The earth needed 500 million years to produce the fossil fuels coal, oil, and gas with the help of solar energy.
In just a few hundred years, man will consume these valuable fuels without being able to replace them with other equivalent materials in the foreseeable future.
This film illustrates the urgent need to implement energy-saving measures in residential buildings.
The planning of energy-saving measures requires a high degree of expertise.
Only experts can comprehensively evaluate, plan, and implement these measures.
Energy consumption data and thermographic images provide the first concise indications of the necessary building renovation measures.
The Blower-Door method (see measuring device in the picture) additionally allows checking the tightness of the building.
