent way of getting staff to participate in saving energy.
Posters can contain different types of messages: news, questions and commands.Replace regularly.The better the quality, the more effective a poster campaign.Place posters at point-of-use and at eye-level.StickersLabel equipment with colours, e.g. red, switch off after use; green, can leave on
The picture showing ice build-up could be poor controls or a loss of refrigeration
Carry out regular checks on room thermostat settingDiscuss at team briefings and meetings (during heating season )Spot obvious error on the stat, this is using 16% more energy, see set at 21CMaximum room temperature for standard room heating is 19°CMinimum room temperature for standard room cooling is 24°C
