* **Improvement of thermal protection is profitable on the basis of the energy saved alone**. Other advantages, like increased comfort, better protection of the building substance, increase in value, security against risks of the international energy market and the contribution to climate protection are additional benefits. | * **Improvement of thermal protection is profitable on the basis of the energy saved alone**.

* **The annual cost of capital (repayment with interest) of the thermal protection measures, which serves as a measure of the economic efficiency, is based on the amount of energy saved**. The price for each kilowatt hour (kWh) of energy saved can be determined in this way. For all individual measures that were studied, the price was between 1 and 3.5 cents/kWh per kWh saved - much less than the final energy price of 4.5 cents/kWh for the year 2005 (see __**Table**__). By the end of 2005 and beginning of 2006, the energy price was already at 5.5 cents/kWh, which is the value assumed as the average future energy price in the study (see [[Basics: | * **The annual cost of capital (repayment with interest) of the thermal protection measures, which serves as a measure of the economic efficiency, is based on the amount of energy saved**.
