Objective:

The purpose of this Cost Benefit Analysis (CBA) is to assist you in identifying the cost savings when using our Energy Saving Systems. Please remember that this CBA is an illustrative example of savings that could be achieved and not a guarantee. The main list of values is stated in USD (United States Dollars) however, we have also placed the value of the USD in UK Pounds, Euros and Chinese Renminbi (RMB). If your currency value is not USD, just change the USD amount until you see the correct value in your currency appear on the right side of the CBA.

How to Complete the Cost Benefit Analysis: 

To find out what your cost savings are likely to be, you must know certain facts:

a) The "True" value of your incoming main voltage;

b) The power rating of your appliances in Watts and Kilowatts;

c) The cost of a 'unit' of electricity (Kilowatt per hour) charged by your electricity supplier and the average monthly use of electricity in Kilowatts;

d) The replacement value of your appliances in your home or office.

These are explained in more detail below. If you do not need further details, please select the energy saving system at the bottom of this page to start your Cost Benefit Analysis.

Further Details:

1. The TRUE value of your incoming mains voltage into the property. Asking your power supplier to give you this information will NOT give you the TRUE value. As an example, in the UK the power companies will quote you a 'nominal' value of 230 main Volts; however the TRUE incoming voltage will be 240 to 252 Volts, with an average of 246. This is also true of many other power suppliers all over the world. They aim for a main voltage, but due to other users, transmission losses and weather conditions, the voltage arrives at your home/office at a very different value. Remember, that 90% of the appliances and lighting systems in +200 volt countries operate more efficiently at 220V. Over and/or under voltage creates higher electricity bills and shorter life for your appliances; and of course creates more CO2 emissions than are needed. Please use the Internet to check your regional incoming property voltage. Use this TRUE voltage value in the CBA. You can also purchase an inexpensive device (about 15 USD) that plugs into most mains sockets and tells you the TRUE value of your incoming main voltage.

2. The power rating of you appliances in your home/office. The power rating of your appliances is usually measured in Watts or Kilowatts (thousand of Watts). The only way to accurately find out the power rating of the appliance is to look on the manufacturers plate usually located on the rear of the appliance.

3. The cost of each unit of electricity and the monthly amount of Kilowatt Hour (1,000 watts of electricity used for 1 hour) usage in your property. This information will be shown on any bills or invoices you have received from your power supplier. Remember to take an average (the annual total KW/H and/or cost, divided by 12 months – if you have a monthly bill/invoice) of all your bills/invoices to find the AVERAGE monthly kilowatt usage; and use this average figure in the CBA.

4. The replacement value of all the electrical appliances in your home so as to identify the value of the increased life cycle of your appliances. To help you identify this total value, you need to list all your appliances and then give them a replacement value.

There are a number of pages on this website that provide power usage and other helpful facts to assist you in calculating some of the items above.
