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

4

Why not?

• Investment costs

• Hidden costs

• Transaction costs

• Market failures

• Ignorance, Inertia, Internal structures

The national context

5

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.

6

Local Examples: Minchinhampton Golf Club

Key Points

• 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.

Energy use

How can we check it is being used effectively?

Understand current use

2. Walk round: Look at

Hot water

Lighting

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

12

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
