How can your business become more energy efficient?
Energy costs continue to rise whilst resources are diminishing. It is therefore essential for companies to understand that controlling their energy consumption will be a key part of a sustainable future.
Energy efficiency plays an important role from both an ethical and economic perspective. With the overall cost of energy rising, economic uncertainties and environmental pressures, we encourage businesses to reduce essential spend, improve efficiencies and comply with the latest energy legislations.
The Energy Savings Opportunity Scheme (ESOS) has highlighted a need to make UK businesses more sustainable by identifying and reducing carbon-based fuel usage across buildings, processes and transport.
The greatest return in energy management comes from the monitoring and targeting that effective usage information offers. This will enable you to make the required changes to gain efficiencies in specific areas of your business and ensure that any investment is fully justified.
Where do energy efficiencies come from?
There are many areas of a business that can be monitored for opportunities to improve energy efficiency. Those that will achieve the best results are the high return areas, whether whole building systems such as heating, or those specific to manufacturing plants such as machining tools or compressed air.
Here are a few common areas that can offer the greatest opportunities for improvement:
- Lighting: utilising effective controls and dimming; light harvesting can be achieved through the use of simple sensors and can provide around 60% cost savings
- Heating/ cooling: increasing the sensitivity of your controls, zoning different areas of the building and increasing the number of deadband* will avoid cooling and heating operating together; educating staff will help to maximise returns
- Motors: appropriate controllers in motors that respond to varying loads can reduce energy demands by up to 50% and prolong servicing periods and lifespan
- Power quality: evaluate the quality of power on site – poor quality will cause power losses, equipment failure and its associated costs and downtime
- Building controls: combining the controls, sensors and management information and passing control to those who fully understand the business needs allows companies to become more agile and proactive in managing their energy efficiency
*Once you are able to fully understand your business energy usage on a granular level through an effective metering and measuring strategy, the target areas for improving efficiency will form the foundation of your overall energy strategy.
* A temperature deadband is created when an installation is simultaneously heated and cooled. The low end of the deadband is just above the temperature where the heating system turns on. The high end of the deadband is just below the temperature where the air-conditioning system starts.
