Non-green offices and green offices alike share the same water mains, electric lines, phone cables, and roads – living off the grid is no alternative for most businesses, that’s for sure!

But the line between green offices and their wasteful counterparts is a thin one – and it has to do with how much energy your office expends in any given day, and how much your office has done to conserve the energy it uses, or to minimize its use.

According to the US Department of Energy, total energy consumption in an average office breaks down by the numbers:

Thermostat/Air conditioner, 39% of energy consumption. Keeping cool (or warm) is a positive energy monster – but you can’t freeze your employees to death, can you? Green offices do their part for their employees and the environment by changing roof coatings and insulation to protect against heat and cold, or by setting the thermostat a little closer to outside ambient temperatures – to a cooler setting in winter, or a warmer setting in summer.

Lighting, 30% of energy consumption. By opening the office windows to let natural light in, or by switching light bulbs to the compact fluorescent type, offices can save up to eighty percent of the lighting energy they use.

Office equipment, 16% of energy consumption. Real green offices make sure that office equipment use is conserved and minimized. This includes switching idle computers off and converting monitors to power-friendly LCD or LED monitors.

Water heating, 9% of energy consumption. Like thermostats, water heating can be conserved, too – reducing water temperature to 120 degrees, for example, saves up to 18% of total energy use. Low-flush toilets can help reduce energy consumption even more, as they save up to 50% over more old-fashioned commodes.
