Savings

CO2 Emissions

1. All CO2 values quoted are based on ESB Customer Supply Fuel Mix information refers to 2007 (625g per kWh).
2. The CO2 emission figure used for the calculation of equivalent distance travelled is 155 grams of CO2 per kilometre which is the typical figure given for a 1400 cc petrol engine driven car.

Calculated Energy Cost Savings

1. Unless otherwise stated, all electrical energy cost saving calculations are based the Domestic Urban Tariff rate Oct 2009 of 16.00 cent per kilowatt hour including VAT.
2. Savings for CFLs are based on 1000 hours use per year of a low energy equivalent to a standard tungsten filament light bulb. An example is the use of a 20 watt CFL in place of a 100 watt incandescent bulb.
3. 3. Energy consumption for a large range of domestic appliances is available by using ESB Customer Supply's "Appliance Calculator" which is available by clicking on the link below. Using the calculator will also enable you to choose the usage pattern particular to your circumstances. https://www.esb.ie/esbcustomersupply/residential/energy_efficiency/appliance_calculator.jsp.
4. 4. All space heating savings assume natural gas central heating at the Standard Tariff rate quoted by Bord Gais March 2008.

Energy Saving Light Bulbs (CFLs)

Note: Standard CFL's are not dimmable and if dimming is required then you must use a special 'dimmable' version.

Comparable Lights
Use this handy table when replacing your ordinary bulb to find the nearest equivalent wattage in a CFL

Comparable Lights
Ordinary Bulb	Nearest Equivalent CFL
25 - 40 watts	7 - 9 watts
60 watts	11 - 15 watts
75 watts	15 - 20 watts
100 watts	20 - 23 watts

Kitchen Downlighter:

The choice is between Compact Fluorescent Lamps (CFLs) and halogen. CFLs are approximately three times more energy efficient than halogen. Use fluorescent where possible.

There are two types of halogen downlighter widely used - low voltage (12volt) and mains voltage (GU10) : The low voltage type are more energy efficient than the mains (GU10) type and the lamps last longer. A new type of low voltage energy efficient diachronic lamp has now become available. It has an infra red coating on the inside of the lamp which saves energy and it is known as an 'IRC'. A 35 watt , IRC, low voltage lamp will directly replace a 50 watt standard low voltage diachronic lamp giving increased light output and lamp life.

Washing Machine

The indicated saving is based on one full load wash per day.

Tumble dryer

The indicated saving is based on the use of a 5kg load vented type tumble dryer. A vented type tumble dryer is more energy efficient than a condenser type.

Fridge / Freezer

Savings assume replacing an average appliance purchased new in 1995 with an Energy Saving Recommended model of similar size.

Dishwasher

Savings assume replacing an appliance purchased new in 1995 with an Energy Efficient model of similar size.

Games Console

Energy saving based on the latest high performance games console rated at 160 Watts.

Television and Home Entertainment

Energy savings based on switching off home entertainment equipment (set top boxes, programme recorders, sound and game systems etc) rather than leaving them on standby when the attached television is not in use.

Desktop Computer

The energy saving is based on separately powered computer peripherals such as monitor, speakers, printer, scanner etc that are switched off when the computer is not is use.

Shower

Energy saving is based on using an instantaneous electric shower rated 9.5 kW for a daily 5 minute shower and up to 35 litres of water, instead of a daily bath using 80 litres of water. Cost saving is calculated using the Domestic Urban Tariff Oct 2009 at 16.00 cent / kWh including VAT

Double Glazing

The suggested saving is approximate, and provided for illustration purposes only.

Hot Water Cylinder

Saving based on heating the water for 1.5 hrs each day on the Domestic Urban Tariff Oct 2009 at 16.00 cent / kWh including VAT.

Water Heating Control

Based on saving 15 minutes of wasted heating each day for 6 months on the Domestic Urban Tariff Oct 2009 at 16.00 cent / kWh including VAT.

Attic insulation

The suggested saving is approximate, and provided for illustration purposes only. Individual savings may vary depending on a range of factors. Please refer to the current Building Regulations for more detailed information on insulation requirements.

Solar Water Heating Panels

A 3 square meter Solar Water Heating Panel can contribute up to 1500 kWh per year to domestic water heating requirements depending on its orientation and environmental conditions. Cost saving calculations are based on the use of an electrical immersion heater on the Domestic Urban Tariff Oct 2009 rate of 16.00 cent per kilowatt hour including VAT. Expert advice should be sought before considering this option.
