The following energy tips are better suited for small offices, although some tips are also applicable for bigger firms. Big offices should check with a professional energy consultant.
Use energy efficient bulbs for your lighting.
Use task lighting to directly illuminate work areas.
Keep doors to colder rooms (e.g. stockrooms) closed.
Consider organizing a video conference instead of travelling each time to a meeting. This saves time, money and you help reduce CO2-emissions.
Don't use air-conditioning if outside temperature is not above 25°C.
Keep air-conditioning thermostats at 24 /78 degrees or higher during summer months.
Clean or replace filters regularly to help air-conditioners run more efficiently.
If you have a carpool, buy fuel-efficient cars and mind your CO2-emission.
Encourage your workers to share rides to and from work (car sharing).
Move your working desk closer to the window. This way you can profit more from the sunlight and you can keep artificial lights turned off for a longer time.
Only make photocopies when really needed and turn off the copy machine after every use. Keeping appliances in stand-by mode wastes great amounts of energy over time. Another option is to use a device which keeps the machine running but prevents electricity consumption like in the normal stand-by mode (see products: Ecoman).
Regulate the room temperature of your office wisely. Turn down the heating at night. Open the window and aerate the room intensively but for just a short time. Keeping the window constantly open, by tilting the window frame for example, wastes a lot of energy. You can even install a programmable thermostat.
Install time clocks or photoelectric cells to control exterior lighting, advertising sign lighting and some interior lighting.
Turn off PCs, monitors, printers, and copiers at night and on weekends. If you are unable to switch off the entire computer, turn off the monitor and printer and any other external hardware.
Connect PCs, monitors, fax machines and computer peripherals to one power strip. Turn off that power strip every night and when not in use.
Use laptop computers and ink jet printers, if available. They use 90% less energy than desktop and laser printers.
Collect ink cartridges from your copying machines and printers and refill them, instead of buying new ones. This saves you money and is more ecological.
Implement paper-reducing strategies, such as double-sided printing, re-using paper, and using e-mail instead of sending memos or faxing documents. This does not only save energy but also conserves other resources.
Purchase energy-saving PCs, monitors, printers, fax machines and copiers (look for Energy Star models).
Provide a collector for PET-bottles in your office.
Use recycled paper.
Install water-saving toilets and faucets.
Check with your utility company for energy conservation tips.
No matter your profession, be aware and open to sustainable options and projects!
