Savings: A good rule of thumb is that one degree in temperature is equivalent to 5% in heating costs. House owners could see the savings in their next energy bill. In apartment buildings, it reduces the pressure to raise maintenance fees and rents.
Remember this: Finns are accustomed to dressing lightly in their warm homes. Lowering the temperature doesn’t mean you have to be uncomfortable, because wearing socks and a long-sleeved shirt is enough to keep you warm despite a lower temperature.
Reducing your carbon footprint: Lowering the temperature of your home by two degrees would reduce your carbon footprint by 1.2% each year. If a million Finns did this, it would save the equivalent of 12,000 carbon footprints.
