Top 10 Tips for Businesses

Keep exterior doors closed during cold and hot days to prevent the loss of heated air in the winter and cooled air in the summer
Turn off computer monitors, and other non-essential electronics when not in use.  A computer monitor uses up to 75% of the energy powering a computer, and other non-essential electronics can idle as much as 90% of the workday and are often left running on nights and weekends.
Enable ENERGY STAR® features on all computers (this feature is located in the Windows control panel under display settings)
Turn off photocopiers during off-hours and consider setting the copier to the energy efficient setting (operating photocopy equipment efficiently will reduce energy use by 25% or more)
Turn off lights when the sun will provide enough natural light and when areas are not in use (e.g. when leaving office area, copy rooms, break room, bathrooms, etc.)
Adjust lighting levels to match needs at different times – for example, full lighting may not be necessary after “public” hours
Double-side all printing by setting the default printing mode of your copiers and printers to duplex to reduce carbon emissions related to paper production and shipping
Clean radiators and baseboard heaters once a year to keep them running efficiently
Change filters in furnaces regularly – at least 2-3 times a month
Monitor energy bills to track energy savings resulting from these easy actions
