Questions for Today
•How much energy is used in in a small business?
•Where is energy used?
•Why reduce energy use?
•Local Examples
•How can we check it is being used effectively?
•How can we reduce ineffective use?
•Will we have to spend to save?
•Is there any assistance available?
Energy in SMEs
• How much energy is
used in a small
business?
• 10 years ago, average 4% of costs
• Last year, average 10% of costs
3
Energy use
•Where is energy used?
Heating and Hot water
Lighting
Cooling
Equipment
Motivation
Why might we want to reduce energy use?
Cost
Comfort
Environment
Image/client pressure

Why not?
• Investment costs
• Hidden costs
• Transaction costs
• Market failures
• Ignorance, Inertia, Internal structures
The national context

Local Examples: U Godsell and Sons Dairy Farm
Key Points
• Simple no and low cost steps
already taken
• Modern variable speed milking
pump cuts annual milking pump
energy use by £1000 pa
• Compressor heat recovery will cut annual hot water heating costs by
£100 pa
Local Examples: The Retreat Bar
Total gas and electricity use
and bill reduced by 15%.
Cellar service running costs cut by new cellar insulation:
Cooling costs halved.
Installation of timers on lights ensures they are only on when
they should be.
Smart meter enables savings and problems to be identified in real time.

• First stage of new efficient
lighting in new course clubhouse reduces annual electricity bills by £1,500 p.a.
• Improved heating in Old Course Clubhouse improves
comfort and cuts annual gas bills by £500
• Air blade hand dryers reduce costs by £5,000 per year.

2. Walk round: Look at
Heating
Hot water
Lighting
Building fabric
Equipment

Four categories of energy waste
INAPPROPRIATE• Use of inappropriate fuels e.g. on peak electricity as heating fuel
INEFFICIENT
• Poorly maintained boilers• Use of traditional bulbs instead of energy saving lamps
POORLY CONTROLLED
• Timer and/or temperature controls wrongly set
• Relying on manual control
UNNECESSARY• Equipment and lights that are redundant
Where do the opportunities lie?
• No Cost
• Low Cost
• Capital Cost

Energy Efficient = High Cost?
Management vs. technical solutions

Lighting
� Is daylight enough?
� Lighting controls: manual, timed or presence sensors?
� Who’s responsible for switching off?
� Which switch is it anyway??
� Are light fittings clean?
� Are light bulbs efficient?
Energy survey
Building fabric
13
Energy survey
Equipment
Equipment
� Are computers and equipment left on when not being used?
� Are “power save” modes used?
� Is energy consumption considered when purchasing?
� Does equipment reduce the need for heat or increase the need for cooling?
14
Main Survey Recommendations
• Heating issues – temperature, time settings & control
• Heating/Cooling clash
• Time switches on electrical equipment (water heaters)
• Lighting – management and type
• Secondary/Double glazing
• Heating control (TRV)
• Office equipment
• Staff awareness – work and home
Energy walk around – when?
� Lunchtimes
� Shift change
� At night / over the weekend
� When the cleaners are on duty
� Beginning and end of the heating season
� When the clocks change
