Make your business more energy efficient


To be more energy efficient:

  • turn off lights when not in use
  • replace standard light bulbs with compact LED lamps
  • upgrade older T12 lamps with more efficient T8 lamps with solid-state electronic ballasts
  • install sensors in locations to turn off when no one is present and on when people return

Heating and air conditioning

When it's cold:

  • adjust the thermostat to as low as is comfortable, the room will not heat up quicker just because the thermostat is turned to its highest setting
  • do not use extra electric heaters, they are expensive and can also be a fire hazard
  • keep curtains or blinds open at windows that face the sun to heat your office with solar radiation and reduce the pressure on your heating system
  • ensure heaters and vents are not blocked by furniture or other items
  • adjust your dress code according to the weather

When it's warm:

  • keep curtains or blinds closed to block direct sunlight from heating the building during warm days
  • open the windows in the evening
  • keep areas in front of vents clear 
  • keep external doors closed when the building’s air-con is on

Office equipment

To save energy when using office equipment, you should:

  • unplug battery chargers and any machines when not in use
  • use ‘stand-by’ features to turn off computers and monitors to reduce annual costs from £50 to £15, and this may also prolong the lifespan of the equipment
  • upgrade to laptops, they use less energy than desktops
  • always keep the AC adapter connected to a laptop, or unplug it when not needed for charging, to maximise savings
  • ensure equipment is off at night, weekends, and during holidays, even if you switch something to ‘stand by’ or ‘hibernation’ modes it will still use a small amount of energy

Essential maintenance

You should:

  • book your HVAC inspection at the beginning of heating and cooling season
  • ensure your air conditioning is adjusted both for heating and cooling, winter set to between 18°C and 21°C and summer set to 22°C
  • consider installing solar screens or solar films to your windows
  • plant vegetation around the buildings as this can keep them cool
  • avoid heating and cooling areas that are not frequently used

Empower your staff

You should:

  • make sure that everyone knows that saving energy will help the company, and ask your colleagues for their ideas on how you could all save energy
  • display posters, internal messaging and quick facts sharing energy saving tips
  • appoint a green ambassador within your company
