Usage Profile
Knowing your Usage Profile will help you to understand when and where you are using energy in your household or business, enabling you to consider behavioural change eg. considering using the washing-machine at a different time of day..
You can build that understanding of your energy use by keeping track, either simply by checking your electricity bills to see how many units you've consumed or by different types of monitoring which will give you data on your usage as you use it.
Monitoring is possible at different levels, from a small device connected to the meter-feed to measure total usage or by , as would happen in a larger business, connecting a device, a meter, to each appliance
Voltage Optimisation
Voltage coming into the premises can vary in a range of from 240V down to 215V so to get best and most cost-effective performance from your appliances, the voltage should be optimised to run at a steady 220V. Industry uses voltage optimisation for iits machines, and voltage optimisation units are now available as small domestic units easily installed in a home or small business
When analysing the effects of supply voltage variation on power consumption and ultimately cost to the consumer it is found that domestic appliances can be divided into 3 general types i.e. Resistive, Inductive and Electronic
Resistive devices have a prime function to produce light and heat and make up 60% to 80% of most household energy usage
The inductive devices are often those with some form of electric motor whose output is that of mechanical work albeit that work may be used to provide heating or cooling as in the case of refrigerators and air conditioners. These devices contribute between 10% to 40% of household energy use
The electronic devices form part of entertainment systems in the home but are becoming more common in all appliances where some form of control is required. These are normally low power devices and rarely contribute more than 20% to the energy cost
Efficient Appliances
Developments in design of domestic appliances means that, for example, the latest energy efficient refrigerators, for example, use 40 percent less energy than conventional models did in 2001
Following this, if all households in Europe changed their more than ten year old appliances into new ones, 20 billion kWh of electricity would be saved annually, hence reducing CO2 emissions by almost 18 billion kg
According to a 2009 study from McKinsey & Company the replacement of old appliances is one of the most efficient global measures to reduce emissions of greenhouse gases
Standby
Modern power management systems also reduce energy usage by idle appliances by turning them off or putting them into a low-energy mode after a certain time
Monitoring
Monitoring and establishing your energy Usage Profile will help you to understand how much and when you are consuming electricity and other forms of energy, such as gas
Our enData service is simple to use:
Data for setting up your Usage-Profile is obtained by monitoring your supply coming into your home, or other type of building
Once you have the data, usually presented in chart form making it easy to see at a glance when you're going "over the line", you can decide if you need to make adjustments to the way, and to when, you're using electricity, and/or gas
The charts can be viewed on your computer screen both off-line and online through a connection throuhgh the Internet
Data can also be presented in analsysis sheets to print off and study or to view on screen
Example: the charts show a household's temperature movements and electricity use in a month
