Why is energy advice for residential and non-residential buildings worth it?

Not every renovation measure automatically leads to the desired result. If you plan incorrectly, you not only waste time but, in the worst case, also waste money on unsuccessful modernizations. But there is another way: If you perfectly coordinate the heating technology, building envelope, etc., you can drastically reduce your energy costs and avoid unnecessary improvements. At the same time, you make an important contribution to climate protection and increase the value of your property. 

In order to make the most of your savings potential and government funding, professional support is necessary
