As a human race we would probably find things rather difficult without the Earth, so it makes good sense to try to make it last. Reduce our dependence on the fossil fuels that are becoming increasingly limited in supply.

Controlling and reducing energy consumption at your organization Energy management is the means to controlling and reducing your organization's energy consumption And controlling and reducing your organization's energy consumption is important because it enables you to: Reduce costs — this is becoming increasingly important as energy costs rise. Reduce carbon emissions and the environmental damage that they cause - as well as the cost-related implications of carbon taxes and the like, your organization may be keen to reduce its carbon footprint to promote a green, sustainable image.
Not least because promoting such an image is often good for the bottom line. With energy management you can reduce this risk by reducing your demand for energy and by controlling it so as to make it more predictable.
On top of these reasons, it's quite likely that you have some rather aggressive energy-consumption-reduction targets that you're supposed to be meeting at some worrying point in the near future Your understanding of effective energy management will hopefully be the secret weapon that will enable you to meet those aggressive targets How best to manage your energy consumption?
We identified four steps to the energy-management process above.
We'll cover each of them in turn: 1. Metering your energy consumption and collecting the data As a rule of thumb: the more data you can get, and the more detailed it is, the better.
The old school approach to energy-data collection is to manually read meters once a week or once a month. This is quite a chore, and weekly or monthly data isn't nearly as good the data that comes easily and automatically from the modern approach The modern approach to energy-data collection is to fit interval-metering systems that automatically measure and record energy consumption at short, regular intervals such as every minutes or half hour.
There's more about this on our page about interval data.
Videos and Brochures
Detailed interval energy consumption data makes it possible to see patterns of energy waste that it would be impossible to see otherwise. For example, there's simply no way that weekly or monthly meter readings can show you how much energy you're using at different times of the day, or on different days of the week. And seeing these patterns makes it much easier to find the routine waste in your building. Finding and quantifying opportunities to save energy The detailed meter data that you are collecting will be invaluable for helping you to find and quantify energy-saving opportunities.
We've written an article that explains more about how to analyze your meter data to find energy waste. The easiest and most cost-effective energy-saving opportunities typically require little or no capital investment. For example, an unbelievable number of buildings have advanced control systems that could, and should, be controlling HVAC well, but, unbeknown to the facilities-management staff, are faulty or misconfigured, and consequently committing such sins as heating or cooling an empty building every night and every weekend.
It's a term that's more widely used in some countries than others. And one of the simplest ways to save a significant amount of energy is to encourage staff to switch equipment off at the end of each working day. Looking at detailed interval energy data is the ideal way to find routine energy waste. You can check whether staff and timers are switching things off without having to patrol the building day and night, and, with a little detective work, you can usually figure out who or what is causing the energy wastage that you will inevitably find.

Our article on energy-performance tracking explains how best to analyze your metered energy data to see how well you're making progress at saving energy. Like step 2, this step is one that our Energy Lens software has been specifically designed to help with.
At the very least you should keep analyzing your energy data regularly to check that things aren't getting worse. It's pretty normal for unwatched buildings to become less efficient with time: So at a minimum you should take a quick look at your energy data once a week, or even just once a month, to ensure that nothing has gone horribly wrong It's a real shame when easy-to-fix faults such as misconfigured timers remain unnoticed for months on end, leaving a huge energy bill that could have easily been avoided.
But ideally your energy-management drive will be an ongoing effort to find new opportunities to target step 2 , to target them step 3 , and to track your progress at making ongoing energy savings step 4.

Software Articles Videos Support. The What, Why, and How of Energy Management This article explains what "energy management" is, why it's important, and how you can use it to save energy. We'll start with the "what" , and then move on to the "why" , and the "how": What is energy management?
The energy-saving meaning When it comes to energy saving, energy management is the process of monitoring, controlling, and conserving energy in a building or organization. Typically this involves the following steps: Metering your energy consumption and collecting the data.
Finding opportunities to save energy, and estimating how much energy each opportunity could save.

You would typically analyze your meter data to find and quantify routine energy waste, and you might also investigate the energy savings that you could make by replacing equipment e. Taking action to target the opportunities to save energy i. Typically you'd start with the best opportunities first.
Tracking your progress by analyzing your meter data to see how well your energy-saving efforts have worked.

Also, most buildings have open to them a variety of equipment- or building-fabric-related energy-saving opportunities, most of which require a more significant capital investment.
How best to manage your energy consumption? Most homeowners aren't even aware of the term, and take more of a haphazard, flying-blind approach to reducing their energy consumption Although your detailed meter data won't necessarily help you to find these equipment- or building-fabric-related opportunites e. The old school approach to energy-data collection is to manually read meters once a week or once a month.

Tracking your progress at saving energy Once you've taken action to save energy, it's important that you find out how effective your actions have been: Energy savings that come from behavioural changes e. Your understanding of effective energy management will hopefully be the secret weapon that will enable you to meet those aggressive targets
