• Shut water off between washing your hands and rinsing.
• Use shower preferably, rather than bathing in a bathtub.
• Keep shower time short.
Air Condition and Refrigeration
• Air condition is per regulation not authorized for comfort use. However, if you have to manage an air condition in your area of responsibility, set it to the minimum required cooling temperature rather than to the maximum.
• Set the temperature of your refrigerator to 7° C. This temperature is most common for declaration of food expiration dates. To set temperatures below requires additional energy which results in additional cost.
