Replace Dated Equipment
Whether it's the toaster in the common room or entire HVAC system, it can really pay to upgrade your fixtures to energy efficient models, especially if your office is in an old building. Energy Star is a rating system that was devised to assess the efficiency of products. Check all of your components to make sure they make the grade. If they don't, a single investment could significantly reduce your monthly energy bills – you will soon recoup your costs.
Turn Off the Lights
Maximise as much natural sunlight as possible, rather than using electricity. Remove any obstructions from in front of the windows, or perhaps rethink the layout of your office entirely. Placing desks in well-lit areas will not only limit the need for desk lamps and overhead lighting, but will make your employees feel more awake. In addition, encourage your workers to always turn off the lights in areas that aren't used as frequently, such as the bathroom and kitchen (or consider investing in automatic lighting).
Implement a “Standby Plan”
In the everyday office, computers are constantly kept on standby. While switching off a monitor will reduce energy consumption a little, the computer itself is what really drains the grid. Start encouraging employees to turn off their computers when they're not using them, and unplug “vampire electronics” when they're fully charged: mobile phones, laptops, tablets.
Modify the Temperature
A decent HVAC system can cut down your energy consumption by up to 40 percent, so make sure it's tuned up on a regular basis and free from leaks – the harder it has to work, the more energy it will waste. If you have a programmable thermostat, adjust it frequently to prevent over-heating/cooling.
Go Paperless Wherever Possible
Even in today's largely digital office spaces, paper is one of the biggest contributors to waste. Yet with the Cloud and other web-based storage systems, there's really little need for paper at all. Getting rid of the filing cabinets and keeping everything digital could not only reduce your office's carbon footprint, but could save a phenomenal amount of space – this may even reduce your rental bills.
Actively encourage everybody in your office to make positive changes. Perhaps you could even offer an incentive, such as bonus payments for the money that you have saved. And finally, if you're concerned about your energy consumption, consider getting an energy audit. A professional auditor will be able to assess your office and tell you exactly what changes need to be made. Over time this could lead to substantial savings.
