Energy Efficient by Design

• All domestic appliances now have Energy labels.
• Categorising the energy performance.
• Significant energy reduction can be achieved by
  utilising the labels.

Energy Use

• Heating
• Hot Water
• Cooling
• Ventilation
• Lighting
• Electrical Loads

46
Controls

• Time, temperature, zone controls
• Building management systems (BMS). These might
  typically allow for
• Temperature control
• Timers
• Zone control
• Heating optimization
• Weather compensation
• Lighting timed control

Heating Control
52
Watch those temperatures!

• Overheating by 1C can increase fuel bills by 8
  to 10
• Overcooling by even more so

53
Insulate

• Insulation helps to prevent heat loss
• A typical poorly insulated domestic sized
  cylinder will take around 20kWh a day to service
  its losses

54
Insulation

• Most effective on hot water or steam systems
• Dont let it be removed!

Air conditioning

• Removes heat from room
• Dumps it outside
• So avoid this for example

61
Obscured temperature sensor

• Air infiltration or exchange with non-conditioned
  spaces.
• Obstructed sensor

62
Lighting

• How much light do we need?
• Depends on task
• Large energy saving potential
• Corridors often lit to 500 lux
