Savings: Building an energy “class A” house costs 10% more than building an ordinary house, but the investment will pay for itself in lower heating costs.
Remember this: There are only a few examples of the cost-effective construction of energy “class A” houses.
Reducing your carbon footprint: Building a 40 m2 energy-efficient and compact wooden house reduces your carbon footprint by nearly 9% per year. If a million Finns did this, it would save the equivalent of 87,000 carbon footprints. Emissions decrease because power plants need to produce less heat, and resource-wise materials are used for construction.
