Increase your home efficiency, reduce your carbon footprint and save money

The first step towards reducing our energy and water consumption is to increase our knowledge and awareness.

And there is not better way to increase our awareness than calculating how much water and electricity we are using. For that, we have made available several calculators for energy and water calculations.

Before going ahead, we really recommend to first have a look to the Effiworkx YouTube channel videos. On those videos we explain concepts that will be of your interest.

How to reduce your shower water consumption by installing a flow reduction valve

How to measure your appliances and devices power consumption using a plug-in power meter

What is a Kilowatt Hour (kWh)? - Acquire the knowledge, use it and save money

How to install a water saving tap aerator - Reduce your faucet water consumption and save money

Learn how to read a water meter and how much a cubic meter of water is

Learn what standby power is, how to prevent standby power waste and save money

This calculator can be used to:

– **Calculate an appliance power consumption**. E.g. kettle, microwave oven, toaster…

– **Calculate an appliance power consumption while in standby mode**. E.g. desktop printer, computer monitor, charger,…

Note that an appliance power consumption in standby mode it is most probably much lower than during normal operation. Therefore, in order to calculate the standby mode power consumption of an appliance over time, it is necessary to **find out the instantaneous power consumption while in standby mode**.

This calculator can be used to:

– **Calculate the total cost to run a dishwasher cycle**, including water and electricity consumption.

A dishwasher has many different cycles and options to chose from (e.g 70°, 45°, Auto, Rinse, Vario Speed…) and each cycle will have a different electricity and water consumption.

The most effective way to calculate a specific cycle electricity consumption is to use a **plug in power meter**.

For calculating a cycle water power consumption, the dishwasher manufacturer datasheet can give an indication or we can **check the water meter reading** before and after the cycle.

This calculator can be used to:

– **Calculate the total cost to run a washing machine cycle**, including water and electricity consumption.

A washing machine has many different cycles and options to chose from (e.g. Regular, Cotton, Delicate,…) and each cycle will have a different electricity and water consumption.

The most effective way to calculate a specific cycle electricity consumption is to use a **plug in power meter**.

For calculating a cycle water power consumption, the washing machine manufacturer datasheet can give an indication or we can **check the water meter reading** before and after the cycle.

This calculator can be used to:

– **Calculate the cost to run a tumble dryer cycle.**

A tumble dryer has many different cycles and options to chose from (e.g. Regular, Cotton, Delicate,…) and each cycle will have a different electricity consumption.

The most effective way to calculate a specific cycle electricity consumption is to use a **plug in power meter**.

Buying the most energy efficient appliance is going to save electricity and reduce the electricity bill over time but, if the initial investment it is large, it may take many years to reach the break even point.

As an example, if the average life expectancy of a fridge it is 15 years, is it really worth to purchase a more efficient but also more expensive fridge or would make more sense to buy a less efficient but also less expensive fridge?

Fridge efficieny class | A+++ | A++ |
---|---|---|

Power consumption per year | 174 KWh/year | 252 KWh/year |

Fridge cost | 1159 | 899 |

Electricity cost per year at 0,17 euro per kWh | 29,58 | 42,84 |

Electricity cost over 20 years | 591,6 | 856,8 |

Total cost over 20 years (fridge+ electricity) | 1750,6 | 1755,8 |

This calculator can be used to:

**– Calculate the electricity costs over time and the break even point.**
