- Use low Energy light Bulbs
Use energy efficient light bulbs (CFLs). Not only do they last up to 15 times longer than ordinary bulbs, CFLs use 80% less electricity. Remember turn off lights when they are not required. - Increase insulation in walls, attic & floors
- Install attic insulation and / or top up existing insulation
- Ensure you have lagging jacket on your cylinder,
- Cavity Wall insulation
If your home has been built with a cavity but has no insulation there are three methods of increasing your thermal rating:- Pump in proprietary insulation material through holes in the outer leaf of the wall.
- Install insulated plasterboard on internal walls.
- Install insulation and rendering to outer walls
- Energy Efficient Windows & Doors
Review the type of windows you have. If you have single pane glass windows consider replacing them with double glazed or triple glazing windows both with low emissivity glazing. Double glazing would reduce heat loss through the windows by 1/3rd and low emissivity triple glazing would reduce heat loss by over 2/3rds. - Controlled Ventilation System
Whilst ventilation is necessary, excessive ventilation can result in energy wastage. Controlled vents should be installed in every room. Cooker hoods and small extract fans should be installed to allow for controlled removal of moist air from kitchens and bathrooms. Draught proofing may be applied to doors and windows. - Heating Systems
A 93% efficient boiler will save about €600 a year in fuel. If you have a boiler with an efficiency of 80% or under it is worth considering replacing it with one of the modern condensing boilers which have efficiencies of up to 97%. This will improve the BER considerably. - Modern Heating Controls
Improving the heating control system can reduce the BER quite significantly. There are a variety of possibilities depending on the type of heating system present, e.g. for boiler systems the ideal is to have time & temperature control.
