Energy saving ways to stay cool this summer

Summer finally seems to be on its way and if you’re serious about keeping your business energy costs down you need to start planning ahead for the warmer months.

Small energy-saving measures can make a big difference.

Check your air con

Make sure any air conditioning equipment is energy efficient. Fit timers and sensors to pumps and fans so that they are not cooling the office when no one’s there. Think about where you put air conditioning sensors – if they are by a door (and the heat from outside), that might mean the air conditioning stays on longer than necessary. When you do have it switched on, keep windows and doors closed to stop cool air escaping.

The transition from winter to summer doesn’t need to be expensive. Make sure there is a few degrees between the temperature that your heating and air conditioning operate at. For example, don’t have the heating stopping at 21°C and the air-con coming on at 22°C – try to leave a 3-4 degree gap in which people should naturally feel comfortable.

Switch off boilers

There may be equipment on in summer that you don’t need. Switch off boilers you’re not using to save on the costs of heating water.

Turn off vending machines

Yes, drinks need to be cooled when people are in the office, but not on the weekends. Turn off vending machines when they’re not in use. The same goes for refrigerators storing non-perishable goods.

Think about the lights

With bright sunshine – hopefully – daylight will often be enough to light a room in summer. Only turn on lights where you need them. Consider installing sensors and time switches to make sure lighting and appliances aren’t left on when not needed. For an additional saving, make sure all lights are fitted with energy efficient light bulbs.

Raise awareness

For energy saving measures to work, the whole team needs to be on board. Take a regular floor walk, so you can see first-hand where energy can be saved. Bigger companies might want to consider setting up a company “green team” to help spread the word about energy-saving measures.
